Mastering VMware vSphere 6.5

Overview of this book

VMware vSphere 6.5 provides a powerful, flexible and secure foundation for next-generation applications which helps you create an effective digital transformation. This book will be based on VMware vSphere 6.5 which empowers you to virtualize any complex application with ease. You’ll begin by getting an overview of all the products, solutions and features of the vSphere 6.5 suite, comparing the evolutions with the previous releases. Next ,you’ll design and plan a virtualization infrastructure to drive planning and performance analysis. Following this , you will be proceeding with workflow and installation of components. New network trends are also covered which will help you in optimally designing the vSphere environment. You will also learn the practices and procedures involved in configuring and managing virtual machines in a vSphere infrastructure. With vSphere 6.5, you’ll make use of significantly more powerful capabilities for patching, upgrading, and managing the configuration of the virtual environment. Next we’ll focus on specific availability and resiliency solutions in vSphere. Towards the end of the book you will get information on how to save your configuration, data and workload from your virtual infrastructure. By the end of the book you’ll learn about VMware vSphere 6.5 right from design to deployment and management.

Resource management

The number of VMs that can run on ESXi is not infinite and the optimization of the resources ensures best performance. As compared to the physical world, where each server is often equipped with more resources than it actually needs, in a virtualized environment, you can allocate suitable resources to a VM based on its role and function.

An FTP server, for example, doesn't need to be equipped with a dual processor and 6 GB of RAM because the resources will be underutilized. Allocating a suitable amount of RAM and a correct number of CPUs, you can obtain best performance, saving resources for other VMs. Understanding how to manage and reallocate resources is then a key point to avoid overcommitment of resources (more demand than available capacity) that can compromise the entire infrastructure functionality.
