Grpc vs rest api performance7/7/2023 ![]() Rpc GetAnimal (AnimalRequest) returns (Animal) The listing defines a method, GetAnimal() as well as two messages Animal and AnimalRequest. The following code depicts an example of the specification file animal.proto. In gRPC, the specification file utilizes the extension. It is based on the Remote Procedure Call (RPC) architecture, through which a source makes a call to a predefined procedure on the target, usually an endpoint.īoth the messages sent to a procedure and the procedure are defined in a specification file. The gRPC is meant to allow for fast, efficient communication between a source and target. Moreover, It expresses the API RPC model in an Interface Description Language (IDL), which simplifies the task to determine procedures remotely. It determines a service, establishes methods and the parameters to allow remote calls and types of return. The gRPC model enhances the data transmission speed between microservices. So, a high level of abstraction prevents the user from worrying about mapping the RPC concepts to HTTP. This technology follows the implementation of an RPC API that uses the HTTP 2.0 protocol, however, HTTP is not visible to the API Developer or the Server. GRPC (Google Remote Procedure Call) is an extension of the RCP architecture. ![]() Implementations that describe a RESTful resource only in terms of properties are considered RESTful. Generally, implementations of REST tend to focus more on the properties of a resource with little regard to RESTful behaviors. Similar to an object, a RESTful resource has behaviors and properties. You can think of a resource as an entity similar to an object used in object-oriented programming. ![]() Representational State Transfer (REST), is defined as an architectural style that leverages HTTP as the standard communication protocol for dealing with resources defined in an API. Most modern developers map APIs to the same HTTP protocol, regardless of the model used (RPC or REST). ![]() Nowadays, most developers working on the RCP projects also select a few ideas from HTTP while maintaining the RCP model. The client can access it through one of the following HTTP commands: GET, DELETE, POST, and PUT. The advantage of REST API is that you can provide any service that integrates the microservice applications to the client as a resource. The REST APIs deliver the backend data response to the clients via JSON or XML messaging format. The REST architectural model follows the HTTP protocol to generate APIs. A benefit of RPC is that it supports remote procedure calls in on-premises and distributed environments. Moreover, the RPC model allows a client to request a function in a specific format. These rules define the “ Calls” (requests) and their formats that a client can invoke to call methods that communicate and interact with a service. The RPC model like REST establishes rules for client-server interaction. The server responses to the client while the internal message that passes inside the servers are hidden. The client requests a message that RPC translates and sends to the server. The RPC model involves a client-server architecture to generate APIs.
