If a trading platform loads slowly or experiences errors, it will translate into loss of business, and losses can be extremely high, and the customer might end up switching to another competitor. In this context comes the Application Performance Management (APM)....

I. Introduction In this tutorial I will show you how to write a small Spring Boot CRUD application and how to deploy it on Kubernetes. Spring Boot is an innovative project that aims to make it easy to create Spring applications by simplifying the configuration and deployment actions through its convention over configuration based setup. Kubernetes (commonly referred to as “K8s”) is an open-source system for automating deployment, scaling and management of containerized applications that was originally designed by Google and now maintained by the Cloud Native Computing Foundation....
