Technology Monoliths • Completely Distributed APIS • APIs are interfaces which are exposed either internally and/or externally and have governance and management around it
- 8. 8 © 2017 Puneet Sachdev | All rights reserved Concept 1: Service Discovery through Netflix Eureka Concept 2: Circuit Breaker using Netflix Hystrix • Microservices applications have many moving parts and span across multiple boundaries • How to prevent a network or service failure from cascading to other services? 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?
