Exposing control to enable interactive schedulers for cloud cluster orchestration systems

A system, comprising:

• a compute cluster comprising one or more nodes, each of the one or more nodes comprising at least one of a physical machine or a virtual machine;
• and
• placement and load balancing (PLB) logic executing on the compute cluster, the PLB logic being configured to:
• receive first data relating to a service executing on the compute cluster from a resource manager executing on the compute cluster via a first application programming interface (API) associated with the resource manager, the first data including state metadata collected by the resource manager from the compute cluster;
• receive second data relating to the service from the service via a second API that is different from the first API and unassociated with the resource manager, the second data including custom metrics associated with the service;
• determine whether a remediation action related to at least one of placement or load balancing is indicated based on the first data and the second data;
• and
• in response to determining that the remediation action is indicated, executing the remediation action at least in part by sending a command to the resource manager to execute the remediation action.

A method in placement load and balance (PLB) logic of a compute cluster, comprising:

• receiving first data relating to a service executing on the compute cluster from a resource manager executing on the compute cluster via a first application programming interface (API) associated with the resource manager, the first data including state metadata collected by the resource manager from the compute cluster;
• receiving second data relating to the service from the service via a second API that is different from the first API and unassociated with the resource manager, the second data including custom metrics associated with the service;
• determining whether a remediation action related to at least one of placement or load balancing is indicated based on the first data and the second data;
• and
• in response to determining that the remediation action is indicated, executing the remediation action at least in part by sending a command to the resource manager to execute the remediation action.

A computer-readable storage medium having program code recorded thereon that when executed by at least one processor causes the at least one processor to perform a method in placement load and balance (PLB) logic of a compute cluster, the method comprising:

• receiving first data relating to a service executing on the compute cluster from a resource manager executing on the compute cluster via a first application programming interface (API) associated with the resource manager, the first data including state metadata collected by the resource manager from the compute cluster;
• receiving second data relating to the service from the service via a second API that is different from the first API and unassociated with the resource manager, the second data including custom metrics associated with the service;
• determining whether a remediation action related to at least one of placement or load balancing is indicated based on the first data and the second data;
• and
• in response to determining that the remediation action is indicated, executing the remediation action at least in part by sending a command to the resource manager to execute the remediation action.
