AWS Cloud Migration for Enterprise & Mid-Market Companies
Wolk Inc delivers end-to-end AWS migrations: workload discovery, landing zone design, wave-based execution, and post-migration cost optimisation. Zero-downtime cutover strategy on every engagement, from single-application migrations to full data centre evacuations.

Which AWS Migration Approach Is Right for You?
Lift-and-Shift (Rehost)
Direct migration of existing servers and workloads to AWS EC2 or Lightsail with minimal modification. Fastest path to AWS. Best for applications with complex dependencies, tight deadlines, or where modernisation is planned as a second phase. Typically 4–8 weeks for a 20–50 server environment.
Re-Platform
Targeted modernisation during migration: move databases to RDS, container applications for ECS or EKS, shift to managed services (SQS, SNS, ElastiCache) without full re-architecture. Captures 30–50% more cloud efficiency than lift-and-shift with comparable migration effort.
Re-Architect (Cloud-Native)
Full re-design of application architecture to leverage AWS-native capabilities: serverless, event-driven microservices, managed data services, and multi-region active-active designs. Higher upfront effort, but delivers the largest long-term cost efficiency and operational simplicity gains.
Landing Zone & Governance First
For enterprises migrating 50+ workloads, Wolk Inc designs the AWS landing zone — multi-account Organisation structure, IAM permission boundaries, SCPs, centralized logging, and network architecture — before migrating any workloads. This eliminates the technical debt of retrofitting governance after migration.
How a Wolk Inc AWS Migration Works
Discovery & Workload Inventory
Application inventory, dependency mapping, licensing analysis, and TCO comparison. Output: migration wave plan with workload prioritisation, recommended migration strategy per application, and cost projection for the migrated state.
Landing Zone Design
AWS Organisation and account structure design, VPC architecture, IAM frameworks, SCPs, centralized CloudTrail and GuardDuty, and networking (Transit Gateway or VPC peering) before any workload migrations begin.
Wave Execution
Workloads migrated in prioritised waves. Each wave includes pre-migration testing, parallel-run validation period, cutover window planning, and rollback capability until the old environment is decommissioned.
Optimisation & Handoff
Post-migration cost optimisation (right-sizing, reserved instance planning, Savings Plans), runbook documentation, team training, and optional ongoing managed services for continued cost and reliability governance.
Landing Zone First. Zero Downtime. Documented Handoff.
AWS Migration Questions
How long does an AWS migration take?▾
Migration timelines depend on the number of workloads, their complexity, and the chosen migration strategy. A single application lift-and-shift can be completed in 2–4 weeks. A 20–50 server environment with re-platforming typically runs 8–16 weeks. A full enterprise migration of 100+ workloads with landing zone design typically runs 6–18 months across multiple waves. Wolk Inc delivers a detailed migration wave plan with timelines after the discovery phase.
How does Wolk Inc ensure zero downtime during AWS cutover?▾
Wolk Inc designs cutovers with parallel-run periods: the new AWS environment runs alongside the old environment, handling test traffic before production cutover. DNS-based traffic switching (Route 53 weighted routing or health check failover) allows instant rollback if issues are detected. Database migrations use AWS DMS for live replication with minimal downtime cutover windows. Most production cutovers are completed in a 30-minute maintenance window.
What AWS services does Wolk Inc use for migration?▾
Wolk Inc uses AWS MGN (Application Migration Service) for server replication, AWS DMS for database migration, AWS Schema Conversion Tool for database engine changes, CloudFormation/CDK/Terraform for infrastructure-as-code provisioning, and AWS Control Tower or custom landing zone implementations for governance. The specific toolset is selected based on your source environment, target architecture, and team preferences.
Does Wolk Inc handle AWS cost optimisation after migration?▾
Yes. Post-migration optimisation is included in Wolk Inc AWS migration engagements as a standard phase. This includes instance right-sizing based on CloudWatch utilisation data, EC2 Savings Plans and Reserved Instance purchase recommendations, S3 lifecycle policy configuration, and data transfer cost analysis. Most clients see 30–50% cost reduction from the unoptimised lift-and-shift state after the optimisation phase.
Does Wolk Inc design the AWS landing zone, or just migrate workloads?▾
Wolk Inc designs the landing zone first — multi-account Organisation structure, SCPs, centralised security services, and network architecture — before migrating any workloads. This approach prevents the expensive and risky process of retrofitting governance into an already-populated environment. For clients using AWS Control Tower, Wolk Inc implements and customises the Control Tower landing zone with account vending, permission sets, and baseline security controls.
