Architecture
===============

The architecture of VVP based on micro-services. Each element has
dedicated container.
VVP uses rocket and kubernetes to manage the VVP system.
There is a devkit component which allows you to render and deploy VVP.
It's render and deploy the rockets with kuberenetes management (via quay.io).

We store files on Ceph distributed storage system that includes 'RADOS Gateway'
which allows us to store files in AWS S3 based API (buckets etc..).
