The author of this text successfully migrated an e-commerce application from on-premise to cloud native using Next.js, GraphQL engine, PostgreSQL, and other frameworks. They replaced the original architecture with cloud native counterparts such as YugabyteDB, Hasura Cloud, and Vercel. The migration process involved three main lessons learned: PostgreSQL compatibility matters significantly, cloud native services are easy to switch to, and zero code changes are a myth. The author had to make some adjustments to their code to ensure proper functionality with the new software and services, but overall, the experience was smooth and relatively painless.
