First consolidate, then innovate
Challenges
People Full stack engineers that are willing to wear a
pager are rare.
Complexity Many simple bricks, tied together, work well; until
they don’t.
OpenSource Communities that grow quickly are great; until
they don’t.
Transparency Everyone knows everything.
Infrastructure as code Ops teams using GitHub.
Failure Daily. Ones you notice & understand are good.
Persistence You need it. To keep going. And to enable the
next wave in analytics - machine learning.

What projects?
Hard to overstate the promise of
Kubernetes● Makes real the hype that crazy people were
throwing around about software defined
years ago*
● Part of a move to DevOps & NoOps
○ Which is disrupting all tech vendors
○ Also disrupting most industries

The magic of K8S
Manifests express intent
stateless
Before OpenEBS DevOps workflow broken
Manifests express intent
K8S used rarely for apps requiring persistence
because they require brittle tight coupling.
Container 1 Container 2 Container 2
Hard wired connections via plug-in
stateless
stateful
NAS SAN S3 NAS SAN S3Legacy storage
Flocker, Docker,
EMC plug-ins
Manifests express intent
stateless stateful
No changes to DevOps workflow even for containers requiring
persistence. Users manifest their intent and the storage and
storage controllers adjust automatically as needed.
MayaPolicy engine
Remote Storage
Local Storage
OpenEBS Storage Hosts
OpenEBS VSMs
OpenEBS Storage ClusterEBS
APIs
Containers and underlying storage,
local on host or dedicated storage
pods OR remote S3 or EBS storage
all grouped into a storage cloud that
just works. Billing by AWS.
Manifests express intent
With OpenEBS the workflow works
