Object storage is not a cloud drive: tier hot, warm, and cold data
Images, video, downloads, and backups have different access patterns. Lifecycle policy shapes long-term cost and recovery speed.

Cross-border latency is not solved by CDN alone
DNS, TLS, origin distance, cache hit rate, and dynamic API routing all shape first-load performance.

During site migration, old links and search indexing belong in the deployment plan
A new site does not retire old URLs automatically. Redirects, sitemaps, canonical links, and error pages matter.
