Business Guide for Building Microservices in .NET

Table of contents

As a free, open-source development program available to all users online, .NET is by far one of the most widely used platforms in the world. Over the years, it has been used to develop games, websites, desktop applications, and mobile software – and for those hoping to utilize its features for professional purposes, we have compiled this business guide to help you to get to grips with the .NET process, its potential, and more.

What Are Microservices?

In the most general terms, a microservice is a type of functional tool used in back-end development services. It has a structural design that relies on loose, flexible services that co-exist to create programming relying on lightweight protocols in order to function. In even simpler terms, however, they are small, compressed pieces of coding that communicate in a simple way to perform key functions.

What is Microservices Architecture .NET?

As briefly mentioned above, the microservices architecture relies on individual or small packages of data that, instead of being united into one large piece of coding, are singular in nature and are capable of performing their own programming. Imagine the human body for a moment – we all have arms, legs, fingers, and toes that each perform their own function whilst remaining connected to the brain (which gives the orders).

The microservice architecture works in much the same way, but instead of the components or modules being permanently attached, they are free to operate within their own environment. Each has a select piece of coding that allows it to coincide with the coding of the other modules.

Types of microservices in .NET

Although microservices can be defined as numerous programs, the reality is that .NET development services can be categorized into one of two sections.

The first is referred to as Stateless Microservices, and these work by processing data instantaneously without being able to store it. This means that once the task that they were designed for has been performed, they retain no memory of what just happened.

The second is known as Stateful Microservices, and these are the polar opposite of the aforementioned category; being able to retain data and repeat a process as often as required based on programming.

When to Use Microservices?

One of the most convenient ways to use a microservice is when a particular function or activity within a business or organization needs to change the way that it does something without having to make major changes to the infrastructure of software. With microservices, newer and more effective protocols can be introduced that allow the functionality of the specific task to be modified in a way that doesn’t require other changes to the mainframe of a network to be altered, too.

Advantages of Using Microservices in .NET

A key benefit to using microservices is that they can be autonomous and co-exist with other pieces of software without infringing on their activities. They are also independent in nature, allowing them to be deployed wherever needed with minimal risk of incompatibility across the behavior of systems and software.

Also, multiple microservices can be scaled in size to suit, as well as being able to detect faults and isolate them easily. As microservices architecture is much easier to code, regardless of the programming language used, the text can be far more easily read and navigated. This makes it possible for teams to collaborate with ease as opposed to working with other larger platforms and features that are more demanding.

What strategy to choose when building microservices in .NET?

For ease of use, especially when new to using microservices architecture, one particular strategy stands heads and shoulders above the rest – and that’s Service Instance. By allowing the host pattern to be defined on a singular basis, it’s possible to ensure that only one microservice runs at any given time, making it easy to troubleshoot and beta test before diving in and implementing an entire set of microservices.

By following this strategy, you can test each microservice one at a time and focus on any incompatibility issues should they arise. This is one of the safest ways, and even experienced coders take full advantage of it.

Preparation for Building Microservices in .NET

Before building a microservice, it’s always a good idea to select a reliable .NET framework as well as a segregated workspace – just in case anything goes wrong during the coding process. .NET microservices are transferrable and widely compatible, so it’s always better to be safe than sorry.

Understanding the Business Requirements

No two businesses will be the same, so before developing a microservice, be sure to identify the key expectations and requirements for new features of the company in question. This could be your own or a client’s business.

Choosing the Right Architecture

From Spring Boot to GoMirko and Micronaut; there are a variety of architectures that make developing microservices fairly straightforward. Before deciding on one, take a look at reviews, customer satisfaction, and other data to ensure that you make the right decision.

Tools and Technologies for .Net Microservices

Two particularly popular tools for users and developers of a microservices architecture are Seneca and Fabric8. Both of these provide configuration management which is a key technology to look out for as it can make the development process easy to oversee whilst allowing beta testing to remain as secure as possible.

Designing Microservices in .NET

There are 8 main steps when developing microservices in a .NET framework:

  1. Introduction to the service being developed
  2. Installation of the SDK for .NET functionality
  3. Creation of the process or service
  4. Running or beta testing of the service
  5. Installation of a Docker hub
  6. Adding the correct MetaData to the Docker
  7. Creation of the Docker image file
  8. Running the image file and launching Docker containers

Implementing Microservices in .NET

By using ASP .NET Core, it’s straightforward to create the correct API features that go on to become microservices for businesses.

Setting Up the Development Environment

To develop microservices in .NET, you will need to set up your development environment. Using the Docker containers, a development environment can be created for the creation of microservices and their protocols. You can also use Visual Studio Code, which is a lightweight, cross-platform editor that supports .NET Core. If you choose to use Visual Studio, you will need to install the ASP.NET and web development workload.

Writing the Code

Once you have set up your development environment, you can start writing code for your microservices. In .NET, you can build microservices using ASP.NET Core, a lightweight, open-source framework for building web applications and APIs.

To create a new microservice, you can use the ASP.NET Core web application template, which includes everything you need to get started. You can create a new project using the .Net new command-line tool, or you can use the template built into Visual Studio.

Testing and Debugging

Testing and debugging various components are critical parts of the software development process. In .NET, you can use a variety of tools to test and debug your microservices.

To test your microservice architecture, you can use the built-in testing framework, which allows you to write unit tests and integration tests. You can also use tools such as Postman or Swagger to test your endpoints manually.

To debug your microservices, you can use Visual Studio’s built-in debugger or the dotnet watch command-line tool. The debugger allows you to step through your code and inspect variables in every microservice, while .Net watch automatically rebuilds and restarts your entire application when you make changes to your code.

Deploying Microservices in .NET

Before deploying a new microservice, always check for existing ones to avoid issues. Do this by taking a close look at the ASP .NET Core framework, and if any microservices are present, isolate or delete them pending the implementation of the newly created microservice.

Deployment Strategies

The following 5 deployment strategies can be used for the implementation of a microservice:

  1. Orchestrators
  2. Serverless Functions
  3. Multiple Machines and Processes
  4. Single Machine with Multiple Processes
  5. Container-Deployed Microservices

Automating Deployment

Automating deployment is critical to deploying microservices in .NET. Manual deployment can be error-prone and time-consuming. Automating deployment using tools like Octopus Deploy, Jenkins, or Azure DevOps can ensure a consistent, reliable deployment process.

You can use automated deployment tools to create deployment pipelines that include building, testing, and deploying microservices. These tools can also help with managing configuration files, ensuring that the right settings are applied to each environment.

Monitoring and Maintenance

Once your microservices are deployed, it’s crucial to monitor and maintain them to ensure they are performing optimally. You can use tools like Application Insights, New Relic, or Azure Monitor to monitor your microservices’ performance and availability of all the functionalities.

These tools can provide real-time metrics, alerts, and logs, which can help you identify and troubleshoot issues quickly. You can also use these tools to perform maintenance tasks like scaling up or down your microservices, applying patches or updates, or rotating credentials.

What Is the Cost of Microservices Architecture Development in .NET?

Generally speaking, the cost can vary from provider to provider, but a good ballpark figure would be between $5000 and $10000 depending on the workload, turnaround time, implementation of new features, and other key factors.
