Summary of Azure snippets for the week commencing 26th May 2025, grouped by Azure service.

With Build taking place last week, a lot of announcements have dropped as usual, so this is a fairly big post. The Build 2025 Book of News has all the details of announcements from there. Plenty of AI focus as usual - I’ll cover some of the stuff that isn’t AI-related here :-)

For all the updates on Azure platform resources and products - Azure updates from Microsoft

Summary of Azure snippets for the week commencing 2nd December 2024, grouped by Azure service.

It’s been a little while since I posted, and this one is a bit of a bumper one with MS Ignite having finished recently - a lot of Azure updates have dropped, along with other products. AI is unsurprisingly a big theme once again :-) Check out the Ignite 2024 Book of News for all the details.

Summary of Azure snippets for the week commencing 28th October 2024, grouped by Azure service.

GA = Generally Available
Public/Private Preview = as stated
RET = Service retirement

Azure services with highlighted updates this week:

• API Center
• Azure Storage
• Compute
• Infrastructure as Code

API Center

• API Management & API Center Synchronization (Public Preview) : Link an APIM instance to API Center to sync the API inventory and keep it continuously up to date.

Azure Storage

• Live Resize for Azure Premium SSD v2 and Ultra Disks (GA) : Increase your Premium SSD v2 and Ultra disks’ storage capacity without stopping your VM. Some limitations to this capability and unsupported regions, check the docs carefully.

Compute

• Azure Cobalt 100-based Virtual Machines (GA) : General purpose Dpsv6-series and Dplsv6-series and memory-optimized Epsv6-series VM series. These VMs run on Microsoft’s first 64-bit Arm-based Azure Cobalt 100 CPU, which has been fully designed in-house. Up to 50% better price performance than previous generation Arm-based VMs. Region availability expanding through the rest of 2024, UK South is coming soon.
  • Arm newsroom post

Infrastructure as Code

• AzAPI version 2.0 released (GA) : The AzAPI provider is designed to expedite the integration of new Azure services with HashiCorp Terraform. It functions as a lightweight layer atop the Azure ARM REST APIs, and is a first class provider experience along with the AzureRM provider. Azure resources that might not yet be or may never be supported in AzureRM can be accessed by this provider, including private/public preview services and features. v2.0 now fully supports HCL (no more JSON) among other updates. Both Microsoft and Hashicorp have blog posts comparing AzureRM and AzAPI and scenarios where you might choose one over the other (they’re mostly the same post but with some additional stuff in each :-) There is also now a tool (aztfmigrate) that lets you migrate resources between the two providers.

Azure services with highlighted updates this week:

• API Center
• Azure Kubernetes Service
• Azure Resource Manager
• Azure Site Recovery
• Azure SQL

API Center

• Azure API Center Extension for VS Code (GA) : Build, discover, try, and consume APIs in your API center

Azure Kubernetes Service

• Advanced Container Networking Services for AKS (Public Preview) : A new suite of services bringing advanced network monitoring and diagnostics to AKS clusters. Currently includes only Advanced Network Observability as its inaugural and foundational feature - more are planned.
  • Advanced Network Observability is based on Hubble (itself based on Cilium, but both Cilium (with Kubernetes 1.29) and non-Cilium AKS data planes are supported). It uses Grafana and Prometheus for visualisation (Azure-managed or bring your own), and Retina on non-Cilium nodes (presumably as the eBPF ‘bridge’). It also supports all Azure CNI variants including kubenet.
• Open Service Mesh deprecation : I noticed when looking through the AKS LTS docs that Open Service Mesh was noted as being deprecated. Looks like the CNCF are retiring it and Istio is currently the only option for an AKS-supported service mesh.

Azure Resource Manager

• Deployment Stacks (GA) : Deployment stacks are an Azure resource type which provide a means of managing a collection of Azure resources as a single unit. They are designed to work primarily with Bicep, and are essentially a replacement for Blueprints (which never made it out of preview).

Azure Site Recovery

• Reporting Capabilities for Azure Site Recovery (Preview) : Full-featured and customisable reports based on Azure Monitor logs. Available via Business Continuity Center, Recovery Services Vault and Backup Center
  • Blog post
  • Documentation
• Monitoring improvements for ASR : An improved alerting solution for Azure Site Recovery, including default alerts via Azure Monitor. Brings ASR alerting into the Azure Monitor alerts space for a more consistent experience.
  • Blog post
  • Documentation

Azure SQL

• Availability portal metric (Public Preview) : Monitor SLA-compliant availability of Azure SQL databases in the Azure portal. Supported for DTU and vCore-based DBs at all service tiers, and for single DBs and elastic pools.
• Update policy for Managed Instances (GA) : Choose the speed of updates for new SQL engine features for your managed instance:
  • Always up to date (engine features deployed as soon as they are released in Azure, without waiting for the next major release of SQL Server) or SQL Server 2022 (follows the mainstream servicing lifecycle of SQL Server 2022, with no new SQL engine features deployed until SQL Server vNext is released).
  • The former brings new functionality faster but keeps the database format changing (so e.g. restores or replication to other (‘on-premises’) SQL Server instances might break); latter keeps the SQL engine at 2022 (you still get Azure SQL platform updates) and maintains the database compatibility level, but no new features until SQL vNext.
  • Can change from SQL 2022 policy to Always up to date, but cannot go the other way as DB format can’t be downgraded.

Provides (among other features): cataloguing and inventory of APIs (including from APIM), governance and design rule enforcement, API Analysis for consistency and compliance, and a Visual Studio Code extension for an enhanced developer experience. More full featured than I thought - is this the future of the APIM developer portal?
