  • Sets alerts when health status changes.

Govern

Azure Cost Management

Cost Management for Amazon Web Services (AWS)

Adopting a multi-cloud strategy usually results in high complexity in cost control, often given by the different management of different cost models and different billing cycles. Keeping the costs of workloads residing on different cloud providers under control can be difficult to understand as they require the use of different dashboards and views.

Azure Cost Management introduced the ability to centrally manage AWS costs in addition to Azure. This feature allows you to avoid budget surpluses, to maintain control and better manage cloud cost responsibility.

Secure

Azure Security Center

Introduction to Azure Defender

Threat protection services in the Azure Security Center have been renamed to Azure Defender. Furthermore, thanks to the new dashboards, a better experience is offered for detecting security threats and their responses.

Securing SQL databases and virtual machines at any location

With Azure Arc support, Azure Defender can now protect SQL servers located on-premises and in multicloud environments, as well as virtual machines hosted in other public clouds.

Advanced protection for containers

The growing popularity of the adoption of containers and Kubernetes has led to an evolution in Azure Defender for Kubernetes. In fact,, to ensure adequate workload protection in the Kubernetes environment, Azure Defender has included Kubernetes policy management, hardening and application of admission controls.

Furthermore, thanks to the introduction of a mechanism that allows continuous scanning of container images, the possibility of maliciously exploiting the running containers is reduced to a minimum.

IoT protection

Azure Defender for IoT, thanks to the recent acquisition of CyberX, can provide security for IoT devices in agentless mode. The solution provides continuous detection of IoT assets / OT, vulnerability management and threat monitoring for both greenfield and brownfield devices.

Protect

Azure Backup

Backup Center

The new Backup Center solution, currently available in public preview, provides a unique experience designed for centralized backup management at scale. With Backup Center, you can dynamically explore large backup inventories between vaults, subscriptions, locations and even different tenants. The Backup Center can also govern any actions related to backups.

Backup Center supports the following types of workloads:

  • Azure Virtual Machines
  • SQL in Azure Virtual Machines
  • Azure Database for PostgreSQL servers
  • Azure Files

Cross Region Restore

Recovery between different Azure regions, available for virtual machines, has also been extended to support SQL and SAP HANA. Cross Region Restore allows customers to restore their data to secondary regions at any time, essential in the event of the unavailability of the primary region.

Long-term protection of Azure Database for PostgreSQL

Azure Backup and Azure Database Services have merged to provide an enterprise-class backup solution for Azure Database for PostgreSQL (preview). Through managed backup policies you can enable backup retention for up to ten years.

Microsoft announced several important additions to its Azure infrastructure as a service (IaaS) portfolio and the Microsoft infrastructure services continue to evolve to optimize the experience of running business-critical workloads.

Azure

Compute

Availability Zones deployed to more Azure Regions

Azure Availability Zones (AZs) provide a high-availability option for comprehensive business-continuity and disaster-recovery strategies (BCDR), 99.99% uptime service-level agreement (SLA) on virtual machines, flexible high-performance architecture and multizone support with built-in security. Microsoft continues to expand deployment of Availability Zones in datacenter regions worldwide, with a roadmap to provide Availability Zone options in each country it operates datacenters in over the next 24 months. In September, Availability Zones will be available in two more existing regions, Canada Central and Australia East, bringing the total number of Microsoft’s AZ-enabled regions to 14.

Zone to zone disaster recovery for azure virtual machines

Zone to Zone disaster recovery allows customers to replicate, failover and failback their business-critical virtual machines within the same region with zones. The capability adds options for scenarios such as metro-based disaster-recovery strategy while customers are hosting applications on-premises and are looking to mimic that after migrating applications over to Azure; those that have complicated networking infrastructure and want to avoid the cost and complexity of recreating it in a secondary region; and those in regions that prefer not to use paired region disaster recovery options.

New Azure Spot VM features

New Azure Spot VM features, in preview soon in the Azure portal, enable customers to access and review the price history of Spot VMs and eviction rate for the past 28 trailing days. Also, not only allow customers to derive estimates about the probability that their workloads will be evicted, but also enable better estimates for the cost of running interruptible workloads using Spot VMs.

