Difference between Cluster Computing and Grid Computing
Cluster Computing
A cluster computer refers to a network of same type of computers whose target is to work as a same unit. Such a network is used when a resource hungry task requires high computing power or memory. Two or more same types of computers are clubbed together to make a cluster and perform the task.
Grid Computing
Grid computing refers to a network of same or different types of computers whose target is to provide a environment where a task can be performed by multiple computers together on need basis. Each computer can work independently as well.
Following are the important differences between Cluster Computing and Grid Computing.
| Sr. No. | Key | Cluster Computing | Grid Computing |
|---|
| 1 | Computer Type | Nodes or computers has to be of same type, like same CPU, same OS. Cluster computing needs a homogeneous network. | Nodes or computers can be of same or different types. Grid computer can have homogeneous or heterogeneous network. |
| 2 | Task | Computers of Cluster Computing are dedicated to single task and they cannot be used to perform any other task. | Computers of Grid Computing can leverage the unused computing resources to do other tasks. |
|
| 3 | Location | Computers of Cluster computing are co-located and are connected by high speed network bus cables. | Computers of Grid Computing can be present at different locations and are usually connected by internet or a low speed network bus. |
| 4 | Topology | Cluster computing network is prepared using a centralized network topology. | Grid computing network is distributed and have a de-centralized network topology. |
| 5 | Task Scheduling | A centralized server controls the scheduling of tasks in cluster computing. | In Grid Computing, multiple servers can exist. Each node behaves independently without need of any centralized scheduling server. |
| 6 | Resource Manager | Cluster Computing network has a dedicated centralised resource manager, managing the resources of all the nodes connected. | In Grid Computing, each node is independently managing each own resources. |
| 7 | Autonomy | In Cluster computing network, whole system works as a unit. | In Grid computing network, each node is independent and can be taken down or can be up at any time without impacting other nodes. |
