Lectures

In English Practical non-blocking microservices in Java 8

We will show how to write application in Java 8 that do not waste resources and which can maximize effective utilization of CPU/RAM. There will be presented comparison of blocking and non-blocking approach for I/O and application services. Based on microservices implementing simple business logic in security/cryptography/payments domain, we will demonstrate following aspects: * NIO at all edges of application * popular libraries that support NIO * single instance scalability * performance metrics (incl. throughput and latency) * resources utilization * code readability with CompletableFuture * application maintenance and debugging All above based on our experiences gathered during development of software platforms at Oberthur Technologies R&D Poland.
