A Guide for Understanding Cloud Computing

  • A Webtorials State-of-the-Market Report
  • Jim Metzler, Cofounder, Webtorials Editorial/Analyst Division

The hyperbole-to-reality ratio that currently surrounds cloud computing is the biggest this ratio has been since the initial development of ATM. The main difference between these two ratios is that when ATM was first being discussed there were agreed to definitions as to what was meant by ATM. That is not the case with cloud computing.


This is the first of two closely-linked reports the goal of which is to reduce the hyperbole-to-reality ratio that currently surrounds cloud computing and hence enable IT organizations to rationally plan for its implementation and adoption. In order to achieve that goal, this report will:

  • Describe a set of characteristics that are typically associated with a cloud computing solution.
  • Define what is currently meant by private, public and hybrid cloud computing solutions and describe how those definitions are likely to change over time.
  • Identify the potential cost savings and other benefits that are associated with cloud computing.
  • Describe the three primary classes of public cloud computing: Software-as-a-Service, Infrastructure-as-a-Service, Platform-as-a-Service.
  • Provide multiple examples of each class of public cloud computing, along with representative pricing and service level agreements.
A companion report, Cloud Computing: A Reality Check & Guide to Risk Mitigation, is also available.

Cloud Computing is one of the most important issues facing the Enterprise today, and it’s also one of the least well-defined. Exactly what is cloud computing, and how does it affect you?

This is GREAT, extensive independent tutorial on Cloud Computing that defines what cloud computing is all about, the variations on cloud computing, and the benefits that are critical to you and your business. I consider this to be a critical, must-read document.
