Worrying and Love the Process

As Developers we love
process
2
• TDD
• Code Review,
• Branching & Merging
• Pair programming
• …

Good process makes good
teams win

Bad process makes great
teams suck

Deployment/Delivery is 2nd
class citizen

“Unshipped Code is technical debt.
No benefits, only costs”

7
Hard to resolve
8
Not just technical problem
9
Customer Feedback
essential
10
late feedback, slow
improvement
11
Money not a barrier to entry
12
All about speed of innovation
13
Processes that helped
us at Codeship
14
Repository driven
infrastructure
15
Developer Automated Deployment
Push to production branch
Notify when ready
or problems
16
Full automation to focus on
development
17
Repo is one true source
18
• No Misunderstandings
• One last commit per Branch
• We live in our repos
19
Eventually consistent
infrastructure
20
You push to repo, eventually
infrastructure is up to date
21
Full system
automation
22
• Testing
• Deployment
• Metrics & Health Checks
• Validation
• Recovery
• Feedback and Notifications
23
Updating servers often risks
inconsistent server state
24
Rip out and replace
25
Stop thinking “single server”,
start thinking “part of a system”
26
Immutable
Infrastructure
27
Build new images for every
change
28
Test in Isolation
29
Replace in production
30
Start 1 or 500 instances from
same image
31
• Atomic Deployments
• Reversible
• Ephemeral
• Forces State isolation and boundaries
• Fast Recovery
• Testability
32
Automate every layer
33
Empty machine to full image
must be automated
34
Why we needed to
build this way
35
make innovation faster and
remove fear
36
“Fear is the path to the dark side. Fear
leads to Inertia. Inertia leads to Paralysis.
Paralysis leads to going out of business.”
37
DevOps Yoda
As developers we are
responsible for shipping our
features
38
Code in repo is not shipping
39
It’s shipped when at customer
and we get actionable metrics
40
Need to embrace process and
push for it, not wait for somebody
else to come up with it.
