Dynamic network routing based on application load

A system associated with a controller of a network, the system comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media storing instructions that, when executed, cause the one or more processors to perform operations comprising:
• receiving, from a client device, a request to route traffic associated with an application through the network, the network disposed between the client device and different cloud-service provider zones in which different instances of the application are running;
• receiving load information associated with the different instances of the application in the different cloud-service provider zones, the load information including at least:
• first load information associated with a first instance of the application hosted on first scalable resources of a first cloud-service provider zone;
• and
• second load information associated with a second instance of the application hosted on second scalable resources of a second cloud-service provider zone;
• determining, based at least in part on the load information, that the first instance of the application is less constrained than the second instance of the application;
• and
• based at least in part on the first instance of the application being less constrained than the second instance of the application, causing one or more network nodes of the network to steer the traffic through the network to the first instance of the application hosted in the first cloud-service provider zone.

One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving, from a client device and at a controller of a network, a request to route traffic through the network between the client device and an application;
• receiving, at the controller, load information metrics associated with different instances of the application hosted in different cloud-service provider zones, the load information metrics including at least:
• a first load information metric associated with a first instance of the application hosted in a first cloud-service provider zone, the first load information metric calculated based at least in part on a first number of replicas of the application in the first cloud-service provider zone and a first infrastructure utilization of the first cloud-service provider zone;
• and
• a second load information metric associated with a second instance of the application hosted in a second cloud-service provider zone, the second load information metric calculated based at least in part on a second number of replicas of the application in the second cloud-service provider zone and a second infrastructure utilization of the second cloud-service provider zone;
• determining, at the controller and based at least in part on the load information metrics, that the first instance of the application is less constrained than the second instance of the application;
• and
• based at least in part on the first instance of the application being less constrained than the second instance of the application, causing, by the controller, the traffic to be sent through the network to the first instance of the application hosted in the first cloud-service provider zone.
