Scale multi-tenant SaaS with per-tenant version pinning using Amazon CloudFront
Multi-tenant SaaS providers often need to control which application version each tenant runs, a practice called per-tenant version pinning, so they can roll out new releases incrementally and move tenants between versions without downtime and manual changes. A common approach is to configure the Application Load Balancer with hostname-based routing rules, but this doesn’t scale. [...]
