Lessons learned is a theory, or conclusion, based on evidence at a given time and describes what went wrong (as well as what went right) throughout the lifecycle of a project. Although it’s completed during the project closeout process, it should occur during the entire project lifecycle to ensure all information is captured and documented. Consequences of not having a project review of lessons learned are the increased likelihood of repeating actions that might have caused:

This vSphere Essentials white paper will give you a basic understanding of some of the concerns or planning points to consider as you get ready to deploy vSphere in your organization. This is a glimpse into some of the essential things to consider for implementing vSphere. This will focus on some of the basics that vSphere administrators run into when installing the latest features and not realizing they still have some older versions implemented.

This white paper has three main goals. The first is to generate a better understanding of the cloud in both the business and IT communities. The second is to describe the major components of vCloud and the virtual datacenters they provide. The third is help businesses visualize and understand how vClouds could be beneficial in addressing their specific IT needs.

Once an organization has categorized suppliers, one of the benefits that is quickly realized is an understanding of how supplier changes affect the buying organization and vice-versa. Changes are the modification, addition, or removal of something from the environment. The scope and scale of each change can be different. Change management covers everything from regular, low-risk, operational modifications all the way to significant organizational strategic shifts.

Resource Pools are often misunderstood, disliked, and untrusted by vSphere Administrators. However, resource pools can be very useful tools for administrators who want to configure resource management without having to individually configure each VM. This leads to the administrator’s desire to explore the proper usage of resource pools.
