The process of connecting and synchronizing various cloud-based and on-premises systems, applications, and data to create a unified computing environment.

Cloud Integration

Cloud integration represents the comprehensive set of strategies, technologies, and practices used to connect different cloud services, applications, and data sources into a cohesive ecosystem. This fundamental aspect of modern enterprise architecture enables organizations to leverage the full potential of both cloud computing and their existing infrastructure.

Core Components

1. Integration Patterns

Point-to-Point: Direct connections between specific applications
Pub/Sub: Message Queue patterns for event-driven architectures
API-Led: Integration through well-defined API
IPaaS: Integration Platform as a Service solutions

2. Key Technologies
