Cloud & integrations

Cloud Engineering Services on AWS for UK Teams

Design, build or move your applications onto AWS with an architecture that is secure, resilient and sized to your budget — and properly connected to the systems you already run.

  • AWS London region when data must stay in the UK
  • Infrastructure as code, in accounts you own
  • Running costs estimated before anything is built

Why cloud projects disappoint

Moving to the cloud fixes nothing on its own.

Plenty of businesses have moved to the cloud and ended up with the same fragile system and a bigger bill. The difference is in the architecture and how it is run, not the name on the invoice.

What well-engineered cloud gives you

An environment you can explain, afford and change safely:

  • Architecture sized to your real traffic and budget
  • Every environment defined as code and repeatable
  • UK data residency where contracts or customers require it
  • Costs tagged, budgeted and reviewed
  • Integrations that keep cloud and existing systems in step

Lift-and-shift with no redesign

Servers copied across exactly as they were, so you pay cloud prices for the same single points of failure and hand-run deployments.

Bills nobody can explain

No tagging, budgets or alerts: spend grows with every experiment and nobody can say which product, environment or customer it belongs to.

Security left at the defaults

Root credentials in daily use, storage made public by accident and broad permissions granted for convenience — the misconfigurations behind many avoidable leaks.

Systems that do not talk

The new cloud app cannot see stock, orders or customers held in older systems, so staff bridge the gap with exports and re-keying.

How we work

How we deliver cloud projects.

Cloud work carries more hidden risk than most — data, downtime and running costs — so each stage includes a cloud-specific check.

  1. 01

    Discovery

    We inventory what runs now — applications, databases, traffic patterns, integrations, data locations and costs — and note any contractual or regulatory limits on where data can live.

    Current estate and constraints documented

  2. 02

    Strategy

    For each workload we decide whether to rehost, re-platform, rebuild or retire it, comparing running cost, effort and risk, and agree the order of work.

    Migration or build plan with cost estimates

  3. 03

    UX & architecture

    The target architecture: network layout, identity and access, environments, backup and recovery targets, and how cloud services will connect to existing systems.

    Architecture and security design

  4. 04

    Development

    Infrastructure written as code and reviewed like application code, deployed through CI/CD into separate development, staging and production accounts.

    Repeatable, version-controlled environments

  5. 05

    Testing

    Load tests at realistic peaks, failover and restore rehearsals, and security configuration checks before any production traffic arrives.

    Tested failover and restore

  6. 06

    Launch

    Cut-over in a planned window with a rehearsed rollback, data synchronised and DNS switched carefully, and monitoring live from the first minute.

    A planned cut-over with a way back

  7. 07

    Optimisation & support

    Cost and performance reviewed once real usage is known, resources rightsized, then ongoing support or a documented handover to your team.

Technology

The cloud stack we build on.

AWS first, using managed services where they reduce the work of running things, and portable building blocks where lock-in would hurt.

AWS compute

Data and storage

RDS for PostgreSQL and MySQLS3 object storageRedis cachingQueues and event buses

Delivery

Cloud accounts are opened in your name and stay yours. We work in them through named, MFA-protected access, and everything we build is defined in code you own.

Use cases

Cloud projects we are asked to run.

The work that usually brings a business to a cloud engineering partner.

Businesses on ageing servers

Off the office server

A critical application on an office server or co-located machine moved to AWS, with backups, monitoring and a documented recovery plan.

Healthcare and public sector suppliers

UK-hosted by design

Architectures that keep patient or citizen data in the AWS London region, with documentation to support DSPT submissions and buyer security questions.

SaaS start-ups

A production-ready foundation

Separate environments, CI/CD, managed databases and sensible guardrails from the start, so growth does not force a re-platform a year later.

Retail and ticketing

Handling spiky traffic

Serverless and auto-scaling services that absorb a product drop or ticket release, then scale back down so you are not paying for idle capacity.

Firms with legacy systems

Cloud-to-legacy integration

A cloud app connected to an older ERP, finance or line-of-business system through APIs, queues or scheduled file transfers.

Connected devices

Device data at scale

Telemetry from sensors or smart devices taken in through managed IoT and queue services, stored economically and surfaced in dashboards and alerts.

Why Techsleight

What working with us is actually like.

No inflated numbers — just how we run projects, and what you can hold us to.

Product engineering, not ticket-taking

We ask what the software is for before we estimate it — and we will tell you when something should not be built, or should be bought instead.

AI where it earns its place

LLM features, retrieval and automation built with evaluation, guardrails and cost controls, and plain software where that is the better answer.

Full-stack under one roof

Design, frontend, backend, mobile, cloud and QA in one team, so nothing falls between suppliers.

UK-focused delivery

UK business hours, estimates in pounds, and a contract with a UK company. Our engineers are based in the UK and India.

Flexible engagement

A fixed-scope project, dedicated developers or a monthly retainer — and you can move between them as the work changes.

You own everything

Code, IP, cloud accounts and documentation are yours from day one. We sign an NDA before discovery if you need one.

Support after launch

We stay on for fixes, upgrades and new features, or hand over cleanly to your in-house team with the documentation to match.

FAQs

Questions we get asked.

Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.

Ask us a question

Why AWS rather than Azure or Google Cloud?

AWS is our primary platform, so it is where our experience is deepest. If your organisation already runs on Azure or Google Cloud, we work within that estate — switching providers rarely pays for itself on its own.

Can you keep our data in the UK?

Yes. AWS has a London region, and we can design so that data, backups and logs stay there. Some global services process data elsewhere by design; we identify those and either avoid them or document them, so the decision is yours.

How much does a cloud migration cost?

It depends on how many applications and databases move, and whether they move as they are or are re-engineered. A discovery sprint, from £2,000, produces the inventory and plan; the migration is then quoted as a fixed price. We estimate the monthly running cost before you commit.

Will moving to the cloud save us money?

Not automatically. It saves money when you stop paying for idle capacity and hardware refreshes, and costs more when servers are copied across unchanged. We estimate running costs up front and design to them, so you know the answer before the move.

Should we use serverless or containers?

Serverless suits event-driven and spiky work with little to manage; containers suit steady services, long-running processes and teams that want portability. Many systems use both. We choose per workload and explain the trade-off in cost and operational effort.

How do you avoid downtime during a migration?

By migrating in stages, synchronising data before cut-over, rehearsing the switch on staging and picking a low-traffic window. Each stage has a tested rollback. If a short maintenance window is unavoidable, we tell you in advance and plan it with you.

Who owns the cloud accounts and infrastructure?

You do. Accounts are in your name, billing goes directly to you, and the infrastructure is defined in code in your repository. We access it through named, MFA-protected accounts that you can revoke at any time.

Can you connect the cloud platform to systems we already have?

Yes. We connect to ERPs, CRMs, finance systems and partner APIs through supported APIs, message queues or scheduled file transfers, with retries and alerts so a failed sync is noticed rather than silently lost.

Do you support the environment after it is built?

Yes, through our infrastructure support service: monitoring, patching, backup checks and cost reviews in UK business hours, with extended cover by agreement. Or we hand over to your team with runbooks and architecture documentation.

Is the cloud secure enough for regulated data?

The major clouds provide strong building blocks, but security depends on configuration. We design with least-privilege access, encryption, logging and network isolation, and document it for your DPIA, DSPT or customer due diligence. Compliance sign-off stays with you.
