Revolutionize Development: Asp.net Core Microservices Boost 40% Efficiency

Microservice architecture has recently experienced a transformative change within the software development industry.

While traditional monolithic architecture remains useful, its maintainability and scaling issues have led to problems for iterative app development efforts. Microservice architecture provides a more scalable, flexible, and maintainable approach.

This article will examine ASP.NET Core Microservice Architecture with particular architectural patterns attention to how Ocelot can integrate an API gateway.

We will explore microservice principles, contrast them against monolithic architectures, and demonstrate how, using ASP.NET Core, you can create basic microservice structures using API gateways.

Microservices: What Are They?

Microservices architecture provides an innovative method for developing applications ranging in scale, from tiny to massively scaled ones, by dismantling an application into its components using this approach.

Microservices allow functionalities to develop more modularly while all modules work harmoniously to complete specific targeted tasks compared to monolithic architecture, which aims to include all functionalities into one project/application.

Need of Microservice Development Framework

This software development architecture features greater modularity and lightweightness while being easily extensible for other apps, all the hallmarks of cloud-native app development.

This strategy should help speed up development in microservices based applications towards the cloud-native paradigm.

Modifying preexisting software features quickly facilitates high-quality development while making runtime issues easy to address after production core applications deployment.

Every good idea brings its challenges; microservices are no exception. We must manage them across multiple servers while managing and aligning data and databases they depend on to operate without interruptions.

Compare Monolithic and Microservice Architectures

Before discussing microservice architecture, let's first briefly cover monolithic dependency injection architecture - the typical method for developing applications.

A monolithic application includes:

• All its components work as one cohesive unit in this approach.
• Making its deployment of new versions or bug fixes complicated.
• Often leading to compromises or downtime as its scale expands.

While effective when developing small to midsize apps, monolithic entire applications often become inflexible as their scope grows beyond small applications or medium-sized websites.

Microservice Architecture takes an alternative approach: it separates an application into smaller independent pieces called microservices for development, deployment and scaling with greater flexibility and easier maintenance in mind.

Every microservice serves a distinct function while sharing databases, if applicable.

Monolithic applications combine all their business functions into one procedure. As a result, their various function update cycles become intertwined; even minor adjustments to one function could force an entire program to rewrite and rebuild in response.

Your application's functionality can be divided into numerous independently deployable services with microservices architecture, enabling you to develop, launch, and maintain each service independently.

In this post, we showed how to build a basic ASP.NET Core microservice, then ASP.NET core web covered how using an API gateway with our microservices can enforce security while offering one point of access for backend services in our next microservice architecture article.

Finally, our microservice-based program would come to fruition as we implemented interactions among services.

Microservice Architecture's Power in ASP.NET Core

Let's consider using ASP.NET Core to develop an e-commerce app. By taking the traditional monolithic approach, multiple projects, such as eCommerce and core.

Data Access would be combined into one large solution. While this provides some independent services code organization for the program, its tightly bound nature makes updating difficult without disrupting other areas.

The use of Microservice Architecture can create unique ASP.NET Core WebAPI projects for each of these components - Products, Customers and Orders - that all function autonomously both logically and physically, making deployment easy across servers with decoupled asp.net microservices providing increased scalability while decreasing updates' potential downtime risk.

Implementation of ASP.NET Core Microservices

In an ever-increasing and fast-moving world, more dependable and responsive software systems are essential as data volumes and internet usage grow project files simultaneously.

Unfortunately, monolithic architecture - often leading to expensive maintenance costs and increased downtime when upgrading existing monolithic software applications - cannot meet this need. Hence, Microservices Architecture was introduced for application development.

Previous software architecture included database calls, user interface design and all business functionalities in one package.

MVC works similarly to ASP.NET Webforms, consisting of individual projects with standard functionality.

Microservice architecture-based application development does have some downsides, however. Updating apps with new features or fixing technical issues as they grow larger becomes increasingly challenging to address this real-time API project problem effectively.

Furthermore, this approach makes agile development techniques and quicker response times possible. Now that we understand the fundamentals of microservice architecture let's put Implementation of ASP.NET Core Microservices into motion.

Step 1: Setting up Microservices

Before beginning, launch Visual Studio and create an ASP.NET Core Solution called "Microservices.WebApi." Create a "Microservices" folder inside this solution core framework for business requirements, and add both "Product.

Microservice" and "Customer. Microservice" projects - our microservices for managing operations related to our products and customers, respectively.

To keep things straightforward, we assume that Entity Framework Core has already been installed for data access while Swagger handles their microservice's CRUD operations.

Add an empty "Gateway.WebApi" project into the solution's root folder. Since nothing will reside within this Gateway, this project should remain empty.

Step 2: Ocelot API Gateway Introduction

Ocelot, an open-source API Gateway built for.NET/Core platforms, creates an effective separation between clients and microservices by unifying multiple design pattern development teams and microservices under one domain.

Receiving requests API controller from clients as a Gateway, it forwards these to relevant continuous deployment microservices. Install the Ocelot NuGet package into a project named Gateway.WebApi to get started using Ocelot.

Step 3: Establish Routes for Ocelot

Add an "ocelot.json" file in the root directory of the Gateway.WebApi project: this contains Ocelot configuration settings.

Ocelot API Gateway's routing rules can be configured using JSON configuration diagrammatic representation files provided in development approaches.

When client requests come through for microservices, manage them efficiently and direct client interactions by hiding away config file the intricacies of microservice architecture and streamlining client interactions.

Two routes have been established for "Product.Microservice" and another for "Customer.Microservice." Let's dive deeper into the "Product.Microservice" route configuration:

• DownstreamPathTemplate: When used, Ocelot will forward requests sent from well-defined API clients with paths starting gateway product directly to Product API implementation.

  Microservice is specified here by its path template.

• DownstreamScheme: This setting specifies which communication scheme individual services between downstream requests and Microservices should occur since HTTPS was set in this example.
• DownstreamHostAndPorts: Here, we specify details regarding modern web application "Product.Microservice"with clean architecture.

  In this instance, "Product.Microservice" operates at port 44337 of localhost to receive requests from API Gateway.

• UpstreamPathTemplate: Ocelot uses this setting to specify a path template for upstream requests made to an API Gateway by clients, known as upstream API application requests or upstream requestors.

  Ocelot maps client requests with paths like "/gateway/product" received at an API Gateway into its related microservice with paths like "Product.Microservice with Path '/api/product."

• UpstreamHttpMethod: This describes which HTTP methods can be used on this route; in particular, "Product.

  Microservice" accepts POST, PUT, and GET requests.

"Customer.Microservice" route configuration differs significantly, using unique architectural design paths and port numbers unique to "Customer.Microservice." Ocelot API Gateway can effectively manage client requests from various clients and direct them towards specific microservices while keeping those requesting information confidential about its architecture.

Step 4: Launch of Program

Assure there are no mistakes by building and launching the solution now. Use API Gateway to gain access to product-related endpoints via "localhost:44382/gateway/product." Likewise, go to "localhost:44382/gateway/customer" for Customer related endpoints.

In summary

As discussed previously, ASP.NET Core and API Gateway's Microservice Architecture provide an effective method for ASP.NET core development scalable and maintainable apps.

By breaking our application into smaller microservices using Ocelot API Gateway, we can achieve a clean separation between client and microservices, simplifying management and scaling.

It enables Ocelot API Gateway users to implement, expand or create microservices independently of each other; this approach makes Microservice Architecture ideal for creating contemporary apps; as you become adept with microservices, you may explore additional techniques such as load balancing, authorization or authentication that improve your microservice-based apps further.
