The document encompasses a workshop on microservices, emphasizing their advantages over traditional Service-Oriented Architecture (SOA) by breaking applications into independent smaller units. It highlights Netflix's microservices stack, including tools like Eureka for service discovery, Hystrix for circuit breaking, and Zuul for proxying. The workshop includes hands-on demonstrations, showcasing the setup and management of microservices using various Netflix technologies.

Technology Monoliths • Completely Distributed APIS • APIs are interfaces which are exposed either internally and/or externally and have governance and management around it

Concept 3: Real time monitoring using Netflix Hystrix Dashboard • When things fail, it is extremely important to note what is failing • How to monitor in near real time many microservices? Concept 4: Load Balancing using Netflix Ribbon • Dumb pipes and smart endpoints. Where does this leave load balancing? Concept 5: Proxying using Netflix Zuul • With diverse traffic hitting microservices, how to get an ability to provide intelligent filters on requests • Microservices applications run in containerized/virtualized and cloud environments where their actual locations change dynamically • How does a client of a service discover the location?
