Big software and little software
Mark Shuttleworth
the phase change of modern software
Free software is becoming expensive
Software cost
Operations cost
this is the age of big software

Story
Walk around your developer desks and look at the whiteboards. This is what you’ll see - collections of services connected up to make applications.
What matters to the developer is what services are involved - not the details of how many machines there are, or which cloud they are on, or whether they are big machines or small machines, or whether all the services are installed on the same machine.
The picture captures the services.
Service orchestration is about focusing on the services, not the machines.
Let software decide what happens on a particular machine, you want your developers to focus on the services independent of the actual implementation.
Look familiar? Check your whiteboards ;)

Charms are reusable open source operations
Juju is “open source SAAS operations”
