The first barrier that a new Linux user has to face is the overwhelming number of flavors that this operating system has. These flavors are commonly known as distros (from distribution), and to date there are more than three hundred active distros to choose from. So, how to choose one? You can choose the most popular at the moment, or take heed of what your friend says, but are you sure that this is the one that you need? Making the wrong decision on this matter is behind a good number of disappointments with this operating system. You need to choose the distro that is right for you and your needs. Introducing Linux Distros teaches you the pros and the cons of the most frequently used distros in order to find the one that is right for you. You will explore each distro step by step, so that you dont have to endure hours of web surfing, countless downloads, becoming confused by new concepts and, in the worst cases, reading complex and marathon installation guides. You will benefit from the authors long-term experience working with each distro hands on, enabling you to choose the best distro for your long-term needs. Linux offers us a wonderful open source alternative to proprietary software, and using Introducing Linux Distros you can decide how to best make it work for you.

Use Linux containers as an alternative virtualization technique to virtualize your operating system environment. This book will cover LXCs unmatched flexibility with virtualization and LXDs smooth user experience. Practical LXC and LXD begins by introducing you to Linux containers (LXC and LXD). You will then go through use cases based on LXC and LXD. Next, you will see the internal workings of LXC and LXD by considering the repositories and templates used. You will then learn how to integrate LXC and LXD with common virtualization and orchestration tools such as libvirt and SaltStack. Finally, you will dive into containerization and security. The book will explore some of the common problems in security and provide a case study on how containerization can help mitigate some of the operating system-level security issues in an IoT environment. What You Will Learn Get an introduction to Linux containers Discover the basics of LXC and LXD See use cases that can be solved with LXC and LXD - for developers, devops, and system administrators Master LXC and LXD repositories Use LXC and LXD with common virtualization and orchestration tools Consider a containerization and security in IoT case study Who This Book Is For The audience for this book should have basic knowledge of Linux and software development in general.
