Cloud Migration

We rebuilt and migrated a BSI C5-compliant hospital platform in months after another provider spent over a year on it. For Telekom, we cut infrastructure cost by 50 % at 99.98 % availability. Your migration starts with an inventory and ends with a platform your team runs or we do.

What exactly is Cloud Migration?

Not moving servers from A to B. Anyone can do that and end up with the same problems on a more expensive bill. A real migration is a set of decisions: what moves as it is, what gets modernised, what stays on-prem for good reason. And it means sorting out security, compliance and monitoring before production traffic moves, not after the first incident.

At iits, cloud architecture, software engineering and CloudOps sit in one team. So you don't just arrive in the cloud. You arrive able to run it

Sovereign cloud or hyperscaler? Both, if it makes sense.

We're a long-standing T Cloud Public partner and build on STACKIT, AWS, Azure and GCP. So the platform question gets answered by your data, your regulator and your budget, not by whoever we happen to resell.

Modernise where it pays, move where it doesn't

Not every workload deserves a rewrite. We decide per application whether it's rehosted, replatformed or refactored, based on business value, dependencies and what it costs to run afterwards. You get a portfolio decision you can defend to finance.

Day-two operations, built in from day one

A migration is done when your team can run the platform. Landing zone as code, GitOps deployments, monitoring and backup live before traffic moves. Runbooks and dashboards included or our CloudOps team keeps operating it for you.

Benefits of an iits Cloud & DevOps Team

We migrate the systems others won't touch. KRITIS, healthcare, petabyte-scale data on sovereign cloud or hyperscaler, whichever the regulator and the workload demand.

  • Built for regulated and critical workloadsKRITIS, hospitals, utilities, carriers. BSI C5 controls and GDPR requirements built into the platform design, with auditability built in.
  • Platform choice follows workload and regulationT Cloud Public or STACKIT when the regulator says so, AWS, GCP or Azure when the workload does. Leading T Cloud partner, direct line to T-Systems.
  • Petabytes, not pilotsProduction data at petabyte scale, with transfer plans and cut-over windows that hold.
  • 55 Terraform modules, 40 Helm chartsEvery landing zone from a tested library, deployed via GitOps. Built from tested, reusable modules rather than one-off infrastructure.
  • We stay after go-live, if you wantKumoOps: fixed monthly price, incident response under 15 minutes, live chat instead of tickets.

Four steps. No surprises at the end.

  1. Step 01

    Know what you're moving

    Inventory, dependencies, compliance needs, TCO per workload. The business case before the first ticket.

  2. Step 02

    Build the foundation once

    Landing zone from our Terraform and Helm library: network, identity, encryption, guardrails. BSI C5 and GDPR designed in.

  3. Step 03

    Move in waves, rehearse every one

    Low-risk first. Each wave has a dry run, a rollback path and a downtime window you knew about in advance.

  4. Step 04

    Go live, hit the numbers, hand over

    We stay until availability and cost meet the targets from step one. Then your team runs it, with runbooks or we do.
