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). ...
Absolutely, here's a list of interview questions related to microservices design patterns along with concise answers: 1.What are microservices? Answer: Microservices are an architectural approach where software is structured as a collection of loosely coupled services, each focused on a specific business function and independently deployable. 2.What is the purpose of using design patterns in microservices architecture? Answer: Design patterns provide proven solutions to common design problems. They help in creating scalable, maintainable, and robust microservices systems. 3.Explain the API Gateway pattern in microservices architecture. Answer: The API Gateway pattern acts as a single entry point for clients to access various microservices. It handles routing, authentication, and aggregation of responses. 4.How does the Circuit Breaker pattern work in microservices? Answer: The Circuit Breaker pattern prevents cascading failures by automatically detecting faults in a microservice an...
