Seminar paper from the year 2013 in the subject Computer Science - Commercial Information Technology, grade: 1.0, Otto-von-Guericke-University Magdeburg (Faculty of Computer Science), course: Recent Topics in Business Informatics, language: English, abstract: Energy efficiency has a rising importance throughout society. With the growth of large data centers, the energy consumption becomes centralized and nowadays takes a significant amount of the overall electricity consumption of a country. Load balancing algorithms are able to make an existing infrastructure more efficient without major drawbacks. This structured literature research presents the state of the art technology regarding the load balancing approach to make data centers more en-ergy efficient. The state of the art approaches are reviewed for techniques, im-provements and consideration of performance effects.
