Cloud migration
Migrate from On-Premises to Cloudfor cost optimization and business agility
Leaving your own servers changes latency, file handling, backups and how you pay. Find out what your systems actually depend on before choosing a provider or a date.
Your server room has been doing more than you think
On-premises systems grow around their surroundings. Everything sits on one fast local network, a file share is always there, someone restarts a service when it hangs, and a nightly job exports to a folder another system reads. None of it appears on an architecture diagram, and all of it matters on the day you move.
So the first job is to find out what exists. That means listing servers, what runs on them, what each one connects to, which scheduled tasks run, and who is responsible. Connection logs and traffic captures are more reliable than memory. Each cloud vendor has discovery tooling for this, but a conversation with whoever has run the place for ten years usually turns up something the tooling can't.
Things that behave differently after the move
- Latency. An application that makes hundreds of small database queries per page works on a local network and crawls if the database stays behind. Components that talk constantly should move together.
- File shares. Applications that read and write shared folders need managed file storage, object storage or code changes. Object storage isn't a drop-in replacement for a file system.
- IP addresses. Hard-coded addresses in config, firewall rules and partner allow-lists all need updating, and a partner's change process can take longer than your migration.
- Backups. Your tape or NAS routine doesn't transfer. Decide what to back up, where, for how long, and test a restore in the new environment.
- Costs. On-premises hardware is already paid for, and the cloud bills for running time, storage and outbound data. Servers sized for peak load and left running can cost more than expected.
- Licensing. Some commercial software is licensed per socket or tied to specific hardware. Check the terms before you assume it can move.
Pick a route for each system
Not everything should go the same way. A healthy application on a supported operating system can often be rehosted, with little change. A database might move to a managed service to take patching off your list. An application on an unsupported stack needs upgrading first, because moving it just relocates the risk. Some systems shouldn't move at all, such as hardware-attached equipment on a factory floor or anything scheduled to be retired within the year.
We sequence from low risk to high: something small and internal first, so the team learns the network, the monitoring and the process on a system where a mistake costs little.
The cutover itself
Replicate data ahead of time so that the final sync is small. Lower DNS TTLs in advance. Write the rollback steps down, including who decides and by what time. Run the switch with the people who know the application watching it, and keep the old servers intact until a full business cycle has passed, including month-end if the system does any accounting.
What we can show you
We have no published case study of a data-centre exit. We do manage servers and run monitored backups for maintenance clients, and we have moved old applications onto current stacks. If your systems are mostly your own applications and databases, that overlaps with what you need. If you have racks of mixed commercial software, you will want a dedicated infrastructure partner alongside us.
On-premises migration questions
Which cloud should we choose?
Existing licences, staff skills and the managed services you want usually decide it. If you already run Microsoft SQL Server and Active Directory, Azure is worth pricing first. Compare with your real workloads, not list prices.
Do we have to move everything at once?
No. Moving in waves is safer, though systems that talk constantly should move together. You will run a hybrid setup for a time, so plan a secure network link between the two.
