Cloud Development and Deployment with CloudBees

Overview of this book

CloudBees offers a Platform as a Service (PaaS) to build, run, manage web applications, and support the entire application lifecycle right from development to deployment.The development and deployment of web- and mobile-based Java applications are the basic services that CloudBees has to offer. With these services you can efficiently build and enhance applications, and connect them to existing networks and systems. Cloud Development and Deployment with CloudBees introduces you to the concept of Platform as a Service. It talks about the services in detail that developers can leverage in order to build, manage, and deploy their applications with ease onto the cloud. You will learn the intricacies of the CloudBees ecosystem and how it can be extended to match your specific requirements. Cloud Development and Deployment with CloudBees will get you started with the concepts of PaaS and why it is considered better than other forms of services. You will then learn to create and manage your account, understand the CloudBees ecosystem, and subscribe to the wide array of services available. After this, you will use the clickStart feature that will enable you to set up, run, and host your application on the cloud. You will also venture out into the development phase by understanding Jenkins and how it would help you to build, maintain, and integrate your project build. You will then learn how to use the RUN@CLOUD platform to host your application, and you will also delve into cloud concepts, and understand the architectural constraints and how to monitor the application. Finally, you will deep dive into the extensive capabilities of using clickStack to create or customize your own stack.

Testing


Writing a trivial ffmpeg ClickStack is easy, and testing it directly on RUN@cloud with a demo application is fine. For more complex stacks, you'll need some way to test and diagnose them.

The local GenApp installation

GenApp is an open source framework and is well documented at http://genapp-docs.cloudbees.com/. You can install a local GenApp to test your ClickStack plugins. As RUN@cloud's target environment is Arch Linux, it won't make much sense to give it a try if you don't use a Linux or an OS X system. Running on Windows using Cygwin may work, but it is not the best option.

Follow the Quick Start guide (http://genapp-docs.cloudbees.com/quickstart.html) to get an overview of the use of GenApp and ensure that everything is working fine in your environment.

GenApp uses Erlang and Python; so, as a prerequisite, associated runtime must be installed. You don't have to worry as you don't need to write much Erlang code to test a ClickStack. Deploying an application on a local GenApp is...
