Cluster Computing
- 1. Prepared by: Jyothi Venugopalan (QA Team Member) 5 th Jan 2012 BOSS Webtech Private Limited www.bosswebtech.com CLUSTER COMPUTING
- 2. Cluster computing is a form of computing in which a group of computers are linked together so that they can act like a single entity . It is the technique of linking two or more computers into a network (usually through a local area network) in order to take advantage of the parallel processing power of those computers.

- 5. High Availability Clusters Load-balancing Clusters High-performance Clusters TYPES OF COMPUTER CLUSTERS
- 6. TYPES OF COMPUTER CLUSTERS High-availability clusters are groups of computers that support server applications that can be reliably utilized . The clusters are designed to maintain redundant nodes that can act as backup systems in the event of failure. The minimum number of nodes in a HA cluster is two-one active and one redundant-though most HA clusters will use considerably more nodes . High Availability Clusters
- 8. Load balancing is a computer networking methodology to distribute workload across multiple computers or a computer clusters . Load-balancing clusters operate by routing all work through one or more load-balancing front-end nodes , which then distribute the workload efficiently between the remaining active nodes. Load-balancing clusters are extremely useful for those working with limited IT budgets . Devoting a few nodes to managing the workflow of a cluster ensures that limited processing power can be optimized. Load-balancing Clusters
- 10. High-performance Clusters High-performance computing uses supercomputers and computer clusters to solve advanced computation problems. HPC clusters are designed to exploit the parallel processing power of multiple nodes . They are most commonly used to perform functions that require nodes to communicate as they perform their tasks – for instance, when calculation results from one node will affect future results from another .
- 12. CLUSTER CLASSIFICATION Open Cluster All nodes can be seen from outside ,and hence they need m ore IPs , and cause more security concern .But they are more flexible and are used fo r internet/web/information server task . Close Cluster They hide most of the cluster behind the gateway node . Consequently they need less IP addresses and provide better security . They are g ood for computing task s.

- 16. BENEFITS Awesome Processing Power Cost Efficient Expandability Availability
- 17. 1 . Awesome Processing Power : The processing power of a high performance computer cluster is the same as a mainframe computer . With many computers in a cluster, the processing power may even exceed that of a mainframe . 2. Cost Efficient: Purchasing several good quality computers such as HP desktops at once, is less expensive than buying one supercomputer. The average PC today is a lot more powerful than the first mainframe computers. BENEFITS
- 18. 3 . Expandability : Many people feel that the best benefit of utilizing computer clusters is that they can be expanded easily by adding additional computers to the network. A mainframe computer has a fixed capacity and will only be able to handle so much power at a time. 4 . Availability: When a mainframe computer fails , the entire system fails . However, if a node in a computer cluster fails, its operations can be simply transferred to another node within the cluster, ensuring that there is no interruption in service . BENEFITS
- 19. Size Scalability (physical & application) Single System Image (look-and-feel of one system) Security and Encryption (clusters of clusters) Enhanced Availability (failure management) CHALLENGES
- 20. Cluster computing offers a, comparatively cheap , alternative to large server/mainframe computer solutions. Clusters based supercomputers can be seen everywhere. Offer incremental growth and matches with finding pattern. New trends in hardware and software technologies are likely to make clusters more promising. CONCLUSION
