- Kubernetes, at the time of writing, is the mayor Container orchestrator in the market.
- Kubernetes is composed of the binaries that make up the cluster, and the logical objects called API objects.
- Kubernetes API objects are the logical objects managed by the orchestrator.
- We can run orchestrated containarized workloads.
- A container orchestrator is a tool in charge of managing our running containers and different tasks related to keeping our workloads highly available.
- A Pod is the smallest logical object of Kubernetes that encapsulates one or more containers in shared namespaces.
- A Deployment is a set of replicated Pods that are managed by the Kubernetes replication controllers.

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
