Context
The fintech company had started with a managed Linode service that made sense at an earlier stage: it reduced operational burden, gave the team a working platform, and kept infrastructure decisions contained while the product moved forward.
Over time, that convenience became expensive. The monthly bill was sitting around $4k-5k, and the team needed more control over where the platform ran, how it was operated, and what it really cost to keep online.
The brief was not "find cheaper servers". The brief was to change the operating model without creating a reliability, compliance, or ownership problem in the process.
Constraints
Four risks shaped the work.
- Downtime had to be treated as a business risk, not a cleanup task.
- Sovereign cloud and data-residency expectations mattered because the client operated in fintech.
- Moving away from managed hosting meant the operational burden had to be designed, not ignored.
- The new platform had to stay reliable after the migration, not just cheaper on invoice day.
That made the architecture decision inseparable from the migration plan. A lower bill only counted if the client could trust the platform after cutover.
Approach
NearLunar owned both the architecture and the migration execution.
The first step was to understand what the managed Linode service was really providing: which parts were essential, which parts were convenience, and which parts were quietly driving cost. From there, the target environment was designed on a sovereign cloud provider with the minimum shape needed to run the platform safely.
The new setup traded managed-service cost for a clearer self-managed model. That meant documenting the operational assumptions, preparing the target environment before cutover, and making sure the team would not inherit a cheaper but fragile system.
Migration
The move was planned as a controlled migration rather than a dramatic rebuild.
The target environment was prepared first. Workloads were validated before production dependency moved. Operational checks were put in place before the new environment became the source of truth. Cutover only happened after the platform shape, runtime assumptions, and fallback options were understood.
This kept the migration focused on reducing risk at each step: build the new environment, prove it can carry the workload, move deliberately, then validate cost and reliability after the switch.
Outcome
The monthly infrastructure bill dropped from roughly $4k-5k to below $400, a reduction of more than 90%.
The client also gained a more transparent operating model. Instead of paying for a managed service that had outgrown the platform's needs, the fintech company moved to self-managed sovereign cloud infrastructure with clearer ownership and a much lower recurring cost base.
The important result was not only the lower number. It was reaching that number while treating uptime, fintech constraints, reliability, and post-migration operations as first-class concerns.
When This Pattern Fits
This kind of work fits teams whose cloud bill has become a symptom of a deeper ownership problem.
If infrastructure cost keeps rising faster than confidence, the answer is rarely a blind provider switch. The safer move is to understand what the platform really needs, choose an operating model that fits the business, and migrate with enough discipline that the savings do not create the next incident.
