AWS Migration: Migrating On-Premises Infrastructure to AWS
An AWS migration is not just lift-and-shift. Converting VMs into EC2 instances without a plan leads to higher costs and zero gains. We do it right.
AWS offers real advantages over on-premises: elasticity, global availability, and managed services that reduce operational effort. However, these benefits are only realized if the migration incorporates cloud-native architectural decisions rather than copying on-premises concepts to the cloud.
The most common challenges
Lift-and-shift generates more expensive cloud infrastructure than on-premises
Migrating a VM 1:1 as an EC2 instance means: 24/7 runtime, no auto-scaling, no managed services, and no rightsizing. This results in cloud infrastructure that costs more than the data center it replaced.
Lack of cost transparency surprises finance departments
AWS costs are dynamic and hard to predict without established cost management. For many teams, the first AWS bill after migration is an unpleasant surprise.
Security and compliance are neglected under migration pressure
IAM policies are often too permissive, security groups too open, and encryption unconfigured. This backfires during the next audit or security incident.
The CCsolutions approach
CCsolutions starts every AWS migration with a structured assessment: Which workloads benefit from managed services? What stays on-premises? Where does Kubernetes pay off over EC2? Migration only begins once the target architecture is defined.
The migration process runs in parallel: existing systems remain productive while the AWS environment is built and validated. Cutover happens gradually via blue-green routing, not as a high-risk "big-bang" weekend event.
AWS Cost Management, budgets, and CloudWatch alerts are configured from day one. IAM with least-privilege, KMS encryption, and CloudTrail auditing are built-in parts of the migration, not afterthoughts.

Frequently asked questions
When is AWS worth it over a private data center?
AWS is ideal when workloads vary significantly, global reaching is required, or the team prefers building applications over maintaining hardware. For stable, predictable workloads, on-premises might be cheaper, we clarify this during the assessment.
Can we keep parts on-premises?
Yes. Hybrid setups with AWS Direct Connect or VPN to existing data centers are common. Data with strict localization requirements stays on-premises, while elastic workloads move to AWS.
How long does a typical AWS migration take?
Small environments: 6-10 weeks. Medium environments: 3-5 months. Duration depends on architectural complexity and the degree of containerization.
