The Four Tenets of Composable Commerce: Modular

According to Gartner, getting a composable company is the innovation strategy of top electronic organizations. Gartner believes”by 2023, organizations that have adopted a composable trade approach will outpace competition by 80 percent in rate of new feature implementation” And by 2024, the analyst firm predicts 30 percent of organizations will adopt modular structure (by adopting packed business capacities ) when constructing ecommerce applications.

Composable Commerce means moving away from the full-stack ecommerce platform, and prior to developing a best-of-breed solution from smaller,”Lego block” components. Ideal applications can be assembled in a fashion that supports specific business requirements and use cases. Because rarely does a full-stack, all-in-one application (whether licensed from a vendor) fully satisfy the particular needs of a business longterm, embracing Composable Commerce ensures that the current solution can stay in-step with tomorrow’s requirements.

The modularity of the Composable Commerce platform is important to encouraging more rapid delivery, faster time to market and improved customer experiences across all devices and touchpoints.

Which are packaged business capacities?

A term coined by analyst firm Gartner, packaged business capacities (PBCs) are the building blocks IT leaders use to create and compose new applications.

By definition, they are a”bounded collection of data schema and a set of services, APIs and event channels.” In practical terms, they are smaller applications built around clearly comprehended performance that keep their own data and business logic, rather than share a unified code base with each other (like monolithic applications).

As an Example, in ecommerce a suite of packaged business capabilities may include Cart, Checkout, Customers, Account Management, Catalog, Pricing, Promotions, Orders, Payments and Search.

Are PBCs exactly the same as microservices?

You may be thinking — PBCs look a fantastic deal like microservices! Today’s advancement and vendor community may refer to packaged business capabilities as microservices, and oftentimes they’re not wrong. Some microservices are PBCs, but not all PBCs are microservices. The essential differentiation is business ability, and the acid test is when a microservice is meant to deliver well-defined business capabilities, called such by users.

By means of example, a very granular microservice like an Address Verification API is a substantial area of the checkout process, but the Checkout encapsulates more functionality. The Checkout service is referred to as a packaged business ability, while Address Verification is a microservice, which (based on Gartner) needs only be a”tightly scoped, strongly encapsulated, loosely coupled, independently scalable application component.”

Since the saying microservices is common vernacular when talking to modular trade components, this Composable Commerce series uses PBCs and microservices interchangeably.

Key benefits of modular commerce applications

Loosely coupled

Unlike closely coupled monolithic platforms where every service shares the exact same codebase, loosely coupled services can be independently updated. New code can be transmitted in an agile way and debugged without full-system QA. If you’re building services in house, this allows you take advantage of DevOps and CI/CD (Continuous Integration/Continuous Delivery). If you’re using third party, vendor managed solutions, you don’t need to change any backend code, and you also gain from the vendor’s own ability to leverage DevOps and CI/CD to deliver updates faster than monolithic vendors.


Yet another advantage of loose coupling is the ability to integrate services closer to the experience layer or”mind” through APIs, as opposed to from the code itself. This supports faster time-to-delivery without incorporating technical debt to the platform. Innovation can be rolled out to new touchpoints and rolled back as cleanly.

Independently deployable

Not only can separate elements of a composable platform be swapped in and swapped out as essential, but they might also be applied to new experiences you construct.

Using a monolith, a new touchpoint such as mobile self-checkout, curbside pickup or voice-enabled chatbot have to be hardwired to the entire backend system (and often, the monolith simply can’t support what the ending experience requires). With modular applications, only the needed services’ APIs and logic are included.

Independence also supports powerful reuse across touchpoints. By means of example, the exact same Catalog service can power multiple storefronts into your business or partner network. Cart and checkout can be embedded into a vast choice of posts, apps and adventures. Inventory can be enlarged to backoffice systems and dedicated apps for sales reps and dealers. Logic and information can be shared and constantly maintained across touchpoints and channels, or configured with precision to unique needs.

Independently scalable

Since modular applications are independently deployed into a public cloud, they can scale independently — indefinitely. This presents an essential advantage over monolithic applications which can only scale up or down as a whole. With a composable application, a spike in demand for one component won’t slow or take down the entire app. Does this improve uptime and customer experience, it keeps hosting costs in check.

By means of example, if you roll out a new mobile self-checkout solution to 100 physical stores, demand for the attribute’s related services can surge, although other parts of your composable commerce platform remain steady. Or, in case you suddenly add a million new SKUs to your catalog with new attribute fields, complex pricing and discounting rules, Catalog and Pricing can scale accordingly, without having to scale Search, Cart, Checkout and Accounts.

Future-proofing trade technology

A composable trade application enables an organization to be flexible and adapt to business change quickly with less friction, and less danger introduced to the backend environment. Since”lego bricks” can be swapped in and swapped out for best-of-breed, a composable venture can stay perpetually modern without having to endure a rip-and-replace replatforming or full-stack upgrade ever again.
