6. Pets vs Cattle (yes, again)
Scale Out
Scale Up
- Servers are like cattle
- Servers are like pets
Pets are given names, are unique,
lovingly hand raised and cared for.
When they get ill, you nurse them
back to health.

Cattle are given numbers and are
almost identical to each other.
When they get ill, you get another
one.

Editor's Notes
Let's begin from the beginning
Allow to introduce myself and I'll be talking about today
I've been building scalable systems for the last 10 years, as well as the teams that are responsible for managing those systems.
Huge Open Source enthusiast. When things really get rough you're only in control of you own fate if youcan dive into the source code.
So without farther delay, I'll introduce Cloud Computing, and OpenStack.
Whole lot of definitions
To me, it isn't more than to deliver computing as a service (rather and as a product)
It isn't the 1st time this shift in technology happens. Think of Electrocity, for instance
Electricity as a Service!!How utterly cool is that?
Consolidation of HardwareFewer, bigger servers
Workload managementOver-subscribed services get more hardware
App protectionFault tolerance, High Availability & Live migration
ScalabilityAdd resources to VMs on the fly
Do you remember when we used to name servers? We used all sort of names: planets, sesame street characters, NBA players, planets, the Simpsons, etc.
All that is long gone, isn't it?
Utilization is key
Different instance sizes
Fully utilize physical servers
Here is where the cost come into play
2012, August 2012: Red Hat OpenStack
September 2012: OpenStack Foundation
October 2012: Havana released
NASA: Nova, networking, volumes
Rackspace: Swift
To play it fareNot the only Open Cloud platform.
Active Participants in the community
Global size of the different communities
On the development front - very similar trend
Monthly commit (changes)
Big increases in activity when a release approaches
People contributing code
OpenStack is sky rocketing!
Let me clarify something about the OpenStack releases and the name convention that we follow
Consecutive initial Letters
Short names
Named after somewhere close to the venue of the OpenStack Summit
Don't be confused
It's a powerful and complex system
The conceptual design isn't a tough to comprehend
Let me briefly introduce you the main components in OpenStack
- Modular Architecture
- Designed to scale out
- Growing set of core services
- Holds information about users, tenants, roles
- Policies enforcement
- Service catalog
- Backends: LDAP, SQL, Key Value Stores
- Block devices exposes to Vms
- Independent from VMS life cycle
- Backends: GlusterFS, NetApp, EMC, etc
- Neutron, formerly known as Quantum
- API for networking
- Provide connectivity to Vms
- Decouples physical and Local view of the network
- Backends: OpenFlow, Linux Bridge, Cisco, ...
- Generic Object Storage
- Highly Scalable
- Multiple Redundancy
- Store and Retrieve thru RESTful interface
- Kind of like Amazon S3
Two parts
- Horizon: The framework to build interfaces
- Dashboard: UI reference implementation (Django)
- Evolution
- Folsom: Nova, Cinder, Glance and Swift
- Grizzly: Basic Neutron
- Havana: Greatly improved Neutron support
Open nature of OpenStack
Many different technology options. Survey.
Truly Amazing Community
Involved my many successful Open Source projects:
GNU
GNOME
OpenSolaris & OpenJDK
Cherokee
Never saw a project like this.
Growth speed is unprecedented
Outstanding development model
Intro the development model – still evolving
- Large clusters testing the code once and again
- Platforms and OSes
- Versions
- Deployment methods
- Configurations
A change will only make it when all those tests are successful and other developers bless it.
- Code in the open (mainly GitHub)
- Number of authors more than tripped
- As well as the number of commits
Companies backing up the project raised by 250%
Currently more than... wait for it.. 150
- Different companies have different roles and involvement the project
- Graph represents somehow the global contribution of the Top 10 companies
- I'm really proud Red Hat is investing so much resources in the development and support of OpenStack.
- Here you have another example
- Closed bugs in the latest release of OpenStack
- We do believe in Open Source, and therefore we invest on it. You have to put your money where your mouth is, right?
Deploy OpenStack isn't easy. For that, Red Hat has also made a big effort creating RDO.
