Building resilient .NET applications for the modern age
#1about 4 minutes
The high cost of ignoring system resilience
Most technology leaders are aware of resilience issues but fail to act, despite outages costing millions of dollars.
#2about 5 minutes
Understanding the key layers of application resilience
True resilience requires a multi-layered approach, considering infrastructure, architecture choices like microservices, and application-level communication patterns.
#3about 5 minutes
Introducing the Polly library for .NET resilience
The Polly library provides a fluent, thread-safe way to implement resilience strategies, avoiding manual and error-prone retry logic.
#4about 2 minutes
Implementing the retry pattern with exponential backoff
Configure the retry strategy to handle transient failures with exponential backoff and jitter to avoid creating traffic spikes.
#5about 3 minutes
Preventing cascading failures with the circuit breaker
Use the circuit breaker pattern to temporarily stop sending requests to a failing service, giving it time to recover.
#6about 2 minutes
Managing request throughput with the rate limiter
Control the number of concurrent requests sent to a downstream service using Polly's rate limiter to prevent overloads.
#7about 1 minute
Integrating Polly resilience patterns with HttpClient
Use Polly's extension methods to add resilience handlers directly to the HttpClient pipeline, separating resilience configuration from business logic.
#8about 2 minutes
Validating system robustness with chaos engineering
Intentionally inject failures, latency, and unexpected outcomes into your system using chaos engineering to test if your resilience strategies work as expected.
#9about 6 minutes
Simplifying setup with Microsoft's resilience extensions
The Microsoft.Extensions.Http.Resilience package provides a pre-configured, standard resilience pipeline for HttpClient, simplifying setup and promoting best practices.
