“Kubernetes is rare, if not unique, in
the open source world, in that it was
defined very early on as both a project
and a community.”

“Send something from A to B”
Compared to the library approach:
• Better separation of concerns
• Language agnostic
• Observability
• Dynamic management
An abstraction layer for a reliable network

Case study: Apester + Linkerd
cncf.io/case-study/apester/
Challenge: Developers forget to set timeouts on
requests, leading to outages
Solution: Enforce consistent timeouts using Linkerd

Case study: VSCO + Envoy
cncf.io/case-study/vsco/
Problem: Serve gRPC and HTTP/2 directly to mobile
clients through edge load balancers
Solution: Deploy Envoy across 50+ microservices

42. The new norms of cloud native

“It’s not an option not to do open source.
If we don’t get involved with cloud native and
take the lead, we will fall behind our
competitors.”

Challenging new norms
1. Individuals over companies
2. Influence comes from consistent contributions over
time
3. Consensus over hierarchy
4. Be visible
