Building resilient .NET applications with Polly - Part 1

Starting today, we embark on a comprehensive series of articles that delve into the art of constructing robust C# applications using Polly. Our primary emphasis will be on the intricacies of implementing various strategies with a specific focus on their application in the realm of microservices architecture.

Microservices are an architectural style that structures a software application as a collection of small, independent, and loosely coupled services. In a microservices architecture, the application is broken down into a set of independently deployable services, each representing a specific business capability. These services can be developed, deployed, and scaled independently, allowing for greater flexibility, maintainability, and scalability.

Nevertheless, this emerging paradigm brings forth certain challenges, particularly in the realm of overseeing distributed architectures and formulating effective responses when one of the microservices encounters performance issues. Frequently, these scenarios are initially disregarded at the project's outset, occasionally overlooked even as the application transitions to production. They are then hastily addressed, often during urgent or late-night situations prompted by user complaints.

Throughout this series, we will explore the adept handling of such issues using a robust library specifically designed for these challenges. We will delve into the implementation of practical use cases in C# with Azure Functions, observing how they respond when confronted with problems. Enter Polly.
