Every application communicating over a network must be resilient to transient failures.

These failures can occasionally self-correct. For instance, a service processing thousands of concurrent requests might implement an algorithm to temporarily reject new requests until the load decreases. An application attempting to access this service might initially fail to connect, but could succeed if it tries again later.

It's crucial to design systems to be resilient against such failures. This article will explore one method of achieving this: using Retries.

At W3Dev, we use this mechanism across our microservices to handle failures while still providing optimal service to our customers.

Let's begin by defining what we mean by failures.
