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.

The RUN@cloud architecture


RUN@cloud uses a layered and extensible architecture. A low-level, infrastructure-aware layer is written in Erlang, which manages server allocation and resource sharing. It's a general purpose layer, which is not tied to a specific runtime. ClickStack runs on top of it and provides runtime specialization. A typical ClickStack will handle the preparation of a Java EE application server, but it could set up a non-JVM-based runtime as well. An application is installed on this runtime. Metadata provides all the required information for each layer to provide adequate resources, and exposes them to the upper layer.

The lower level of the architecture includes GenApp, a low-level process orchestrator written in Erlang. It receives deployment API application commands with metadata on the application to be deployed. Read more about it at http://genapp-docs.cloudbees.com/.

ClickStack executes on top of GenApp. ClickStack is responsible for setting up the runtime environment...
