Retry Pattern allows to automatically retry an operation if it fails.

▪ Ensure that a service is able to handle failures or temporary

unavailability of dependent services.

▪ Common use of the Retry pattern in microservices is to handle

temporary failures when calling a downstream service.

▪ I.e. shopping cart service that relies on a payment service to

process payments.

▪ If the payment service is temporarily unavailable due to a

network issue, the shopping cart service use the retry pattern to

automatically retry the payment request.

▪ Allow the microservice time to fix itself with self-correct, and

extend the back-off time before retrying the call.

▪ The back-off period should be exponentially incremental

withdrawal to allow sufficient correction time
