This document summarizes Mike Brevoort's presentation on cloud computing to the Colorado Springs Open Source Users Group on April 29, 2010. It discusses the evolution of cloud computing concepts including grid computing, distributed computing, and utility computing. It outlines cloud service models including SaaS, PaaS, and IaaS. Key companies in each area are mentioned like Amazon (AWS), Google App Engine, and Microsoft Azure. The presentation notes that cloud computing is an incremental evolution through concepts like virtualization, on-demand provisioning, and economies of scale rather than a revolution. It also discusses challenges around security, privacy, legal jurisdiction, and vendor lock-in.

- somewhat liken this to the creation of the JVM in the 90’s the JVM abstracted us from hardware, we didn’t have to allocate physical memory anymore It encapsulated memory management it encapsulated network communication this bootstrapping aloud you to be more productive - to write software faster and build upon a tried and true layers

- * Going to start with SaaS because it’s something we call can relate to * Software as a service has been around since the invention of web applications * Might argue that mainframe apps were Saas via terminal * still abstracted software from the user

- a) What security commitments are taken and are they sufficient to meet my company’s needs? b) Do the terms of use commit the cloud provider to keeping a user’s data secure, or even private, from other legitimate users of the service? c) Do you have the right to perform audits on the cloud provider’s policies and processes? d) What right does the cloud provider have to change those policies and processes?
- * A major concern with cloud computing is the difficulty of determining where data will be stored, and, thus, what courts have jurisdiction and what law governs the use and treatment of such data (i.e., local, state, federal, foreign, etc.)
- * Several standards body working on cloud standards * But the implementations are so very different in approach and implementation
- * Need a comprehensive understanding of each party’s intellectual property rights in the solution, the information stored, the hosted applications, and all developments that result out of the cloud computing arrangement.
