- It depends on the volume type used, but 2 CPUs and 4+GB of RAM is a good starting point.
- GlusterFS would use the brick’s filesystem cache mechanism.
- It is a fast storage layer where I/Os will be served instead of going to slower storage. Cache can be RAM or faster storage media, such as SSDs.
- As more concurrency is achieved, the software will require more CPU cycles to server the requests.
- Distributed will aggregate space, Replicated will mirror data, hence “halving” space, Dispersed will aggregate space but will consume 1 node for parity. Think of it as a RAID5.
- Depends on many variables such as retention periods, data ingress, etc...
- The expected amount of data growth.
- Throughput is a function of a given amount of data over a given amount of time, normally displayed as MB/s or Megabytes per second

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
