M - Microservices
MACH architecture works like a modular system because of its self-contained microservices. Microservices are individual software components for executing specific business functions (e.g. search, CMS or check-out) that can be developed independently and also freely combined depending on current needs. In addition, the different business functions can be logically separated from one another so that they can be developed individually by dedicated teams.
A - API First
APIs connect different applications, systems, or services, guaranteeing fast and secure data transfer and therefore enabling the rapid integration of functionalities. In other words, APIs enable applications to talk and interact with each other. The advantage of these interfaces lies in the flexibility for system extensions and with that, the creation of a cross-channel digital experience. API-first development focuses on APIs instead of pre-built software solutions. API-first development ensures that ALL functions within the platform are accessible via the APIs.
C - Cloud-Native
With MACH architecture, the platform is not only stored in the cloud, but actually implemented directly within it, including the tools and services. This eliminates the need for a local server; the platform is in this way almost completely protected against failures and can easily be scaled as required.
H - Headless
A headless commerce platform is an e-Commerce solution in which the front-end (head) has been decoupled from the back-end commerce functions via APIs. Such an IT architecture enables microservices to be flexibly integrated via APIs, thereby quickly opening up new revenue opportunities. Since front-ends are decoupled from the business logic, new channels such as marketplaces or social media shopping can be implemented very easily.
