Why opting for Postgres and not just stay with Oracle?

• Introduction of OPENSTACK as our (private) cloud platform

• Oracle is not compatible with containers (Openshift)

• The Oracle license cost and inflexible licensing model

• Oracle’s ‘feature stress’: extra cost options are easily enabled by accident

Also…

• Do we need thi$$$

• If thi$ can do the same?

Isabel started a search for

• a robust relational database

• suitable for the applications now serviced by Oracle

• with a flexible licensing model, suited for VM

• and 7 x 24 customer support (via an external partner)

Candidate RDBM’s

• DB2

• SQLServer

• MySQL

• Questions

We were looking for support

•From an external partner

•Based only on effectively used virtual CPU’s

We opted for EDB Postgres because:

• Postgres Plus Advanced Server (PPAS)

• An Oracle compatible version of Postgres

• 85% of Oracle’s functionality (= 100% of Isabel’s needs)

• < 10 % TCO compared to Oracle

EDB – added value

•Productivity tools:

• Postgres Enterprise Manager

• Backup tool

• Failover manager

• Replication server

• Migration toolkit

Proofs of Concept

• EPCM (a small eBanking application) – Migration successful

• Risc Adaptable Access Control (RAdAC) – Migration OK, but hard to test

• Web Onboarding application (Service Hub) – works!

What we did next:

• Included Postgres in our DB portfolio

• Designated Postgres as the preferred DB for new initiatives

• Migrated ServiceHub application from Oracle to Postgres

• Decided to migrate ZoomIT from Oracle to Postgres (1st quarter 2018)

What Postgres lacks

• SQL plan management (SPM)

• Flash back database

• Database recycle bin

What EDB does well

• EDB support: • average resolution time is less than 1 hour• You can actually mail and call the support team

• EDB migration tool kit• Converts Oracle schema’s and even whole databases almost flawlessly• Highly configurable

• Oracle compatibility layer• Most existing application only need very minor code changes

• EBS licenses are ‘ALL IN’
