Federated architecture is a pattern that unifies semi-autonomous applications, networks, or software systems, allowing them to operate independently while complying with shared standards and resources. This approach promotes autonomy and interoperability, enabling individual systems to solve specific challenges without having to handle every challenge themselves. Federated architecture can be applied in various domains, including government, technology, and enterprise settings, where decentralization and collaboration are essential. By adopting a federated architecture, businesses can benefit from standardized agreements and resources, allowing them to remain relatively lightweight while exchanging data and functionality as needed. This approach is particularly useful for large enterprises or systems that require complex applications, and it encompasses various frameworks and disciplines to guide architects in their approach to handling such systems.
