Amazon Workspaces is a fully managed, secure cloud desktop service by AWS that enables IT teams to provision Windows or Linux virtual desktops in minutes, eliminating hardware procurement and enabling global workforce access from any device.

The 6 Rs framework provides six pathways-Repurchase, Rehost, Replatform, Refactor, Retire, Retain-enabling tailored modernization strategies for different application types and business objectives.

Full modernization includes refactoring databases, updating application networks and libraries, customizing servers, integrating DevOps, and embedding enterprise-grade security.

Our Migration Factory approach combines automated tools, phased deployment strategies, and dedicated expertise to ensure business continuity with zero operational downtime.

Common challenges include technical debt and complex legacy code, data migration risks (ensuring data integrity and consistency), security vulnerabilities in outdated systems, skill gaps in modern technologies, resistance to organizational change, and high upfront costs.

Timelines vary significantly based on application complexity, portfolio size, and chosen strategy. Simple lift-and-shift migrations (Rehost) may take 3-6 months, while comprehensive refactoring or rearchitecting initiatives can span 12-24 months or longer.
