In the field of information technology, a distributed system is a model in which components located on networked computers communicate and coordinate their actions by passing messages. The message-passing communication model is a form of inter-process communication (IPC) in which the sending process sends a message without waiting for a reply and the receiving process receives the message and replies at a later time.
There are many benefits to using a distributed system, including improved reliability, scalability, and performance. In a distributed system, if one component fails, the others can continue to operate. This is because the components are independent and each has a copy of the data. Additionally, a distributed system can be scaled by adding more components. This is because the components can be added or removed without affecting the others. Finally, a distributed system can offer improved performance by distributing the processing load among the components.
Apache Cassandra is a free and open-source NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Cassandra offers robust support for clusters spanning multiple datacenters, with asynchronous masterless replication allowing low latency operations for all clients.
Cassandra's architecture provides for great scalability and availability. Data is replicated to multiple nodes for fault-tolerance and each node can handle requests for any part of the data. The system is designed to be highly available with no single point of failure and no single point of bottleneck.
Cassandra is a great choice for a distributed system because of its many benefits. It is highly available, scalable, and can handle a large amount of data. Additionally, Cassandra's architecture makes it easy to add new nodes to the system.