Azure Hybrid Benefit for Linux workload (preview)

Azure Hybrid Benefit, available in preview, improves flexibility and enhances user experience for Red Hat and SUSE customers migrating Linux to Azure.Directly in the portal or through CLI, Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES) customers will be able to convert existing Linux VMs from pay-as-you-go (PAYG) billing to bring-your-own-subscription (BYOS) billing, making use of their existing Red Hat and SUSE subscriptions. This is a unique capability that allows customers to first deploy a POC in Azure using the convenience of on-demand PAYG Linux VMs, and when testing is complete, convert it to long-term production using RHEL and SLES subscriptions. This removes the headache of production redeployment, preserves existing investments in on-premises RHEL and SLES subscriptions, and reduces migration planning worries.

A new Azure-supported Linux distribution

Flatcar Container Linux by Kinvolk, is now available in Azure Marketplace. Flatcar is an immutable Linux distribution and is compatible with Core OS (which reached its end of service on May 26, 2020), making Flatcar Container Linux a viable and straightforward migration choice for container workloads running on Azure.

Azure Image Builder

Azure Image Builder, generally available by the end of this year, is a free image-building service that streamlines the creation, update, patch, management and operation of Linux and Windows images. Azure Image Builder will deploy resources into your subscription when used, and you pay only for the virtual machines and associated storage and networking resources consumed when running your image-building pipeline.

Multiple new Azure Infrastructure features

Multiple new Azure Infrastructure features are now available:

  • New Azure Virtual Machines (VMs) are now generally available featuring Intel Cascade Lake processors for general purpose and memory-intensive workloads. These VMs provide up to 20% greater CPU performance compared to the prior generation.
  • Azure Dedicated Host now gives customers more control. Customers can schedule host maintenance operations on Dedicated Hosts and isolated VMs as well as control when guest OS image updates are rolled out. Azure Dedicated Host also supports Virtual Machine Scale Sets and simplifies deployment by offering customers the ability to let the platform select the host group where VMs are deployed to.

The NVIDIA T4 Tensor Core GPU provides visualization, inferencing, and machine learning for less compute intense workloads

The new way to keep Windows virtual machines up to date in Azure

Common corporate cybersecurity practices involve timely application of software updates that eliminate vulnerabilities that enable the implementation of specific cyberattacks on business systems. To facilitate the application of patches to virtual machines located in Azure, Microsoft recently announced the availability of a new feature called "Automatic VM guest patching". This article describes the characteristics and peculiarities of this solution that helps simplify the management of updates and achieve compliance in the security field.

The main features of Automatic VM guest patching are the following:

  • Are automatically downloaded and applied to virtual machines in Azure patches classified as Critical or of security.
  • Patches are applied during non-peak hours considering the time zone set on the virtual machine.
  • Patch orchestration is managed by the Azure platform and patches are applied taking into account the native Azure availability principles.
  • The health of the virtual machine, determined through Azure platform health signals, is monitored to detect any errors in the application of patches.
  • Works for all Windows virtual machines, regardless of the configured size.

How to Install Updates on Windows Virtual Machines

Azure Windows Virtual Machines, thanks to the introduction of this new feature, support three different ways to install updates:

  • Automatic managed by the operating system (Automatic Updates). This is the default method set for Windows virtual machines.
  • Automatic managed by the Azure platform. This is the mode recently introduced and described in this article. This mode provides for the disabling of automatic updates on board the virtual machine. Enabling this mode on the virtual machine will install the extension CPlat.Core.WindowsPatchExtension, fully managed by the Azure platform.
  • Manual. This mode, configured when different system patching solutions are adopted, disabling Automatic Updates.

Figure 1 – Choices for installing patches when creating a new VM

Requirements

Enabling the feature Automatic VM guest patching requires that the following requirements be met on the virtual machine:

  • The Azure VM Agent must be installed.
  • The Windows Update service must be running.
  • Windows Update or Windows Server Update Services server endpoints must be reachable (WSUS).
  • Compute APIs must be version 2020-06-01 or higher.

How the auto-update mechanism works?

Enabling the feature Automatic VM guest patching only critical and security-classified patches are automatically downloaded and applied to the system. This periodic update process starts automatically every month when new patches are released through Windows Update. The scanning mechanism ensures that all missing patches on the system are discovered as soon as possible, updates can be installed at any day during off-peak hours, and it happens within 30 days after Microsoft's monthly release of updates. This means that you do not have complete control over when you install updates. The upgrade process also involves restarting the virtual machine if it is required by patching.

The patch installation process is orchestrated globally by Azure for all virtual machines on which is enabled the feature Automatic VM guest patching and the principles of availability provided by Azure are covered.

