Introduction to Worker Service

Worker Service is a feature of .NET that allows developers to create long-running background processes that can run independently of the main application. With the recent release of .NET 5, Microsoft has introduced a new feature called Worker Service in .NET Remote. This new feature allows developers to create remote services that can run on a different machine than the one hosting the main application. This opens up a world of new possibilities for building distributed systems that can scale and handle high loads.

What is Worker Service in .NET Remote?

Worker Service in .NET Remote is a new feature in .NET 5 that allows developers to create background services that run on a remote machine. This means that you can now create distributed applications that can run on multiple machines and communicate with each other over the network.

With Worker Service in .NET Remote, you can create a remote service that runs on a different machine than the one hosting the main application. This allows you to offload CPU-intensive tasks to a dedicated machine, freeing up resources on the main machine to handle other tasks. It also allows you to scale your application horizontally by adding more machines to handle increasing loads.

How does Worker Service in .NET Remote work?

Worker Service in .NET Remote uses the gRPC protocol to communicate between the main application and the remote service. gRPC is a high-performance, open-source remote procedure call (RPC) framework that can be used to build distributed systems. It uses Protocol Buffers as the data format for messages, which is a binary serialization format that is more compact and faster than JSON.

To create a remote service, you first need to define a gRPC service interface that specifies the methods that the remote service will expose. You then implement the service interface in a remote service class that runs on a different machine. You also need to create a gRPC client that can communicate with the remote service over the network.

Once you have created the remote service and the gRPC client, you can use the Worker Service framework to start the remote service as a background process. The remote service will then run independently of the main application, and you can communicate with it using the gRPC client.

What are the benefits of using Worker Service in .NET Remote?

Worker Service in .NET Remote offers several benefits for building distributed systems:

1. Scalability: By running background services on dedicated machines, you can scale your application horizontally to handle increasing loads.

2. Performance: Using gRPC as the communication protocol between the main application and the remote service offers better performance compared to traditional REST-based communication.

3. Separation of concerns: Separating background services from the main application makes it easier to manage and maintain the codebase.

4. Resiliency: By running background services on separate machines, you can ensure that your application remains resilient even if one of the machines fails.
