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 21st October 2024, grouped by Azure service.

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

Azure services with highlighted updates this week:

• Azure Backup
• Azure Storage
• Compute
• FinOps
• Redis

Azure Backup

• GRS and Cross-Region Restore support for Azure VMs using Premium SSD v2 and Ultra Disk in Azure Backup (GA) : Definite improvement for DR resilience if you’re using Premium SSD v2 or Ultra disks with your VMs. GRS vaults and Cross-Region Restore are currently supported in the following regions for machines using Premium SSDv2 Disks: Southeast Asia, East Asia, North Europe, West Europe, East US, West US, and West US 3. Coming to other regions in later months (not sure this really counts as ‘Generally Available’ yet, if I’m being honest!).

Summary of Azure snippets for the week commencing 30th September 2024, grouped by Azure service. Almost back to normal posting cadence :-)

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

Azure services with highlighted updates this week:

• Application Gateway
• Azure Backup
• Azure Cache for Redis
• Azure DB for PostgreSQL
• Azure Kubernetes Service
• Infrastructure as Code
• Network Security Groups
• Virtual Network Manager

Application Gateway

• Azure Application Gateway support for TLS 1.0 and TLS 1.1 will end by 31 August 2025 (RET) : All connections (frontend and backend) to Application Gateway must use Transport Layer Security (TLS) 1.2 or later, as support for TLS 1.0 and 1.1 on Azure Application Gateway will be discontinued starting 31st August 2025.

Azure Backup

• Azure Business Continuity Center (Public Preview) : Centralised management platform for backup and disaster recovery of Azure resources. Will be replacing the Backup Center, which I think we can probably safely regard as deprecated from this point forward. Supports resources in all regions and a variety of sources and scenarios. (No idea why the title of the page on Azure Updates says Generally Available when it’s clearly still in preview :-)

Azure Cache for Redis

• Smaller Enterprise tier cache instance for Azure Cache for Redis (GA) : Following the very pricy Large Enterprise instances, there’s now a more cost-effective smaller one. Runs on burstables and recommended for dev/test only, but very much cheaper than the other Enterprise tiers.

Azure DB for PostgreSQL

• Online migration from Azure Database for PostgreSQL - Single Server to Flexible Server (GA) : Now out of preview, minimal downtime migration for PostgreSQL Single Server instances.

Azure Kubernetes Service

• gRPC and frontend mTLS now available for Application Gateway for Containers (GA) : Application Gateway for Containers now supports gRPC and frontend mutual authentication (mTLS). With both frontend and backend mutual authentication, end-to-end mutual authentication is now possible. This fills what I considered a fairly significant gap in the functionality of App Gateway for Containers, and brings it more in line with other ingress/gateway solutions.
• Long-term support for Kubernetes version 1.27 and 1.30 in AKS (GA) : K8s v1.30 has now joined 1.27 on the AKS LTS list.
• Open Service Mesh add-on for AKS will be retired on September 30, 2027 (RET) : Istio is (currently) the only option for a ’native’ AKS service mesh add-on going forward.
• Virtual machines node pools support in AKS (Public Preview) : With virtual machines node pools, Azure Kubernetes Service directly manages the provisioning and bootstrapping of every single node. (For Virtual Machine Scale Sets node pools, AKS manages the model of the Virtual Machine Scale Sets and uses it to achieve consistency across all nodes in the node pool.) Virtual Machines node pools allow the capability to add multiple VM SKUs of a similar family (e.g. different D-series SKUs) to a single node pool.
• Latest AKS release (GA) : Some ongoing updates from the last release, plus 1.30 in LTS (see above), and AKS patch versions 1.28.13, 1.29.8, 1.30.4 are now available

Infrastructure as Code

• Transition from Helm Repositories to OCI Artifacts for Storing Helm Charts (RET) : Starting March 30th, 2025, Azure Container Registry will no longer support Helm v2. Therefore, the legacy “Helm repositories” functionality will also be retired. After this date, Azure Container Registry will only support storing Helm charts as Open Container Initiative (OCI) Artifacts. Get your migration sorted out where needed - any Helm charts not stored as OCI Artifacts in ACR will be deleted after 30th March 2025!

Network Security Groups

• Network security group flow logs in Azure Network Watcher will be retired (RET) : Flow logs to be retired on 30/9/27, but you won’t be able to create new ones from 30/6/25. Migration path is to virtual network flow logs, and a migration process is available.

Virtual Network Manager

• Azure Virtual Network Monitoring IP address management (Public Preview) : This feature (part of Virtual Network Manager) is designed to streamline and optimise your IP address management, providing you with greater control and efficiency. Tracking IP address use in VNets and subnets to avoid clashes can be tricky in Azure, and if you’re using services such as Private Endpoints which can dynamically assign IP addresses, it gets even harder - something like this could be helpful and maybe remove the need for manual tracking of IPs. Preview available in UK South but not UK West.

And finally, goodbye to Azure Orbital Ground Station, which is being retired on 18th December 2024. Not my usual focus, but I couldn’t let it pass without a note!

Summary of Azure snippets for the week commencing 9th September 2024, grouped by Azure service. Back to regular posting following holidays - though only a couple of updates this time around.

No monthly summary for August as there was only one other post before this one that wasn’t covered by July’s summary.

GA = Generally Available
Public/Private Preview = as stated :-)

Azure services with highlighted updates this week:

• API Management
• Azure Cache for Redis

API Management

• Workspaces in Azure API Management (GA) : Workspaces enable organizations to manage APIs more productively, securely, and reliably using a federated approach. They function like ‘folders’ within an APIM instance, with access controlled via RBAC. A provisioning enhancement to the developer portal, which can maintain overarching policies, logs, etc. Blog post and documentation.

Azure Cache for Redis

• Larger Enterprise tier cache instances for Azure Cache for Redis (GA) : Large amounts of CPU and memory for the most demanding applications. Very powerful and significantly pricy!

Microsoft Build took place this week, so lots of announcements - unsurprisingly, a strong focus on Copilot and AI, though there were some other technologies covered as well. Have a look at the Build 2024 Book of News for all the new stuff announced.