For a group of virtual machines involved in the upgrade process, Azure platform will orchestrate updates taking into account the following principles.

Cross-distribution of updates on regions:

  • To avoid errors globally in the distribution of updates, they will be released gradually on the different regions.
  • An update phase can affect one or more regions and it can move on to the next phases only if the updates are completed successfully.
  • The geo-paired regions are never updated at the same stage to avoid the simultaneous installation of updates.

Deploying updates within a region:

  • VMs residing in different Availability Zones are not updated at the same time.
  • VMs that are not part of an Availability Zones are grouped together to prevent updates from being distributed simultaneously on all VMs belonging to a specific subscription.

Deploying updates within an Availability Zone:

  • VMs belonging to the same Availability Zones are not updated at the same time and updates will be installed in accordance with the Update Domain principle.

Conclusions

This new method provided by the Azure platform allows you to keep Windows systems updated in a simple way, direct and with very little administrative effort. However, often there is a need to have much greater control regarding the distribution of updates on systems and in the Azure environment it is possible to adopt the alternative and more complete solution called Update Management. This solution, compared to the feature Automatic VM guest patching, allows you to have total visibility on the compliance of updates for both Windows and Linux systems and allows you to schedule deployments for the installation of updates by defining specific maintenance windows.

Azure IaaS and Azure Stack: announcements and updates (September 2020 – Weeks: 37 and 38)

This series of blog posts includes the most important announcements and major updates regarding Azure infrastructure as a service (IaaS) and Azure Stack, officialized by Microsoft in the last two weeks.

Azure

Compute

Azure Virtual Machines DCsv2-series are available in Southeast Asia

Confidential computing DCsv2-series virtual machines (VMs) are available in Southeast Asia in multiple availability zones.

Storage

Azure Blob storage object replication

Object replication is a new capability for block blobs that lets you replicate your data from your blob container in one storage account to another anywhere in Azure.

Object replication unblocks a new set of common replication scenarios:

  • Minimize latency: users consume the data locally rather than issuing cross-region read requests.
  • Increase efficiency: compute clusters process the same set of objects locally in different regions.
  • Optimize data distribution: data consolidated in a single location for processing/analytics and then distribute only resulting dashboards to your offices worldwide.
  • Minimize cost: tier down your data to Archive upon replication completion using lifecycle management policies to minimize the cost.

Change feed support is generally available for Azure Blob Storage

Change feed provides a guaranteed, ordered, durable, read-only log of all the creation, modification, and deletion change events that occur to the blobs in your storage account. Change feed is the ideal solution for bulk handling of large volumes of blob changes in your storage account, as opposed to periodically listing and manually comparing for changes. It enables cost-efficient recording and processing by providing programmatic access such that event-driven applications can simply consume the change feed log and process change events from the last checkpoint.

Azure Blob storage lifecycle management now supports append blobs

Azure Blob storage lifecycle management offers a rich, rule-based policy for Azure storage accounts. You can use the policy to transition your data to the appropriate access tiers or expire at the end of the data’s lifecycle. Azure Blob storage lifecycle management now supports expiration of append blobs.

Azure Blob access time tracking and access time-based lifecycle management (preview)

Once access time tracking is enabled, each blob has a new property called last access time which is updated when the blob is read. Azure Blob lifecycle management supports using last access time as a filter to transition data between access tiers and manage data retention. You can minimize your storage cost automatically by setting up a policy based on last access time to:

  • Transition your data from a hotter access tier to a cooler access tier (hot to cool, cool to archive, or hot to archive) if there is no access for a period.
  • Transition your data from the cool tier to the hot tier immediately if there is an access on the data.
  • Delete your data if there is no access for an extended period.

NFS 4.1 support for Azure Files (preview)

NFS file system is very popular choice for Linux applications and end users for their shared storage needs. Having a fully managed NFS file system in Azure will enable customers to easily lift-and-shift their enterprise workloads and leverage the elasticity, scale and cost savings of cloud. Azure Files is built on Azure Storage platform which by nature is highly durable, highly available and highly secure. It is backed by same Azure Storage SLA. NFS on Azure Files is being offered first on the highly performant SSD backed Premium Files tier enabling customers to run their most demanding enterprise applications. The NFS file system can grow and shrink to meet your scale and performance requirement from 100 GiB to 100 TiB per volume. Azure Files NFS can be accessed from a variety of clients like Azure VM Linux distros like Ubuntu, RHEL, SUSE etc., Azure Kubernetes Service(AKS), Azure Container Instances (ACI), Azure VMWare Service (AVS), VMSS, etc. NFS has a broad range of use cases. 

