Abstract: Techniques implemented by a cloud computing system for providing fallback capacity providers to ensure that infrastructure capacity required to run containerized services is available despite primary capacity providers experiencing a failure. Cloud providers offer container-management services that automate the management and scaling of containerized services of users. The container-management services are supported by capacity providers that manage the computing infrastructure on which the containerized services run (e.g., servers, VMs, etc.). However, there are times when a capacity provider is unable to provision capacity for containerized services, such as due to a large scale failure. Rather than leaving capacity requests unserved, the container-management service designates a fallback capacity provider that acts as a failover for provisioning requested infrastructure capacity.
