The new VMware solution in the Microsoft Public Cloud

In the current economic context, many companies face new challenges to adopt flexible and economical solutions that allow for greater stability, continuity and resiliency for key application workloads that support their core business. It was recently announced that Azure VMware Solution (AVS) the new service designed, built and supported by Microsoft, and approved by VMware, which allows customers to easily extend or completely migrate their VMware applications residing on-premises to Azure. This article lists the key aspects of this solution that benefits from the efficiency of Microsoft's public cloud, while maintaining operational consistency with the VMware environment.

Features of the solution

Azure VMware Solution (AVS) is a service that enables provisioning and execution of an environment VMware Cloud Foundation full on Azure. VMware Cloud Foundation is VMware's hybrid cloud platform for managing virtual machines and orchestrating containers, where the entire stack is based on a hyperconverged infrastructure (HCI). This architecture model ensures consistent infrastructure and operation across any private and public cloud, including Microsoft Azure.

The solution Azure VMware allows customers to adopt a full set of VMware features, with the guarantee of holding the validation "VMware Cloud Verified". This solution helps to achieve consistency, performance and interoperability for existing VMware workloads, without sacrificing speed, scalability and availability of Azure global infrastructure.

An Azure VMware Solution Private Cloud includes:

  • Dedicated bare-metal servers provided with ESXi VMware hypervisor
  • vCenter server for managing ESXi and vSAN
  • VMware NSX-T software defined networking for vSphere vMs
  • VMware vSAN datastore for vSphere vMs
  • VMware HCX for workload mobility management

On these infrastructures, it will be possible to create, deploy or migrate VMware virtual machines, but with the advantage of also using the various services offered by Azure.

All Azure Private Clouds currently come with the following software and hardware specifications:

Figure 3 – Azure VMware Solution software and hardware specifications

Azure Private Cloud infrastructure contains vSphere clusters on dedicated bare metal systems, able to scale from 3 to 16 host. It also provides the ability to have multiple clusters in a single Azure Private Cloud. The hosts are high-end and equipped with two Intel processors 18 cores from 2,3 GHz and 576 GB RAM.

Storage

Azure Private Clouds provide cluster-level storage using software-defined technology vMware vSAN. All local storage of each host in a cluster is used in a vSAN datastore and at-rest data encryption is enabled by default. The vSAN datastore also enables deduplication and data compression. Hosts have two vSAN diskgroups with a total raw capacity of 15,36 TB (SSD disks) and a vSAN cache from 3,2 T B (NVMe disks). The raw capacity of a cluster is the capacity per host multiplied by the number of nodes. You can use Azure storage to extend the storage capacity of these private clouds. For more information about storage, see the Microsoft-specific documentation.

Networking

When you activate an Azure Private Cloud with Azure VMware Solution private networks are created for management, provisioning and vMotion functionality. Access to the private cloud from on-premises environments uses ExpressRoute Global Reach for a private and secure connection.

For further information on networking, see the Microsoft documentation.

Access and security

In order to achieve greater security, Azure VMware solution's private clouds use vSphere role-based access control. vSphere SSO LDAP features can be integrated with Azure Active Directory. For more information on this, see this Microsoft's document.

Management of updates and maintenance of the solution

One of the main advantages of this solution is that the platform is maintained by Microsoft and automatic and regular updates are included, providing the latest feature sets and increased security and stability.

The components of the Azure VMware solution that are subject to the updates are as follows::

  • vCenter and ESXi
  • vSAN
  • NSX-T
  • Underlying hardware with bare metal node and network switch drivers and firmware

The following updates are applied to the Azure VMware solution:

  • Security and bug fixes released by VMware.
  • Major and minor version updates of VMware components.

In addition to performing updates, the Azure VMware solution also provides a backup of the configuration of the following VMware components:

  • vCenter Server
  • NSX-T Manager

More details about maintenance and platform updates can be found in this Microsoft article.

Support and Responsibility

Azure VMware Solution is validated, supported and certified by VMware and Microsoft. The support of the solution is provided by Microsoft which is always the first and only point of contact for the customer. If necessary, Microsoft will coordinate with VMware support for specific issues regarding VMware solutions.

Azure VMware Solution uses a shared responsibility model according to the following matrix:

Solution availability

The solution can be adopted in production environments and is currently available in a limited number of Azure regions:

Solution monitor

The complete monitor of the solution can be done via Azure Monitor and, after the solution is activated in the Azure subscription, automatically starts collecting its logs. In addition, you can install the Azure Monitor agent on Linux and Windows virtual machines hosted in the private clouds of the Azure VMware solution, you can also enable the Azure diagnostics extension.

Main adoption scenarios

The Azure VMware solution can be adopted to address the following scenarios:

  • Need to expand your datacenter
  • Disaster recovery and business continuity
  • Application Modernization
  • Reduction, consolidation or decommissioning of your datacenter.

Thanks to this solution, you can redistribute your VMware-based virtual machines in a non-destructive way, automated, scalable and highly available without changing the underlying vSphere hypervisor. Systems can be migrated by adopting native VMware solutions (VMware HCX) or using Azure Migrate.

Benefits of the solution

Among the main benefits of adopting this solution it is possible to mention:

  • Ability to take advantage of investments already made in the skills and tools for managing on-premises VMware environments.
  • Modernization of your application workloads by adopting Azure services and without facing interruptions.
  • Convenience especially for running Windows and SQL Server workloads. In fact, customers who adopt this solution are entitled to three years of free extended security updates for versions 2008 of Windows Server and SQL Server. In addition, being in effect an Azure service, Azure VMware Solution supports Azure Hybrid Benefits, that allow you to maximize the investments made in local Windows Server and SQL Server licenses during the migration or extension to Azure. Finally, you can get a financial benefit by buying Reserved Instances (to 1 or 3 years) to save on the cost of the Azure VMware Solution.

Conclusions

Thanks to the close collaboration between Microsoft and VMware, the new solution offers customers who already have an on-premises VMware environment the same possibilities also in the Microsoft public cloud, being able to adopt the wide range of services offered by Azure. With this solution, you can take advantage of a consistent operating model that can increase agility, deployment speed and resiliency of your business critical workloads.
