New Features For Spring Cloud Kubernetes In Spring Cloud 2021.0.0-M3

When we got the results back from the latest State Of Spring survey, 67% of you said you would like to see better support for service discovery and configuration management on Kubernetes.

With the release of Spring Cloud 2021.0.0-M3, we are taking a big step forward to addressing both of these concerns!

Spring Cloud Kubernetes has offered a DiscoveryClient implementation since its inception. However, the implementation required the application to have permissions to use the Kubernetes API server. This proved to be a major barrier for many Spring Cloud user’s, as Kubernetes administrators were hesitant to give apps permissions to make API requests to the Kubernetes API server.

Spot every Spring Boot application issue on the spot using AppDynamics!

Today, we are excited to announce the integration of AppDynamics in the Azure Spring Cloud for full stack observability.

Over the past 20 months, we worked with many enterprise customers to learn about the scenarios they face. Many of these customers have thousands of Spring Boot applications running in on-premises data centers. As they migrate these applications to the cloud, they need to instrument them for application performance monitoring (APM) using solutions their developers are familiar with and have been using for years. In addition, they must ensure continuity for desktop and mobile applications that are already pre-instrumented for end-to-end monitoring using agents like AppDynamics, which automatically discovers and maps all applications, microservices, and infrastructure as well as any dependencies in dynamic hybrid, multi-cloud environments. With the integration of AppDynamics in Azure Spring Cloud, you can continue your journey and easily instrument your Spring Boot applications with AppDynamics.
