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

CONFIDENTIAL

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

CONFIDENTIAL

Cloud Foundry: Services

16

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

Demo: logging in, asking questions, & deploying from the CLI

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
