Managing failure modes in microservice architectures

About me and our project

I’m Denis, a Russian moved to the Netherlands to help building Jexia, a cloud hub providing a full-service serverless architecture.

With Jexia, a developer pays zero to eight euros per month to craft fully equipped applications. It would be awesome if you are able to test it yourself!
