Stop paying for Larry’s boat!

PostgreSQL is a fully-featured, enterprise-grade and open source database, named two years in a row database of the year! And it’s also the best candidate to migrate off of Oracle, supporting very advanced SQL, easy administration and pl/pgsql, a replacement for Oracle’s PL/SQL. Stop spending hundreds of thousands or millions of $ on database licenses and reinvest them in your team, infrastructure and software.

Join this half-day tutorial to learn the best practices, tricks and tools to perform a successful Oracle to PostgreSQL migration. Learn from the team that performed 150M users Blackberry migration to PostgreSQL on GCP with near-zero downtime, and the key author behind orafce, a set of Oracle compatible functions on top of PostgreSQL.

DBMS inside container is a nightmare for DBA. I will describe how we use containerized Postgres in Juno. What problems we faced with and how did we solve them.

• Migration of the standard 1C cluster to MPI environment - "machine to machine migration of services".
• PostgreSQL migration to GPU powered machine.
