Application software development is continuously evolving, adding new techniques and more effective architectural patterns. Using microservices is one of the latest practices that have revolutionized application development. Microservices is an application architecture pattern that allows building mobile, web, and desktop applications with complex business logic that are easy to scale and modify. As a result, these applications are highly flexible and can easily adapt to their users’ expectations.
The most widespread framework used for building microservices is .NET. In this article, we will look into the specifics of microservices and explain why .NET would work best for building apps’ microservices architecture.
What Are Microservices and How Do They Work
Microservices Application Architecture derives from the principles of domain-driven design, continuous delivery and deployment (CI/CD), and automatization. It represents a set of separate small services each having its own logic and data domains. Each service can perform a particular task and use APIs for communicating with other services to accomplish more complex business tasks.
Microservices are independent components. It means that software developers can build, deploy, maintain, and delete each service independently without breaking the whole system. This autonomy gives apps with microservices architecture a considerable advantage over the apps with the monolithic models. Microservices architecture makes applications more stable, easier to debug, and cheaper to modify.
Major Components in a Microservices Architecture
Services are just some of the components in the microservices system. To maintain its container-based principle this type of architecture deploys some other components. Let’s have a look at the major ones.
- Identity Provider – provides validation and authentication services in a distributed network, managing the identity data.
- API Gateway – represents an entry point for the client that collects, sends, and returns responses from the microservices.
- Content Delivery Network (CDN) – services static resources, like page and web content in a distributed network.
- Static Content – contains all the static resources.
- Management – is responsible for the maintenance of the nodes for the service.
- Service Discovery – tracks services, their addresses, and endpoints.
When embedded into the microservices architecture, each microservice usually has its own database. Deployment of separate databases helps to prevent services’ intermingling into a single monolithic structure.
Benefits of Using .Net Microservices Application Architecture
There is a wide range of tools software developers can implement to build a microservices architecture. Though, one of the most broadly used is .NET. What’s so great about .NET for building microservices application architecture? Let’s clear that up.
The use of ASP.NET Core
ASP.NET Core is a web development .NET framework. It simplifies the creation of cross-platform microservices, their deployment to the cloud, and multiple operating systems.
Implementation of Docker containers
Docker helps to divide tasks into separate modules, making them lightweight and easy to deploy and maintain.
Compatibility with Kubernetes
Kubernetes is an open-source, extensible platform that allows managing containerized services and facilitates their configuring and automation. The platform provides an extensive range of tools that alleviate the scaling and deployment of microservices-based applications.
Cross-platform compatibility and multiple language support
ASP.NET Core runs on various operating systems, including Windows, Linux, and macOS, and supports various cross-platform technologies. While, .NET microservices are easily compatible with the apps written in other than C# programming languages, including Java, Node.js and others.
Migration to Cloud
Placing applications in the cloud enhances their services, security, and accessibility. Microservices-based apps built with ASP.NET Core can be easily hosted in Azure, a cloud platform from Microsoft. Azure provides total compatibility with all the .NET platforms as they are also developed and maintained by the Microsoft team.
Choice of IDE
For microservices development, ASP.NET Core provides software developers with the choice of IDEs. It means that they don’t have to work with Microsoft Visual Studio only but can pick up the tools they need to build the most effective microservices architectures.
Microservices Architecture Pros and Cons
The benefits and downsides of a microservices architecture derive from how it’s built and works. As this type of architecture is compiled from stand-alone services, the main aim of services development is to keep them loosely coupled. It means that they can be developed, deployed, and scaled independently from the system. The size of each service should be as small as possible. This helps to minimize the dependencies of microservices from each other.
All of these microservices aspects make them:
- simple to understand and maintain;
- easy to modify, update, and implement;
- reusable and scalable;
- independent from other services;
- software and hardware fails resistance (the system can automatically move microservices to a safe place called VMs);
- applicable for building complex and complicated architectures;
- working seamlessly with container-based technology;
- fast to release.
However, microservices architecture development specifics can also cause some challenges. Some of them are:
Although building stand-alone services is much simpler, uniting them in one system may be quite challenging. Therefore, expert developers often recommend starting with building a monolithic system and then divide it into microservices as the product grows.
Defining the boundaries
Each microservice should have the boundaries that make it an autonomous unit from the entire system. Therefore, software developers have to focus more on logical models and related data to identify the borders of each service.
As each microservice requires its own database, software developers have to understand how to retrieve the data from them and build an API Gateway to order data requests from the users.
Microservice architecture management
For successful architecture management, a software development team has to implement a DevOps culture. DevOps practices enhance agility and operational efficiency of microservice architectures, ensure more frequent applications’ releases, and their faster deployment and development with CI/CD concepts.
Choosing the right architecture is the key step that defines the further application development style. There is a wide range of architectures though one of the latest trends is to build them with microservices.
Microservices architectures are very attractive for software developers and their customers as they consist of integral parts that can be quickly adjusted to the business and end-user requirements. They can be used for building various application types with the most complex business logic. At the same time, this architecture is quite cost-effective and provides fast time-to-market.
The most popular technology for building microservices architecture is to use .NET development services. They allow building microservices-based apps in the short term while ensuring their security and effectiveness.
