Difference between Composable Commerce, Headless Commerce, and Traditional Commerce.
Traditional commerce, as it was a couple of decades ago, offered monolithic architectures as the only option for e-commerce companies. Monolithic software is one big codebase, meaning the functionality and customer-facing parts are tightly connected and all served in one place. In a monolithic platform, the software is built as a single, indivisible unit. Companies had no choice but to build and constantly update and maintain these increasingly complicated structures.
In a way, monoliths would seem to be simpler. All the necessary components are contained in one system. However, as time passed, many brands experienced challenges and problems with these all-in-one structures.
Monolithic platforms work by definition with tightly coupled front-end and back-end systems. In order to update them, developers must modify the underlying database code and the front-end platform. This can be very time-consuming. As a consequence, any update necessary can slow down the cycle and make it more difficult for companies to make quick updates and offer the latest solutions to their customers. Moreover, since the parts are coupled and dependent on each other, whenever one piece of the puzzle doesn’t fit, it can bring down the entire system.
