Tracing network transactions

Nowadays, with the advent of microservice architectures and modern container orchestration systems, it is very easy to build large distributed systems. It happens very often that distributed applications behave slow—not because the network is slow, but because there is too much communication between application components. Complex distributed systems can have tens or even hundreds of communicating services and microservices. Very often, those services are replicated across many computing nodes with various hardware characteristics. These services often communicate with multiple backing services through many middlewares and intermediate layers, like caching proxies and authentication servers. It's not a rare situation ...
