We move production systems to AWS, Azure or Google Cloud one service at a time, with old and new running side by side until the numbers match. **A published payments migration moved $14M a month with zero downtime and cut infrastructure cost 35%.** Get a fixed quote: https://gigabit.agency/discovery-call/?offer=cloud-migration See what past projects cost: https://gigabit.agency/proof/project-costs/ The short answer ## What good cloud migration services look like. A migration should be boring for your customers. Gigabit migrates with the strangler fig pattern: build the target platform in code first, move one service at a time, run old and new in parallel with shadow traffic, and move the riskiest component last behind a tested rollback. In the published engagement a Series B payments platform left Heroku for AWS while processing $14M a month. The work cost $74,000 over 14 weeks, after a $6,000 assessment. There was no downtime. Deploys went from 38 minutes to 2.5, releases from twice a week to 18 times, payment p99 latency from 340ms to 145ms, and infrastructure cost from $14,200 to $9,230 a month. What we build ## What a migration includes. The DevOps foundation goes in before the first service moves, so every cutover can be watched and reversed. ### Assessment and plan A review of code, schema and traffic that ranks what moves first by risk, with a cost model for the target cloud. ### Infrastructure as code Every resource in Terraform, with environments you can rebuild from scratch and review in a pull request. ### CI/CD and deploys Pipelines with tests, security scanning and blue-green or rolling deploys, so releasing becomes routine. ### Observability Metrics, logs, traces and alerts in place before the first cutover, so a discrepancy shows up in seconds. ### Database moves Replication, read replicas and verified cutovers for large tables, with reconciliation reports you can sign off. ### Cost control Right-sized instances, reserved capacity and tagging, so the bill after the move is lower than before it. How it runs ## Four phases, no big bang. 01 #### Assess Two weeks to map the system, rank the risks and price the migration. 02 #### Build the foundation Infrastructure as code, CI/CD and observability, before any traffic moves. 03 #### Move service by service Low-risk services first, each run in parallel until old and new agree, the core last. 04 #### Hand over Runbooks, knowledge transfer and a failure-injection game day with your team.

Work with no natural end, such as ongoing development, is priced per engineer per month with no lock-in. An honest read ## When to hire us for this, and when not to. A good fit when - Hosting cost or limits are eating margin or reliability. - Deploys are slow or risky, and nobody ships on Fridays. - A customer, auditor or investor wants infrastructure you can document. - The move has to happen without downtime. Look elsewhere when - The app is small and stable where it runs. Moving it adds cost with no return. - You want a lift-and-shift with no tests. We decline those, because the first incident lands on you. - The system is being replaced within a year. Migrate the replacement instead. Proof ## Heroku to AWS at $14M a month, with zero downtime. The full engagement: assessment, foundation, service-by-service migration and the payment core last. Series B payments platform, US-based, $14M monthly transaction volume ### A 14-week strangler-fig migration off Heroku with zero downtime: -35% infra cost, -93% deploy time, +800% deploy frequency. Zero Downtime during migration 38 min → 2.5 min (-93%) Deployment time 2×/week → 18×/week (+800%) Deployment frequency **Investment:** $74,000 · **Timeline:** 14 weeks (2-week assessment + 12-week migration) Read the case study (https://gigabit.agency/proof/cloud-migration-fintech-zero-downtime/) These are past engagements at the prices those clients paid.

FAQ ## Cloud migration, answered #### How much do cloud migration services cost? Our published migration cost $74,000 over 14 weeks, after a $6,000 assessment: an 85,000-line Rails application with a 47-table database moved from Heroku to AWS. Smaller systems cost less. The assessment ends with a fixed price for the migration itself. #### Can you migrate without downtime? Yes. Services move one at a time and run in parallel with the old ones. In the published migration the payment core ran 48 hours of shadow traffic across 12,000 transactions at a 0.00% discrepancy rate, then traffic shifted from 1% to 100% over 10 days with a tested rollback at every step. #### Which clouds do you migrate to? AWS, Microsoft Azure and Google Cloud, from Heroku, other platform hosts, virtual servers or on-premise systems. The assessment recommends a target based on your stack, your team and the cost model. #### Do you offer DevOps consulting after the migration? Yes. DevOps engineers can join your team as an embedded pod at $3,000–$7,500 per engineer per month, or we hand over with runbooks and a game day so your own team runs it. #### Will the migration lower our cloud bill? It should, and you see the cost model before you commit. The published migration cut infrastructure cost 35%, from $14,200 to $9,230 a month.
