Retry Pattern

Transient exceptions are a common occurance in the cloud based applications. Most of these temporary faults are self-healing and could succeed when triggered with a slight delay. Some of the common transient errors include momentary loss of connectivity to services, a busy database server that throttle requests to ease off workloads. Ideally an application which … Continue reading Retry Pattern

Circuit Breaker with Ocelot & Polly – Part 2

In the previous blog post on Circuit Breaker with Ocelot And Polly, we saw how we could use the Ocelot library's inbuilt support for Polly to build Circuit breakers for handling timeout errors from the downstream services. In this blog post, we will address, how we could trigger a circuit breaker when the downstream service returns … Continue reading Circuit Breaker with Ocelot & Polly – Part 2

Circuit Breaker with Ocelot & Polly – Part 1

One of the key features of Microservices is the resilience to failures. In this blog post, we will aim to implement Circuit Breaker Pattern in our API Gateway. We would be using the Quality of Service (QoS) functionality exposed by Ocelot. Internally, Ocelot uses Polly library to implement Circuit Breaker. Timeout Failures from Downstream services As the first step, … Continue reading Circuit Breaker with Ocelot & Polly – Part 1
