Composable architecture, also known as modular or component-based architecture, is a method of designing and developing software systems by breaking them down into smaller, independent components that can be reused and combined to create complex applications. This approach allows organizations to overcome data and workflow silos by creating unified systems where all data is accessible and workflows are seamless, thanks to APIs. Key characteristics of composable architecture include independent components with well-defined interfaces, reusability, and the ability to develop and test components separately, improving development speed and efficiency. By leveraging APIs and microservices, organizations can build flexible, adaptable systems that can be easily modified to meet changing needs, enhancing the overall efficiency and maintainability of the software. Although implementing composable architecture can be complex, especially in large systems, its benefits in terms of speed, cost reduction, and scalability make it increasingly popular in the fast-paced business environment.
