## ownCloud Infinite Scale

Welcome to oCIS! We develop a modern file-sync and share plattform, based on our knowledge and experience with the PHP ownCloud server project.

### oCIS Server

The oCIS server implementation follows go-lang best practices and is based on the [go-micro](https://go-micro.dev/) framework and [REVA](https://reva.link/). We love and stick to [12 Factor](https://12factor.net/). 
oCIS is a micro-service based server, which allows scale-out of individual services to meet your specific performance requirements.
We run a huge test suite, which was originated in ownCloud 10 and continues to grow.
