This is a list of web resources on technologies tied (directly or proximitly) with architecture and design of microservices.
Total more than 100 resources aggregated
I chose mostly those technologies created on the basis of Java/Scala, but this is a sort of personal choice - microservices, as well as all related services, can be written in any language.
You can extend this list - see the Contribution section.
