Cloud Migration to AWS

Move from on-premise, Azure, GCP, or legacy hosting to AWS without the lift-and-pray panic with discovery, dependency mapping, landing zone setup, and phased cutover.

What is cloud migration to AWS?

Planned migration. Phased cutover. Rollback at every step.

Cloud migration to AWS is the process of moving workloads from on-premise servers, another cloud provider (Azure, GCP), or legacy hosting platforms (Heroku, DigitalOcean) to AWS. A production-grade migration is not a copy-paste of VMs to EC2. It starts with workload discovery and dependency mapping to understand what moves when and in what order, followed by an AWS landing zone setup (multi-account, VPC, Transit Gateway, security baseline), a phased migration with rollback plans for each wave, and the day-one operations foundation (monitoring, runbooks, backups, DR configuration) that prevents the post-migration fire drill. Forged Concepts has migrated on-premise environments and workloads from other cloud providers to AWS. Nothing moves to production until it has been validated in staging, monitored, and has a documented rollback plan.

How we work

Five phases from discovery to day-one operations.

1

Discovery: workload inventory, dependency mapping, 6 R's classification

We audit every workload in the source environment: compute, storage, databases, network dependencies, inter-service calls, and external integrations. Every workload is categorized by migration strategy and ordered by migration sequence based on dependencies.

2

Landing zone: multi-account AWS setup, VPC, Transit Gateway, security baseline

Before any workload moves, we build the AWS foundation AWS Organizations, Control Tower, account structure, VPC networking with public and private subnets, IAM baselines, centralized CloudTrail logging, and SCPs that enforce guardrails across every account.

3

Network & connectivity: Direct Connect or VPN, private subnets, routing

Transit Gateway for multi-VPC connectivity replacing the unmanageable mesh of VPC peering connections. Direct Connect or Site-to-Site VPN for hybrid connectivity during migration, when on-premise workloads still need to reach services already on AWS.

4

Phased migration: wave-by-wave cutover with rollback plans, DMS for databases

Workloads migrate in priority order from the dependency map. Each workload is deployed and validated in staging before the production window. Blue/green traffic switching via Route 53 weighted routing means rollback is a DNS change, not a crisis.

5

Day-one ops: monitoring, alerting, runbooks, DR configuration

CloudWatch alarms for every migrated service, dashboards for cross-service visibility, runbooks for every critical operational procedure, and DR tested in a tabletop exercise before go-live. You don't discover DR doesn't work during a real incident.

Migration strategy

The 6 R's of cloud migration.

Strategy What it means Forged Concepts position
Rehost Move as-is to EC2 Used sparingly only when speed is critical and modernization follows in the next phase.
Replatform Move with optimization (e.g., self-managed DB → RDS) Most common starting point preserves the application while improving the infrastructure.
Refactor Rearchitect for cloud-native (ECS, Lambda, managed services) When ROI justifies it, not applied by default to every workload.
Repurchase Switch to a SaaS alternative When the workload is commoditized and a SaaS alternative eliminates operational overhead.
Retire Decommission the workload Always audited during discovery. Unused workloads don't migrate.
Retain Leave on-premise for now When migration risk outweighs benefit for the current phase.

Most Forged Concepts migrations land primarily in Replatform and Refactor. Pure lift-and-shift (Rehost) means inheriting on-premise operational debt in a cloud billing model which is usually worse than staying put.

Source platforms

Where we migrate from.

On-premise

Bare metal or VMware/OpenStack private cloud. Workloads assessed for lift or modernization. Networking bridged with Site-to-Site VPN or Direct Connect during transition.

Azure

Azure VNets → AWS VPCs, Azure SQL → RDS, Azure App Service → ECS or Lambda, Azure AD → IAM Identity Center. IAM and networking models differ significantly between platforms.

GCP

GCP VPCs → AWS VPCs, Cloud SQL → RDS, Cloud Run → ECS Fargate, GKE → EKS. GCP service accounts → AWS IAM roles.

Heroku

Container-based workloads → ECS Fargate. Heroku Postgres → RDS. Add-ons evaluated for AWS managed service equivalents.

DigitalOcean

Droplets → EC2, Managed Databases → RDS, Spaces → S3, App Platform workloads → ECS or Lambda.

