What Is Composable Architecture?

Composable architecture is a software and web development approach that uses discrete, separate, and decoupled components or modules. These components can be easily combined or "composed" with each other to create more complex functionalities. They can function independently but also work together seamlessly when integrated.

Composable architecture is like a collection of building blocks. You can rearrange, replace, or enhance these blocks to suit your changing business needs. This level of customization lets you shape and adjust your digital platforms to your specific requirements. It also helps you stay agile and adaptable in a dynamic market landscape.

With composable architecture, you can piece together different services (such as payment gateways, inventory management systems, and customer relationship management tools) to create a customized platform that meets your unique needs.

Composable architecture is often seen as the keystone of modern software design. It shows a complex but harmonious system where different software components are effortlessly intertwined.

Composable architecture lets you break down a system or software into smaller, independent pieces. Each piece does one thing or a few related things well. You can mix and match these pieces easily without messing up the whole system.

With composable architecture, you can put together different apps that work on their own into one system. You don't have to stick with one provider or settle for a bad solution. You have the power to create what you want. Nothing more, nothing less.

What Does Composable Architecture Do By Definition?

In the ever-evolving landscape of web development, the air is thick with buzzwords and terms that all seem to hint at the same meaning. Albeit blurry, this resembles the echoing of a significant shift ​​that is steadily distancing itself from the once-prevalent monolithic and tightly knitted architectures. Instead, the focus has pivoted towards introducing greater agility and flexibility to digital platforms that businesses are now in high need.

Why this exodus from monolithic systems? The challenges posed by these traditional architectures are plentiful. Consider the hurdles faced by marketing teams: whenever they wish to implement even minor website changes, they often find themselves waiting on development teams for deployment. 

Or imagine you wish to introduce a new personalized campaign targeting a specific demographic or try out a third-party tool you find useful or effective. In a monolithic setup, doing so turns into a daunting, time-consuming task. Updating or deploying features means deploying the entire application again. This can lead to longer deployment cycles and potential downtimes.

Finally, consider the efforts required to optimize performance; every tiny tweak on the website's front end invariably demands modifications on the back end. Monolithic architectures tightly couple their components. This means a change in one area can have ripple effects throughout the application. A performance issue in one component can affect the entire application.

There are many more scenarios in which monolithic architecture simply don’t follow the growing business needs. This rigidity not only elevates costs but also considerably extends the time required to mold the platform according to preferences.

This is where composable architecture strides in, presenting itself as the solution to these challenges. A composable architecture integrates various application services or modules to deliver a comprehensive software experience. Picture this: assembling the pieces of a jigsaw puzzle where every piece, although unique, seamlessly fits with the other to reveal the bigger picture. Each service or component in this architecture retains its functionality, yet it harmoniously collaborates with others.

In the following sections, we’ll dive deeper into composable architecture’s benefits and elaborate on the reasons.

Yet, before we tread further, the waters may still seem muddied with terms that sound deceptively alike. Microservices, headless solutions, MACH architecture, and Jamstack are all part of this new vocabulary. The differences are subtle. However, if you’re interested in getting to know them, let's venture into a deeper analysis of these terminologies to understand their distinct roles in this new era of web development.

What Is The Difference Between Composable Architecture And Microservices?

Composable architecture and microservices do share similarities, particularly in their modular approaches to design and development. However, they are somehow distinct concepts with slightly different purposes and principles.


Microservices revolve around decomposing an application into compact, independent services. These services operate on their own, interconnected via APIs.

Composable architecture

Composable architecture is more about orchestrating diverse, sometimes pre-existing components to establish a functional system.

Let’s dive in.

The components in a composable system can be large or small and might encompass functionalities that, in a microservices world, would be broken down further. For example, a single composable e-commerce platform might include a few features like payment processing, inventory management, etc., as individual composable units. On the other hand, typically, each microservice is more granular, focusing on doing one thing and doing it well.

Composable architecture often centers around a broader ecosystem where businesses might select from existing components in the market. It gives businesses flexibility in selecting which components to include in their system, often from a mix of third-party vendors and in-house solutions. Thanks to that, businesses assemble various software components to create a tailor-made system.

Microservices are more about the architectural approach of building an application from the ground up or decomposing a monolithic application into smaller services that run in their environments. They provide flexibility in that matter since each microservice can be developed, deployed, and scaled independently. Each service represents a specific business capability and communicates over a network, usually through RESTful APIs.

