Availability Zone

It is a best practice from AWS to deploy the platform in 2 availability zones at a minimum for Production environments. The more availability zones you use, the better availability you will have for the production environment.

In the above architecture, we deploy Talend Administration Center in EC2 instances in 2 availability zones. In Production, depending on the critical nature of the platform, we can have 1 Talend Administration Center running or both Talend Administration Center s running. We can also configure an AutoScaling group in AWS so that a second Talend Administration Center is started if the first one is not available anymore.

We also have Job Servers in 2 availability zones, for greater platform availability and ability to execute more jobs.
