The document discusses cloud native storage and principles for containerized applications. It introduces StorageOS as a software-defined and horizontally scalable storage platform that is optimized for databases and container workloads. StorageOS provides a volume plugin that integrates with Docker and Kubernetes to offer highly available cloud native storage.

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

Conclusion

47. K8S Storage SIG & CNCF Storage WG:
https://github.com/cncf/wg-storage
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.