Composable Architecture vs Microservices

Composable architectures vs headless solutions

While both headless commerce and composable commerce champion flexibility and modularity in the digital space, they do so in subtly different ways.

Headless architecture

Headless commerce primarily refers to the decoupling of the front-end presentation layer from the back-end functionality, for example in e-commerce platforms. This separation allows businesses to deliver content or product data across various channels, such as web, mobile, or even IoT devices, without being tied to a specific front-end framework.

This means the front end and back end operate independently, typically communicating via APIs. Headless centers around enabling developers to build or choose their own front-end experience without being restricted by the limitations of their back-end system.

Composable architecture

On the other hand, composable commerce takes modularity a step further. It's not just about decoupling the front and back ends. Instead, it's about building a commerce system where every single component, be it product management, customer data, payments, or inventory, is independent and interoperable. These are often referred to as Packaged Business Capabilities (PBC).

With composable commerce, brands have the freedom to handpick each element of their system based on their unique requirements, allowing for a truly tailored solution. This approach ensures that businesses aren't locked into a specific tech stack but can adapt and evolve by swapping in or out components as their needs change.

While headless commerce emphasizes the independence of front end and back ends, composable commerce celebrates the autonomy of every single component in a system, providing businesses with unparalleled flexibility in constructing their ideal digital ecosystem.

Yet, they can be easily complementary. A business might employ a composable approach to select various components, one of which could be a headless CMS or a headless e-commerce platform. In this way, the modular nature of composable architecture can integrate with the decoupled benefits of headless systems. This amalgamation paves the way for a more agile and tailored user experience, catering to the nuanced needs of businesses.

Composable vs Headless

Key Components in Composable & Modular Systems: The MACH Architecture

MACH Architecture is another term used to describe the abovementioned shift towards greater modularity, flexibility, and agility. Let’s break the term first:

  • Microservices-based: Instead of a monolithic structure where everything is interwoven, MACH leverages microservices. Each microservice is a small, independent service that corresponds to a specific business function.

  • API-first: APIs (Application Programming Interfaces) take center stage. An API-first approach ensures that systems are built with integration in mind, making it easier to connect various software components or third-party services.

  • Cloud-native: MACH architectures are designed to run in the cloud from the outset. This approach benefits from cloud features like auto-scalability, resilience, and distributed running.

  • Headless: MACH applications separate the front end (what the user interacts with) from the back end (where data processing and storage take place). This allows for more flexible and custom user interfaces, as developers aren't tied to a particular front end.

While both MACH and composable architectures emphasize modularity, MACH is a specific set of architectural principles. It’s more prescriptive, defining a clear set of guidelines for building systems.

Composable architecture, on the other hand, is a broader concept focused on building systems from individual components that can be easily combined or replaced. It’s more about the philosophy of system design and could technically encompass MACH principles within its fold. In many real-world scenarios, you'll find that businesses might employ a MACH approach within the larger umbrella of a composable strategy.

MACH provides a clearer roadmap for companies looking to build with the defined principles, while composable architecture offers greater flexibility in how businesses can construct their systems. There’s even a not-for-profit organization founded, called The MACH Alliance, that advocates for better, more guided, and structured practical implementation of these foundational principles. The companies centered around The MACH Alliance lead and support other organizations that want to switch to more flexible systems.

Composable vs MACH Architecture

What Are Packaged Business Capabilities (PBC)?

We said earlier that composable architecture is about constructing an ecosystem using modular components that can be easily combined, reconfigured, or replaced. Packaged Business Capabilities, or PBCs, serve as these modular components, each one encapsulating a distinct business capability within the broader business (e.g.) e-commerce context. Overall, they play a pivotal role in this approach because, at a high level, PBCs deliver specific, well-defined business functionalities. Here’s why.

  • Modular and Standalone: Unlike traditional enterprise software that tries to be a one-size-fits-all solution, PBCs are designed to be specific and focused. Each PBC handles a distinct business function or process, functioning independently of other capabilities.

  • Business-Centric: PBCs are centered around business needs and processes rather than technical requirements. They encapsulate a specific capability, like inventory management or customer relationship management, and can be easily understood in business terms.

  • Interoperable: Even though Packaged Business Capabilities operate independently, they're designed to be easily integrated with other systems or PBCs. This is usually achieved through open standards and APIs, allowing businesses to build a coherent system from multiple PBCs.

  • Configurable and Customizable: PBCs can be tailored to fit the specific nuances and requirements of a business. They're designed to be configurable, allowing businesses to adapt the PBC to their needs without extensive custom coding.
