Factors Supporting the Wide Usage of Clusters

Some of the factors for why clusters have become an important constituent in present day information technology are:

  • Inexpensive, mass-market microprocessors and workstations have combined to form super computing facilities. Even the power of individual workstations is dramatically increasing with better processors.
  • Workstations and PCs are easy to assemble, integrate, and manage. They are cheap and readily available. They easily join the existing networks.
  • The 1990s saw a sudden spurt in standard high-speed communication technology. The Introduction of such standardized communication facilities such as Fiber Channel, ATM, SCI, and switched Gigabit Ethernet have raised bandwidth from 10 Mb/sec to hundreds of Mb/sec. Decreased latency and increased bandwidth have removed the communication bottlenecks between the cluster nodes.
  • Standardization of software tools like TCP/IP helped indirectly to create cluster software. Cluster software began to exploit the new network technologies and protocols as they were implemented.
  • The rise in mass market, high availability E-business and internet-based computing has become the way to go. High availability and scalability of computer systems is one of the main requirements for the modern business. Clusters are well positioned to answer these needs and requirements.
  • Clusters can be grown easily. If the workload increases, it is simple to add a node.
