Overview of this book

Over the past six years, hundreds of organizations have successfully implemented Infrastructure as a Service (IaaS) platforms based on OpenStack. The huge amount of investment from these organizations, including industry giants such as IBM and HP, as well as open source leaders, such as Red Hat, Canonical, and SUSE, has led analysts to label OpenStack as the most important open source technology since the Linux operating system. Due to its ambitious scope, OpenStack is a complex and fast-evolving open source project that requires a diverse skill set to design and implement it. OpenStack for Architects leads you through the major decision points that you'll face while architecting an OpenStack private cloud for your organization. This book will address the recent changes made in the latest OpenStack release i.e Queens, and will also deal with advanced concepts such as containerization, NVF, and security. At each point, the authors offer you advice based on the experience they've gained from designing and leading successful OpenStack projects in a wide range of industries. Each chapter also includes lab material that gives you a chance to install and configure the technologies used to build production-quality OpenStack clouds. Most importantly, the book focuses on ensuring that your OpenStack project meets the needs of your organization, which will guarantee a successful rollout.

What are containers?


Since the 1970's, there has been research on how to separate applications from the host systems that they run on. In 1979, Unix V7 introduced us to the chroot system call that isolated a root directory of a process and it's children to a separate location on the host's filesystem, thus protecting the underlying host from prying eyes or malicious intent. Since then, we've seen developments such as FreeBSD jails (2000), Linux vServers (2001), Sun Solaris Containers (2004), LXC (2008), Warden (2011), Google's Let Me Contain That For You, and Docker in 2013.

Although some of these technologies are still around, most of them were the basis for future developments in container technology. This technology allow developers to package an application with all the required libraries and dependencies it needs and ship it as one complete package. Much like many different manufactures do today with durable goods like furniture and other premanufactured and self-assembled goods.
