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.
Disadvantages Programmability issues:
- Different computers uses different software and hardware hence the issues.
- Problem in finding fault: Fault detection is very difficult