Each source platform has distinct networking, database, and compute considerations. A migration plan written for on-premise does not translate directly to Azure or GCP the source platform shapes the dependency map and the translation patterns.

Migration timeline

How long does a cloud migration take?

Simple

2–6 weeks

Under 10 workloads, single source account, minimal compliance requirements.

Mid-complexity

2–4 months

10–50 workloads, multi-account source, shared databases, compliance requirements.

Full environment

4–9 months

50+ workloads, legacy databases, HIPAA or SOC 2, hybrid Direct Connect.

The longest phase is typically discovery and dependency mapping rushing it is the most common cause of migration problems. The actual cutover of a well-planned workload can take days, not weeks.

FAQ

Common questions about migrating to AWS.

How long does a cloud migration to AWS take?

A simple migration (1–3 workloads, minimal dependencies) typically takes 2–6 weeks. A mid-complexity migration (5–15 workloads, shared databases, compliance requirements) typically takes 2–4 months. A full environment migration (50+ workloads, multiple databases, regulatory compliance) typically takes 4–9 months. Forged Concepts structures migrations in waves so that business-critical systems migrate last and always have a tested rollback plan.

What is an AWS landing zone?

An AWS landing zone is the multi-account foundation for your AWS environment a management account, separate accounts for production, staging, and development, VPC networking in each account, centralized CloudTrail logging, Security Hub, and the IAM and SCP guardrails that enforce the security baseline across all accounts. AWS Control Tower automates landing zone setup. Forged Concepts configures the landing zone as the first step of every migration it's the foundation that everything else builds on.

What is AWS Transit Gateway?

AWS Transit Gateway is a network hub that connects multiple VPCs and on-premise networks through a single gateway instead of creating a mesh of VPC peering connections (which doesn't scale), you connect each VPC to the Transit Gateway and routing is managed centrally. With N VPCs, peering requires N×(N-1)/2 connections; Transit Gateway requires N connections. Forged Concepts uses Transit Gateway for all multi-account environments with shared services (databases, CI/CD, monitoring) that need cross-VPC access.

What is the difference between RTO and RPO?

RTO (Recovery Time Objective) is the maximum time your business can tolerate being without a system after a failure "we need to be back up within 4 hours." RPO (Recovery Point Objective) is the maximum data loss your business can tolerate "we can lose at most 15 minutes of transaction data." AWS migration planning includes defining RTO and RPO targets for each workload, then selecting the backup and DR strategy that meets them Multi-AZ for low RTO, cross-region replication for near-zero RPO.

Can you migrate from Azure or GCP to AWS?

Yes. Forged Concepts has migrated workloads from Azure and GCP to AWS. The process is similar to an on-premise migration: discovery, landing zone setup, networking (VPN or Direct Connect), phased migration, and post-migration optimization. Azure-to-AWS migrations often involve converting Azure-specific services (Azure Blob → S3, Azure SQL → RDS, Azure Functions → Lambda) to their AWS equivalents.

What is a phased migration?

A phased migration moves workloads to AWS in waves rather than all at once. Each wave: one or more workloads are migrated, tested in AWS, and validated under production traffic before the next wave begins. Critical systems migrate last, after the team has built confidence through smaller migrations. Each wave has a documented rollback plan so that if anything goes wrong, traffic can be routed back to the original environment within minutes.

Do you handle database migrations?

Yes. Forged Concepts uses AWS Database Migration Service (DMS) for database migrations DMS replicates the source database continuously while your migration runs, minimizing downtime to a final cutover window of minutes rather than hours. For large databases (1TB+), DMS is paired with AWS Snowball Edge for the initial bulk transfer.

What is AWS Direct Connect?

AWS Direct Connect is a dedicated network connection between your on-premise data center and AWS bypassing the public internet. It provides consistent bandwidth, lower latency, and lower egress costs compared to VPN connections. Direct Connect is recommended for large data transfers during migration (to avoid egress costs), for latency-sensitive hybrid architectures, and for environments where public internet connectivity is not acceptable for compliance reasons.

What happens after the migration is complete?

Post-migration, Forged Concepts establishes the day-one operations foundation: CloudWatch dashboards and alerting, runbooks for critical services, DR configuration and backup validation, cost tagging and budget alerts, and a 30-day monitoring period with active support. Clients can then transition to a managed services engagement for ongoing operations or take full ownership of the environment.
