The microservice architecture approach has been very popular in the recent years. There is a big hype around it and a large swarm of open source tools to facilitate each aspect of this architecture. The purpose of this talk is to identify the main components of a microservice architecture. After that we compare different open source tools that fits into each area. At the end we’ll have a good understanding what a microservice architecture based on OSS looks like.

● Success rate
● Error rate
● Response time - p95, p99
● RPS
● Queue size
● Memory usage
● Disk space usage
● ...
