Overview of this book

Docker containers transform application delivery technologies to make them faster and more reproducible, and to reduce the amount of time wasted on configuration. Managing Docker containers in the multi-node or multi-datacenter environment is a big challenge, which is why container management platforms are required. OpenShift is a new generation of container management platforms built on top of both Docker and Kubernetes. It brings additional functionality to the table, something that is lacking in Kubernetes. This new functionality significantly helps software development teams to bring software development processes to a whole new level. In this book, we’ll start by explaining the container architecture, Docker, and CRI-O overviews. Then, we'll look at container orchestration and Kubernetes. We’ll cover OpenShift installation, and its basic and advanced components. Moving on, we’ll deep dive into concepts such as deploying application OpenShift. You’ll learn how to set up an end-to-end delivery pipeline while working with applications in OpenShift as a developer or DevOps. Finally, you’ll discover how to properly design OpenShift in production environments. This book gives you hands-on experience of designing, building, and operating OpenShift Origin 3.9, as well as building new applications or migrating existing applications to OpenShift.

Understanding OpenShift's business value

N-tier design is a standard application design like a three-tier web app with web, application, and database tiers. This design slowly evolved into the microservice architecture. The microservice architecture influences the industry and forces many companies to embrace this new trend and make it a new standard. The microservice architecture is much cheaper, scalable, and more secure compared to the monolithic and N-tier architectures. That is why containerized applications bring you to a whole new level:

Application, Infrastructure, and Software development evolution

OpenShift pushes these boundaries even further, allowing both software developers and operation teams to utilize powerful microservice architecture and the simplicity of OpenShift GUI and the additional features it brings to the table. OpenShift is where you can really...
