Safer Deploys, Instant Rollback, and Live Scaling for FoundryDB Apps

App Hosting launched with apps served over HTTPS, attached to your managed databases on a private network, and redeployed with a blue/green flip that keeps the old container serving if the new one fails to start. That covered shipping. It did not cover the day a deploy goes wrong, the day a deploy goes wrong and your container starts but never becomes ready, or the day the app outgrows its plan under load.

Four features shipped since launch close those gaps. Every deploy is now an immutable revision you can roll back to in one request. Health checks gate the blue/green cutover so a container that comes up broken never takes traffic. Vertical scaling is a live hot resize with no reboot. And CPU and memory alerts now surface on the app detail page. Here is each one.
