Hands-On Linux for Architects

By: Denis Salamanca, Esteban Flores

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

Chapter 4: Using GlusterFS on Cloud Infrastructure

  1. The storage locations used by GlusterFS to store actual data.
  2. The Z FileSytem, an advanced filesystem created by Sun Microsystems and later made open source.
  3. A ZFS storage pool.
  4. A disk used for read request, typically faster and lower latency than the disks used in the zpool.
  5. Normally through the Operating System’s package manager, such as yum.
  6. A pool of GlusterFS nodes that will participate in the same cluster.
  7. Gluster volume creates <Volume name> <Volume Type> <Number of nodes> <node and brick paths>.
  1. This setting controls how much memory will be used for caching.
  2. Adaptive Replacement Cache, this is ZFSs caching algorithm.
