Monolith vs Microservices in .NET Core 1. Monolithic Architecture Definition : A single, unified codebase where all modules (UI, business logic, data access) are part of one large application. Deployment : Deployed as a single unit (e.g., one .exe or .dll ). Scaling : Scales by cloning the entire application (vertical/horizontal scaling). Communication : Internal method calls (no network). Tech Stack : Typically limited to a single framework/runtime. Example in .NET Core : An ASP.NET Core MVC app with controllers, services, and EF Core all in the same project. Single database, one codebase, deployed to IIS/Kestrel. 2. Microservices Architecture Definition : A collection of small, independent services, each responsible for a specific business function. Deployment : Each service runs independently (often in Docker containers). Scaling : Scale individual services based on demand. Communication : Via APIs (REST, gRPC, message queues). ...

📚 DevOps in Action – Simple Example
Let’s take an example of a Node.js application using Jenkins and Docker for automation:
- Developer pushes code to GitHub
- Jenkins detects the push
- Jenkins runs unit tests
- If passed, Jenkins builds a Docker image
- The image is pushed to Docker Hub
- Jenkins deploys it to a Kubernetes cluster
