Adaptive traffic forwarding over multiple connectivity services

A non-transitory computer-readable storage medium that includes a set of instructions which, in response to execution by a processor of a first computer system, cause the processor to perform a method of adaptive traffic forwarding, wherein the method comprises:

• monitoring metric information associated with at least a first connectivity service from multiple connectivity services that are connecting (a) the first computer system located in a first cloud environment at a first geographical site and (b) a second computer system located in a second cloud environment at a second geographical site;
• in response to determination that a condition for scaling up is satisfied based on the metric information,
• selecting, from a set of multiple flows associated with the first connectivity service, a subset that includes at least a first flow between a first endpoint located in the first cloud environment and a second endpoint located in the second cloud environment;
• and
• updating routing information to associate the subset with a second connectivity service from the multiple connectivity services;
• and
• in response to detecting egress packets associated with the first flow from the first endpoint, forwarding the egress packets towards the second computer system using the second connectivity service based on the updated routing information to cause the second computer system to forward the egress packets towards the second endpoint.

A first computer system, comprising:

• a processor;
• and
• a non-transitory computer-readable medium having stored thereon instructions that, when executed by the processor, cause the processor to perform the following:
• receiving, from a management entity, control information indicating that a condition for scaling up is satisfied based on metric information associated with at least a first connectivity service from multiple connectivity services that are connecting (a) the first computer system located in a first cloud environment at a first geographical site and (b) a second computer system located in a second cloud environment at a second geographical site;
• based on the control information, update routing information to associate a subset with a second connectivity service from the multiple connectivity services, wherein the subset is selected from a set of multiple flows associated with the first connectivity service, and includes a first flow between a first endpoint located in the first cloud environment and a second endpoint located in the second cloud environment;
• and
• in response to detecting egress packets associated with the first flow from the first endpoint, forward the egress packets towards the second computer system using the second connectivity service based on the updated routing information to cause the second computer system to forward the egress packets towards the second endpoint.