Azure NetApp Files: cross region replication (preview)

With this new disaster recovery capability, you can replicate your Azure NetApp Files volumes from one Azure region to another in a fast and cost-effective way, protecting your data from unforeseeable regional failures.

The new Microsoft solution for hyper-converged scenarios

Very frequently to the strong tendency to move workloads to the public cloud for cost benefits, efficiency and innovation, alongside the need to maintain specific on-premises application environments. The reasons can be different and range from compliance reasons, specific needs in terms of latency or for certain business reasons. Microsoft, aware of these needs, recently announced the release of a new version of Azure Stack HCI, the solution that allows you to build a hyper-converged infrastructure (HCI) to run virtual machines in an on-premises environment and that involves an easy and strategic connection to Azure services. This article lists the main features that will be introduced in the new version of Azure Stack HCI.

What is Azure Stack HCI?

With the arrival of Windows Server 2019, Microsoft introduced the solution Azure Stack HCI, which allows the execution of virtual machines and a wide access to different services offered by Azure.

This is a hyper-converged infrastructure (HCI), where different hardware components are removed, substitutes from the software, able to combine the layer of compute, storage and network in one solution. In this way there is a transition from a traditional "three tier" infrastructure, composed of network switches, appliance, physical systems with onboard hypervisors, storage fabric and SAN, toward hyper-converged infrastructure (HCI).

Figure 1 – "Three Tier" Infrastructure vs Hyper-Converged Infrastructure (HCI)

Azure Stack HCI belongs to the Azure Stack family, which includes a comprehensive and flexible range of solutions to meet the different needs for implementing infrastructure. The Azure Stack portfolio ranges from Azure Stack Hub, which is an Azure extension that can bring the agility and innovation of cloud computing to the on-premises environment, to Azure Stack Edge, a managed Azure appliance that can bring computational power, cloud storage and intelligence in a remote edge of the customer. For more information about the Azure Stack portfolio, see this article.

Figure 2 – Azure Stack portfolio

The new Azure Stack HCI solution, deployed as an Azure hybrid service is named Azure Stack HCI version 20H2 and includes important news.

Figure 3 - Overview of Azure Stack HCI version 20H2 components

Full stack for a Hyper-Converged infrastructure

The operating system of the new Azure Stack HCI solution is based on the core components of Windows Server and has been specially designed and optimized to provide a powerful Hyper-converged platform. The new version of Azure Stack HCI adopts well-established Windows Server technologies such as Hyper-V, software-defined networking and Storages Spaces Direct, and adds new specific features. Following, the innovation areas of this solution are reported.

Dedicated and solution-specific operating system

The operating system of the new solution Azure Stack HCI it is a specific operating system with a simplified composition and newer components than Windows Server 2019.

This operating system does not include roles that are not required for the solution, such as the print server, DNS role, DHCP server, Active Directory Domain Services, services relating to certificates and federated services.

Furthermore, there is the most recent hypervisor also used in the Azure environment, with software-defined networking and storage technologies optimized for virtualization.

The local user interface is minimal and is designed to be managed remotely.

Figure 4 - Azure Stack HCI OS interface

Disaster Recovery Features and virtual machine failover inherent in the solution

In the new version of Azure Stack HCI is included the ability to create stretched clusters to extend a cluster of Azure Stack HCI in two different locations (rooms, buildings or even two cities). This feature provides a replica of storage (synchronous or asynchronous) and contemplates encryption, on-premises site resiliency and automatic failover of virtual machines.

Figure 5 – Stretched cluster in a hyper-converged Azure Stack HCI architecture

In the build phase of creating a new cluster, you can select whether it is an implementation on a single site or stretched on two different sites.

Figure 6 – Options when creating an Azure Stack HCI cluster

If there is a stretched cluster, when creating a volume, you can configure storage replication between the two sites.

Figure 7 – Volume replication options when there is stretched cluster

Optimized the Storage Spaces resync process

In Azure Stack HCI version 20H2 has been completely re-engineered the Storage Spaces Resync, used for storage space repair, to the point where the length of the process is significantly reduced (up to 4-5 times). This improvement makes it possible to speed up the restart of the various systems after the updates are applied.

