What is the fault tolerance api that provided by Netflix that will be widely used?
Netflix has released Hystrix, a library designed to control points of access to remote systems, services and 3rd party libraries, providing greater tolerance of latency and failure.
Why we use Hystrix?
The Hystrix framework library helps to control the interaction between services by providing fault tolerance and latency tolerance. It improves overall resilience of the system by isolating the failing services and stopping the cascading effect of failures.
How does Netflix hystrix work?
Hystrix is a latency and fault tolerance library designed to isolate points of access to remote systems, services and 3rd party libraries, stop cascading failure and enable resilience in complex distributed systems where failure is inevitable.
How Netflix uses chaos engineering?
Experiments with chaos monkey enable engineers at Netflix to build recovery mechanisms into their architecture. This means that when the tested scenario occurs in real life, components in the system can rely on automated processes to resume operation as quickly as possible.
How does Netflix do testing?
Real-Time allocations provide analysts with the ability to configure rules which are evaluated as the user interacts with Netflix. Eligible users are allocated to the test in real-time if they meet the criteria specified in the rules and are not currently in a conflicting test.
What is Ribbon Netflix?
Netflix Ribbon is a Part of Netflix Open Source Software (Netflix OSS). It is a cloud library that provides the client-side load balancing. It automatically interacts with Netflix Service Discovery (Eureka) because it is a member of the Netflix family. The Ribbon mainly provides client-side load balancing algorithms.
What is Eureka Netflix?

What can I use instead of Hystrix?
Akka, Envoy, Istio, Zuul, and Polly are the most popular alternatives and competitors to Hystrix.
What is Chaos Monkey and why is it important for Netflix?
Chaos Monkey is a software tool that was developed by Netflix engineers to test the resiliency and recoverability of their Amazon Web Services (AWS). The software simulates failures of instances of services running within Auto Scaling Groups (ASG) by shutting down one or more of the virtual machines.
How Netflix does the A and B testing?
We split a random sample of Netflix members into two groups using random assignment. Group “A” receives the current product experience, while Group “B” receives some change that we think is an improvement to the Netflix experience. Here, Group “B” receives the “Upside Down” product experience.

What is Netflix ZUUL used for?
Zuul is an edge service that proxies requests to multiple backing services. It provides a unified “front door” to your system, which allows a browser, mobile app, or other user interface to consume services from multiple hosts without managing cross-origin resource sharing (CORS) and authentication for each one.
Is Netflix ribbon deprecated?
Spring Cloud Netflix Ribbon has been deprecated and is not included in the 2020.0. 0 release train. Spring Cloud LoadBalancer is the suggested alternative.
What is difference between ZUUL and Eureka?
Zuul acts as the API gateway, providing a uniform, single point of entry into the set of microservices, while Eureka is essentially used as a “meta data” transport. Each client application instance (read microservice) registers its instance information (location, port, etc.)
Does Netflix still use Eureka?
According to the Eureka wiki (https://github.com/Netflix/eureka/wiki), the Eureka 2.0 has been discontinued. The open source work on eureka 2.0 has been discontinued. The code base and artifacts that were released as part of the existing repository of work on the 2. x branch is considered use at your own risk.
