From 12 physical servers to 3: a Ghanaian retail bank cuts its IT bill by two-thirds

The problem

Twelve aging physical servers running in a branch-headquarter closet — monthly electricity and cooling cost of GH₵ 18,000, no disaster recovery, 6-hour restore time, and two hardware failures in 18 months.

What we did

We consolidated the workloads onto three modern hosts running VMware vSphere, configured HA clusters, introduced snapshot-based backups to a remote site in Kumasi, and wrote a live-migration runbook the bank's own admins could execute.

"Flash Code's team embedded with ours for six weeks. They didn't just virtualize the servers — they taught our admins how to own the platform after they left."

How we delivered it

  1. Step 1Discovery

    Full workload inventory and dependency map over two weeks on-site.

  2. Step 2Design

    Right-sized three hosts with N+1 capacity and dual 10GbE for live migration.

  3. Step 3Pilot

    Migrated the non-critical workloads first to prove the runbook before banking hours.

  4. Step 4Cutover

    Weekend migration window with rollback to original hardware if anything failed.

  5. Step 5Handover

    Two-week shadow period and a runbook every admin could read without training.
