REST GRPC
REST GRPC
REST and GRPC are two different architectural styles for API development.
REST works well in integrating microservices and TPA (Third Party Applications) with core systems, while gRPC is great for IoT (Internet of Things) systems requiring light message transmission, multiplexed stream applications, and mobile applications lacking browser support.
REST, which stands for Representational State Transfer, is generally the standard used in web development efforts. It uses HTTP communication protocol and is generally easy to develop. With REST, resources are described by their URL. REST uses HTTP specifications to implement getting resources, adding resources, modifying by replacing a resource, patching resources, and deleting resources. You can easily understand how the utilization of HTTP, protocols which have been around for decades, makes REST easier to implement and use. However, because REST responses send the data structure and data over the network it is bulky to use and comes with a performance cost.
A system which uses REST must meet several important criteria in their design:
​
-
A Uniform interface and underlying methods of the network protocol
-
Client-server based
-
Stateless operations
-
RESTful resource caching
-
A layered system of servers
-
Code on demand

GRPC was developed by Google initially, and is based on the Remote Procedure Call (RPC) architecture. gRPC promotes improved performance, standardized interactions and enabled microservices development predictable. It is primarily focused towards applications needing to process data quickly and continuously. It considered to be more difficult to implement than REST, but the benefits often outweigh the effort when it is needed.
Using gRPC a source makes a call to a defined procedure on the target. The procedure and the messages that are sent to a procedure are defined in a specification file. Ultimately, gRPC functions by sending and receiving these calls, and receiving the procedures response. By sending just the data over the server, the performance of communications is significantly improved.
