Cloud Solutions for Bristol Businesses

A Bristol aerospace business in United Kingdom depended on three ageing office servers that were failing more and more often. Over six weeks we moved their workloads to AWS with zero data loss — infrastructure costs came down, maintenance dropped to almost nothing, and they gained automatic failover they had never had.

Architecture Before Infrastructure

Most cloud problems are not really cloud problems — they are architecture decisions made in a hurry that nobody revisited. A lift-and-shift of a few VMs onto AWS often costs more than the office servers it replaced, because the workload was never redesigned for what the cloud actually does well. We start with the workload, not the provider: what has to scale, what has to stay available, where the data lives, and what failure modes you can tolerate.

From there we design a target architecture and put the tradeoffs on the table — managed services versus self-hosted, single region versus multi-region, the cost and complexity each choice carries. You get a documented plan and a migration path before anyone touches a console, so the build is a known quantity rather than a series of surprises.

AWS, Azure and GCP

We work primarily across AWS and Azure, with GCP where it fits. AWS tends to win on breadth and on compute-heavy or data-heavy workloads; Azure is the natural choice when you are already invested in Microsoft identity, licensing and tooling; GCP earns its place for data and analytics-led platforms. The right answer depends on your existing stack and team, which is why we recommend rather than default.

Whichever provider, the building blocks are consistent: properly segmented networking with VPCs or VNets and private subnets, identity and access kept least-privilege, managed databases over hand-rolled ones where they fit, and serverless or container compute chosen to match the traffic shape rather than habit.

Infrastructure as Code, Security and Cost Control

Everything we provision is defined in Terraform, so the environment is reproducible, version-controlled and reviewable rather than a hand-clicked configuration nobody can recreate after the person who built it leaves. Staging and production are described by the same code with different variables, which is what keeps the two environments honestly in sync.

Security is built in from the start, not bolted on after an audit. Encryption at rest and in transit, scoped IAM roles, centralised logging and audit trails, secrets kept out of code, and sensible network boundaries are the baseline. Cost control runs alongside it: right-sized instances, autoscaling, reserved or savings-plan capacity for steady workloads, and lifecycle policies on storage so spend tracks usage instead of drifting upward unnoticed.

• Terraform-defined infrastructure that is reproducible and reviewable
• VPC or VNet segmentation with private subnets and least-privilege IAM
• Encryption at rest and in transit, with centralised audit logging
• Autoscaling and right-sized compute matched to real traffic
• Reserved capacity and savings plans for predictable workloads
• Cost dashboards and budget alerts so spend never drifts silently

Migration, Timeline and Fit

Migrations run in stages, not big-bang. We validate each workload in the new environment before cutting traffic over, keep a rollback path open, and schedule the riskier cutovers for low-traffic windows. A straightforward migration of a handful of services is usually a matter of weeks; a larger estate with databases and stateful systems is phased over a couple of months with the highest-value, lowest-risk pieces moved first.

This is the right work for teams outgrowing on-premise hardware, paying too much on a poorly configured cloud account, or needing reliability and scale they cannot get from a single server. It is not the right time if you are a very early-stage product still finding fit — a managed platform like a PaaS or a single well-run instance will serve you better until the workload justifies real architecture, and we will tell you when that line has not been crossed yet.
