This document summarizes a presentation about Ceph and OpenStack. The presentation introduces Ceph as software that provides object, block, and file storage. It discusses how Ceph can run on commodity hardware and scale to exabyte sizes. The presentation also covers how Ceph integrates well with OpenStack for tasks like live instance migration between compute nodes with shared Ceph storage. It outlines upcoming improvements to Ceph in areas like geo-replication, erasure coding, and tiering. The document encourages community involvement through online summits, Ceph Days events, IRC channels, and mailing lists.

Welcome!

On commodity hardware
Ceph can run on any
infrastructure, metal
or virtualized to
provide a cheap and
powerful storage
cluster.
Object, block, and file
Low overhead doesn’t
mean just hardware,
it means people too!
Awesomesauce
Infrastructure-aware
placement algorithm
allows you to do really
cool stuff.
Huge and beyond
Designed for exabyte,
current
implementations in
the multi-petabyte.
HPC, Big Data, Cloud,
raw storage.
…besides wicked-awesome?

Come for the block
Stay for the object and file
Cinders and Glances and …bears?
Reduced Overhead
Easier to manage one cluster
“Other Stuff”
Identity with Keystone, CephFS
prototypes,
Gateway Drug

8. 8
Squash Hotspots
Multiple hosts = parallel workload
But what does that mean?
Instant Clones
No time to boot for many images
Live migration
Shared storage allows you to
move instances between compute
nodes transparently.
Blocks are delicious

9. 9
Speak SWIFT
Native support for SWIFT
And less filling!
Keystone
Integration with identity
Horizontal Scaling
Easy with HAProxy or others
Objects can juggle

Neat prototypes
Image distribution to hypervisors
You can dress them up, but you can’t take them anywhere
Still early
You can fix that!
Outside uses
Great way to combine resources.
Files are tricksy

OBJECTS VIRTUAL DISKS FILES & DIRECTORIES
CEPH
FILE SYSTEM
A distributed, scale-out
filesystem with POSIX
semantics that provides
storage for a legacy and
modern applications
CEPH
GATEWAY
A powerful S3- and Swift-
compatible gateway that
brings the power of the
Ceph Object Store to
modern applications
CEPH
BLOCK DEVICE
A distributed virtual block
device that delivers high-
performance, cost-effective
storage for virtual machines
and legacy applications
CEPH OBJECT STORE
A reliable, easy to manage, next-generation distributed object
store that provides storage of unstructured data for applications

Procedural, Ruby
Written in Ruby, this
is more of the dev-
side of DevOps. Once
you get past the
learning curve it’s
powerful though.
Model-driven
Aimed more at the
sysadmin, this
procedural tool has a
very wide penetration
(even on Windows!).
Agentless, whole stack
Using the built-in
OpenSSH in your OS,
this super easy tool
goes further up the
stack than most.
Fast, 0MQ
Using ZeroMQ this tool
is designed for massive
scale and fast, fast, fast.
Unfortunately 0MQ has
no built in encryption.
The new hotness
Orchestration
Chef Puppet Ansible Salt

Canonical Unleashed
Being language
agnostic, this tool can
completely encapsulate
a service. Can also
handle provisioning all
the way down to
hardware.
Dell has skin in the game
Complete operations
platform that can dive
all the way down to
BIOS/RAID level.
Others are joining in
Custom provisioning
and orchestration,
just one example of
how busy this corner
of the market is.
Doing it w/o a tool
If you prefer not to
use a tool, Ceph gives
you an easy way to
deploy your cluster by
hand.

And you!
The community does a lot to drive
direction, we love input

code)!

An ongoing process
While the first pass
for disaster recovery
is done, we want to
get to built-in, world-
wide replication.
Reception efficiency
Currently underway
in the community!
Headed to dynamic
Can already do this in
a static pool-based
setup. Looking to get
to a use-based
migration.
Making it open-er
Been talking about it
forever. The time is
coming!
Hop on board!
