Questions and Answers

What is the primary role of a proxy in a service mesh?

  • Implement load balancing for backend servers
  • Mediate all inbound and outbound traffic for the service (correct)
  • Expose APIs for different software components
  • Deploy and scale services dynamically

In the context of microservices, what is the purpose of an API?

  • Manage load balancing for services
  • Ensure optimal resource utilization
  • Define how services interact with each other (correct)
  • Locate and communicate with different components

Why is service discovery essential in microservices architectures?

  • To enable services to discover and connect to each other automatically (correct)
  • To distribute incoming network traffic across multiple servers
  • To ensure optimal utilization of backend resources
  • To define the endpoints and data formats for services
