What is Cloud Native?
@oicheryl
Horizontally scalable
No single point of failure
Resilient and self healing
Minimal operator overhead
Decoupled from the underlying platform

@oicheryl

27. Centralised file system: NFS
@oicheryl
Single point of failure
Hard to scale horizontally
No native integration

28. Storage array: Dell EMC
@oicheryl

29. Storage array: Dell EMC
@oicheryl
Deterministic performance
Vendor lock in
No thin provisioning

47. K8S Storage SIG / CNCF Storage WG
Objective is to define an industry standard “Container
Storage Interface” (CSI) that will enable storage vendors to
develop a plugin once and have it work across a number of
container orchestration systems.
