Detailed explanation-1: -A single point of failure, also known as SPOF, is any component of a system that causes the whole system to stop working if it fails. When designing reliable systems, SPOFs can be avoided by implementing redundant components and replicating critical parts of the system.
Detailed explanation-2: -A single point of failure (SPOF) is essentially a flaw in the design, configuration, or implementation of a system, circuit, or component that poses a potential risk because it could lead to a situation in which just one malfunction or fault causes the whole system to stop working.
Detailed explanation-3: -Circuit Breaker Pattern If there are failures in your Microservice ecosystem, then you need to fail fast by opening the circuit. This ensures that no additional calls are made to the failing service, once the circuit breaker is open. So we return an exception immediately.
Detailed explanation-4: -Backup and redundant systems and software components ensure against the loss of a primary system. A second channel or conduit for redundant network cabling protects against loss of connections to local carriers and internet service providers. More items
