gRPC

gRPC is used for services to talk to each other fast and easy.

Example:

• You have an order service and a stock service.
• The order service says: “3 items were sold.”
• gRPC sends this message quickly and with less data.

Why use gRPC?

1. Fast – uses binary data, not JSON.
2. Efficient – sends smaller messages.
3. Good for microservices that talk to each other often.

gRPC is often used for synchronous communication between microservices.
