Cluster means groups. Here a group of Internet connected computers, storage devices, etc are linked together and work like a single computer. It provides Computational power through parallel processing. Its cost is less and used for scientific applications.
Advantages:
- Price-performance ratio: The performance is high and the cost is less.
- Availability: If one group of system fails the other group will do the work.
- Scalability: Computers can be easily added according to the workload increases.
