Ali Ghodsi UC BerkeleyKTH alig atcsberkeleyedu 21813 Ali Ghodsi aligatcsberkeleyedu 2 Need of Distributed Abstractions Core of any distributed system is a set of distributed algorithms. Access to resources of various machines is done explicitly by Remote logging into the appropriate remote machine Transferring data from remote machines to local machines via the File Transfer Protocol FTP mechanism Tightly Coupled Distributed System g littlebig endian Concurrency an issue that was already present in an OS Means that we can scale the capacity of the system by adding more resources Examples of distributed systems Web Email DNS Peertopeer systems le sharing CDNs cycle sharing brPag Overview of .
