Making and keeping web applications fast is hard work, but also very rewarding and pays off very quickly with higher user satisfaction, increased usage and better conversions. In this presentation I'll talk about all the lessons I learned by working on application performance at ResearchGate: Why it is actually important, how you can convince your managers to invest time and money in it and what you have to do to measure and improve performance server and client side.

Even though you tested your application perfectly errors and bugs will still happen in production, especially if other services or databases go down or are under high load. Thus it is very important to see errors happing and to be able to react to them quickly. In this talk I'll introduce you to efficient ways for monitoring and logging for errors and show how you can handle them if they happen, covering deployment strategies, using intelligent circuit breakers and gracefully reducing functionality.

In a microservice architecture the communication between services often happens over HTTP or another TCP based protocol. Unfortunately this can increase latency and the likelyhood of errors and failures. In this talk I will introduce you too circuit breakers, a way to make a microservice oriented architecture more stable and fault-toleration.
