# gRPC and Protocol Buffers
> gRPC is an open-source, high-performance universal Remote Procedure Call (RPC) framework that allows a client application to directly call methods on a server application on a different machine as if it were a local object. It makes it easier to create distributed applications and services. Protocol Buffers (protobuf) are Google's open-source mechanism for serializing structured data, which gRPC uses by default as both its Interface Definition Language (IDL) and underlying message interchange format. They support multiple languages and environments for building robust, cross-platform systems.

## Buyer Intent Signals
Problems: Monolithic Architecture: Developing applications as a single, indivisible unit without breaking them down into distributed services. This avoids the need for inter-service communication frameworks lik
Solutions: what is grpc | grpc protocol buffers explained | how to use proto files | protocol buffers serialization | RESTful APIs with JSON: Building APIs using the REST architectural style with JSON as the data interchange format. While widely adopted, it typically offers less performance and strict type-checking c | Message Queues (e.g., Kafka, RabbitMQ): Utilizing asynchronous messaging systems for inter-service communication. These are often used in conjunction with RPC frameworks but can also serve as primary  | GraphQL APIs: Implementing data fetching and manipulation using GraphQL. This provides a flexible client-driven API but differs from gRPC's focus on defining strongly-typed service contracts and effic
