2nd Week

    University of Sydney has a similar project of Cloud Computing, it is of Caas( Cache as a Service), which enables users to more “cost efficiently” deploy applications with heavy I/O activities on the cloud.* It utilizes the elastic cache system allows " enables users to dynamically rent the memory needed for your computing requirements". It is a new concept that CC works in a Hardware Independent Environment of which user has high flexibility of dynamical requirement---- just like " Pay as You Go" with out any "overheads".

    This week we communicated via emails, and the next step is quite clear. The time of figure out the infrastructure to set up the cluster is mainly considerable based on research on different ones. And the size of the server is now determined, so is the software is used**. Quite clearly, the main hardship in the coming next step is getting used to a new complicated software and setting up those machines.  

    Also, I am also considering a new service model, which we can call it "DBaaS"( Database as a Service). In this model, we may benefit much from it. Firstly, it will shrink the investment on hard disks and maintaining those. Secondly, it will level up the security. What is needy, is providing a entry,or called a port with special authorized password and grouped logging name, the database is set either in Read-only, Written or Limitted Inquiry***. Thirdly, it will broad spread the use of database--- not only requiring a computer of Dual Core to run a big database program sitting there, we can do it  with a cell phone or even a display device with network access and O/S devices. This, I think, would be somehow useful for those small enterprises, end-device users, home users(may enable the Playback features for TV).

** As mentioned, the software is Xen.
