The shift away from monolithic architecture is no longer a question of if. It’s a matter of how fast you can move.
You’re likely already weighing options to restructure your current stack into something more modular, faster to deploy, and easier to scale across regions. That’s where composable commerce built on AWS comes in.
But execution isn’t about theory. It depends on how well your partners understand real-world constraints, from backend performance to seamless integration with legacy systems.
In this article, you’ll compare top consultants, see where they differ, and get clarity on who’s best equipped to support your AWS roadmap. Let’s start by defining what these services actually involve.
Composable commerce consulting services on AWS help you build and manage a modular architecture using MACH principles. MACH is an acronym for microservices architecture, API-first approach, cloud-native, and headless.
In practice, these consulting services help you with technical planning, setting up APIs, provisioning cloud-native infrastructure, and tuning performance. Consultants also help you integrate services like order management systems, CMS, or payment gateways through scalable APIs.
With benefits like faster rollouts and cleaner integrations, it’s no surprise that composable commerce adoption is accelerating.
In fact, a Composable Commerce Trends 2025 report by Alokai shows that composable commerce has reached a 41.67% adoption rate, which proves it’s now a standard move.
When these services are implemented well, you get faster rollouts, cleaner integrations, and freedom from outdated platform constraints. If you like to learn visually, here’s an interesting YouTube video from John Williams, a CTO with over 25 years of experience in the tech industry:
Now, let’s look at why you need this now.
You need composable commerce consulting on AWS to support a scalable setup that adapts to growth and shifting priorities.
As a CTO or digital leader, you’re expected to deliver agility without increasing overhead, and that’s hard to do on monolithic platforms.
These are the advantages that matter most:
Pro tip: Composable commerce is one part of the puzzle. Here’s how top retailers tie architecture to broader transformation goals.
Next, let’s look at the consultants who specialize in delivering these results.
If you’re looking to adopt or expand a composable commerce architecture on AWS, the right partner can accelerate your progress. These are the top consultants helping teams build with confidence.

Elastic Path is a SaaS-based headless commerce provider that delivers a composable, MACH-aligned platform through AWS Marketplace. It’s known for early leadership in modular commerce and tools like Composer, a no-code integration hub, and Composable Frontend, a pre-built UI kit.
The company helps teams orchestrate APIs, services, and storefronts with fewer integration risks. It supports high-scale brands through multi-model support like B2B2C and multi-brand commerce.
However, the platform requires skilled developers for implementation and ongoing operations. This makes it less approachable for non-technical teams or companies looking for plug-and-play simplicity.

Grid Dynamics offers MACH accelerators built to speed up composable commerce on AWS. Its Starter Kit provides reference architecture, microservices templates, and pre-built connectors for services like Contentstack, Algolia, and Stripe. The kit also includes a headless storefront and deployment scripts.
The firm focuses on fast rollout and iterative deployment using agile methods. Its delivery model leans heavily on staff augmentation. This means you’ll manage projects internally while its engineers support execution.
That works well if you have strong internal leadership and need to scale quickly. But if you’re looking for a fully managed service with strategic input, this model may not match your needs.

McKenna Consultants is a boutique UK-based firm focused on cloud-native, composable builds for complex B2B commerce. Its strength lies in modernizing legacy ERP or PIM systems with API-first architectures that avoid full rewrites.
The company usually implements Elastic Path as the commerce engine, building around it with AWS-native components and custom services. This makes its solutions practical for enterprises with existing infrastructure that can’t be replaced easily.
McKenna Consultants delivers hands-on service across consulting, development, and DevOps. However, its small team size and UK-only location can limit scalability or real-time global support.

Cloudflight is a European consultancy focused on building composable commerce solutions on AWS with a foundation in legacy integration. It tailors each build using modern frameworks like commercetools, VTEX, or SAP Spartacus and usually working with complex B2B environments.
One example includes helping Mirka implement a scalable architecture using SAP Commerce Cloud, a headless frontend, and deep ERP integration, all deployed on AWS. Cloudflight is known for strong solution design and iterative delivery, but operates at a higher price point.
It also shifts team members mid-project, which can impact consistency. While its commerce and cloud expertise are okay, you’ll want clear agreements on staffing and integration plans from the outset.

Choosing the right consulting partner shapes the pace, flexibility, and long-term success of your composable commerce platform. You need technical alignment but also a partner who knows how to work within your team’s structure, timeline, and strategic goals.
These are the key factors to evaluate before making a decision:
Pro tip: Planning a phased migration from your monolith? This guide outlines AWS-native benefits retailers are already using to cut costs and scale faster.
Building a modular stack on AWS is a strategy to move faster, reduce risk, and compete at scale. That’s why selecting a consultant with proven MACH experience, cloud-native skill sets, and hands-on delivery models matters.
Nova brings all of that together with certified AWS engineers, nearshore collaboration, and a clear path from planning to performance. Whether you’re migrating from a legacy system or launching new services, Nova helps you get results with fewer delays and better visibility.
To move forward with confidence, schedule a call with Nova for composable commerce consulting that fits how you build.
MACH‑based commerce breaks systems into discrete, independent services (microservices, APIs, headless frontends), while monoliths bundle all commerce logic together. That separation boosts agility and reduces deployment risk across functions like content management, checkout, and inventory services.
AWS infrastructure alone gives you scalable compute, data pipeline tools, and serverless architecture. But to succeed at composable commerce, you still need connectors, APIs, front‑end frameworks, and commerce logic, so you’ll need partners or tooling on top of AWS.
Typical stacks include AWS Lambda for serverless functions, API Gateway for routing, DynamoDB or RDS for storage, CloudFront for global delivery, Cognito for authentication and authorization, and CloudWatch for observability.
Migration timelines vary by scope. It can take as little as a few weeks for an MVP slice. Full replatforming usually takes 6-12 months, depending on team bandwidth, legacy complexity, and phased microservice deployment.
Microservices can increase operational overhead and incur data‑flow, API Gateway, and Lambda costs. That said, you can optimize costs by right‑sizing resources, leveraging serverless scaling, and removing unused services post-launch.
