A world of new possibilities

Build Faster with Serverless Architecture

The future of cloud-native development lies in the ability to build and scale applications without the weight of infrastructure management. AWS Lambda, a cornerstone of serverless computing, empowers teams to focus solely on code, driving performance, resilience, and speed to market. By leveraging AWS Lambda and the broader serverless framework, D55 helps businesses architect highly scalable systems that react to real-time events, reduce operational overheads, and maintain cost-efficiency.

At D55, we specialise in designing, building, and supporting robust AWS Lambda solutions. Whether you’re launching a new service or modernising legacy platforms, our team ensures your serverless architecture delivers value from day one.

What Is AWS Lambda?

AWS Lambda is Amazon Web Services’ Function-as-a-Service (FaaS) platform, enabling developers to run code in response to events without provisioning or managing servers. It is a core component of the AWS serverless model, where compute resources are abstracted, auto-scaled, and billed only for actual usage.

Used widely in automation, data transformation, API integrations, and microservices architectures, AWS Lambda supports a variety of triggers including HTTP requests, S3 events, DynamoDB streams, and more. It is tightly integrated with services like CloudFormation, making it easier to deploy consistent environments.

The advantages of AWS Lambda include automatic scaling, granular billing (per millisecond), and seamless connectivity with the AWS ecosystem. It supports use cases where agility, responsiveness, and low-latency compute are critical.

Our Approach at D55
As a UK-based technology consultancy, D55 takes a holistic approach to building and managing AWS Lambda functions. We work with clients to architect solutions that are scalable, observable, and secure.
Our AWS Lambda services include function development, custom event trigger configuration (e.g. via API Gateway, S3, EventBridge, or DynamoDB), and integrating secure, automated CI/CD pipelines. Whether you need an aws cloudformation lambda trigger for system-wide automation, or a next js serverless aws lambda deployment for a frontend platform, our team ensures your solution follows best practices for security and maintainability.
We also help clients navigate multi-cloud and hybrid cloud strategies, ensuring Lambda functions remain interoperable and compliant across environments. All deployments are supported by Infrastructure as Code (IaC) using CloudFormation and the Serverless Framework, with examples such as:
- aws cloudformation lambda example deployments
- aws lambda cloudformation example configurations
- aws lambda permission cloudformation and access policies
Our vendor-neutral mindset means we work with your preferred stack, delivering solutions that are portable and built for scale.
Solution We Deliver
D55 has a strong track record of building real-world systems powered by AWS Lambda and serverless technologies. Our solutions span multiple sectors and use cases:
- Real-time data processing and event-driven automation using serverless Lambda architecture
- High-performance backend APIs built with AWS Lambda and API Gateway
- Seamless integration between Lambda and legacy or containerised environments
- Workflow orchestration via AWS Step Functions, allowing for structured state management
- IoT device messaging, asynchronous task handling, and event scheduling
Our team builds with production in mind, ensuring each Lambda function is tested, monitored, and designed to scale as your user base grows.

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.
