managed services

Managed services on AWS that look like an extension of your engineering team.

Basic
Standard
Premium

Senior people on your work, direct access, cost discipline and security posture as part of the daily engagement. Three support tiers fitted to your operational tempo. AWS-funded assess phase where eligible.

The handover

After the migration

Your application or platform is live on AWS. The business depends on it. The build engagement is finished. What sits underneath is the day-to-day operational work of running an AWS estate well: cost discipline, security posture, incident response, capacity planning. Each of those is real work, and together they absorb the senior engineers most able to drive your next phase.

Our Managed Services practice exists to take that operational tail off your in-house team, with senior people who know your estate and direct access for the questions that matter.

The cost of leaving it

Where the cost shows up

In cost drift

Your AWS bill grows faster than the work it supports because nobody owns the daily discipline of right-sizing, reserved instance allocation, and waste elimination.

In risk

Security misconfigurations, missed patches, drift between environments, and the gradual decay of the original architectural intent, the kind of issues that don’t surface until they cause an incident.

In capacity

Your senior engineers who could be designing the next phase are absorbed by the operational tail of the last one, and your strategic roadmap moves more slowly than the build engagement promised.

The model

A continuing partnership, not a help desk

Managed services should look like an extension of your in-house engineering team rather than a tier-one ticket queue. Senior people who know your estate, accessible directly, with cost discipline and security posture as part of the daily work rather than a quarterly review item.

Your monthly or quarterly review is anchored on the metrics that matter: cost trajectory, availability, team productivity, and security posture. Not just SLA compliance.

Our approach

How we approach it

1

Assess first, AWS-funded where eligible

Most engagements begin with an assess phase. Where your workload is migration-adjacent, the AWS Migration Acceleration Program may apply and we handle the funding application. The assess covers your current cost shape, security posture, operational risks, and any quick-win optimisation work. The output is a clear shape for the ongoing engagement.

2

Run as an extension of the engineering team

Our senior engineers join your in-house engineering rhythm rather than imposing a separate service desk model. Direct access; critical incidents escalate to senior architects immediately; cost and security recommendations come with the business-impact reasoning, not just the technical change.

3

Quarterly business review, not just SLA reporting

The review every quarter (monthly on the Premium tier) is anchored on your business metrics: cost trajectory, availability, team productivity, security posture, the operational risks coming up. Skills transfer continues into the engagement. Where your in-house team wants to take over an area of operational work, we hand it back.

The outcome

What changes for your business

Expertise

A senior team running your AWS estate that your in-house engineers can rely on, without the cost or hiring effort of building the equivalent in-house.

Governance

Cost discipline made visible. Detailed monthly analysis by service, region, and team, with the next action explained in business terms, so your finance team sees where the spend is and what the next move does.

Assurance

Security posture maintained as continuous work. Drift between environments is caught early, patches applied to schedule, and audit evidence produced on demand, so your next audit cycle becomes a confirmation exercise rather than a scramble.

Response

A senior incident response team available for the issues that matter, with the right escalation path into senior architects when an issue is genuinely critical.

Focus

Your in-house engineering team back to building features rather than triaging operational work.

Proof

Where we’ve done this

Our Managed Services engagements continue the work from build engagements in Energy, Transport and Logistics, Maritime, and adjacent mid-market UK workloads. The sector context that matters in those builds (regulatory requirements, operational tempo, integration with sector systems) translates directly into the managed engagement.

FAQ

Questions we get asked

How small can the engagement be?

The Basic tier fits steady-state workloads where your in-house team handles routine operational work and brings us in for specialist questions. There’s no minimum size beyond the assess phase scoping; the engagement adapts to your workload.

Are you 24 by 7?

The Premium tier is 24/7 proactive monitoring and incident response with named senior engineers and a monthly business review. The Standard tier is extended-hours; the Basic tier is business-hours. The right tier for you comes out of the assess phase.

How is this different from a generic IT managed service provider?

Two ways. AWS-native depth: we’re an AWS Advanced Consulting Partner with the Migration and Modernisation Competency and the Energy Competency, and our senior engineers spend their working week on AWS estates rather than on mixed IT estates. Sector context: direct working experience in Energy, Transport and Logistics, and Maritime, where the regulatory and operational requirements are different from a generic business workload.

Will you push us toward more services?

Recommendations are independent of our interest in selling you further engagement. Cost optimisation work that reduces our revenue gets the same priority as cost optimisation work that doesn’t. Skills transfer to your in-house team is part of the engagement, with the explicit aim of not creating a permanent dependency.

Can we trial this?

The assess phase is your trial. AWS-funded where eligible. It produces a clear shape for the engagement and lets your team see how we make operational recommendations before committing to the ongoing tier.
