HTTP/2 & Protocol Buffers: The gRPC Foundation

Understand the two technologies that make gRPC fast: HTTP/2 transport and Protocol Buffers binary serialization.

What Powers gRPC

gRPC's speed comes from two pieces: HTTP/2 for transport and Protocol Buffers for serialization. Together they explain why it beats JSON-over-HTTP/1.1.

HTTP/1.1 Limits

HTTP/1.1 sends one request per connection at a time; pipelining is fragile and head-of-line blocking forces many connections. That's latency and overhead for chatty APIs.
