In a world of dynamic, ever evolving workloads due to micro-services and multi-cloud deployments, it is not a tractable problem for humans.

- 40. Key take-aways OpenEBS always available multi-cloud block services are delivered via containerized microservices Granularity: Each pod has its own block protocol stack, tiering engine, QoS engine and more. SLAs per POD. Performance & efficiency: access patterns maintained per-volume. Hot-data on NVMe-Flash or on 3DX-Memory. Cold- data on slower disks / SAN/ Cloud-Storage/S3. Scalability: Metadata based on “size of the volume” & not on “number of volumes”. Can reduce metadata traversal 100x. Blast radius: Eliminates risk of scale out storage system corruption. And much, much more such as cost savings due to resource efficiency, innate multitenancy, and cross cloud portability The Conway’s Law benefits might be the most important - innovation unlocked ✓ ✓ ✓ ✓ 2017 MayaData Inc.
