Editor's Notes
- #2: \n
- #3: \n
- #4: 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
- #5: \n
- #6: I&#x2019;m first going to take a step back and talk about why I think PaaS matters to developers like us.\nI&#x2019;m then going to talk about various features of Cloud Foundry.\n
- #7: Almost all the applications that I&#x2019;ve developed over the past 10+ years have looked like this.\n\nEach application has consisted of a single WAR file\n
- #8: So let&#x2019;s imagine that you fixing a bug or working on a feature and you want to run an integration test.\n\n
- #9: And to make matters worse:\n technology trends are making this simplistic architecture inadequate\n
- #10: End users expect to access applications from their smart phones.\nIn fact, smart phones sales over took PC sales a year ago.\n
- #11: Users expect a rich, dynamic .. experience on mobile devices and browsers.\nSimply serving up HTML or HTML+JavaScript is no longer good enough.\n
- #12: Applications need to scale to support massive loads.\n
- #13: We also need to be able to scale development.\nWe need to have multiple development teams\nWe need to be able to frequently update production - perhaps many times a day.\n\nThe problem is that a monolithic WAR is an obstacle to doing that.\n\n
- #14: The end result is an architecture like this.\n\n
- #15: It was pretty easy to dev/test a WAR.\nThe challenge we have now is that ....\n\n\n
- #16: So let&#x2019;s imagine that you fixing a bug or working on a feature and you want to run an integration test.\n\n
- #17: So let&#x2019;s imagine that you fixing a bug or working on a feature and you want to run an integration test.\n\n
- #18: So what is PaaS?\n\nPaas gives you an easy way to deploy and manage your application.\nIn the Java world that means you basically upload your WAR file and the PaaS environment takes over from there.\n\nThe PaaS should also give you an easy way to scale your application up to deal with increased load; and scale your application down when the load drops.\n\nA PaaS environment should offer services such as databases, blob storage, messaging, etc.\n
- #19: \n
- #20: Cloud Foundry is an open-PaaS.\nYou can deploy and scale applications...\n
- #21: Cloud Foundry gives you a choice of frameworks and languages.\n
- #22: Cloud Foundry gives you a choice of services\n
- #23: Cloud Foundry gives you a choice of Clouds\nIt is available on public Clouds such as CF.com\nYou can run it in-house in a private Cloud.\nYou can also run it as a VM on your laptop.\nI&#x2019;ll talk more about these different types of CF.com in a moment.\n
- #24: The suppose for multiple clouds is extremely important.\nIt means that you can run your application on public and private clouds without having to rewrite it.\n
- #25: The suppose for multiple clouds is extremely important.\nIt means that you can run your application on public and private clouds without having to rewrite it.\n

- #28: The suppose for multiple clouds is extremely important.\nIt means that you can run your application on public and private clouds without having to rewrite it.\n
- #29: There are three different ways of using Cloud Foundry.\n\nThe first is CloudFoundry.com, which is a \n
- #30: As well as the public cloud, there is MCF\nIt is a VM that you can run on your desktop or laptop.\nIt has the same frameworks and services that CloudFoundry.com has.\n\nThe micro cloud particularly useful to development and testing.\nIt is your own very private sandbox.\n
- #31: There is also CloudFoundry.org, the open source project.\nIt contains all the features of CloudFoundry.com along with many community contributions.\nYou can download the source code for Cloud Foundry from github.com and run it on your own in-house infrastructure.\n
- #32: so as you can see Cloud Foundry is all about choice.\nIt allows you to make very interesting tradeoffs between implementation effort and flexibility.\n\nYou can deploy your application on a public cloud - \nThat&#x2019;s extremely easy but you are constrained by choices that the public cloud offers.\n\nAlternatively, you can download the source from Cloud Foundry.\nExtend CF to support additional frameworks and services.\nRun it on your own in-house hardware.\nThis gives you tremendous flexibility but of course, potentially requires a lot of development effort.\n\nThere is also the middle ground, of running a private cloud paas product based on Cloud Foundry.\n\n
- #33: So that&#x2019;s Cloud Foundry in a nutshell.\nThere are a great many resources that can help you get started including those shown on this slide.\n
- #34: So I now want to walk you through the process of getting started with Cloud Foundry\n
- #35: 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
- #36: You will then get a welcome email containing your temporary password\n
- #37: 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

- #60: As well as deploying your application, vmc push can also create a manifest file.\nThis captures the information you entered about your application and eliminates the need for you to re-enter it.\n\nas you can see, this file specifies the target directory, the application name, url etc.\n\n\n\n
- #61: 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

- #69: I now want to spend a few minutes talking about the Cloud Foundry architecture\n
- #70: This slide shows the Cloud Foundry architecture.\n\nThe CC exposes the WS API that the VMC CLI uses to manage applications and services. There are typically a few CC instances to handle the load and provide failover.\n\nThe DEAs are responsible for running and monitoring applications.\nA DEA typically runs on a VM and manages some number of application instances.\nThere are typically 100s of them.\n\nThere are routers that proxy HTTP requests to application instances.\nHandles load balancing etc.\n\nThere is also the health manager that monitors the state of the world and takes action when reality doesn't match expectations.\n\nAl these components are loosely coupled and communicate asynchronously through a message bus.\n

