Now let’s go a bit deeper into the MACH architecture.

MACH Principles

We start with a look at what exactly MACH architecture is. As already mentioned, the MACH architecture model, defined as Microservices-based, API-first, Cloud-native, and Headless, is a modern framework enabling organizations to build systems that are fast, flexible, and capable of delivering a seamless customer experience (CX). This MACH architecture definition highlights its composable nature, allowing enterprises to shift away from rigid, monolithic platforms toward a scalable model.

In fact, Gartner predicts that by 2027, at least 60% of all new B2C and B2B digital commerce cloud-based solutions will follow the principles of MACH architecture.

Below, we break down these MACH principles to see how they help platforms succeed in the demands of modern commerce.

Microservices-based

Microservices architecture is about splitting a system into independent, specialized services focused on distinct functionality. This approach delivered significant benefits for a leading credit rating agency, whose financial insights platform was enhanced by Expert Soft.

In this project, microservices architecture advantages were fully realized, enhancing the client’s platform. Independent scalability allowed each service to meet specific demands, optimizing performance and resource use. System resilience improved as autonomous services minimized the impact of individual failures, ensuring stability across the ecosystem. Efficiency also surged, with seamless updates to individual services, accelerating development speed and reducing operational costs.

API-first

An API-first approach means APIs become the backbone of your platform, allowing maximum flexibility on the front-end development without impacting the back-end. This supports modular updates, real-time integrations, and scaling flexibility — all crucial features for any ecommerce system where change is a constant.

Cloud-native

Cloud-native applications leverage cloud infrastructure for scalability and adaptability, making them suitable for high-demand environments. Expert Soft delivers on this approach through technology expertise in SAP Commerce Cloud, a cloud-native SaaS solution. The platform allows us to build high-load applications that would dynamically respond to real-time demand. It assures a seamless, always-available experience for end-users and optimizes operational costs of the businesses out there.

Headless

In headless commerce architecture front-end and back-end system parts are decoupled, creating flexibility in interface development and content delivery to users. For example, one of the world’s top cosmetics brands was suffering from poor performance and a lack of scalability using the traditional architecture, which impacted both user experience and growth.

Expert Soft provided a solution by transitioning the brand to headless, which allows for faster site performance and improved responsiveness. The change enabled the organization to scale easily and handle high-traffic demands without a hitch.

All these principles make the MACH architecture, first introduced by the MACH Alliance, an attractive option for enterprises to build composable ecommerce platforms.

MACH Alliance

Founded in 2020, the MACH Alliance is a global consortium with a mission to champion open, flexible enterprise architectures in an ever-evolving digital landscape. Established by industry leaders, the alliance educates and supports companies transitioning from monolithic systems to composable frameworks built on MACH principles. So, what are the key improvements?

Monolith vs. MACH

While monolithic systems are traditionally reliable, the centralized structure tends to become restrictive, hindering scalability, agile updates, and cost-efficiency.

In contrast, MACH architecture is designed with flexibility and resilience in mind. It allows independent scaling of each component and thus independently updates with rapid, low-risk deployments that ensure infrastructure costs align with actual demand. Below, we present a comparative look at these architectures across essential operational dimensions.

Feature	Monolith	MACH
Scalability	Limited by a central, rigid structure	Scales independently with each modular component
Flexibility	Rigid; updates affect the entire system	Flexible; updates apply to individual components
Deployment	Slow, with a higher risk of downtime	Fast, safe deployments for each component
Cost efficiency	Higher costs due to fixed infrastructure	Higher initial investment but long-term cost savings through scalable, on-demand resources
Technology stack	Limited to a single technology stack; difficult to integrate new tools	Supports multiple tools and technologies, enabling a best-of-breed approach
Maintenance	Higher maintenance effort; tightly coupled components make updates complex	Lower maintenance; modular design simplifies updates and troubleshooting
Time to market	Slower due to lengthy deployment cycles	Faster; independent updates reduce time to launch new features

Having compared MACH with traditional monolithic systems in the table above, we’ve already highlighted its key advantages. What we need now is to dive deeper into the tangible business value MACH architecture delivers, helping organizations achieve sustained growth and agility.

Business Value of the MACH Approach

Here’s how MACH architecture supports enterprise growth and innovation.

Scalability

Thanks to headless and microservices principles, MACH allows independent scaling of individual components depending on demand, saving resources and reducing bottlenecks. Such flexibility ensures that all parts of the platform can scale up during traffic spikes without affecting other areas, so the overall performance is optimized.
Agility

With its decoupled services, MACH enables rapid updates, quicker feature rollouts, and swift responses to market changes — all of which are critical in fast-moving digital environments.
Resilience

MACH architecture guarantees minimal risks of total system failures, thanks to the independence of all components. Issues in one area remain isolated, maintaining service continuity and enhancing platform reliability, crucial for high-traffic applications.
Cost-effectiveness

MACH’s modular approach enables businesses to scale resources up or down as needed, preventing over-provisioning. This, in turn, ensures that infrastructure costs align with real-time demand, ultimately optimizing resource use and reducing expenses.
