Moving an application from one cloud to another is risky, and QA is often brought in too late. This whitepaper shows how QA can support a large-scale cloud migration from planning and architecture design through to post-migration monitoring, using a real AWS to GCP migration as the sample case. It covers the testing a migration needs, including web services, middleware, functional, integration, database, security, performance and DevOps testing, and why a fully working staging environment should be a top priority.
In the case study, the entire production traffic moved to GCP in a single night, and no end user reported data loss or functionality issues afterwards. Along the way, testing caught 100+ backend issues and close to 150 functionality issues before they could reach users.
