Overview of this book

VMware vSphere PowerCLI, a free extension to Microsoft Windows PowerShell, enables you to automate the management of a VMware vSphere or vCloud environment. This book will show you how to automate your tasks and make your job easier. Starting with an introduction to the basics of PowerCLI, the book will teach you how to manage your vSphere and vCloud infrastructure from the command line. To help you manage a vSphere host overall, you will learn how to manage vSphere ESXi hosts, host profiles, host services, host firewall, and deploy and upgrade ESXi hosts using Image Builder and Auto Deploy. The next chapter will not only teach you how to create datastore and datastore clusters, but you’ll also work with profile-driven and policy-based storage to manage your storage. To create a disaster recovery solution and retrieve information from vRealize Operations, you will learn how to use Site Recovery Manager and vRealize Operations respectively. Towards the end, you’ll see how to use the REST APIs from PowerShell to manage NSX and vRealize Automation and create patch baselines, scan hosts against the baselines for missing patches, and re-mediate hosts. By the end of the book, you will be capable of using the best tool to automate the management and configuration of VMware vSphere.

This ensures that your servers are available as much as possible.

VMware vSphere Distributed Resources Scheduler (DRS) provides initial placement of a virtual machine on an appropriate host during power on, automated load balancing to maximize performance and distribution of virtual machines across hosts to comply with affinity and anti-affinity rules.

To save power and money, Distributed Power Management (DPM) will consolidate your virtual machines on fewer hosts in your cluster and power down the unused hosts when not all of the resources are needed.

To use DRS or DPM, you need a VMware vSphere Enterprise Plus or vSphere with Operations Management Enterprise Plus license.
