Azure IaaS and Azure Stack: announcements and updates (September 2023 – 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.



Latest generation burstable VMs – Bsv2, Basv2, and Bpsv2

The Bsv2, Basv2, and Bpsv2 series virtual machines represent the latest generation of Azure burstable general-purpose VMs. These VMs provide a baseline level of CPU utilization and can expand to higher CPU utilization as workload volume increases. They are ideal for various applications, including development and test servers, low-traffic web servers, small databases, microservices, proof-of-concept servers, build servers, and code repositories. Compared to the B series v1, these new B series v2 virtual machines offer up to 15% better price-performance, up to 5X higher network bandwidth with accelerated networking, and 10X higher remote storage throughput.


Sensitive Data Protection for Application Gateway Web Application Firewall

Azure’s regional Web Application Firewall (WAF) running on Application Gateway has introduced support for sensitive data protection through log scrubbing. When a request aligns with the criteria of a rule and activates a WAF action, the event is documented within the WAF logs. These logs are maintained as plain text for easier debugging. However, this means that any patterns matching sensitive customer data, such as IP addresses, passwords, and other personally identifiable information, could potentially be recorded in the logs as plain text. To enhance the security of this sensitive data, users can now establish log scrubbing rules that substitute the sensitive data with “******”. The sensitive data protection feature using log scrubbing facilitates the creation of rules using various variables, including Request Header Names, Request Cookie Names, Request Arg Names, Request Post Arg Names, Request JSON Arg Names, and Request IP Address.

Azure Front Door Standard and Premium support Bring Your Own Certificates (BYOC) based domain ownership validation (preview)

Azure Front Door Standard and Premium now support Bring Your Own Certificates (BYOC) based domain ownership validation. With this feature, Azure Front Door can automatically approve domain ownership if the Certificate Name (CN) or Subject Alternative Name (SAN) of the provided certificate matches the custom domain. This reduces the steps and efforts required to prove domain ownership, streamlining the Dev-Ops experience. For domains created before this feature’s support and whose validation status is not yet approved, users will need to trigger the auto-approval of domain ownership validation manually.


Azure Premium SSD v2 Disk Storage now available in multiple regions

Azure Premium SSD v2 Disk Storage is now generally available in the Australia East, France Central, Norway East, and UAE North regions. This expansion offers customers in these regions the opportunity to leverage the benefits of Azure Premium SSD v2 Disk Storage for their workloads. Azure Premium SSD v2 Disk Storage provides high-performance and low-latency disk support for virtual machines running I/O-intensive workloads. By utilizing this storage solution, users can expect consistent performance, enhanced durability, and availability.
