gRPC Essentials: Protocol Buffers and HTTP/2 Explained
Explore how gRPC leverages Protocol Buffers and HTTP/2 to enable efficient, binary communication between clients and servers. Understand the benefits of Protobuf serialization over JSON and the role of HTTP/2 in enhancing performance for remote procedure calls. This lesson helps you grasp the core technologies behind gRPC and its operation flow.
We'll cover the following...
gRPC is a high-performance, open-source framework for building remote procedure call (RPC) applications. It uses the protocol buffers (Protobuf) data format for serializing structured data and provides efficient binary communication across different programming languages.
Use of HTTP/2
In gRPC, communication between a client and a server happens over a network connection, typically using HTTP/2 as the underlying protocol. When a client sends a request to a server, the request is sent as an HTTP/2 message to the server, and the server responds with an HTTP/2 message containing the response. So gRPC inherits all the benefits of HTTP/2.
