Modern Software Architectures increasingly rely on the network for parts of applications to communicate with each other. In the minds of many software developers the network will never fail. But when L Peter Deutsch wrote the “Fallacies of Distributed Computing” paper back in 1994, he was probably never more right than today. One of the hardest things when designing and testing for distributed failures is that most issues such as slow networks and lost packets will only be found in production environments. In this talk we will show you how to deal with distributed dependencies. We’ll discuss setting and dealing with time-outs, connection monitoring, connection pooling, thread pools, queue sizes, and latency. Moreover we’ll cover a strategy for improving fault tolerance in distributed architectures. The topics covered are especially relevant if your application has a lot of dependencies that it communicates with over a network i.e. microservices. It is even more applicable if your application is deployed to an environment which is prone to failure on a regular basis e.g. a “cloud”.
