Modular architecture is a design principle in which a system is divided into self-contained components (modules) with well-defined interfaces between them. Each module can be developed, tested and deployed independently. The benefits are easier maintenance, reusability and the ability to replace individual parts without modifying the entire system. Modularity is a foundational principle in cloud-native architecture and microservicesArchitecture where an application is split into small, independent services that communicate via APIs. - and is central to TvimenningOld Norse meaning 'two bound together' - one who solves a task shoulder to shoulder with another.'s product design.
