- 32. Cloud Foundry: Services 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 • Cassandra? COBOL / CICS, Oracle CONFIDENTIAL
- 33. 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 CONFIDENTIAL

- Hello, thank you or having me. Im pleased to have the opportunity to introduce you today to Spring and the SpringSource Tool Suite \n\nMy name is Josh Long. I serve as the developer advocate for the Spring framework. I&#x2019;ve used it in earnest and advocated it for many years now. i&#x2019;m an author on 3 books on the technology, as well as a comitter to many of the Spring projects. Additionally, I take community activism very seriously and do my best to participate in the community. Sometimes this means answering question on Twitter, or in the forums, or helping contribute to the InfoQ.com and Artima.com communities\n
- So I now want to walk you through the process of getting started with Cloud Foundry\n
- The first step is to register at Cloud Foundry.com\n\nYou enter your email address along with a promo code to expedite signup\n
- You will then get a welcome email containing your temporary password\n
- Once you have been signed up you can then start using CloudFoundry.com\n\nYou have several different tools to choose from.\n\nI want to begin by showing you the command line tool- vmc\n

- This is what happens when you run the command.\n

- Once you have deployed the application there are various commands that you can use.\n\nFor example, you can scale the application using the vmc scale command.\n\nIn this example, I&#x2019;m added two more instances of the application.\n\n\n
- \n
- You can also use Cloud foundry from within STS, which is an eclipse-based IDE for building enterprise java applications.\n

- The packaging of the application into a droplet is handled by a framework-specific staging plugin.\n\nIt creates a zip file that contains everything the DEA needs to run the application.\nAt its root at two scripts: start and stop that are invoked by the DEA.\n
- What the staging plugin does is very dependent on the framework.\nFor example, the Spring staging plugin alters the application&#x2019;s configuration.\n\n\n\n
- Load balancer\n Sends request to one of many Routers\n Router\n Selects application instance\n Handles sticky sessions\n Forwards request to application instance\n Application instance\n Handles request\n \n
- Die when you are dead\n
- In all of this discussion you might be wondering where the VMs are?\n
- So I now want to walk you through the process of getting started with Cloud Foundry\n
- MCF is CF packaged as a VMware virtual machine.\nIt contains all the services as CloudFoundry.com\n\nIt&#x2019;s especially useful as a developer sandbox:\n* You can use the services for your JUNIT integration tests\n* You can also run your application for development and testing\n\nFor Java developers\n
- To run MCF there are a few things that you need\n
- The first step is to register and login to CF.com\n\n\n
- You then have to pick a unique domain name for your MCF.\n
- CF then displays a configuration token that you must later enter into MCF\n
- You then download and unzip MCF and open the micro.VMX\nWhich launches FUSION or VMware player\n
