Ques 11. Explain the concept of 'Polyglot Persistence' in microservices.
Polyglot Persistence refers to the use of different database technologies within a microservices architecture based on the specific needs of each service.
Example:
Using a relational database for user management service and a NoSQL database for a product catalog service.
Ques 12. What is the role of a Service Registry in microservices architecture?
A Service Registry is a centralized directory that helps microservices discover and communicate with each other. It contains the location and metadata of available services.
Example:
Eureka, Consul, or ZooKeeper can be used as Service Registries in microservices.
Ques 13. Explain the concept of 'Event Sourcing' in microservices.
Event Sourcing is a pattern where the state of a system is determined by a sequence of events. Each event represents a state change and is stored in an event log.
Example:
Storing events like 'OrderPlaced' or 'PaymentReceived' to reconstruct the system's state.
Ques 14. What is the difference between stateless and stateful microservices?
Stateless microservices do not store any state between requests, while stateful microservices maintain state across multiple requests.
Example:
A shopping cart service might be stateful, while an authentication service could be stateless.
Ques 15. How does microservices architecture support continuous integration and continuous deployment (CI/CD)?
Microservices enable independent deployment, allowing teams to release and update services without affecting the entire application.
Example:
Using CI/CD pipelines to automate testing and deployment of individual microservices.
