- A service mesh works at which layer of the network?
A) Layer 7
B) Layer 3/4
- Libraries such as Hystrix and Finnagle were excellent in abstracting traffic routing capabilities, but why did Envoy prove to be successful for cloud-native applications?
A) The libraries were for Java applications, and they needed to be ported to other applications, whereas the Envoy proxy sidecar was language-agnostic and could work with polyglot applications.
B) An update in the library will force an application to update, whereas the Envoy proxy can be upgraded independently of the application microservices.
C) Libraries can manage traffic, but load balancing is an outside function, whereas it is integrated with the Envoy proxy with dynamic rules and configuration propagation through Istio components.
D) All of the above.
E) None of the above.
- The Istio control plane is a single point...
