How to improve resilience with retry policies
Introduction
In the fast-paced world of modern cloud applications, transient faults are not just an occasional nuisance—they are an unavoidable reality. These temporary disruptions can severely impact your application's reliability, leading to poor user experiences and potential revenue loss. However, there is a powerful solution at your disposal: retry policies. By implementing retry policies, you can automatically retry failed operations, transforming potential failures into successes and significantly enhancing your application's resilience. This proactive approach ensures that your application remains robust and dependable, even in the face of inevitable transient issues. Don't let temporary faults dictate your application's performance—embrace retry policies and fortify your system's reliability.
What is a Retry Policy?
A retry policy is a strategy that defines how and when to retry a failed operation. It can help mitigate transient faults by giving the operation another chance to succeed. Retry policies can be configured with various parameters such as the number of retries, delay between retries, and exponential backoff.
Using Polly for Retry Policies
Polly is a .NET resilience and transient-fault-handling library that allows developers to express retry policies in a fluent and thread-safe manner. Polly supports a wide range of policies including Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback.
