In this presentation

Database release pipelineContinuous IntegrationDevelopment ProductionTesting

Goals

• Understand the patterns and practices for

automating database deployments.

• Learn about the advantages continuous integration

brings to a release pipeline.

• Understand the challenges databases present for

continuous delivery.

Continuous delivery – what it is and isn’t

Common misconception:

Continuous delivery = Continuous deployment

But in fact:Continuous delivery means making sure your database changes are always production-ready.

Four key stages of the deployment pipeline

CONTINUOUS INTEGRATION

AUTOMATED TESTING

AUTOMATED DEPLOYMENT

Get your database under control

• Use version control for all code (including tests)

• Commit early, commit often• Use tools

o If it’s hard, people don’t do it• Train people• Build often

SOURCECONTROL

Continuous Integration

• Requires• Code repository• Build automation

• Delivers• Functional testing• Delivery testing• Artifact generation

CONTINUOUS INTEGRATION:

FUNDAMENTALS

Database Deployments in CI

• Complete deployment• Fast• Partial build validation• Functional validation• No artifact

• Incremental deployment• Longer• Harder• Complete build validation• Generates artifact

Demo

Pre-production is a dry-run

• Staging matches production• As close as possible• Can use diff tool • Or backup and restore AUTOMATED

Wait…

Check for database drift

• Last-minute hotfix• Manual emergency fixes• Unknown changes

AUTOMATED DEPLOYMENT

Ready to go now?…

Plan for things to go wrong

…you need a rollback and recovery strategy

AUTOMATED DEPLOYMENT

Protection

• Backups• Snapshots• Rollback scripts• A/B or blue/green deployments• Roll forward scripts
