About this ebook

In these days of shortened fiscal horizons and contracted time-to-market schedules, traditional approaches to capacity planning are often seen by management as tending to inflate their production schedules. Rather than giving up in the face of this kind of relentless pressure to get things done faster, Guerrilla Capacity Planning facilitates rapid forecasting of capacity requirements based on the opportunistic use of whatever performance data and tools are available in such a way that management insight is expanded but their schedules are not.

A key Guerrilla concept is tactical planning whereby short-range planning questions and projects are brought up in team meetings such that management is compelled to know the answer, and therefore buys into capacity planning without recognizing it as such. Once you have your "foot in the door", capacity planning methods can be refined in an iterative cycle of improvement called "The Wheel of Capacity Planning". Another unique Guerrilla tool is Virtual Load Testing, based on Dr. Gunther's "Universal Law of Computational Scaling", which provides a highly cost-effective method for assessing application scalability.

Ratings and reviews

This book outlines an alternative way of doing capacity planning (the "Guerrilla" way) vs the traditional (the "Gorilla" way) capacity planning process. The Guerrilla approach however, seems to be better suited for system administrators and other professionals related but not dedicated entirely to the capacity planning process. IT professionals that are challenged by their management to start dealing with capacity planning issues possibly due to adoption of management frameworks such as ITIL v3. Guerilla techniques focus on rapid response to capacity planning requests by tackling the burdens that planning for the future represent for system administrators and developers, imposed by IT managers. The book is very well written and I might say it's sort of fun to read, but as I mentioned before, it might not be suited for the old-school capacity professionals.
