Azure Container Apps – a serverless container service for running modern apps at scale
Nowadays companies use cloud-native software development with microservice architecture to deliver value in a modern way to their customers. To run their microservices many of them are relying on container orchestration tools like Kubernetes. But these tools require infrastructure management which increases the effort to deliver and operate applications. This brings us to Azure Container Apps, a service presented during Microsoft Ignite 2021.
Azure Container Apps helps to run microservices and containerized applications on a fully-managed serverless service. Common scenarios of Azure Container Apps include:
- Hosting API endpoints
- Runnning background processing applications
- Scaling event-driven processing
- Deploying microservices
Azure Container Apps are backed by the open-source and cloud-native ecosystem:
- Containers are deployed to an abstracted Azure Kubernetes Service
- Scaling is managed by KEDA, an event-driven autoscaling project
- Microservices are exposed via Envoy
- State-of-the-art cloud-native development with Dapr integrated by default

General availability: Event Hubs Premium
Azure Event Hubs is a publish-subscribe service that can ingest millions of events per second. Those events can then be streamed to multiple configurable consumers. The service is highly scalable and lets you process and analyze a mass amount of data produced by your connected devices and applications. Once Event Hubs has collected the data, you can retrieve, transform, and store them. You can improve your Event Hub performance further by using the Premium level SKU which is now out of preview and generally available. This service is especially worth having a look at if you require high throughput, low latency, isolation, and more predictability.
The Azure Event Hub Premium has the following characteristics:
- Isolated CPU and memory level for each workload
- Purchasable 1,2,4,8 or 16 resource container (Processing Units with ~5-10 MB/s ingress and ~10-20 MB/s egress) for each Event Hub Premium namespace
- No Throttling limits for data streaming scenarios
- two-tier, native-code log storage engine that provides far more predictable and much lower ingestion and end-to-end latencies
- Supports availability zones with triple replicated events
.NET 6.0 for Azure Functions, Azure Web Apps and Azure Static Web Apps is now available
.NET 6 provides a high increase in performance which leads to reduced costs for hosted Cloud Services in Azure. .NET 6 will be supported for 3 years. It is the first release that natively supports Apple Silicon (Arm64) and has also been improved for Windows Arm64. It deploys .NET 6.0 Blazor WebAssembly apps automatically, including those that use advanced .NET 6.0 features. For backend APIs, you can build and deploy .NET 6.0 Azure Functions with your static web apps. Both in-process and isolated .NET 6.0 function apps are supported.

Azure SQL—Maintenance windows now in preview
Applying to Azure SQL Database and SQL Managed Instances, the Maintenance window feature is now in preview and free of charge making maintenance events more predictable. The maintenance window is intended for production workloads that are not resilient to database or instance reconfigurations and cannot absorb short connection interruptions caused by planned maintenance events. You can choose a dedicated maintenance window defining the time outside of business hours. Maintenance is blocked by default from 8 AM to 5 PM at the local time zone.
Now two additional windows for Azure SQL can be chosen:
- Weekday window: 10:00 PM to 6:00 AM local time, Monday – Thursday
- Weekend window: 10:00 PM to 6:00 AM local time, Friday – Sunday
Configuring maintenance window is a long-running asynchronous operation, similar to changing the service tier of the Azure SQL resource. With the help of notification, it is possible to get informed ahead of any update event to your services.
Additional Updates for Azure SQL
Azure SQL got a lot of updates in November which are worth checking out:
- the storage limit for SQL Managed Instances General Purpose is raised to 16TB (check here)
- the backup frequency for differential backups can be changed from 12 to 24 hours
- SQL Managed instances can now be moved from one subnet to another online. You can read more on the blog here
