16 what does Cloud Foundry offer? 10

17 Cloud Foundry: Choice of Runtimes 11

18 Frameworks and Runtimes Supported Out of the Box Java (.WAR files, on Tomcat. Spring s an ideal choice here, of course..) Scala (Lift, Play!) Ruby (Rails, Sinatra, etc.) Node.js Ecosystem Partners.NET (Uhuru, Tier3) Python (Stackato) PHP (AppFog) Haskell (1) Erlang (2) 1) 2)

19 Cloud Foundry: Choice of Clouds 13

20 Main Risk: Lock In 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! -the Eagles 14

26 Cloud Foundry: Services 20

27 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 21

28 Accessing Your Services Debugging and accessing the data locally Caldecott --> Service tunneling. Access your Cloud Foundry service as if it was local. 22

29 Demo: logging in, asking questions, & deploying from the CLI 23

30 Demo: Using the tunnel to talk to your services 24

31 Demo: developing with Eclipse & STS 25

42 About the staging plugin Framework specific Creates a zip file = black box Contains everything necessary for DEA to run the application Two scripts: start.sh, stop.sh 27

43 Staging plugin for the Spring framework Adds CloudAutoStagingBeanFactoryPostProcessor bean: Modifies bean definitions Implements auto-reconfiguration Defines CloudApplicationContextInitializer in web.xml Activates cloud profile Defines PropertySource for CloudEnvironment properties 28

46 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

47 But where are the VMs?!? Cloud Foundry has a layered architecture Cloud Controller, DEA, layer = processes VM management layer Benefits: decoupling, simplicity,. CloudFoundry.com creates vsphere VMs running different Cloud Foundry components

48 What is in Micro Cloud Foundry? App Instances Services Open source Platform as a Service project A cloud packaged as a VMware Virtual Machine Use as a developer sandbox Use the services from Junit integration tests Deploy your application for functional testing Remote debugging from STS 32

49 Pre-requisites for using Micro Cloud Foundry Minimum 1 GB Minimum 8 GB Internet Connectivity RAM Disk (w/dhcp is ideal) VMC STS Command line GUI 33
