Open Source wins in the RDBMS space
By 2022, more than 70% of new in-house applications will be developed on an OSDBMS or
OSDBMS-based dbPaaS, and 50% of existing proprietary RDBMS instances will have been
converted or be in process of converting.
By 2022, more than 60% of all global organizations will formalize their management of internal skills
and standards related to OSDBMS to enable better use of open source in production.

Eat the elephant - one byte at a time
Temptation:
● Go for major impact
● Address the worst legacy problem first
Recipe for success:
● Tier your applications
● Develop reference architectures
● Understand your maturity
● Find the balance between feasible and meaningful

Reference Architectures
● CPU, Memory, Storage
● Local, metro, geo-distributed
● Replicas for redundancy, read-
scalability or both
● Streaming replication, logical
replication or both?
● Connection pooling, query
routing, or both?
● SLA, RPO, RTO, GRO

Emerging
• Getting started with PostgreSQL
• Often for a single project
• For test/dev apps
Strategic
• PostgreSQL considered a “standard”
• Many production apps incl. tier 1
• Concerns for scalability, HA, and automation
Expanding
• Increasingly for production apps
• Tools and automation important
• Worries about database security

Collaboration and evangelizing
Problem Evangelizing Enablement
Successful open source adoption benefits from organizational change
● DBA teams and
development teams are
often at arms length
● “The infrastructure is
ready, but nobody uses it”
● “We would build on
Postgres, but the DBAs
can’t handle it”
● Create a bottom-up
innovation movement
● Informal discussions,
lunch & learns,
hackathons, meetups
● Create DevOps culture -
break down the walls
between developers
and DBAs
● Make sure DBAs are
ready to support
production
● Consider Remote DBA
Services
● Invest in automation to
be responsive

21. Automation and
standardization
• Open source == agility
• Agility == speed and scale
• There is no scalability without
automation
• Automation requires
standardization

Postgres Deployment Automation
Technology Decision
Choices
• Terraform
• CloudFormation
• Ansible
• Chef
• Puppet
• Salt
• Configuration Management Vs Provisioning
• Procedural Vs Declarative
• With local install or not
• Mutable Infrastructure Vs Immutable
Infrastructure
• Agent Vs Agentless
Factors to Consider
