We've migrated 5+ enterprises across fintech, healthcare, and logistics, with zero critical incidents. That's not luck — it's the result of planning every migration carefully, mapping every dependency, and owning the process end to end, from initial assessment through post-migration optimization.
Six risks we
engineer away.
These aren't edge cases. They're the six most common reasons enterprise cloud migrations go over budget, over schedule, or over the news.
Dependency Hell
Undocumented dependencies between applications cause post-migration failures that take days to diagnose. Most teams discover 40% more dependencies than they knew about.
Cloud Cost Shock
Lift-and-shift without optimization creates cloud bills 3× higher than on-premises. Over-provisioning, unattached volumes, and idle resources compound monthly.
Database Migration Complexity
Database migrations require meticulous CDC setup, cutover coordination, and validation. Poor planning leads to data inconsistency or hours of downtime at cutover.
Security Gaps Post-Migration
Default cloud configurations are insecure. IAM policies too permissive, storage public, secrets in code. Security retrofitted after migration is harder than building it in.
Downtime Risk
Business-critical systems migrating during business hours, or teams without tested rollback plans, create unnecessary risk for production incidents.
Skill Gaps in the Target Environment
Your on-premises team knows your current environment. Cloud operations require different skills, different tooling, and different runbooks. The knowledge transfer gap is real.
We read your architecture before we touch anything.
Most migrations fail because teams underestimate dependencies. We map everything first — then move it.
Migration Assessment & Planning
We audit your existing infrastructure before we move anything. Application dependencies, data flows, compliance requirements — mapped before the first Terraform module is written. You won't discover dependencies at cutover.
Multi-Cloud Architecture Design
AWS, Azure, GCP — or all three. We design for your actual workload requirements, not vendor preference. We'll tell you honestly which cloud fits which workload, and why.
Zero-Downtime Migration Execution
Blue-green deployments, canary releases, CDC replication, and traffic shifting strategies. Every migration without a single critical incident — not luck, but methodology.
Cloud Cost Architecture
Cloud bills that grow forever are a sign of poor architecture. We right-size instances from day one, implement auto-scaling, set up cost anomaly detection, and reserve capacity where it saves money.
Security-First Migration
VPC design, encryption at rest and in transit, IAM least-privilege, and network segmentation — all implemented during migration. Security that's designed in, not bolted on.
Post-Migration Optimization
90-day post-migration performance review, cost optimization pass, and reliability improvements. Most clients see 30–40% cost reduction vs. on-premises within six months.
Four phases.
One team. No handoffs.
Discovery & Assessment
- Inventory all applications and infrastructure dependencies
- Classify workloads by migration strategy (rehost/replatform/refactor)
- Identify compliance and data residency requirements
- Produce architecture recommendations and cost estimates
Landing Zone & Foundation
- Set up AWS/Azure/GCP landing zone (VPC, IAM, networking)
- Configure security baseline, monitoring, and logging
- Deploy CI/CD pipeline for infrastructure as code
- Create DR architecture, runbooks, and rollback procedures
Migration & Validation
- Migrate workloads by priority (low-risk first)
- Run parallel environments for thorough validation
- Load testing and performance benchmarking in target
- Security testing and compliance verification
Cutover & Stabilize
- Planned traffic cutover with instant rollback capability
- Hypercare support for 30 days post-cutover
- Cost optimization and right-sizing review
- Knowledge transfer and team enablement
The tools we migrate with.
Migrations that
actually worked.
A regional bank needed to migrate their core banking platform — a 15-year-old on-premises system processing 2.4M daily transactions — to AWS. Previous migration attempt by a different vendor had been abandoned after six months.
We started with a 3-week assessment that revealed 47 undocumented integrations the previous vendor had missed. Designed a phased migration using CDC replication for the Oracle database, ran parallel environments for 8 weeks of validation, and orchestrated a 4-hour Sunday morning cutover.
4-hour cutover. Zero transaction failures. 38% infrastructure cost reduction. Regulatory approval obtained before cutover. The platform now handles 3× peak load with zero manual scaling.
A hospital network with 14 applications containing PHI needed to migrate to Azure. HIPAA compliance, data residency, and the BAA requirement made this more complex than a typical workload migration.
We mapped every PHI data flow before touching any infrastructure. Designed a HIPAA-compliant Azure landing zone with appropriate encryption, audit logging, and access controls. Validated compliance posture with independent security audit before cutover.
Migration completed on schedule. Zero PHI exposure events. HIPAA audit completed and passed. 41% reduction in infrastructure management overhead. Clinical staff noticed no service interruption.
A logistics company with 200+ vendors wanted to move from a single on-premises data center to a multi-cloud architecture — primary workloads to AWS, DR on Azure — to eliminate single points of failure.
Designed a multi-cloud architecture using Terraform for consistent IaC across both providers. Implemented cloud-agnostic application layer with abstracted cloud services. Built automated failover testing that runs weekly.
Multi-cloud architecture live in 14 weeks. Automated weekly DR drills passing. RPO reduced from 24 hours to 4 hours. RTO reduced from 8 hours to 45 minutes. 29% blended cloud cost reduction.
