Motivation/Trends Web as a channel for mass social interaction and

collaboration User Generated Content (UGC)

– Information overload Large data volumes

– US American consume 34 GB per day (2009); mostly video Pay-per-use Computing

– Costs are based on consumption (CPU cycles, storage)– Not having to buy and configure new equipment– No software/hardware maintenance

Novel data processing systems

Summary Cloud computing comes in many shapes and sizes from

infrastructure, to middleware, to entire platforms– On-demand, elastic scalability, usage-metered

Cloud computing is a new operations delivery model– Driver of new data processing systems and technologies

Fast development of scalable multimedia services Focus on the applications logic

– The heavy lifting of scaling in the cloud services layer Application to different domains sharing similar needs Benefits of Cloud computing for multimedia systems What is reasonable to be in the Cloud?
