The Power of Observability and DNS Tools in Azure Kubernetes Service (AKS)

When it comes to managing network performance and security within your Azure Kubernetes Service (AKS) clusters, observability and Domain Name System (DNS) tools play a crucial role. These tools provide real-time data on network performance, helping you identify and address performance issues early on. Additionally, visualization tools help you understand the interconnections between different services and how they interact with each other.

The DNS tools available in AKS work seamlessly with Azure networking, allowing you to deploy networking policies that control access to your services. By using domain names to filter access, you can easily manage which hosts have access to specific services, both inside and outside your AKS environment. This approach simplifies access control tables, making it easier for security operations (secops) engineers to identify and address any errors or risks.

For those already using Retina for observability, it’s important to note that switching to Cilium is necessary to leverage the networking tools in Advanced Container Network Services (ACNS). While ACNS is still in preview, it offers a range of new features that make it a compelling addition to your AKS infrastructure.

With a combination of security and platform tools, ACNS is poised to become an essential component of any Azure cloud-native environment. By embracing these tools, you can enhance the performance, security, and reliability of your AKS clusters, ultimately improving the overall efficiency of your cloud-native applications.
