Rafael Winterhalter - Tracing Distributed Microservices

With the ascent of distributed architecture, modern software increasingly unwinds into networks of micro(-service) components. While this approach to building software - if done correctly - can improve a system's maintainability and scalability, distributed applications also introduce challenges for operations. Where monolithic applications typically offered direct access to extensive monitoring dashbords, such easy overview is no longer available when a multitude of services is connected loosly on a network. But how to keep track of a system of such dynamic state? Distributed tracing is a method of connecting interaction of different services on a network. Collecting and processing such tracing information again allows for the observation of a distributed system in its entirety. This talk shares the presenter's insights gained by working on the JVM-support of distributed tracing for the APM tool Instana.