Figure 8 - Comparison of the times for the monthly application of operating system patches

Updates of the entire stack covered by the solution (full-stack updates)

To reduce the complexity and operational costs of the solution update process, in the new version of Azure Stack HCI a process is contemplated that involves full-stack updating (Firmware / driver along with the operating system) for certain selected partners.

Figure 9 – Solution updates of a Dell EMC-branded Azure Stack HCI solution

Azure Hybrid Service

This new version of Azure Stack HCI is provided as an Azure service, applying a subscription-based licensing model and offering integrated hybrid capabilities.

To expand the capabilities of your solution, you can use Azure solutions to monitor, activate disaster recovery scenarios, manage backup protection, as well as a centralized view of the various implementations of Azure Stack HCI direct from the Azure Portal. Following, details about this Azure hybrid service are reported.

Native integration in Azure

The new Azure Stack HCI natively integrates with Azure services and Azure Resource Manager (ARM). No agent is required for this integration, but Azure Arc is integrated directly into the operating system. This allows you to view, direct from the Azure Portal, the cluster Azure Stack HCI on-premises exactly like an Azure resource.

Figure 10 – Azure Stack HCI integration scheme in Azure

By integrating with Azure Resource Manager, you can take advantage of the following benefits of Azure-based management:

  • Adopting Standard Azure Resource Manager-Based Constructs (ARM)
  • Classification of Clusters with Tags
  • Organizing Clusters in Resource Groups
  • Viewing all clusters Azure Stack HCI in one centralized view
  • Managing access using Azure Identity Access Management (IAM)

Billing based on a subscription model

Despite being running on-premises, Azure Stack HCI provides invoicing based on Azure subscription, just like any other Azure cloud service. The model is simple and has a cost of 10$ / core / Month, which depends on the cores of the physical processor. In the new pricing model there is no minimum or maximum on the number of licensed cores, much less in the activation duration.

Figure 11 – New licensing model applied for Azure Stack HCI

  • A family of network adapters

Furthermore, you can customize your hardware solution to suit your needs, going to configure the processor, memory, storage and features of network adapters, always respecting the supplier's compatibility matrices.

Figure 12 – Hardware composition for Azure Stack HCI solutions

Management and integration tools

The administrative management of Azure Stack HCI does not require specific software, but you can use existing management tools such as Admin Center, PowerShell, System Center Virtual Machine Manager and even third-party tools.

Using the Windows Admin Center, you can install and configure new architectures Azure Stack HCI and activate virtual systems. Furthermore, With native Windows Admin Center integration with Azure, you can extend functionality with different Azure services, including:

  • Azure Site Recovery to implement disaster recovery scenarios.
  • Azure Monitor to monitor, in a centralized way, what happens at the application level, on the network and in its hyper-converged infrastructure, with advanced analysis using artificial intelligence.
  • Azure Backup for offsite protection of your infrastructure.
  • Azure Security Center for monitoring and detecting security threats in virtual machines
  • Azure Update Management to make an assessment of the missing updates and proceed with its distribution, for both Windows and Linux systems, regardless of their location, Azure or on-premises.
  • Cloud Witness to use Azure storage account as cluster quorum.

Conclusions

The innovations introduced in Microsoft's new hyper-converged solution are very interesting and concern various areas. Azure Stack HCI integrates seamlessly with the existing on-premises environment and offers an important added value: the ability to connect Azure Stack HCI with Azure services to achieve a hybrid hyper-converged solution. This aspect in particular strongly differentiates it from other competitors who offer solutions in this area. Thanks to the changes introduced by this new version it is possible to obtain a complete and more integrated and performing proposition for hyper-converged scenarios.

Azure Blob Versioning automatically maintains previous versions of an object and identifies them with version IDs. You can list both the current blob and previous versions using version ID timestamps. You can also access and restore previous versions as the most recent version of your data if it was erroneously modified or deleted by an application or other users.

Networking

Azure DNS: Introducing automatic child zone delegation

A new update released to general availability in all clouds that makes it easier for you to create Child Zones which are easily attached to Parent Zones. Prior to this release, when a customer was creating a new child zone, they would add their resource records to the newly created zone but often missed the step adding the complicated nameserver records back to the parent zone, causing name resolution failure when the customer would try to test the newly created zone.  This update creates an option for you to identify their new zone as a child (please see illustration) of an existing zone in Azure DNS. When this selection has been made, the name server records for the child zone will be automatically populated in the parent, saving you 4 additional steps. For a quick explanation on how to create child zones, please check out our tutorial guide.

