This article contains a brief squeeze from my own experience and that of my colleagues, with whom I had been fighting incidents day and night. And many incidents would never have occurred if all these microservices that we love so much were written at least a little more carefully.
Unfortunately, some programmers seriously believe that a Dockerfile with any team at all inside is a microservice in itself and can be deployed even now. Dockers are running — money are incoming. This approach turns into problems starting from performance degradation, inability to debug, service failures and ending in a nightmare called Data Inconsistency.
If you feel that the time has come to launch one more app in Kubernetes / ECS / whatever, then I have something to object to.
