Continuous availability: from the shift paradigm to unmanned operation. Is it still a dream?

摘要

Since the beginning, the operational management of traditional data centers has been based on human intervention. The pervasiveness of the ICT services has brought the data centers to run operations continuously (24/7) and as a consequence there is an exponential increase of the ICT's complexity. As a matter of fact, nowadays, IT infrastructure requires a lot of hands-on maintenance. Reliance on human operators for managing data centers is the main obstacle for their evolution. This paper answers the following question: is it really possible to have an Autonomic Data Center?
