Microsoft just dropped a massive set of Azure Kubernetes Service (AKS) updates for August 2025, and honestly, this release feels like they went on a feature spree. Some updates are General Availability (GA)—ready for production right now—while others are in Preview so we can kick the tires before they’re finalized.

Here’s my breakdown, in plain English, of what’s new, what’s exciting, and why I think these changes matter for anyone running AKS in production (or planning to).

🚀 Preview Features — Stuff I’m Already Testing

1. AKS Agentic CLI
Think of this as an AI-powered sidekick for az aks. The new agent mode in the Azure CLI can guide you through cluster management tasks, making it less “hunt through docs” and more “just tell me what you need, and I’ll make it happen.”

2. Managed Namespaces
Finally, namespaces with governance built in. I love this because it gives teams a clean way to enforce limits and policies per namespace without extra YAML gymnastics.

3. AKS Virtual Network Verifier
Network debugging without tears. This tool checks outbound connectivity from inside your cluster—perfect for diagnosing weird firewall or NSG issues.

4. Multiple Standard Load Balancers per Cluster
One SLB isn’t always enough. This lets you assign different SLBs to different workloads or node pools—useful for isolation or handling different traffic profiles.

5. Managed Prometheus Quota Boost via API
No more running into ingestion limits mid-metrics spike. You can now bump your Azure Managed Prometheus ingestion quota through the ARM API.

6. LocalDNS for AKS
DNS lookups get faster by keeping a proxy right on each node. This one’s a quiet performance win, especially for big clusters.

7. MCP Server (Model Context Protocol)
If you’re integrating AI into your cluster workflows, this is a huge deal. MCP is an open protocol that makes orchestrating cluster actions from AI agents far simpler.

8. Azure Bastion + AKS Integration
Securely hop into private clusters without punching a hole in your control plane. I’m already imagining less hassle when working with locked-down environments.

9. Deployment Safeguards
Think of this as a smart bouncer for your deployments. It checks for bad patterns and stops you before you push something that could break your cluster.

10. Azure Files NFS Encryption in Transit
For workloads using NFS v4.1, you can now encrypt that data while it’s moving—finally closing that security gap.

11. Disable HTTP Proxy in AKS
Control your own egress path by opting out of AKS’s built-in HTTP proxying. Niche, but powerful for custom networking setups.

✅ GA Features — Ready for Production Today

1. Control Plane Improvements
AKS has optimized the API server memory usage by using streaming encoding for big LIST calls. Translation: less overhead, faster responses, happier control planes.

2. AKS Security Dashboard
One place to see vulnerabilities, misconfigurations, and runtime risks across your cluster. This is something I expect security teams will live in daily.

3. Static Public Prefix for Egress Gateway
Predictable outbound IPs are no longer a headache. Perfect for firewall whitelists and compliance.

4. Confidential VMs on Ubuntu 24.04
Confidential computing for your sensitive workloads is now GA—backed by Ubuntu 24.04. This is a huge win for regulated industries.

💡 My Thoughts

This update feels balanced—Microsoft is giving us experimental features like AI-driven CLI and managed namespaces to try out, while shipping serious production-ready improvements in performance, networking predictability, and security.

Personally, I’m most excited about LocalDNS for the performance gains and Bastion integration for secure remote cluster access. But the control plane improvements and security dashboard are going to save real money and headaches for anyone running big clusters.

If you’re on AKS today, I’d suggest:

• Test the Preview features in a dev environment—especially the AI CLI and managed namespaces.
• Adopt the GA security and networking updates as soon as you can.
