gRPC (Google Remote Procedure Call)

• Uses GET for fetching data POST for everything else
• PROS
  • functions are easy to add, and for lightweight payloads, you get great performance overall
  • ability to define any type of function makes it infinitely configurable.
  • Usage :
    • command APIs that send simple requests to remote systems
    • customer-specific APIs, which help manage internal microservices at scale with great speed
• CONS
  • it’s tightly coupled to the underlying system, which restricts its reusability in many cases.
  • no abstraction layer sitting between the API and the actual system functions | Security Concerns
