System integration involves connecting different computing systems and software applications physically or functionally to act as a coordinated whole. The goal is to ensure that various components work together seamlessly to improve workflow efficiency and achieve optimal business performance.
Point-to-Point Integration: Direct connections between systems, typically used for simpler setups but can become complex with more systems.
Hub-and-Spoke Integration: Centralized approach where a central hub manages connections and data flow between systems, simplifying management and scalability.
Enterprise Service Bus (ESB): Middleware architecture that allows communication between disparate systems using a common communication bus.
API-Based Integration: Use of APIs to enable different applications to communicate with each other, providing flexibility and scalability.
Microservices Architecture: Decomposing applications into small, loosely coupled services that communicate over a network, often through APIs.
