Grid Computing
Grid computing uses multiple computers that are often geographically dispersed but linked by networks to perform everyday tasks. It is typically run on a data grid, a collection of computers interacting directly to coordinate jobs. Grid computing is practical when multiple subject matter experts need to collaborate on a project but need to share data and computing resources in a single location right away. By banding together despite their geographical distance, distributed teams can pool resources and contribute to a more significant effort. This means that all computing resources are not required to work on the same specific task but can instead work on sub-tasks that contribute to the overall goal.
A typical grid computing network consists of three machine types:
Control node/server: A control node is a server or a group of servers that administers the entire network and maintains the record for resources in a network pool.
Provider/grid node: A provider or grid node is a computer contributing resources to the network resource pool.
User: A user refers to the computer that uses the resources on the network to complete the task.
How Does Grid Computing Work?
Grid computing runs specialized software on each data grid computer. The software manages the entire system, coordinating various tasks across the grid. The software assigns subtasks to each computer so they can work on their respective subtasks simultaneously. After completing subtasks, the results are gathered and aggregated to achieve an enormous task. Furthermore, the software enables each computer to communicate with the other computers via the network to share information about which subtasks each computer is performing and how to consolidate and deliver outputs.
What are the Essential Elements of Grid Computing?
A grid computing environment is made up of several primary grid components. Because grid designs and expected usage differ, specific components may or may not always be included in the grid network. Furthermore, these components can be combined in particular scenarios to form a hybrid component. However, the combination of elements may differ depending on the use case. Some grid computer elements are user interface, security, scheduler, data management, and workload and resource management.
Advantages of Grid Computing:
It is not centralized, as no servers are required, except the control node, which is just used for controlling and not for processing.
Multiple heterogeneous machines, i.e., machines with different Operating Systems, can use a single grid computing network.
Tasks can be performed parallelly across various physical locations, and the users do not have to pay for them (with money).
Disadvantages of Grid Computing:
The software of the grid is still in the involution stage.
A super-fast interconnect between computer resources requires an hour.
Licensing across many servers may make it prohibitive for some applications.
Many groups are reluctant to share resources.
What is the difference between Cloud Computing and Grid Computing?
Grid computing has benefited many industries, including information technology, automotive, aerospace, astronomy, physical sciences, life sciences, and media. Organizations can complete tasks much faster by distributing work across network nodes using grid computing, regardless of the geographical spread of the nodes. As grid computing evolves, more industries must determine how to best embrace it by developing versatile networks, accelerating business processes, and achieving overall success.
