Cloud Migration Services
We move production workloads to AWS, GCP, and Azure without downtime. Every migration starts with a dependency audit and ends with a tested rollback plan — because surprises belong in birthday parties, not cutovers.
What a Production Cloud Migration Actually Involves
Most migrations fail not because of the tooling — but because of what wasn't mapped before the first resource moved.
Discovery & Dependency Mapping
Every service, database, secret, and third-party dependency catalogued before a single resource moves. We map inbound and outbound network flows, identify undocumented cron jobs and batch processes, and surface the hidden dependencies that blow up cutovers at 2am.
Migration Architecture
Target state design: VPC layout, subnet strategy, IAM role hierarchy, networking, data replication approach, and cutover sequence. We don't start configuring resources until the architecture is reviewed — changing a VPC CIDR mid-migration is not a good time.
Zero-Downtime Cutover
DNS TTL management, blue-green or canary routing, database replication windows timed to your lowest-traffic period. We don't do big-bang migrations. We do parallel-running periods with verified traffic and a clean signal before DNS flips.
Data Migration
PostgreSQL, MySQL, MongoDB, Redis, S3, and proprietary data stores. Schema migrations handled with Flyway or Liquibase. Backups verified before replication starts. Checksums validated after. We don't consider a data migration complete until both sides agree on row counts.
Rollback Planning
Every migration has a tested rollback. Before any cutover starts, we rehearse the abort procedure — what gets reverted, in what order, and who confirms it worked. We've never had to execute a post-cutover rollback, but the plan always exists and is always tested.
Post-Migration Optimization
Right-sizing instances based on actual post-migration metrics, Reserved Instance or Savings Plan coverage, tagging strategy for cost allocation, and dashboards that show you the bill before the bill arrives. The cloud should be cheaper than what you left — we make that happen.
How We Run a Migration
Five phases. No surprises. Every phase has a clear exit criterion before the next begins.
Pre-Migration Audit
We inventory everything: services, databases, secrets, network dependencies, third-party integrations, scheduled jobs. We map the data flows, identify what can be migrated independently and what has hard dependencies. The output is a migration dependency graph and a prioritized risk register.
Target Architecture
We design the target state from first principles — not a lift-and-shift of your current architecture unless that's the right call. VPC layout, IAM, network topology, managed services where they reduce operational burden, and a cost estimate before we build anything.
Parallel Running
Target environment built and tested. Data replication running. Applications deployed and verified in the new environment. Traffic not live yet. We run both environments in parallel until we have confidence in the target — not a fixed number of days, but until every health check passes and every metric looks right.
DNS Cutover
TTL lowered 48 hours before the cutover window. Cutover executed during lowest-traffic period. DNS flipped, replication lag confirmed at zero, application health validated on new infrastructure. Old environment kept warm for the rollback window — typically 24-72 hours — then decommissioned.
Post-Migration Optimization
First 30 days: right-sizing based on actual workload metrics. Reserved Instance or Committed Use Discount purchasing once utilization patterns are confirmed. Tagging strategy enforced. Cost dashboard delivered. We don't declare a migration done until the bill makes sense.
Tools & Technologies
We use the right tool for each migration — not a fixed stack regardless of your requirements.
Common Questions
How long does a cloud migration take?
Depends on scope. A single application with a clean codebase and a managed database: 2–4 weeks. A multi-service platform with legacy databases, on-premise dependencies, and compliance requirements: 6–12 weeks. We scope this honestly after the discovery sprint, not before. Anyone quoting you a fixed timeline without an audit is guessing.
Can you migrate us with zero downtime?
For most web applications and APIs, yes. Database migrations are the hard part — we use replication-first approaches that keep both systems live until the cutover is confirmed clean. The only workloads where zero-downtime is genuinely difficult are tightly-coupled stateful systems with no replication support. We'll tell you which category you're in during the audit.
Which cloud providers do you work with?
AWS, GCP, and Azure — including multi-cloud setups and migrations between providers. We don't have a preferred vendor and we don't receive referral fees. We recommend what fits your team's operational skills, your workload's characteristics, and your cost constraints.
What if the migration goes wrong mid-cutover?
We pre-stage and test rollback procedures before every cutover window. If something fails mid-migration, we revert within the cutover window. The rollback is scripted, not improvised. Old environment stays live until we've confirmed the new one is clean — we never decommission the source before we're certain. We've never had to execute a post-cutover rollback, but the plan always exists.
