Cloud Camp Milan 2K9 Telecom Italia: Where P2P?

Where P2P ? … over the clouds … into the clouds … aside the clouds? ,[object Object]

P2P Technology (a simple view) ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Excerpts from http://berkeleyclouds.blogspot.com/

P2P as a complementary technology for Cloud Computing ? ,[object Object],[object Object],[object Object],[object Object],[object Object],Excerpts from http://berkeleyclouds.blogspot.com/ App 1 App 2 … Appl m DISTRIBUTED APPLICATIONS Node 1 Node 2 … Node n DISTRIBUTED HASH TABLE put (H(key), value); get (H(key), data); H(Key) is a hashing function of the Key

Are Operators out of the emerging trend of the (Data) Service/Platform/Infrastructure as a Service ?

The Prevalent Paradigm For Services Is Client - Server ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Web Client (Browser) Web Client (Browser) Web Client (Browser) Internet Web Server http http http http

P2P Computing as a competitor of Client Server? Capacity (HD System) =  (b i , s i , f i , p i ) Where: b i = bandwidth of node i s i = storage of node i f i = files of node i p i = processing of node i Capacity (Centralized System) = {b S , s S , f S , p S } Where: b S = bandwidth of the Server System s S = storage of the Server System f S = files stored in the Sever System p S = processing in the Server System Optimization is a problem Optimization is a function of a business model
