Cloud computing is a term used in a generic fashion and means different things to different people. In general cloud computing consists of three categories. IaaS, PaaS and SaaS. Then there are variations within these as well. From the end users (businesses) perspective, cloud computing will remain just a technology hype till the business relevance for cloud computing solutions is identified. The end users need to discover business drivers that justify or make it imperative for them to adopt the cloud computing solutions towards achieving specific business goals. Most large enterprises are still unsure of the relevance of cloud computing for them due to lack of identification of such business drivers. Data security and lack of binding SLAs is often cited as the core reasons why large enterprises shy away from embracing cloud computing. While these factors remain critical decision influencers, these are by no means show stoppers. Cloud computing solutions have many flavours that in their existing form, are relevant to a large business today. What is missing is the process of identifying relevant business drivers, knowledge of the solutions available in the marker today, lack benchmark or reference data to validate a solution and the willingness to change towards adopting new business/operations model. A formal approach based on Enterprise Architecting Principles is required for selecting and implementing cloud computing solutions.

This presentation describes various architecture considerations that were used in developing a cloud computing management framework for implementing a private or hybrid cloud. The process used in identifying, selecting and implementing the solution is potentially a template that can be leveraged by large enterprises to adopt similar or otherwise cloud computing solutions.
