Service Mesh is the future of application connectivity.
It delivers immediate value to any architecture by increasing our application traffic’s security, reliability, and observability.
It abstracts the underlying network details and provides discovery, routing, and a variety of other functionality.
But what is in it for Java/JVM developers? Don’t we already have all of this functionality in the frameworks?
In this service mesh presentation, Viktor will show you how easy it is to get started (in Kubernetes) - how to install a control plane, deploy a Java demo application (spring boot, micronaut), enable traffic policies, and touch on observability - all this without convoluting allocation with different frameworks or custom code.
