To know more about the difference between ASP.NET Core vs Node.js, let’s go through the following points.

3.1 Processing Models

Both Node.js and .NET Core have different processing models.

Node.js

Node.js is an asynchronous platform because it operates on a single thread and this quality enables its server to handle various requests simultaneously without blocking them. When the source code is getting executed in the main thread, Node.js spawns on other threads for performing other tasks. And this is the secret behind the lightweight and efficient solution that is loaded with data.

.NET Core

.NET Core is also an asynchronous technology. This means that ASP.NET Core can handle multiple requests from the thread pool with the help of a separate thread and each I/O cannot block the thread. And by being one the fastest web frameworks, .NET Core can even make asynchronous processing fast.

3.2 Scalability

Node.js

Node.js is a server-side JavaScript environment that is designed for distributed systems. It enables the creation of microservices-based software that has the capability to scale autonomously and this helps in keeping the application safe from falling apart. And as a single instance uses only one thread, the developers have to use external process control or Cluster module to load the cores of the server. Besides, one can also use a load balancer like AWS ELB/NGINX.

Because of the scalability and different tools that this technology has to offer, it has become more popular amongst businesses like Uber, eBay, Twitter, Netflix, and more.

.NET Core

On the other hand, ASP.NET Core is also known for its scalability. It is a technology that perfectly fits the microservices architecture. It enables the developers to create multi-threaded mobile applications and in this case loading a single server is easier than Node.js.
