Slow releases, manual deployments, and mounting technical debt are costing your business more than you think. D55 designs and builds cloud-native applications on AWS that cut delivery time by up to 50%, reduce deployment incidents by up to 80%, and give your team the automation and DevOps practices to sustain that pace independently. As an AWS Advanced Consulting Partner, every engagement includes full source code ownership, structured knowledge transfer, and a scalable AWS foundation built to Well-Architected standards.
Overview
D55 Cloud-Native Application Development on AWS
D55 is an AWS Advanced Consulting Partner specialising in the design, build, and modernisation of cloud-native applications for scaling businesses. Our service covers the full delivery lifecycle — from architecture design and application build through to CI/CD automation, DevOps enablement, and structured handover — giving customers faster software delivery, lower operational risk, and full ownership of everything we build.
What We Deliver
Cloud-Native Architecture & Solution Design — A documented, agreed blueprint before a line of code is written. High-level and detailed architecture diagrams, AWS service selections, security and compliance considerations, and integration design — reducing delivery risk and accelerating decision-making.
Cloud-Native Application Build & Deployment — Production-ready applications built and deployed on AWS, aligned to the approved architecture. Includes developed components, deployment across environments, Infrastructure-as-Code scripts, and full environment documentation.
Application Modernisation — Legacy components refactored into microservices, containers, or serverless architectures. Covers API enablement, integration modernisation, database migration, and removal of legacy dependencies — reducing technical debt and improving scalability.
CI/CD Pipelines & DevOps Enablement — Automated build, test, and deployment pipelines integrated with Git-based source control and Infrastructure-as-Code. Includes monitoring, logging, and deployment observability.
AWS Landing Zone Deployment — A secure, compliant AWS foundation for all current and future workloads. Customers receive configuration scripts, operational documentation, and reusable templates — reducing future project setup time by up to 70%.
IP & Source Code Handover — Full handover of all customer-owned application source code, with clear documentation of structure, dependencies, and a defined distinction between customer-owned and licensed IP. No lock-in.
Testing & User Acceptance — Structured UAT with defined acceptance criteria, test scenarios, and formal sign-off checkpoints across unit, integration, and system testing.
Knowledge Transfer & Operational Handover — Workshops, runbooks, and a formal handover session so customer teams can operate, support, and extend the solution independently.
Post-Deployment Support (Optional) — Ongoing support with defined SLAs, incident procedures, monitoring, and a maintenance cadence.
Measurable Outcomes
30–50% reduction in application delivery time, 40–60% reduction in manual deployment effort, Up to 2x increase in release frequency, 20–40% reduction in infrastructure costs, 50–80% reduction in deployment-related incidents, Up to 70% reduction in future project setup time
Unlike large system integrators, D55 operates as a boutique specialist — with 50+ AWS certifications, a senior engineering team, and a delivery model built around transparency, enablement, and long-term customer control. Every engagement is delivered by the engineers who designed it. Customers get direct access to expertise, faster decision-making, and a partner invested in their success — not their dependency.
D55 can help qualifying customers access AWS funding programmes — including MAP, POC, and CEI — to offset project costs. We manage all applications and administration on the customer's behalf.
Use cases
Containers, Orchestration and Operations
D55 designs and deploys containerised architectures on AWS using Amazon ECS and EKS — covering container strategy, cluster configuration, service orchestration, CI/CD integration, and operational tooling. Every engagement includes Infrastructure-as-Code, monitoring and observability setup, and full knowledge handover so customer teams can operate and scale containerised workloads independently post-engagement.
Secure Serverless and Containerized Applications
D55 builds secure, production-ready serverless and containerised applications on AWS using Lambda, ECS, and API Gateway — with security and compliance built in from day one. Engagements are aligned to the AWS Well-Architected Framework, with IAM controls, encryption, and network security applied across every environment. Customers receive full source code ownership and knowledge transfer — ensuring long-term control without supplier dependency.
