Migration & Landing Zones

Moving workloads to the cloud, or restructuring a disorganized existing environment, requires a rigorous architectural foundation. A poorly planned migration often results in a “lift and shift” of legacy technical debt, leading to inflated costs and operational friction. We design and implement secure, scalable Landing Zones that serve as the structural framework for your entire cloud footprint.

The core of a successful Landing Zone is a deliberate multi-account strategy. We structure Organization Units (OUs) to reflect logical boundaries of security and billing, enforcing baseline governance through Service Control Policies (SCPs). This account topology is paired with a strictly defined IAM boundary architecture, ensuring the principle of least privilege is applied uniformly across development, staging, and production environments.

Network topology is equally critical. We design robust hub-and-spoke or mesh networks using Transit Gateway or Cloud Interconnect, ensuring secure, high-bandwidth connectivity between on-premises data centers and cloud VPCs. We resolve complex DNS architecture challenges to ensure reliable internal resolution across environments.

For the migration itself, we apply the 6R framework (rehost, replatform, refactor, repurchase, retain, retire) systematically. We begin with thorough workload discovery and dependency mapping to group applications into logical migration waves. This phased approach minimizes disruption and allows engineering teams to validate performance and security at each step of the migration process.
