Provide a validated architecture blueprint for HA&DR deployment of a Nuxeo Cluster

Context

Nuxeo deployment architecture has become increasingly complex and architects working with Nuxeo Platform are asking for good practices and references architecture that can help them :

• define what technical components should be used
• define how these components should be deployed and linked together

Requirements

Automated testing

We want the target architecture to automatically tested against expected HA/DRP requirements, so that:

• we can validate non-regression
• we can adjust requirements
• we can adapt technical components

The goal is to have a living HA/DRP architecture.

Not just Documentation

Having documentation is a good step, but:

• maintaining the deployment & test documentation is hard and error prone
• having a big document does not mean people will be able to easily leverage it

So, rather than a document, the outcome of this tasks should be a set of artifacts that can be maintained separately and adapted to the customer use case:

• deployment diagrams
  • sometimes a good diagram is worth several pages of text
• deployment templates for the whole cluster with all components
  • we want the whole cluster to be deployed in 1 click
• test scenarios & scripts to validate the HA/DRP
  • something that can be used as a base to build custom tests
