Exploring the world of microservices using gRPC with Asp.Net Core 3.0

by Soft2share.com

The gRPC is a multi-platform remote process call library or a framework. gRPC allows you to interact straight with the microservices just like the user would do with REST or SOAP. However, the major reason why people prefer gRPC over others is that its performance is much quicker.  Therefore, most of the times, it is used to synchronize the data between various microservices. Let’s understand this with an example. Say, a microservice X requires an operation and information return from the other microservice Y. In this case, the users can easily internally generate a call with gRPC between A and B. With this, the communication will be a lot faster. Basically, gRPC’s approach is quick and direct, as the queue generally takes plenty of time to get to B from A and then return.

The world of microservices

Microservices, as the name suggests, isn’t very small. Micro may not be a correct prefix for these services in terms of the size. But, it makes sense when we talk about different aspects like deployment, responsibility, team size, manageability, etc. Microservice is not a small service, rather, it is a small focus service, and the makers have to aim to make it a small focused service rather than a small service. Though it is also true that the aim of developing more small services to stick to the notion of microservices approach may have a lot of expenses and time requirements.

Benefits of using gRPC

gRPC is used extensively to develop microservices as it is very popular. It is nothing but a highly advanced, high performing and an extremely lightweight RPC framework. The use of gRPC enables the language-agnostic implementations simply because of the contract-first API development. All this is has been possible because of the Protocol Buffers. Additionally, tooling is also available for a host of different languages to produce very powerfully-typed servers and clients.

ASP.NET Core 3.0 for microservices using gRPC

ASP.NET Core 3 allows you to make the most of gRPC for developing microservices. It has a new template, which is added in it as gRPC Service. With the help of this template, the users would be able to develop the gRPC Service. And, they will be able to make superb client apps. The apps could have been used for the organization of the data in series for sending and receiving data from the client to the server.

When it comes to using gRPC in ASP.NET Core 3.0, the need for manual work has reduced as compared to earlier. The amalgamation of gRPC and ASP.NET Core 3.0 has been liked by the users as it offers many benefits. Additionally, each and every tooling is present in Visual Studio.

However, at the same time, you should consider applying the Single Responsibility Principle to the codebase. Not just that, you may even plan to apply it to the architecture. As a domain-focused design tells you to segregate business skills into autonomous restricted contexts. You would require very detailed segregation and the distinction between them. And, the bounded contexts ideally should never interfere with one another. At the same time, they should not have any dependencies related to code-sharing. With the help of gRPC, the .proto files could be easily shared between contexts. This can be done by delivering them as artifacts in an already built system. Basically, all the components seem to have a neater boundary. Also, it will even interact with one another with the help of a planned contract channel known-protocols.

gRPC makes use of protobuf as an Interface Design Language. If you want to work with gRPC service, you will have to acquire the knowledge related to the protobuf file. These files have 2 different parts. The first part used for defining the gRPC Service. Whereas, the second part of the file is used to describe the message which is being sent between the client and the server.

There is a lot of discussion happening around the development of microservices using gRPC with Asp.Net Core 3.0. There are tons of benefits of using gRPC with Asp.Net Core 3.0, and therefore, the Asp.net development services experts are readily adopting it. And, the future seems to be even brighter.
