Overview of this book

Computer virtualization is a method to enable the running of multiple application workloads on a machine to achieve efficient utilization and reduce the number of physical machines in a data center. This has now become the foundation of many modern day data centers. What began as a technology to virtualize x86 architecture has now grown beyond the limits of a server’s hardware and into the realm of storage and network virtualization. VMware is currently the market leader in developing data center virtualization solutions. This book goes into the details of designing and implementing VMware solutions that form the foundation of a VMware infrastructure. The book begins by introducing you to the concepts of server virtualization followed by the architecture of VMware’s hypervisor – ESXi and then by its installation and configuration. You then learn what is required to manage a vSphere environment and configure advanced management capabilities of vCenter. Next you are taken through topics on vSphere Networking, Storage, ESXi Clustering, Resource Management and Virtual Machine Management. You will then be introduced to SSL Certificate Management and its use in a vSphere environment. Finally, you will learn about the lifecycle management of a vSphere environment by effectively monitoring, patching and upgrading vSphere components using Update Manager. By the end of the book, you will know how to use VMware’s vSphere suite of components to lay the foundation of a modern day virtual infrastructure.

Preface

Laying the foundation for a vCenter deployment


VMware vCenter can be deployed as a Linux-based appliance or it can be installed on a machine running a supported version of Microsoft Windows. There are no real capacity or performance differentiators between both the deployment types. However, the Linux-based vCenter appliance does not support the use of an external Microsoft SQL database, owing to the fact that there are no supported Microsoft SQL drivers for Linux yet.

There is always a reason behind why an architect would choose either of the two deployment methods. Here, we will try to visit some of those aspects first before we delve deeper into the possible deployment models.

vCenter Appliance versus vCenter on Windows

We have categorized the design decisions into the following five categories:

  • Ease of deployment

  • Server management

  • Choice of database

  • Backup and recovery

  • Cost of licensing

Ease of deployment

The vCenter Server Appliance (VCSA) comes packaged with all the services required for the...
