Introduction

• A Guide to Running Stateful Applications in Kubernetes
• 5 Cloud Native Storage Startups To Watch Out For In 2019

Solutions

• OpenEBS extends the benefits of software-defined storage to cloud native through the container attached approach.
  • MayaData Founder of OpenEBS
• StorageOS
• Rook
• Robin
• Reduxio
• Portworx
• Longhorn
  • thenewstack.io: Rancher Donates its ‘Longhorn’ Kubernetes Persistent Storage Software to CNCF. Gluster and Ceph were “designed to be run by some storage admin. In the Kubernetes world, a lot of these things tend to be deployed by DevOps teams, so (the storage layer) needs to be a lot more lightweight and a lot simpler.” — Rancher Labs CEO Sheng Liang.

OpenShift Container Storage Operator (OCS)

• State of OpenShift Container Storage

OCS 3 (OpenShift 3)

• OpenShift Container Storage based on GlusterFS technology.
• Not OpenShift 4 compliant: Migration tooling will be available to facilitate the move to OCS 4.x (OpenShift Gluster APP Mitration Tool).

OCS 4 (OpenShift 4)

• OCS Operator based on Rook.io with Operator LifeCycle Manager (OLM).
• Tech Stack:
  • Rook (don’t confuse this with non-redhat “Rook Ceph” -> RH ref).
    • Replaces Heketi (OpenShift 3)
    • Uses Red Hat Ceph Storage and Noobaa.
  • Red Hat Ceph Storage
  • Noobaa:
    • Red Hat Multi Cloud Gateway (AWS, Azure, GCP, etc)
    • Asynchronous replication of data between my local ceph and my cloud provider
    • Deduplication
    • Compression
    • Encryption
• Backups available in OpenShift 4.2+ (Snapshots + Restore of Volumes)
