AWS Application Development · UK

AWS application development for UK businesses: designed, built and ready for production.

You have an idea, a manual process or an existing app that needs to grow. KloudCare is a UK AWS consultancy that designs and builds cloud applications on Amazon Web Services: serverless backends, APIs, data, automation and deployment. It runs in your own AWS account and is set up properly for production from the start.

When you need an AWS developer

  • You need a backend or API for a new product, portal or service
  • A manual process (spreadsheets, emails, file handling) should be automated
  • Your app runs on one server and struggles as usage grows
  • Your developers built the app, but deployment, scaling and backups were never set up properly
  • You want to connect systems, such as a CRM, payments or another API
  • You have a front-end team or agency and need someone to own the AWS side

AWS application development services

Serverless application development

Serverless backends and REST APIs on AWS Lambda and Amazon API Gateway, with DynamoDB or RDS for data and Amazon Cognito for user sign-in.

  • REST APIs for web and mobile front ends
  • Customer portals, booking and order backends
  • Pay for what you use, with no servers to patch

Containerised applications on ECS and EKS

Existing or new applications on Amazon ECS or EKS.

  • Apps moved off single servers into containers
  • Load balancing, auto scaling and health checks
  • Separate staging and production environments

Automation, integrations and internal tools

Scheduled jobs, workflows and integrations with AWS Step Functions, S3 and event-driven services.

  • File and data processing that runs on its own
  • Reports and alerts sent by email or Slack
  • Connections between your existing systems

Production-ready setup for existing apps

For apps that work but were never set up properly on AWS.

  • CI/CD pipelines and infrastructure as code with Terraform
  • Monitoring, alerts and automatic backups
  • Security basics: least-privilege access, encryption, secrets management

Need a website front end or a mobile app? We focus on the AWS side and work alongside your designers, developers or agency, who build the screens your users see.

Cloud-native applications built to run without constant attention

Every application is designed to keep running on its own and to tell you when something needs attention.

Resilient by design

  • Managed AWS services instead of servers to look after
  • Automatic restarts, health checks and scaling
  • Production spread across more than one data centre where it matters

Yours to own

  • Runs in your AWS account; you pay AWS directly
  • Code in your own GitHub or GitLab repository
  • Documentation and a runbook for your team

Serverless or containers: choosing the right AWS architecture

There is no single right way to build on AWS. We recommend an architecture based on how your application is used, your budget and your team, and explain the trade-offs in plain English.

Serverless (AWS Lambda)

  • Best for APIs, event-driven workloads and traffic that rises and falls
  • Costs follow usage, often very low for new products
  • No servers or operating systems to patch

Containers (Amazon ECS or EKS)

  • Best for existing applications, long-running processes and steady traffic
  • Run the same container on a laptop, in staging and in production
  • Easier to move an existing app without rewriting it

Design

An architecture, a scope of work, an estimate of AWS running costs and a price for the build.

Build in stages

Working software in a staging environment, with regular demos so you see progress early.

Launch and hand over

Go-live, monitoring and backups in place, documentation, and a walkthrough for your team.

AWS application development pricing

Every application is different, so there is no standard price. The scope of work and the price are agreed with you individually, after a free consultation, before any work starts.

Frequently asked questions

How much does it cost to build an application on AWS?

It depends on what the application needs to do, so every project is scoped and priced individually. After a free consultation we send a written scope of work, a price for the build and an estimate of the monthly AWS running costs, before any work starts.

How long does it take to build an application on AWS?

It depends on the scope. A small API or automation can take a few weeks, a larger application longer. The scope of work includes a timeline with stages, so you see working software early rather than waiting for one big release.

How much will the application cost to run on AWS each month?

Before the build starts, we estimate the monthly AWS running costs for your expected usage. Serverless applications with modest traffic often cost very little to run, and we add budgets and cost alerts so you are told early if costs rise.

Should my application be serverless or use containers?

Serverless (AWS Lambda) usually suits APIs, event-driven work and variable traffic; containers (Amazon ECS or EKS) usually suit existing applications and steady, long-running workloads. We recommend one after understanding your application, and explain why.

Do you build websites and mobile apps?

We focus on the AWS side: backends, APIs, data, automation and deployment. For the screens your users see, we work alongside your own developers, designers or agency.

Who owns the code and the AWS account?

You do. The application runs in your own AWS account, you pay AWS directly, and the code lives in your own GitHub or GitLab repository. You receive documentation so any engineer can work on it later.

Can you work with our existing developers?

Yes. We can take ownership of the AWS architecture, infrastructure and deployment pipelines while your team builds the product features.

What happens after launch?

The application is handed over with monitoring, alerts, backups and a runbook in place, with alerts sent to your team. Ongoing support after launch is available on request, during UK working hours, and is agreed separately.
