Picking a specific database technology is not done overnight. It is not a decision that is taken lightly. You will most probably select a database technology for a long time, as the dogma of database agnostic has proven not to exist. Switching database technology is even more challenging. To even consider switching the workhorse under you prized, mission critical applications, the switch would have to bring serious advantages. Many years, if not decades, have been invested in building and testing everything, why change? I have invested nearly a quarter of a century working with Oracle technology, yet I made a switch. In this talk I want to take you through some of the considerations of this change and perhaps show that picking Postgres over Oracle makes sense…
11. WHY - SIDE STEP
CLOSE VERSUS OPEN
▸ Develop solutions to sell
▸ Primary goal is to do business
▸ Develop solutions to solve a problem
▸ Primary goal is to solve a problem
12. WHY - SIDE STEP
CLOSE VERSUS OPEN
▸ Open software shows the math, not just the answer
▸ Not reverse engineering, just a good read
▸ Allows for tailoring of solutions
24. PICKED - SIDE STEP
CORE INFRASTRUCTURE
▸ High availability
▸ RAC or ADG vs. streaming replication & load balancing
▸ Disaster recovery
▸ RMAN vs. BART
▸ Integration
▸ Golden Gate vs. logical replication or FDW
32. POSTGRES - SIDE STEP
COMMUNITY OPEN SOURCE
▸ Closing presentation by Bruce Momjian - “Will Postgres Live Forever?”
Proprietary Software Life Cycle
versus
Open Source Software Life Cycle
40. OVER - SIDE STEP
OPEN OR CLOSED
▸ “Black Box” approach can also be really tricky
▸ Not just with traditional vendors
▸ Amazon RDS vs. regular PostgreSQL
51. LESSONS LEARNED
DON’T BE AFRAID
▸You are not alone
▸Technically it’s never an issue
▸Not much fresh wine
52. LESSONS LEARNED
SMALL TO BIG
▸They all state it
▸Video recorder to conglomerate bank
▸We don’t need promises
53. LESSONS LEARNED
THERE ARE MORE WAYS
▸But when it comes to databases
▸That truly need to do something
▸Postgres could just be
▸Your best bet for the future!
