The good, the bad, and the ugly of migrating hundreds of legacy applications to a cloud native platform
This document discusses Syncier's approach to migrating 152 legacy applications from a traditional platform to a cloud native platform within 17 months. Key aspects included: 1) All applications were containerized using a 12-factor app approach and migrated to production on the cloud platform. 2) The applications were modernized and security hardened during the migration process. 3) The migration provided benefits like higher availability, more agile development teams, and a strong business case. The document then discusses perspectives from an architect, project manager, and developer on the migration process. It emphasizes an emergent design approach, industrialization of the migration through training and support, and transparency throughout the project.
