Deployment
Continuous deployment is the Agile philosophy expanded to deployment.
Every change that passes the automated tests is deployed to production
automatically.
(tl;dr: deploy code in smaller chunks, more frequently)

4. #continuousdeployment
Why do Continuous Deployment?
- Ship features to users more quickly
- Experiment and validate assumptions more rapidly
- Be more responsive to unforeseen problems
- Minimize the risk of each deployment*
- Keeps your agile process honest:
- “But we are Agile! We use user stories and have sprints!”
- Many teams have agile process without agile technology
- CD requires both
*But be careful about “switching on” large features

5. #continuousdeployment
3 Criteria for Successful Continuous Deployment
Infrastructure
What tools do
you need?
Culture Testing
Do you have checks &
balances?
How comprehensive is
your testing?

6. #continuousdeployment
Criteria #1: Infrastructure Basics
Continuous
Integration
(CI) Servers
Version Control
Unit +
Integration
Testing
Monitoring

7. #continuousdeployment
Criteria #2: Culture of Collaboration
● Trust your team
● Remove red tape in the code review process
● Involve developers closely in production
operations
● Review pull requests (re: sanity checks)
83% of SaaS companies
with a high CD adoption
rate report that using a
collaboration platform
played a highly important
role in achieving CD. *

8. #continuousdeployment
Criteria #3: Test Continuously
Test as early & often as possible
● Unit tests
● UI tests (automated vs. manual)
Production monitoring + Rollbacks
Zenefits was able to scale their
customer base to 10,000+
without an in-house QA team
by supplementing their testing
automation suites with manual
testing.
