Difference Bet. Clustered and Distributed systems?

Click For Summary
SUMMARY

The discussion clarifies that clustered systems are a specialized form of distributed systems characterized by tightly coupled computers, typically located in close proximity and connected via high-speed networks. An example of a clustered system is the Cray-built supercomputer at Oak Ridge National Labs, which utilizes multiple CPUs for large-scale computations in fields such as physics and finance. In contrast, distributed systems can operate across various locations and do not necessarily require high computational power, exemplified by point of sale systems that upload data to a central database simultaneously from multiple locations.

PREREQUISITES
  • Understanding of clustered systems and their architecture
  • Familiarity with distributed computing concepts
  • Knowledge of high-speed networking technologies
  • Basic principles of supercomputing and its applications
NEXT STEPS
  • Research the architecture of clustered systems and their applications in supercomputing
  • Explore distributed computing frameworks such as Apache Hadoop or Apache Spark
  • Learn about high-speed networking technologies used in clustered environments
  • Investigate real-world applications of distributed systems in retail and finance
USEFUL FOR

Software architects, systems engineers, and IT professionals interested in understanding the distinctions between clustered and distributed systems, as well as their respective applications in various industries.

Hi!

What the difference between Clustered systems and Distributed systems? Can any help in a few lines?

Thanks.

Cluster is a special case of distributed system. The defining feature of a cluster is tight coupling between computers in the system, which are, in case of a cluster, typically located next to each other and connected via high-speed network.
 
hamster143 is right. A cluster-based system is an example of distributing computing. Clusters can be many CPUs linked together in the same, single room. In fact, supercomputers are not always single monolithic machines anymore; the fastest supercomputer in the world is a Cray-built cluster located at Oak Ridge National Labs in Knoxville, Tennessee, USA. (While the term beowulf was once used to describe clusters, it is no longer in use.) Cluster-based systems are used for large computations for applications in physics, finance, engineering, and other compute-intensive areas.

However distributed computing can also be less compute-intensive, with no need for the speed of a supercomputer, and spread out over many different machines in many locales. If a point of sale machine at a restaurant needed to upload a customer order to a database stored on a central database while other machines across the country are doing the same thing at the same time, a distributed software program could accomplish this.
