Environments

Talend recommends deploying a Development, Test/UAT and a Production environment in AWS. In the above architecture diagram, we show such a setup with 3 environments. The Test/UAT environment should be a replication of the Production environment. For organisations with many parallel projects and development teams, it may be necessary to have multiple Test and UAT environments to minimize dependency between teams when running UAT testing.

Each environment should be completely segregated from each other, except for the access to Nexus snapsots and releases repositories. In certain scenarios, it is possible to have 1 releases repository for Test/UAT environment and 1 releases repository for Production environment. In this case, we can control access to the Nexus from the Test/UAT and Production environment through firewall access.
