The Best Things in Cloud Are Free

OpenStack &
Cloud Foundry
The Best Things in Cloud Are Free
(Free as in Speech, not as in Beer).

Cloud Foundry is…
The world’s leading open source platform-as-a-service.
 Supported by dozens of major organizations
 Language and framework agnostic
 Manages both VMs and containers
 Orchestrates both applications and data services
Founded and commercialized by Pivotal, Inc.

Industry Voting:
‘Cloud Foundry’ is
the standard in
PaaS

Incredible Cloud Foundry Ecosystem

CF for ‘Stackers
 How are things the same?
 How are things different?
 Why would I get involved?
 How do I get involved?
 Next Steps

How are things the same?
OpenStack & Cloud Foundry
License Apache v2.0
Community Vendors, Users, and Developers
Architecture API-based services and message-passing

OpenStack and Cloud Foundry: Shared Ecosystem

How are things different?
OpenStack Cloud Foundry
Language Python Go and Ruby
Release Cycle 6 months, integrated 2 weeks, parallel
Governance Dedicated Foundation Linux Foundation project
Installation tools Various BOSH or Juju
Communication Hub IRC (#openstack-dev) Mailing lists
Source code & review Gerritt & Private Git GitHub & pull requests
Adoption Mostly OSS trials and
dev/test environments
Mostly commercial
production deployments

Different strokes for different folks
 Better SLAs
 Flexibility
 Speed
 Availability
 Faster Time To Market
 Mobile + Data Services
 Agile and Iterative
 Leverage OSS

“Avert the danger which has not yet come.”
- Lao Tzu

Containers Alone Aren’t Enough…

Unit of Value
IaaS == Virtual Machine
 Opaque to the system
 Orchestration is post-hoc
 System changes are
imperative (“launch” stuff)
PaaS == Application
 Containers are transparent
 Lifecycle is fully managed
 System changes are
declarative (manifest.yml)

Understanding PaaS
Turning this… …into this:
.war .jar
dependencies
libraries
service
manifest
App App App
LB
DB
Multi-server run time
environment(s)
.tar.gz

Cloud Foundry “Smart Containers”
Containers
(1st Gen)
• lxc or
cgroups
Docker (2nd
Gen)
• Net NS
• AuFS
Smart
Containers
(3rd Gen)
• HA
• ACLs
• Metrics
• Scheduling

Application patterns are changing…

Why would I care?
(Hint: It’s not just for the parties.)

Why IT loves Open Source Software
NOT Because:
 They want to change it (because most users won't)
 They think that software should be cheap or free.
But, BECAUSE:
 Open Source processes force agile development.
 Healthy OSS community guarantees multiple vendors.

Why would I care?
 Installing Cloud Foundry will unlock the value of your
OpenStack investment.
 Learning to use Cloud Foundry will move your career back
towards the creation of new business value.
 Packaging your software for CF-BOSH will open up the
behind-the-firewall market to your SaaS product.

Next steps in the CF + OpenStack world
 Deeper Neutron integration
 Bunny Breeding Efforts (more and more Rabbits)
 Unified Cloud Policy via OpenStack Congress

Do this. Now.
 Sign up for the CF and BOSH mailing lists.
 Learn how to write 12-factor applications.
 Come to a free Pivotal Cloud Foundry workshop.
 Register for the next Cloud Foundry Summit.
 Try out Pivotal Web Services (http://run.pivotal.io)
 Join the Cloud Foundry Community DC.