Upcoming changes to Standard Public IPs and Standard Load Balancers

With Network API version 2020-08-01, zone behavior for Standard SKU resources (Azure Load Balancer and Public IP addresses) will be updated such that:

  • when no zone is specified, a non-zonal resource is created
  • when a single zone is specified, a zonal resource is created 
  • when multiple zones are specified in a region with Availability Zones, a zone-redundant resource is created

A zone-redundant resource can only be created in regions where Availability Zones are supported. 

Azure Stack

Monitor

Azure Monitor

New version of the agent for Linux systems

A new version of the Log Analytics agent has been released this month for Linux systems. In addition to solving several issues, some new features are introduced, among the main ones we find:

  • Support for Red Hat Enterprise Linux 8
  • Support for Azure Arc for servers
  • FIPS compliance
  • Limiting ingestion to prevent service degradation in the event of extremely high data volume

Azure Monitor for containers: support for viewing Kubernetes environment resources (preview)

With the Kubernetes resource monitor from the Azure portal, you can now use the kubernetes “point and click” to get real-time details of workloads hosted in the AKS environment. The public preview of this feature includes support for different resources (deployments, pods, and replica sets) and supports the following features:

  • Viewing Workloads Running on the Cluster, including the ability to filter resources by namespaces
  • Find the node on which an application is running and its IP address of the pod
  • View pods in set replica, the status of each pod and the images associated with each pod
  • Drill down for individual deployments to view their real-time status and details
  • Perform on-the-fly changes on YAML to validate devtest scenarios

Audit Logs for Azure Monitor queries (preview)

The Azure Monitor team has announced in public preview one of the most requested features: the ability to check Azure Monitor query logs. When enabled, through the Azure diagnostic mechanism, you can collect telemetry data about who ran a query, when it was performed, which tool was used to run it, text and performance statistics related to the performance of the same. This telemetry, like any other Azure Diagnostic-based telemetry, can be sent to an Azure storage blob, Event Hub or Azure Monitor.

New dedicated blade for System Center

System Center now has its own dedicated blade in Log Analytics. To display the new System Center panel, you need to access the Log Analytics workspace and select “System Center” from the left navigation bar, in the group “Workspace Data Sources”. The new System Center blade lets you view and manage SCOM instances connected to your Log Analytics workspace.

New limits for data ingestion in Log Analytics

Azure Monitor is a large-scale service designed to serve thousands of customers who send high volumes of data every month at an increasing rate. As with any multi-tenancy platform, Microsoft has realized that limits must be placed to protect customers from sudden spikes in ingestion that can affect customers who share the environment and resources. Until now, there was only one import volume speed limit for Azure resource data from Diagnostic Settings. Now you've added the limit to other Log Analytics data sources, including: Diagnostic Settings, agents and data collection APIs. The limit is applied to compressed data approximated 6 GB / Min, where this limit may vary depending on the types of data and its compression ratio. This limit for import volume speed in Log Analytics can be increased by opening a support request.

Log Analytics REST APIs: released a new version

The new version (2020-08-01) of the Log Analytics REST API for the resource provider OperationalInsights was released. This version supports new features such as customer-managed keys(CMK), Bring Your Own Storage (BYOS) and consolidates the functionality of all previous versions.

  • Cost Optimization
  • Faster backup and restore operations

Configuring Azure file shares

Azure Backup has simplified the backup configuration experience for Azure file shares, providing the ability to enable backup directly from the file share management panel.

Configuring Azure file shares backup now consists of only the following two steps:

  • Creating or choosing the recovery services vault
  • Create or choose the backup policy

Improvements in virtual machine protection

Azure Backup introduces the following improvements in the protection of VMs:

  • Introduces the ability to restore unmanaged disks of a VM by turning them into managed disks during the restore phase.
  • Supports the backup and restore of Virtual Machine Scale Sets in the orchestration mode described in this document.
  • Allows disk replacement as an option for VMs that have assigned Managed Service Identities (MSI).

Encryption of backups using customer managed keys (preview)

Azure Backup introduces the possibility, when you back up Azure Virtual Machines, to encrypt data using proprietary and managed keys. Azure Backup allows you to use RSA keys stored in Azure Key Vaults to encrypt backups. The data will then be protected using a data encryption key (DEK) AES-based 256, which in turn is protected using keys stored in Key Vaults. This gives you full control over the data protection and keys that are used for encryption.

