This book, the vSphere SDK for Perl Programming Guide, provides information about writing and running VMware® vSphere SDK for Perl scripts on ESX/ESXi or vCenter Server systems. Because SDK subroutines allow you to manage vSphere hosts using vSphere API calls, a brief description of the server-side object model is included. This guide focuses on explaining how to access and modify server-side objects using the vSphere SDK for Perl and on discussing some programming techniques.
