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

  1. HIPAA stands for Health Insurance Portability and Accountability Act which is a standard for handling health and medical data.
  2. Type 1/ Type 2 Hypervisors (Kernel-based Virtual Machine (KVM), Linux containers (LXC), XEN)
    Linux for SAP HANA
    Apache Hadoop
    Linux for Oracle DB
    Large MongoDB deployments for memory caching
    High-performance computing (HPC)
  3. Yes, ideally hypervisors need access to the resources to more effectively provide them to virtual machines.
  4. Yes, CPU is the major resource being shared as the physical CPU has to serve cycles for all of the VMs in the same node.
  5. Allowing for different network traffic to go through different NICs/ Subnets.
  6. This is a method of migration which literally moves existing workloads from on-premises to the cloud.
  7. This is a method of migration which leverages some changes to the architecture to take advantage...
