After we have written the code and compile it, the next step is to build and deploy it somewhere. We can go two ways here: build many times the code, deploy it many times build once the code, deploy it many times Build many This is the way many of you are familiar with, as… Continue reading Build once vs build many

Firewall. Trust. Session. Tokens. We need to secure our applications and we need to secure our containers. Securing applications We can build a SSO… Continue reading Securing microservices

You don't need to write getters and setters for your class members! Suddenly it's enough to have @Getter @Setter… Continue reading Project Lombok
In a microservice environment it's hard to trace errors and logs, as we have lots of moving components. We could go into each service and read the logs, then aggregate them and finally with lots of patience try to understand what is happening. But we should not do this, we have alternatives. One of them… Continue reading Log tracing with Sleuth and Zipkin