- #91: I&#x2019;m going to talk about this more later but I wanted to mention it here.\nWhen Cloud Foundry runs your application, it sets certain environment variables including VCAP_APP.\nThis env var is an JSON document that contains information that the application needs.\nFor example, the application can look at this env var to determine its URL.\nThe framework runtime can look at this env var to determine what port it should run on.\n\n#MOVED\n
- #92: You can also define your own custom environment variables in order to configure your application.\nYou use the env-add command to set an environment variable.\nThe application that then access that ENV var using some language/framework specific mechanism.\n\n#MOVED\n

- #102: I now want to talk Micro Cloud Foundry, which is a version of CF that you can download and run on your desktop or laptop.\n
- #103: 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
- #104: To run MCF there are a few things that you need\n
- #105: I now want to walk through the process of configuring Cloud Foundry\n
- #106: The first step is to register and login to CF.com\n\n\n
- #107: You then have to pick a unique domain name for your MCF.\n
- #108: CF then displays a configuration token that you must later enter into MCF\n
- #109: You then download and unzip MCF and open the micro.VMX\nWhich launches FUSION or VMware player\n

- #119: Accessing MCF through a host name is pretty cool.\nBut it does require a DNS server.\nAnd until recently that required your PC to be online\nThe very latest version of MCF and VMC support a true offline mode.\n\n
- #120: The vmc micro status command shows the online/offline state\n When you first run the command you need to specify the paths to the VM and vmrun command\n Those values are saved away so you don&#x2019;t have to re-enter them\n
- #121: You switch between online and offline modes using the vmc micro online and offline commands\n Vmc micro offline switches to offline mode\n It reconfigures DNS..\n vmc micro online switches back to online mode\n ...\n

- #133: Up until I&#x2019;ve been talking about the deployment side to PaaS.\nI now want to change gears and talk about how easy it is to create and consume services on Cloud Foundry\n
- #134: Cloud Foundry provides a variety of services\n
- #135: With Cloud Foundry, its easy to create an instance of one of these services.\nYou use the vmc create-service command, specify the type of the service and the name.\nA few seconds later you have a running service instance, \n
- #136: In order, for an application to use a service that service must be bound to the application.\nThere are a couple of different ways to do this.\nOne approach is to bind the service when the application is first deployed.\n\nThe push command as you whether you want to bind services to the application.\n
- #137: In order, for an application to use a service that service must be bound to the application.\nThere are a couple of different ways to do this.\nOne approach is to bind the service when the application is first deployed.\n\nThe push command as you whether you want to bind services to the application.\n
- #138: Another option is to use the bind-service command to bind a service to an already running application\n
- #139: You can also bind services from within STS\n
- #140: \nLet&#x2019;s look at how you deploy an application that consumes Cloud Foundry services\n
- #141: The survey application stores information about customers and their answers to survey questions.\n\nWhat&#x2019;s particulary interesting about this application is that it uses what we call cross-store persistence.\n\nCustomers are stored in a MySQL database.\nBut the survey questions are stored in MongoDB, which is a document-oriented NoSQL database.\n\n\n
- #142: \n
- #143: So how does binding actually work?\n\nWhat actually happens, is that CF sets an environment variable called VCAP_SERVICES.\nLike VCAP_APPLICATION its a JSON document.\nAnd it contains information about the services that have been bound to the application.\n\nFor example, with a MySQL database VCAP_SERVICES specifies the host, port, user name, password and schema name. An application can use this information to connect to the database.\n
- #144: There are a couple of different ways of accessing the service bindings.\n\nThe brute force approach is to get the value of the env var and parse the JSON.\nThat works in every language.\nBut it is a lot of work.\n
- #145: Some frameworks simplify the process of accessing bound services.\nFor example, Cloud Foundry provides some really easy ways to access services from a Spring application.\n
- #146: Some frameworks simplify the process of accessing bound services.\nFor example, Cloud Foundry provides some really easy ways to access services from a Spring application.\n
- #147: Some frameworks simplify the process of accessing bound services.\nFor example, Cloud Foundry provides some really easy ways to access services from a Spring application.\n
- #148: Ruby also has some high-level support.\nCloud Foundry can automatically reconfigure a Ruby application to talk to the bound services.\n
- #149: \n
- #150: So this all good stuff.\nBut what if you want to access the services outside of application.\nFor example, you might want to run a database tool to dump or restore test data.\nOr you might want to use the services from a JUNIT integration that you run in your IDE\n\n
- #151: To support these use cases, Cloud foundry has a tool called Caldecott.\nCaldecott let&#x2019;s you create a tunnel to a service running within CF.\nIt works with both the MCF and also CF.com\n
- #152: To use caldecott you first need to install the Ruby gem.\n
- #153: Once you have done that you are ready to access the services.\nLet&#x2019;s look at a demo.\n