SAP HANA backup for Red Hat Enterprise Linux VM

Azure Backup has released the ability to protect SAP HANA databases on Red Hat Enterprise Linux virtual machines (RHEL). This feature allows to have in an integrated way and without having to provide a specific backup infrastructure, the protection of SAP HANA databases on RHEL, one of the most commonly used operating systems in these scenarios.

Cloud Governance: how to control cloud costs through budgets

In the public cloud, the simplicity of delegation and the consumer-related cost model exposes companies to a risk of loss of control over them. Always having a supervision on the expenses to be incurred for the resources created in the cloud environment therefore becomes an aspect of fundamental importance to implement an effective governance process. The solutionAzure Cost Management provides a comprehensive set of cloud cost management features, including the ability to set up budgets and expense alerts. This article describes how to best use budgets to proactively control and manage cloud service costs.

Budgets are spending thresholds that can be set in the solution Azure Cost Management + Billing, capable of generating notifications when they are reached. Cost and resource utilization data are generally available within 20 hours and budgets are evaluated against these costs each 12-14 hours.

The procedure for setting budgets from the Azure portal involves the following steps.

Figure 1 – Add a budget from Cost Management

Figure 2 – Parameters required when creating budgets

During the budget configuration phase, you must first assign the scope. Depending on the type of Azure account, you can select the following scopes:

  • Azure role-based access control (Azure RBAC)
    • Management groups
    • Subscription
  • Enterprise Agreement
    • Billing account
    • Department
    • Enrollment account
  • Individual agreements
    • Billing account
  • Microsoft Customer Agreement
    • Billing account
    • Billing profile
    • Invoice section
    • Customer
  • AWS scopes
    • External account
    • External subscription

For more information about the use of scopes, see this Microsoft's document.

To create a budget that aligns with the billing period, you can select a reset period for the month, quarter or year of billing. If, on the other hand, you intend to create a budget aligned to the calendar month, you must select a reset period monthly, quarterly or yearly.

Later, it is possible to set the expiration date from which the budget becomes invalid and its cost evaluation is interrupted.

Based on the fields you choose when you define your budget, a chart is shown to help you set the spending threshold to be used. By default, the suggested budget is based on the higher expected cost that could be incurred in future periods, but the budget amount can be changed to suit your needs.

After you set up your budget, you are prompted to configure your alerts. Budgets require at least one cost threshold (% budget) and an email address to use for notifications.

Figure 3 – Configure alerts and e-mail addresses to use for notifications

For a single budget, you can include up to five thresholds and five email addresses. When a budget threshold is reached, email notifications are normally sent within an hour of the evaluation.

When creating or editing a budget, but only if the scope defined for the same is a subscription or a resource group, you can configure it to invoke an Action Group. TheAction Group allows you to customize notifications to suit your needs and can perform various actions when the budget threshold is reached, including:

  • Voice call or text message (for enabled countries)
  • Sending an email
  • Calling a webhook
  • Sending data to ITSM
  • Recalling a Logic App
  • Sending a push notification on mobile app of Azure
  • Running a runbook of Azure Automation

Figure 4 – Associating an Action Group when a threshold is reached

After you finish creating a budget, you can view it in the respective section.

Figure 5 – Budget created and its percentage of usage

The visualization of the budget with respect to the expenditure trend is one of the first actions that is generally taken into consideration in the cost analysis phase.

Figure 6 – View budget in cost analysis

When a certain threshold is reached in a budget, in addition to the notifications you set, an alert is also generated in the Azure portal.

Figure 7 – Alert generated when a certain threshold is reached

When the budget thresholds that you create are exceeded, notifications are triggered, but none of the cloud resources are changed and as a result consumption is not interrupted.

Integration with Amazon Web Services (AWS) Cost and Usage report (CUR) you can monitor and control AWS costs in Azure Cost Management and define budgets for AWS resources too.

The Cost of the Solution

You can use Azure Cost Management for free, in all its features, for the Azure environment. As for the management of AWS costs is expected, in the final release, a charge equal to 1% of total spend managed for AWS. For more details on the cost of the solution you can consultthe pricing of Cost Management.

Conclusions

Cost control is a key component to maximize the value of your cloud investment. By using budgets, you can easily activate an effective mechanism to proactively control and manage the costs of cloud services located on both Microsoft Azure and Amazon Web Services (AWS).
