ELI5 — The Vibe Check
gRPC is like REST but on steroids and speaking a secret language only computers understand. Instead of readable JSON, it sends tiny binary messages that are way faster. It's mostly used when services need to talk to each other at lightning speed.
Real Talk
gRPC is a high-performance, open-source RPC framework developed by Google. It uses HTTP/2 for transport and Protocol Buffers for serialization, making it significantly faster and more efficient than REST/JSON. It supports bidirectional streaming and is popular in microservice architectures.
