Spring gRPC Server

Insecure gRPC communication between microservices.

Overview

There are 3 types of gRPC connections:

Insecure connection

The first one is insecure connection, which we’ve been using since the beginning of this course. In this connection, all data transferred between client and server is not encrypted.

• Grpc Server Code example
• Grpc Client Code example

Secured by server-side

The second type is connection secured by server-side TLS. In this case, all the data is encrypted, but only the server needs to provide its TLS certificate to the client. You can use this type of connection if the server does not care which client is calling its API.

• Grpc Client: Will be soon

Strongest type of connection secured by mutual TLS

The third and strongest type is connection secured by mutual TLS. We use it when the server also needs to verify who’s calling its services. So in this case, both client and server must provide their TLS certificates to the other.

• Grpc Client: Will be soon
