05.2 Cloud Migration Project
Before/after architecture, technologies used, and measurable results from a cloud migration engagement. (Detail to be added.)
Media & Entertainment CDN Migration: Alibaba Cloud CDN → Huawei Cloud CDN
Before Architecture: Images and static assets from multiple domains were delivered through Alibaba Cloud CDN, with origin servers hosted on local/on-premises infrastructure. The setup included cache rules, HTTPS/SSL certificates, hotlink protection (referer/URL authentication), IP blacklist/whitelist, and logging.
After Architecture: All domains are served through Huawei Cloud CDN, with the origin remaining on-premises. Huawei OBS is used for backup and log storage. All configurations above were migrated to Huawei Cloud CDN. Cutover was performed in a single step via CNAME/DNS change, backed by a rollback plan.
Technologies Used: Huawei Cloud CDN, Huawei OBS, Alibaba Cloud CDN (source), CNAME/DNS, SSL/TLS, referer & URL authentication.
Outcome / Impact: Migration completed in 2 weeks with zero downtime. The project addressed three business goals: cost efficiency, improved performance, and vendor consolidation onto a single platform. The cutover was safeguarded by a rollback plan.
