6 Purpose of this presentation Explain why Isabel has chosen for PostgreSQL as it s primary RDBMS Why EDB Postgres?

7 Agenda Introduction Why not just stay with Oracle? Searching for a candidate RDBMS Postgres Comparing features Looking for support Total Cost of Ownership (TCO) Isabel s actions and decisions Advantages / disadvantages Questions

8 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

9 Also Do we need thi$$$ If thi$ can do the same?

11 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)

12 Candidate RDBM s DB2 SQLServer MySQL PostgreSQL

14 Winner: Postgres Postgres is open source Thus: no license fee But also, no support, except from the community

17 Required key features Core Database Features Oracle Postgres ACID transaction support Yes Yes Crash recovery Yes Yes Cost-based optimizer Yes Yes Data partitioning Yes Yes Data compression Yes Yes User-defined datatypes Yes Yes Multi-terabyte database capable Yes Yes High-speed, parallel data loader Yes Yes Memory/distributed caching option Yes Yes Connection pooling Yes Yes JSON support Yes Yes

19 We were looking for support From an external partner Based only on effectively used virtual CPU s

20 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

21 EDB added value Productivity tools: Postgres Enterprise Manager Backup tool Failover manager Replication server Migration toolkit

23 Oracle vs. EDB TCO Comparison on x86 License Fee Per Core Oracle Enterprise Edition (2 sockets/8 cores) (x86 processor) EDB PPAS (2 sockets/8 cores) (x86 processor) Database $47,500 included in subscription Partitioning $11,500 Included Data Guard $11,500 Included Diagnostics $5,000 Included Total License Fee per Core $75,500 included in subscription Total License Fee per Server (CapEx) (0.5 core factor) $302,000 $0 Annual support/subscription cost per core 22% of License Fee $1,750 per Core Annual Support/Maintenance per Server (OpEx) $66,440 $14,000 Total 3 Year License and Support Cost $501,320 $42,000 No CAPEX Annual OPEX 79 % 3 YR TCO cost 92 % reduction savings

25 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!

26 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 (1 st quarter 2018)

28 What Postgres lacks SQL plan management (SPM) Flash back database Database recycle bin

29 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
