E-Commerce Cloud Services

From new store launches to global scaling, D55 delivers tailored e-commerce cloud services that perform today and adapt for tomorrow

Built for Your Commercial Goals

Your e-commerce business is unique. We architect cloud and data solutions that support your commercial model, operational needs, and growth ambitions.

Proven Across B2C, B2B & DTC

Our AWS expertise helps e-commerce businesses of all types achieve the speed, reliability, and data-driven insights needed for conversion and retention.

Future-Proof Your Platform

From handling traffic spikes to expanding into new markets, your cloud infrastructure will evolve with you, eliminating the need for costly and disruptive rebuilds.

Platform-Agnostic Cloud Solutions

Whether you’re on Magento, Shopify Plus, BigCommerce, or a custom-built platform, we architect a supporting AWS environment. Our cloud migration and consultancy services are designed to enhance your existing technology, not replace it.

Modern Architecture for Speed & Agility

Slow sites kill conversions. Our application modernisation services help break down monolithic backends into agile microservices, enabling faster feature rollouts, smoother checkouts, and the flexibility to go headless.

Connected Data & Systems

Gain a single view of your customer and operations. Our data engineering and integration services create seamless connections between your store, ERP, CRM, and marketing platforms, unlocking powerful analytics and AI-driven personalisation.

Secure & Reliable Managed Services

Focus on growing your business, not managing servers. Our AWS managed cloud services provide enterprise-level security, proactive monitoring, and 24/7 support to ensure your store never skips a beat.

Transparent Process

Continuous Optimisation & Management

Post-launch, we provide continuous cloud cost optimisation, performance tuning, and proactive infrastructure management, so you can focus on your business while we ensure your systems work 24/7.

More Than Consultants

We act as an extension of your team, combining high-level cloud strategy with expert technical delivery.

" D55 enabled us to migrate from on-premise to a cloud-based solution, resulting in monthly cost savings of about 40%. Cloud-based systems give us a high level of resiliency and an unlimited capacity to scale. We’ve really put in place the foundations for later phases of work and further cost reduction as we scale. It was a partnership as opposed to a service - we work well together. "

Frequently Asked Question

1. Do you only work with Shopify or BigCommerce?

No. We work with major platforms but also deliver bespoke builds, adapting to your stack and goals.

2.What is headless commerce and do I need it?

Headless separates the front-end from the back-end, giving you more control, faster performance, and design flexibility. It’s ideal for scaling brands.

3. Can you integrate with our existing ERP or CRM?

Yes. We specialise in complex integrations — ensuring your systems (sales, fulfilment, finance, marketing) work seamlessly together.

4. How do you ensure security and compliance?

We follow strict coding standards, implement encryption, and design architectures that comply with GDPR, PCI, and ISO requirements.

5. Do you provide ongoing support?

Absolutely. Beyond launch, we provide monitoring, audits, performance optimisation, and feature iterations.

6. How do you ensure security and compliance?

We follow a multi-layered approach. Our code adheres to OWASP Top 10 standards. On the infrastructure side, we use AWS Config for compliance monitoring, IAM for strict access control, and ensure all data is encrypted at rest and in transit. We design architectures that comply with GDPR, PCI DSS, and ISO requirements.
