3. Let's imagine...
 Research organization
 Large flow of data (20 TB a day)
 Analyze this data
 Data processing needs continued
increasing
 Require different computing needs
 Employees all over the world
 How do you handle that much data
and make it available to your
employees/collaborators world wide?

4. What is OpenStack?
 Set of software tools for building and
managing clouds.
 Manages compute, storage, and
networking resources from a single
point.
 Separated into projects which
communicate through public APIs
 Scalable
 Founded by NASA and Rackspace in
2010

5. Components (aka architecture):
CC BY-SA 3.0 Red Hat, Inc.

6. Nova (Compute)
➔
Manages and automates pools of computer resources
➔
Used for deploying and managing large numbers of virtual machines
and other instances to handle computing tasks
➔
Supports multiple hypervisors (software that creates virtual machines)

7. Cinder (Block Storage)
 Block storage (files are broken into little
pieces of data blocks so the disk can
store them) to guest virtual machines.
● The block storage system manages the
creation, attaching and detaching of
the block devices to servers.
 Data access speed is the most
important consideration.
 Create/delete/list volumes and
snapshots.

8. Glance (Image service)
➔
Manages "images" (virtual copies) of hard
disks and uses them as templates when
deploying new virtual machine instances.
➔
Configure, create, delete, and control
access to images
➔
Store and catalog an unlimited number of
backups

9. Swift (Object Storage)
● Distributed storage to prevent
any single point of failure
● API-accessible
● Containers
● Store VM images, backups, and archives
as well as smaller files, such as photos
and email messages
● Objects are referred by unique identifier
instead of location

10. Neutron (Networking)

System for managing networks and IP addresses

Provides networking models for different applications or
user groups

Relieve the stress on the network in cloud environments

Floating IP addresses allow traffic to be dynamically
rerouted to any of your compute resources

Extension framework that allows intrusion detection
systems (IDS), load balancing, firewalls and virtual private
networks (VPN)

11. Keystone (Identity)
➔ Central list of all of the users of the
OpenStack cloud, mapped against all of
the services provided by the cloud which
they have permission to use.
➔ Authentication & means of access
➔ Users, tenants, and roles
Admin powerz!

12. Other projects
➔
Ceiliometer (Telemetry)
– Provide efficient collection of metering
data, in terms of CPU and network costs
– Monitoring notifications sent from
existing services or by polling the
infrastructure
– Single Point Of Contact for billing
systems
➔
Trove (Database Service)
– Trove is a database-as-a-
service provisioning relational
and non-relational database
engines

13. Other projects
➔
Sahara (Data processing)
– Simple means to provision a
Hadoop cluster on OpenStack
– Analyze big data
➔
Heat (Orchestration)
– Heat is a service to orchestrate
multiple composite cloud
applications using templates

14. Other projects
Incubated:
➔
Marconi (Messaging)
➔
Ironic (Bare Metal)
➔
Barbican (Key management)
How do we access all these projects?

15. Horizon (Dashboard)
graphical Web-based dashboard

19. CERN
● Home of the Large
Hydron Collider (27 km
circumference & 100
meters under the
ground)
● 10,000+ scientists
● Create particle
collisions (10 millions
of collisions every
second)
● Multistorey-high
digital cameras
records thousands of
images per second of
debris from the LHC
particle collision
● 35PB/year
● Physics all around the
world analyze data

20. CERN
● 10,000 servers, 75,000 disks, and 100
petabytes of data stored in mass-
storage systems
● 200 Gbp/s network
● Reached its power and cooling capacity

21. CERN
Data is saved to tape storage and
then distributed to the more than
150 sites worldwide that comprise
the Worldwide LHC (Large Hadron
Collider) Computing Grid (WLCG)
for analysis

22. CERN
● The CERN Worldwide LHC Computing Grid
(WLCG) is massive!
● Data is sent to its 12 Tier 1 sites around the
world
● 140+ Tier 2 sites used for creation of
simulated data and analysis. In all, CERN
mass-storage systems store more than 100
PB of data.
(1 petabyte = 1,000 terrabytes)

23. CERN

● 65,000 cores across
multiple data
centers, supporting
multiple users
● ~1300 compute
nodes
● Configured with
Puppet
● Runs on nova,
glance, keystone,
neutron, ceilometer,
and horizon
● Ceph as storage for

● OpenStack runs virtual machines to support
self-service for developers
● OpenStack APIs have accelerated the
company’s development process by making
applications easier to implement and having
one consistent standard across their
environment.
