Transcript

Any application that communicates with remote services and remote resources needs to be sensitive to transient faults. Applications that run in the cloud are especially vulnerable to transient faults. This is due to the nature of the environment including the inevitable random connectivity issue over the internet. As such, these types of transient faults will often be encountered. A transient fault is the momentary loss of network connectivity and the temporary unavailability of a service or application or even a time out of an application that arises as a result. That being said, such transient faults are generally self correcting. 

Transient faults can obviously impact the perceived availability of an application. Ensuring a cloud hosted application can operate reliably means it must be able to respond to transient faults in an elegant manner. The application needs to be able to detect a fault when it occurs. It then needs to determine if the fault is likely transient or if it's a more long lasting fault. In addition to being able to detect faults, and what type of faults they are, the application must also be capable of retrying the operation that it was attempting during the fault if it determines that the fault is in fact transient. It also must be able to keep track of the number of times the operation has been retried. Applications that elegantly handle transient faults must use appropriate strategies when attempting retries. A retry strategy will specify the number of times the application should retry, the delay between each attempted retry, and what actions to take after a failed retry attempt.
