I use EDB Postgres Advanced Server for production workloads, but the solution also works well for development. Developers can have local versions, and it's also the same database you use in production.

As a replacement for Oracle RAC where there's need:

• More than four servers
• Dynamically deployable servers
• Split access between the transnational and reporting on the same data store.

We have around 170 data centers around the world. We deploy our projects based on the use case and requirements and the projects can vary. Most of those deployments for Postgres are for engineering purposes.

I am responsible for our database products. We use these solutions only on-premises because our government has placed restrictions on our type of organization. The EDB Postgress Advanced Server is something we use for simple database projects on linux.
