S. Dustdar:
"Design by Units - A Novel Approach for Building Elastic Systems";
Keynote Lecture: 14th International Conference on Enterprise Information Systems (ICEIS) in conjunction with ENASE 2012, Wroclaw, Poland (invited); 2012-06-28 - 2012-07-01.

Systems are built by utilizing resources. Resources can include infrastructure such as compute power, storage space, and bandwidth, but also nontechnical resources such as the financial budget available or the human (expert) manpower needed to skillfully operate the system, make decisions, or perform human-based computing tasks. The elasticity of a system through virtualized resources is thus a fundamental requirement of Web-scale systems; in system design, those resources must receive careful consideration. In this talk I will discuss the main principles of elasticity and present a fresh look at this problem, and examine how to integrate people in the form of human-based computing and software services into one composite system, which can be modeled, programmed, and instantiated on a large scale in an elastic way.
