Actually, https://controlplane.com provides 99.999% availability SLA. The reason it is able to do so is because it distributes your containerized workloads across multiple regions on multiple clouds (you pick the regions and clouds). You can have a single region or 200 regions - with the same effort. It then charges you by the millicore (1,000th of a vCPU core) for exactly what your app uses. It gives you metrics, logging, tracing, alerting, secrets management, service discovery, auto-TLS and you can trivially use your own domain name. You get the power of the hyper-scalers with the ease of use of Heroku. The best part is that it lets you mix-n-match ALL/ANY service from any cloud in your code without you having to deal with credentials! Meaning you can use S3, DynamoDB, RDS, Big Query, Big Table, Cosmos DB, etc. - across AWS, GCP and Azure and you can even run your code on-premises or on ANY providers such as Linode, Hetzner, Contabo, Equinix, Oracle, etc. In short - it is the "non-toy" way to run your code when failure is not an option, but at a ridiculously low cost.
