Chapter 2  Grid, Utility Computing and Clusters 

Data and Storage

At the same time, many grid software solution vendors are designing some kind of unifying software, which controls multiple data sources, and project a single data view for the application or user access.


In the recent past, we have witnessed a rapid growth in server-to-server and server-to-storage communication capability. 10GbEthernet and Inifniband technologies are becoming very common. With the availability of these high bandwidth and low latency communication channels, huge data is moved across the servers in the grid environment. Communication within the grid for the purpose of sending jobs and data required for those jobs is now faster. This facilitates the transfer of job execution to other machines in the grid. Bandwidth is a critical resource for effective communication and optimum functioning of grid.

Jobs and Applications

Even though we talk of applications and transactions, ultimately the application is executed in terms of jobs and sub-jobs. As the application execution is split into multiple jobs, those jobs can effectively be moved to different processing centers in the grid. In the grid environment, processing centers are the servers or processors. Thus, a grid application that is designed or organized as a collection of jobs is quite suitable for the grid environment. These jobs can suitably be scheduled and executed within the grid and take advantage of multiple processing resources.
