Microservices and Importance in application development

Question

Can anyone define micro services and where do we need it and comparison with other web service methods Also how can we deploy and communicate with each other services

Microservices is an architectural style that structures an application as a collection of small loosely coupled and independently deployable services. Each service is focused on a specific business capability and communicates with others through APIs (usually HTTP/REST or messaging queues). Microservices are particularly beneficial in the following scenarios: Complex Applications : When an application has multiple functionalities that can be developed deployed and scaled independently. Agility and Scalability : Teams can work on different services simultaneously enabling faster development cycles and easier scaling of specific components as needed. Different Technology Stacks : Microservices allow the use of different technologies and programming languages for different services making it easier to adopt new technologies. High Availability : If one service fails it doesn’t necessarily bring down the entire application improving overall reliability. Comparison with Other Web Service Methods Feature Microservices Monolithic Architecture SOA (Service-Oriented Architecture) Structure Composed of small independent services Single unified codebase Composed of services but may be larger than microservices Deployment Each service can be deployed independently Requires redeploying the entire application Services can be deployed independently but often have tight coupling Scalability Services can be scaled individually Scaling requires scaling the entire app Services can be scaled but often less flexible than microservices Communication Lightweight protocols (HTTP/REST messaging) In-process calls Can use various protocols often heavier than microservices Technology Diversity Supports multiple languages and technologies Typically uses a single technology stack Supports multiple technologies but often more rigid than microservices
