By: Jasmine Noel, Founder and Partner, Ptak, Noel & Associates Tuesday, May 13, 2008 In theory, computing capacity should be like water, if you need more just leave the tap running a little longer. All manner of virtualization, grid and attached processing technologies are being developed and deployed in an effort the make this theory a reality. Therefore it would be easy to assume that capacity management would not be an issue for SOA. Just deploy the services and SOA infrastructure on your tap water computing power with a few automation policies and capacity management ceases to be an issue. What a lovely fantasy. The real world, unfortunately, does not work that way. The combination of great software flexibility (SOA) and great capacity flexibility (tap water computing power) does not eliminate the work of capacity management and planning. It transforms the job description in two ways, it requires advanced analysis of capacity usage to be a near real time activity, and it requires c
