The distributed services (or, microservices) debugging is a pain. If you've ever tried to debug more than 2 services working together, you can't forget all the suffering you went through.

Squash - is quite promising project that allows you to debug microservices from your IDE. Yes, you understand it right: you just set breakpoints in your code and debug running distrubuted services as usually, line by line. At the moment it works only with VS Code.

If you have a dozens or even hundreds of microservices and all of them expose their APIs to the rest of the world, you often need to manage the same things for every service separately, such as authentication/authorization, security checks, load balancing and etc... In this case an API Gateway could be useful, becuase it builds sort of "façade" for your APIs and allows to manage all APIs in one place. Here are few open source solutions:

• Kong, has 12,3k stars on GitHub. Build in Lua language on top of Nginx. Provides a lot of ready plugins for security and Auth, rate-limit, caching, logging and etc...
• Tyk, has 2,4k stars on GitHub. Build on Go. Provides many features out-of-the-box, such as web Dashboard, with monitoring, API documentation, Mocks for testing, notifications and many more...
