Cloud Migration Services

Move your infrastructure to the cloud with confidence — zero downtime, US data residency, and a clear migration plan.

Cloud migration is not just about moving servers — it is about rethinking how your application runs, scales, and recovers from failure. A lift-and-shift that simply moves VMs to EC2 misses the entire point. A proper cloud migration modernizes your infrastructure, reduces operational burden, and unlocks capabilities that were impossible on-premise.

We have guided businesses through cloud migrations ranging from simple single-application moves to complex multi-service migrations with strict compliance requirements. We specialize in AWS and GCP, with experience across Azure for organizations already invested in the Microsoft ecosystem.

For US businesses with data residency requirements — particularly in healthcare, finance, and government — we ensure your data stays in US regions (AWS us-west-2 in Oregon, GCP us-west1 in Oregon) while leveraging the full power of cloud-native services.

What You Get

📋

Migration Assessment

Comprehensive audit of your current infrastructure, dependencies, and data flows to build a realistic migration plan with timelines and cost projections.

🔄

Zero-Downtime Migration

Phased migration strategies with parallel running, DNS cutover, and rollback plans so your users never experience an outage during the transition.

🇺🇸

US Data Residency

Architecture designed to keep data in US cloud regions for HIPAA, state privacy laws, and government compliance requirements.

💰

Cost Optimization

Right-sized instances, reserved capacity planning, spot instance strategies, and ongoing cost monitoring to avoid cloud bill shock.

🔒

Security Architecture

VPC design, IAM policies, encryption at rest and in transit, secrets management, and security group configuration following cloud security best practices.

📈

Auto-Scaling Configuration

Horizontal and vertical auto-scaling policies, load balancer configuration, and capacity planning so your infrastructure matches demand automatically.

Our Migration Methodology

Every migration starts with a thorough assessment. We map your existing infrastructure — servers, databases, storage, networking, scheduled jobs, and all the undocumented dependencies that only surface when you try to move things. This assessment produces a dependency graph and a migration sequence that minimizes risk.

We then execute the migration in phases, starting with the lowest-risk components. Each phase follows a pattern: provision cloud infrastructure, replicate data, test thoroughly, switch traffic with DNS or load balancer changes, monitor for issues, and decommission old infrastructure only after a validation period.

Rollback is always an option. We maintain the old infrastructure in parallel until the migration is validated, and every cutover step has a documented rollback procedure. If something goes wrong, we revert within minutes, not hours.

Choosing the Right Cloud Architecture

Not every application needs Kubernetes. We match the architecture to your actual requirements and team capabilities. For many applications, managed services like AWS ECS with Fargate or GCP Cloud Run provide container orchestration without the operational overhead of managing a Kubernetes cluster.

For databases, we evaluate managed services like RDS, Cloud SQL, or Aurora against self-managed options. Managed databases cost more per hour but eliminate backup management, patching, replication setup, and failover configuration — work that would otherwise consume significant engineering time.

We also consider serverless architectures for appropriate workloads. Lambda functions for event processing, API Gateway for simple APIs, and Step Functions for workflow orchestration can dramatically reduce costs for variable-traffic applications.

Database Migration and Post-Migration Optimization

Database migration is typically the highest-risk part of any cloud migration. For PostgreSQL and MySQL migrations to managed services, we use native replication to keep the cloud database in sync with the source. When the data is caught up, we switch the application to the cloud database in a brief maintenance window — often under five minutes of downtime. For large databases where even minutes of downtime are unacceptable, we use change data capture (CDC) with tools like AWS DMS or Debezium to stream changes in real-time.

Migration is not the finish line — it is the starting point for cloud-native optimization. Once your workloads are running in the cloud, we optimize: right-sizing instances based on actual CPU and memory usage, implementing auto-scaling policies, setting up CloudWatch or Cloud Monitoring dashboards, and configuring cost alerts. We also implement infrastructure as code using Terraform or Pulumi, ensuring your cloud environment is reproducible, version-controlled, and auditable.

Frequently Asked Questions

How long does a cloud migration take?
A single application migration typically takes 4-8 weeks. Complex migrations involving multiple services, databases, and compliance requirements can take 3-6 months. We work in phases so you see progress continuously and each phase adds value independently.
Can you keep our data in the US?
Yes. AWS has multiple US regions including us-west-2 in Oregon and us-east-1 in Virginia, and GCP has US regions in Oregon, Iowa, and South Carolina. We architect your infrastructure to keep all data within US regions, which satisfies HIPAA, CCPA, and most state and federal data residency requirements.
How much will cloud hosting cost compared to our current setup?
It depends on your current spend, but most teams see comparable or slightly higher raw hosting costs offset by significantly lower operational burden. We provide detailed cost projections during the assessment phase and optimize aggressively after migration. Reserved instances and savings plans typically reduce costs by 30-50% versus on-demand pricing.
What if something goes wrong during migration?
Every migration phase has a documented rollback procedure. We maintain old infrastructure in parallel during the transition and can revert any change within minutes. We have never had a migration cause extended downtime — because we plan for things going wrong.
