A cutover nobody notices
Rehearsed against production-shaped data, executed behind a flag, with a tested rollback at every stage. The goal is a migration your customers never find out about.

Cloud Modernization & Migration Services
Off the legacy stack without the migration horror story.
Everybody knows a migration that went badly. A weekend that became a fortnight, a rollback that did not work, a bill that arrived three times larger than the one it replaced. The stories are common enough that plenty of businesses stay on infrastructure they have outgrown simply because moving sounds worse.
It is a planning problem more than a technical one. Cloud modernization at Zefract means mapping what you actually have before touching it, choosing honestly between lifting and rebuilding, and rehearsing the cutover until it is boring, with cost control from day one rather than after the first invoice.
Cloud Migration
Mapping every dependency and integration before anything moves, because the surprises in a migration are almost never in the part you planned for.
Then the decision per workload: lift and shift where the system is fine and the hosting is not, replatform where a managed service removes maintenance. Rehearsed against production-shaped data, with a tested rollback at every stage.
Includes- AWS / Azure / GCP
- Lift and shift
- Replatforming
- Migration planning
Cloud Native
Rebuilding for the cloud where the return justifies it: containers, serverless and managed services that remove whole categories of work rather than relocating them.
Not everything should be. Cloud-native architecture adds operational complexity that pays off at some scales and is pure overhead at others, and we will tell you which side you are on.
Includes- Microservices
- Containers
- Serverless
- Managed services
Cost Optimization
The cloud bill is a design output, not a fixed cost. Most accounts carry substantial spend on over-provisioned instances and resources nobody has looked at since they were created.
FinOps practice means rightsizing against real usage, reserving capacity where demand is predictable, and monitoring spend so an unexpected increase is noticed in days rather than at quarter end.
Includes- FinOps
- Rightsizing
- Reserved capacity
- Spend monitoring
Resilience & Scaling
Auto-scaling and high availability configured deliberately and then tested, because untested failover is a hope rather than a plan.
Backups and disaster recovery are treated the same way: restored from at least once, so you know the recovery works and how long it takes before you need it.
Includes- Auto scaling
- High availability
- Disaster recovery
- Backups
Why it matters
The cloud does not save money by itself. It saves money when it is run properly.
Moving a badly-behaved system onto rented hardware gets you the same system with a monthly bill attached. The savings come from what you do afterwards: rightsizing what was over-provisioned, using managed services instead of maintaining your own, and switching off the things nobody has looked at in two years.
Here’s what doing it properly returns:
A bill you can explain
FinOps practice from the start: rightsizing, reserved capacity where usage is predictable, and spend monitoring so a surprise is caught in days rather than at quarter end.
It stays up under pressure
Auto-scaling and high availability configured deliberately, so a traffic spike is absorbed rather than survived, and tested, because untested failover is a hope rather than a plan.
Recovery you have actually tried
Backups and a disaster recovery plan that have been restored from at least once. An untested backup is not a backup, and most organisations discover this at the worst possible moment.
Less to maintain
Managed services and serverless where they fit mean whole categories of patching, upgrades and capacity planning stop being your team’s problem.
An honest lift-or-rebuild call
Some workloads should simply move; others should be rebuilt for the cloud, and a few should stay where they are. We make that call per workload and show the reasoning rather than selling one answer.
A good migration is not an achievement anyone outside the team notices. It is the one where the numbers improve, the bill goes down, and nobody has a story to tell afterwards.
Why Cloud Modernization with Zefract
One team, one goal, nothing lost in the handoff.
The people moving your infrastructure are the same people who understand the application running on it, so the migration plan accounts for how the software actually behaves rather than treating it as a black box to be relocated.

Frequently asked questions
Not by itself. Moving a system onto rented hardware gets you the same system with a monthly bill attached. Savings come from what follows: rightsizing what was over-provisioned, replacing components with managed services, and switching off resources nobody has looked at in years. We model the running cost before the move rather than after.
The plan is none, and it is a planning problem rather than a technical one. Cutovers are rehearsed against production-shaped data, run behind a flag, with a tested rollback at every stage. Where a window genuinely cannot be avoided we tell you its length before you commit, rather than discovering it on the night.
Per workload, not per project. Some things should simply move, some are worth rebuilding to remove maintenance permanently, and a few should stay where they are. Rebuilding everything is how migrations overrun; lifting everything is how they fail to deliver a benefit. We show the reasoning for each.
Whichever fits your workloads, your team’s existing skills and your commercial position. AWS, Azure and GCP are more alike than their marketing suggests, and the deciding factors are usually the managed services you will actually use and what you can negotiate. We are not tied to any of them.
Designed and then actually tested, because an untested backup is a belief rather than a safeguard. We agree how much data you can afford to lose and how long recovery may take, build to those targets, and restore from backup at least once so both numbers are known before you need them.
