These slides describe the On-Premise deployment of EBS style storage platform using OpenEBS

1. OpenEBS
Containerized storage for containers
Use cases

2. What is OpenEBS ?
➔ OpenEBS is
containerized
storage for
containers
➔ OpenEBS solves the persistent storage issue for
containers
Legacy
storage
X
Application
Pod
★ Application pod management
automatically takes care of storage
volume management

3. What is Maya ?
Maya

4. Manifests
express
intent
K8S used with special care 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 S3
Without OpenEBS DevOps workflow is broken

5. 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.

Local Storage
OpenEBS Storage

OpenEBS VSMs
OpenEBS Storage Cluster
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.

With OpenEBS the workflow works

6. DevOps operations with OpenEBS
OpenEBS got the storage ops off my back!
Because of OpenEBS we are rolling into
production.

7. How is OpenEBS built ?
Storage containerization
Storage orchestration
Deep storage operations
Core Storage features
is built using
is integrated with
is built into (OpenEBS Maya)
is built into (OpenEBS)
Smart Capacity Management
Volume Latency Monitoringand Auto-healing
Adapt to varying workloads - Application Aware Storage (Zones)
AWS EBS Like APIs
Storage Analytics!
Enterprise HA
Intelligent QoS
DistributedScaleout
Smart Tiering for higherperformance

8. OpenEBS - Word of mouth
Containerized storage for containers
Calico / Flannel owns networking for K8S. OpenEBS owns
storage.
The only open source solution built for this. CEPH is not built
to be containerized.
I run (use) OpenEBS just like I run (use) K8S (EBS).
OpenEBS got the storage ops off my back! Because of OpenEBS
we are rolling into production.

9. Typical Use
cases

10. Usecase :
Reuse existing SAN in
your cloud to build
container friendly storage
platform

11. Build container friendly storage platform
AWS
VMs
EBSDocker
Application Pod (Application has
container-native storage)
● The existing SAN storage (EBS or GCP PD or
any other block storage) in your cloud can be
integrated into K8s application pods by
OpenEBS
● Persistent storage need not be managed
separately in your cloud
● Your persistent storage is managed from within
your application yaml files

12. Usecase :
Build AWS EBS or GCP PD
type platform On-Premise

13. Deploy EBS style platform On-Premise (Dedicated)
Your data center
Bare metal servers
Docker engines (Compute)
Bare metal storage
servers
Docker engines (OpenEBS)
Application
pod
yaml
A single application yaml
file controls both the
compute and storage
needs

14. Deploy EBS style platform On-Premise (Hyperconverged)
Your data center
Bare metal servers
Docker engines (Compute+OpenEBS)
Application
pod
yaml
A single application yaml
file controls both the
compute and storage
needs

15. Comparing AWS EBS & OpenEBS
Feature AWS EBS OpenEBS
Network Block Storage as a
service
Yes No. This is a technology
that can be used to build a
service or platform like AWS
EBS
Technology form factor Unknown Open Source
High Availability grade Five nines of availability Five nines of availability
Availability zones Yes Yes
Point in time Snapshots to
S3
Yes Yes, to S3 or any S3
equivalent (locally hosted
Minio for example)

16. Connectivity in AWS EBS (Optimized for Cloud service)
Login into AWS Console
Create an EBS volume
Attach to an instance
Format and put it to use
by application

17. Connectivity in OpenEBS (Optimized for Container service)
Login into Kubernetes
Set up an application
yaml with OpenEBS as
the storage provider
Volume is created on
OpenEBS and mounted
on K8S minion
Format and put it to use
by application
kubectl create -f demo-mysql-iscsi.yaml

19. Other features comparison of AWS EBS & OpenEBS
Feature AWS EBS OpenEBS
Volume migration across tiers
(Magnetic, General Purpose
SSD, Provisioned IOPS)
Yes Yes, VSMs can be migrated
seamlessly across tiers.
QoS control Yes (Provisioned IOPS) Yes, granular control of IOPS
on a per volume basis
Burst IOPS, credit bucket for
unused IOPS
Yes Yes. Min/Max IOPS, burst
IOPS, credit bucket
functionality
Auto scaling of the storage
nodes
Yes (Not sure. Internal to EBS
architecture)
Yes. OpenEBS storage nodes
are added to clusters to allow
auto scaling of either capacity
or performance

21. http://www.networkworld.com/article/3159735/cloud-computing/containers-what-are-containers.html
What is Containerization
Code and it is
dependencies are
packaged into
“container” executable
Runs in any supported
runtime
Light-weight and spins
up faster.

22. Where does OpenEBS fit?
DevOps and containers are the future
Which is already here, but unevenly distributed
Real computing needs persistence
But - persistence for DevOps & containers is broken
