What Do Flexible Technologies mean for Composable Commerce?
Composable Commerce solutions, unlike a single-core, full-stack commerce platforms, consist of a portfolio of smaller applications which may come from multiple vendors, but play nicely together through APIs and the orchestration layer that supports them.
The future is flexible. Composable commerce embraces modern architectural patterns for both the back end (MACH) and front end (JAMstack).
The MACH Advantage

Modular by nature, microservices allow you to compose your ideal commerce solution, or add capabilities to your legacy system through robust and well-defined APIs.

Robust, well-designed and mature APIs are flexible enough to support a variety of touchpoints and use cases, but not so granular that they’re overly complex or come with a steep learning curve.
