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.

DEV@cloud


CloudBees, DEV@cloud offers Jenkins as a Service that is hosted in the Cloud. This can be used as a standalone SaaS; but as ClickStart demonstrated, it also fits well in the CloudBees integrated development chain.

The following screenshot shows a Jenkins instance that has been set for our CloudBees account. The ClickStart we used generated a build job, but we can define many more and even organize them into views or group them into folders. A Jenkins instance for a large company can handle thousands of jobs!

Each job defines what should be done as an automated task, and also tells when it should be done. Jenkins UI is fully web-based and offers lots of options (depending on the installed plugins), which are grouped into sections. All of them can grow depending on the installed plugins. The sections defined in the Builds menu are as follows:

  • The main section defines the job name, parameters, and the Jenkins execution constraints (where to build and when to purge data).

  • The Source Code...
