.NET Application Architecture

By developing your solution with .NET, you can opt for traditional multitier architecture. This is a good choice for mid-sized projects, ensuring fast delivery, easy testing, and maintenance. Invest in cloud-native architecture if you need to ensure that your app is scalable while maintaining low operational costs.

Another option, which also allows you to create a highly scalable application using independently deployable services, is a microservices architecture. You can think of microservices as building blocks of your application. You can tweak, scale, and deploy them independently to fit your changing needs.

ASP.NET, Microsoft’s web framework for .NET, makes developing and deploying microservices easy. You can also use .NET with Docker, achieving outstanding performance.

When to Choose .NET?

First, choosing .NET for your application development will ensure faster delivery, using Language Integrated Query (LINQ), asynchronous programming, libraries, APIs, and powerful Visual Studio.

Invest in .NET application development services whether you want to build a web or mobile application, considering performance a priority. Choosing .NET will also improve your product’s security and scalability. This way, you can start your project with minimum resources and grow it to an extensive ecosystem over time.

Some companies using .NET are Stack Overflow, UPS, GoDaddy, Tencent, and Power BI.

The Cost of .NET Application Development

.NET is a free, open-source platform. Developing your software using .NET will require hiring software developers, whether by building your in-house team or investing in software outsourcing. The latter’s cost will depend on the scope of your project and the hourly rates of the software development company you choose.

.NET projects may include building a mobile or web app, IoT solution, Big Data, Machine Learning, gaming, and more. In such cases, the cost of developing your project will be similar to custom software development.

Other projects may include data migration and implementation of—NET-based solutions or integrations with third-party services. Again, the estimate will depend on developers’ time on each task and their hourly rates.
