1. Bringing DevOps to the Database

DevOps is a hot topic in today’s software development world. However most of the knowledge and experience with DevOps is based around application software and ignores the database. We will examine how the concepts and principles of DevOps can be applied to database development by looking at both automated comparison analysis as well as migration script management. Automated building, testing, and deployment of database changes will be shown.

4. What is DevOps? Grew out of the Agile movement
Velocity ‘09 – 10+ Deploys Per Day: Dev and Ops Cooperation at Flickr
Is not Agile (or Scrum or Lean or Kanban)
Is an amalgamation of various ideas and principles that describe how to better build software.

5. The Three Ways Principles underlying DevOps from Gene Kim
Systems Thinking
Amplify Feedback Loops
Culture of Experimentation and Learning

6. What is DevOps?
“DevOps is the union of people, process, and products to enable continuous delivery of value to our end users.” - Donovan Brown

7. Seven Key DevOps Practices
Configuration Management
Release Management
Continuous Integration
Continuous Deployment
Infrastructure as Code
Test Automation
Application Performance Monitoring

8. Seven Key DevOps Habits
Team Autonomy and Enterprise Alignment
Rigorous Management of Technical Debt
Focus on Flow of Customer Value
Hypothesis Driven Development
Evidence Gathered in Production
Live Site Culture
Manage Infrastructure as a Flexible Resource

9. DevOps in Practice Automation Testing
Continuous Integration
Continuous Delivery
Testing
Should be automated
Measurement and Tracking/Auditing
Logging in the application/database
Monitoring and baselining
Communication
Transparency
Sharing

15. Evolving Database Development
Version Control
Options for database DDL and DML
Scripting – SMO in SQL Server
Third Party Tools
File | Save
VCS Organization
Can be same repo or separate repo
Keep code separated

16. Demo
Store database code in a VCS

17. Database Continuous Integration
Use a Build Server
TFS Build, Bamboo, Team City, Cruise Control, Jenkins, whatever
Database Build
Pull code from VCS
Execute code (in order) on a database
Database Testing
Use a framework (next slide)
Publish
Generate an Upgrade Script for an existing database (coming soon)

18. Database Testing For SQL Server
tSQLt
Microsoft Unit Testing Projects
DBUnit
TSQLUnit
Custom scripted tests
* For best results, use curated test data

19. Demo
Implement Continuous Integration

20. Generate the Update Script
For code (stored procedures, functions, views, modules, etc.)
Take latest version from VCS
For tables
Use Comparison or migration scripts to make changes.
Tools
Comparison tools (SQL Compare, etc)
Migration Tools (ReadyRoll, FlywayDB, Liquibase, etc)

21. Deploy the Code Use a consistent process
Use automation where you can, use manual steps (documented) where you cannot
Slowly and continuously improve the process
Use a Release Management Server
Octopus Deploy
TFS
Bamboo

22. Release Issues Rollback Environment Data
For code (views, procs, functions) – Deploy the previous version
For tables – Need custom code
In general, I am a fan of dark deploys and roll forward
Environment Data
Data that varies by environment (queue names, security, etc)
Script and deploy with deploy once scripts
Use tokens where possible and store config data in the environment

23. Demo
Release to Downstream Environments

24. Summary Understand and implement the DevOps principles
Systems Thinking
Feedback Loops
Experimentation and Learning
Treat the database like application code
Build the exceptions into your process
Adapt to your environment
Do more of what works
Do less of what doesn’t
