Like virtualization before it, container technology will evolve from a DevOps initiative to an enterprise requirement. Docker is leading that evolution as it promises to bring greater efficiency to the data center than we ever thought possible with the virtual machine construct. However, companies implementing Docker in production will realize that persistent data storage is not easy. As a result, the development of Docker to an enterprise class solution drives new requirements on the storage infrastructure: 1. Hyper-Scalability 2. Advanced but Flexible Data Services 3. Multiple Access Methods 4. A Software Foundation

7. What Are Containers?
● An abstraction similar to
a virtual machine but
more granular
● Virtual machines abstract
the entire device
● Containers abstract the
operating system kernel
● All containers must run
the same operating
system

8. What Is Docker?
● Container Technology Based on
LXC (Linux Containers)
● Docker is easier and safer to
deploy than other technologies
● Standardization through
Partnership with Canonical,
Google, Red Hat, Parallels

9. Why is Docker so Popular with
Developers?
● Developers can use containers to pack,
ship and run any application, anywhere
● Docker containers are easy to deploy in
the cloud
● Easy to incorporate into DevOps
applications like Puppet, Chef, Vagrant
and Ansible
● Docker makes it possible to set up local
development environments that are exactly
like a live server

10. Why is Docker Marching into the Data
Center?
● Docker enables more applications on
the same hardware
● Docker makes deployment and
migration of application updated
easier
● Docker makes operating system
upgrades and application updates
easier
● But we need stateful, shared access
to data

11. The State of Docker Storage
● In Docker 1.0
o Storage was stateless. When a container was removed so was
its data
o There was a limited ability to have multiple containers access
the same storage
● In Docker 2.0
o Introduced the concept of volumes
- Multiple containers could access the same volume
o ClusterHQ delivers Flocker API
- Container Data Management for Dockerized application
o Shared, Interactive Containers are a reality but is the storage
infrastructure ready?

12. The Uniqueness of Docker I/O
● All writes are dynamic
● Any modification that a container
deviates from the master has to be
tracked, separately in real-time
● High Level of Read I/O since sub-
containers require code from the master
● Highly variable I/O peaks as hundreds
of containers are created or
decommissioned

13. The Top 4 Requirements for Docker
Storage
● Hyper-scale Storage
o Scale performance and capacity
o Highly parallel environment
o Turnkey
● Robust Data Services
● Multiple Protocols (REST, RPC, NFS, CIFS, Block)
● A Software Foundation – Flexibility to adapt to a rapidly
evolving environment
o Rapid adoption of Flocker for example
