Almost all successful Microservices stories have the same secret. They never started as microservices. Instead, they started as a monolith that got too big and was broken up. Build a Monolith first, explore the system’s complexity and boundaries, and only start moving toward Microservices when you need their benefits. The keyword is modularity.

Practice Verified Codes and Commands:
1. Creating a Modular Monolith in .NET:
dotnet new sln -n ModularMonolith dotnet new webapi -n API dotnet new classlib -n Core dotnet new classlib -n Infrastructure dotnet sln add API dotnet sln add Core dotnet sln add Infrastructure dotnet add API reference Core dotnet add API reference Infrastructure
2. Dockerizing the Monolith:
docker build -t modularmonolith . docker run -d -p 8080:80 --name myapp modularmonolith
3. Breaking Monolith into Microservices:
dotnet new webapi -n UserService dotnet new webapi -n ProductService dotnet sln add UserService dotnet sln add ProductService
4. Kubernetes Deployment for Microservices:
kubectl create deployment user-service --image=user-service:latest kubectl expose deployment user-service --type=LoadBalancer --port=80 kubectl create deployment product-service --image=product-service:latest kubectl expose deployment product-service --type=LoadBalancer --port=80
What Undercode Say:
Building a monolith before transitioning to microservices is a proven strategy for managing complexity and ensuring scalability. Modularity is key to this approach, allowing you to break down the system into manageable components that can later be independently deployed as microservices.
In the context of .NET, creating a modular monolith involves structuring your solution into separate projects for the API, Core, and Infrastructure. This separation of concerns makes it easier to transition to microservices when the time is right. Dockerizing your monolith ensures that it can be easily deployed and scaled, while Kubernetes provides the orchestration needed to manage multiple microservices.
Linux commands like `docker build` and `docker run` are essential for containerizing your application, while `kubectl` commands help in deploying and managing your services in a Kubernetes cluster. Windows users can leverage PowerShell to achieve similar results, using commands like `docker-compose` for local development and `kubectl` for deployment.
For those looking to dive deeper into .NET and software architecture, resources like the provided URL offer valuable insights. Additionally, exploring Docker and Kubernetes documentation can provide further guidance on containerization and orchestration.
In conclusion, starting with a monolith and gradually transitioning to microservices is a practical approach that allows you to manage complexity and scale effectively. By focusing on modularity and leveraging tools like Docker and Kubernetes, you can build robust and scalable systems that meet the demands of modern software development.
