In their eagerness to adopt the microservice architecture a lot of companies forgot that moving to this model of distributed computing comes with dangerous pitfalls. Networks become congested. Services are added, moved and scaled as traffic increases or failure occurs. Finally, we need to connect our front-ends to this ever moving group of services.The Netflix Open Source Software Center is a collection of Open-Source tools and libraries developed by Netflix to help them build the system they need to bring video stream to millions of users worldwide . In this presentation we will have a look at some of these libraries and discover how they solve problems that will occur when splitting your system into hundreds of microservices. Even if you do not adopt microservices, the OSS-tools discussed in this session can help you to make your software more resilient than it is today.
