Managed Services

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

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.

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.

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 are all the kinds 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.

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 business review every month or quarter is anchored on your business metrics across cost trajectory, availability, team productivity, and security posture, not just on SLA compliance.

How we approach it

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 output is a clear shape for the ongoing engagement.

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; recommendations come with the business-impact reasoning.

Three tiers, one delivery model

Basic. Business-hours support, proactive cost and security reviews, monthly reporting. Steady-state workloads.

Standard. Extended-hours support, dedicated D55 contact, weekly cost and security reviews, quarterly business review.

Premium. 24/7 proactive monitoring and incident response, named senior engineers, monthly business review, capacity planning into your roadmap.

What changes for your business

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. Cost discipline made visible: detailed monthly cost analysis by service, region, and team. Security posture maintained as continuous work rather than annual audit panic. A senior incident response team available for the issues that matter. Your in-house engineering team back to building features rather than triaging operational work.

Where we've done this

Adrian Hobbins, CTO at Bryt Energy: "Thanks to D55 and AWS we don't have to worry about the day to day, so we can focus on the exceptional opportunities for our industry."

Arran Stevenson, Director of Architecture at ENSEK: "D55 have proved to be an excellent development partner offering expertise and predictable delivery, with flexibility to respond to changing business needs."

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.

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.

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

AWS-native depth (Migration and Modernisation Competency, Energy Competency, senior engineers on AWS estates not mixed IT) plus direct working experience in Energy, Transport and Logistics, and Maritime.

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.
