A codified series of high level steps that we have seen help engineers reach the “aha” moment of understanding how their existing development workflow will need to change when they adopt cloud native technologies like Kubernetes.

1. Kubernetes Workflow 101: From
an Idea to an API in Production
Daniel Bryant

Cloud-Native Microservices

• Modularisation
• Aka “microservices”
• Independently:
• Build
• Release
• Scale
• Operate

3. @danielbryantuk3
“You build it, you run it”
- Werner Vogels, CTO Amazon
i.e. you own what you code,
from idea to production

Workflow: Full Cycle Development
4
• App teams have full responsibility (and authority) for
delivering a service, and ultimately, value to users
• Increase agility by accelerating the feedback loop

5. The Kubernetes Migration Journey

Exploration
Organizational buy-in Cloud-native organization
We’re not actually moving faster
Let’s release our microservices as a monolith

6. 6
Safety. The ability to
quickly ship changes to
production, without
fear.

7. Safety requires multiple strategies
7
Prevention
Mitigation
Detection
Response
Most common strategy (e.g., testing).
Mitigation, detection, and response are critical
strategies for cloud-native organizations when
the application is constant flux.

8. Safety Strategies
8
Prevention
Mitigation
Detection
Response
• Testing: integration tests, user acceptance tests, …
• High-fidelity replica environments for dev & test
• Engineering for resilience
• Progressive delivery: canary release, blue/green rollouts, …
• Observability
• Chaos engineering
• Fast dev / test loops
• Blameless postmortems
• Runbooks & game days
• Instant rollback & traceability

9. Safety needs to
be part of your
workflow.
