What methods and strategies do you use when integrating different systems or components?

When integrating various systems or components, I usually use the following methods and strategies:

• API Integration: RESTful or SOAP services for data exchange.
• Messages and Queues: using message brokers (e.g., RabbitMQ, Kafka) for asynchronous communication.
• Common Data Format: JSON, XML, or serialization protocols (e.g., Protobuf) for standardizing exchange.
• Microservices Architecture: dividing functionality into independent services with clearly defined interfaces.
• Integration Testing: writing integration tests to verify component interactions.

In Java, I often use the Spring Framework to simplify the creation of REST APIs and integration with other systems.
