Reliability
Reliability in distributed systems means that the system can consistently provide its intended functionality, despite the occurrence of various failures and errors such as hardware failures, network issues, software bugs, and human errors. A reliable distributed system ensures that data and services are always available, accessible, and delivered promptly, even in the face of these challenges.
Reliability is a crucial aspect of distributed systems, which are composed of multiple interconnected nodes or components working together to achieve a common goal. Achieving reliability in distributed systems requires the implementation of various techniques, such as redundancy, fault tolerance, replication, load balancing, and error handling. These techniques help prevent, detect, and recover from failures, ensuring that the system remains operational and consistent in its behavior.
