gRPC is a modern RPC framework that is a popular alternative to WCF. gRPC is built on top of HTTP/2, which provides a number of advantages over WCF, including:
- Performance: gRPC is much more efficient than WCF, especially for long-running connections.
- Scalability: gRPC is designed to scale to large numbers of clients and servers.
- Security: gRPC supports a variety of security mechanisms, including TLS and authentication.
- Cross-platform: gRPC is platform-neutral and can be used with a variety of programming languages.
