Details

  • Analyzed approximately 3.5 million communication logs collected via AWS Application Discovery Service (ADS) using an LLM-based tool to identify dependencies and communication patterns not documented
  • Determined that Windows Server and SQL Server licenses were dependent on physical servers, making BYOL impossible, and selected AWS-provided AMIs that include licenses

  • Configured a centralized network security architecture using AWS Transit Gateway and Gateway Load Balancer (GWLB)
  • Migrated the VDI environment to Amazon WorkSpaces and established a security audit system through CloudTrail
  • Performed Lift & Shift migration using AWS Transform MGN, verifying the feasibility of migration while maintaining firewall policies and the IP address scheme
  • ADS will no longer be available to new customers starting November 7, 2025, but existing users can continue to use it
