Main Risk: Lock In
10
Welcome to the hotel California
Such a lovely place
Such a lovely face
Plenty of room at the hotel California
Any time of year, you can find it here
Last thing I remember, I was
Running for the door
I had to find the passage back
To the place I was before
’relax,’ said the night man,
We are programmed to receive.
You can checkout any time you like,
But you can never leave!

Cloud Foundry: Services
15
§ Services are one of the extensibility planes in Cloud Foundry• there are more services being contributed by the community daily!
§ MySQL, Redis, MongoDB, RabbitMQ, PostgreSQL
§ Services may be shared across applications
§ Cloud Foundry abstracts the provisioning aspect of services through a uniform API hosted in the Cloud Controller
§ It’s very easy to take an app and add a service to the app in a uniform way

Cloud Foundry: Services

§ Take Advantage of Services • they cost nothing to setup
• they deliver value
§ They Encourage Better Architectures• Need a fast read-write cache? Redis is ready to go!
• Need to store long-tail documents? Give MongoDB a try
• Need to decouple what applications do from when they do it? Use messaging and RabbitMQ

Self Healing Infrastructure§ If an application instance crashes
• DEA detects unexpected exit => DEA broadcasts message• Routers remove instance from routing• Health manager notifies Cloud Controller• Cloud Controller re-launches instance
§ If an DEA VM crashes• Application instances become unavailable• Health Manager notices the missing instances and notifies the
Cloud Controller• Cloud Controller requests application instances to be started• Existing DEA will reply and start the applications
