Hands-On Linux for Architects

Overview of this book

It is very important to understand the ?exibility of an infrastructure when designing an efficient environment. In this book, you will cover everything from Linux components and functionalities through to hardware and software support, which will help you to implement and tune effective Linux-based solutions. This book gets started with an overview of Linux design methodology. Next, you will focus on the core concepts of designing a solution. As you progress, you will gain insights into the kinds of decisions you need to make when deploying a high-performance solution using Gluster File System (GlusterFS). In the next set of chapters, the book will guide you through the technique of using Kubernetes as an orchestrator for deploying and managing containerized applications. In addition to this, you will learn how to apply and configure Kubernetes for your NGINX application. You’ll then learn how to implement an ELK stack, which is composed of Elasticsearch, Logstash, and Kibana. In the concluding chapters, you will focus on installing and configuring a Saltstack solution to manage different Linux distributions, and explore a variety of design best practices. By the end of this book, you will be well-versed with designing a high-performing computing environment for complex applications to run on. By the end of the book, you will have delved inside the most detailed technical conditions of designing a solution, and you will have also dissected every aspect in detail in order to implement and tune open source Linux-based solutions

Why choose GlusterFS?

Now that we understand the core concepts of SDS, storage clusters, and the differences between block, file, and object storage, we can go through some of the reasons why enterprise customers choose GlusterFS for their storage needs.

As previously stated, GlusterFS is an SDS, that is, a layer that sits on top of traditional local storage mount points, allowing the aggregation of storage space between multiple nodes into a single storage entity or a storage cluster. GlusterFS can run on shelf-commodity hardware to private, public, or hybrid clouds. Although its primary usage is file storage (NAS), several plugins allow it to be used as a backend for block storage through the gluster-block plugin and for object storage with the gluster-swift plugin.

Some of the main features that define GlusterFS are as follows:

  • Commodity hardware
  • Can be deployed on a private...
