Traffic optimization for multi-node applications

A non-transitory computer-readable storage medium that includes a set of instructions which, in response to execution by a processor of a host, cause the processor to perform a method of traffic optimization for a multi-node application implemented by at least a first virtualized computing instance, a second virtualized computing instance and a third virtualized computing instance in a virtualized computing environment, wherein the method comprises:

• detecting, from the first virtualized computing instance supported by the host, a packet that includes header information identifying the second virtualized computing instance as a destination;
• identifying that the first virtualized computing instance and second virtualized computing instance are configured to perform respective first role and second role to implement the multi-node application;
• based on one or more optimization factors, selecting the third virtualized computing instance that is also configured to perform the second role to replace the second virtualized computing instance;
• modifying the header information of the packet to identify the third virtualized computing instance as the destination;
• and
• sending the packet with modified header information to the third virtualized computing instance.

A host configured to traffic optimization for a multi-node application implemented by at least a first virtualized computing instance, a second virtualized computing instance and a third virtualized computing instance in a virtualized computing environment, wherein the host comprises:

• a processor;
• and
• a non-transitory computer-readable medium having stored thereon instructions that, when executed by the processor, cause the processor to support the first virtualized computing instance, and perform the following:
• detect, from the first virtualized computing instance, a packet that includes header information identifying the second virtualized computing instance as a destination;
• identify that the first virtualized computing instance and second virtualized computing instance are configured to perform respective first role and second role to implement the multi-node application;
• based on one or more optimization factors, select the third virtualized computing instance that is also configured to perform the second role to replace the second virtualized computing instance;
• modify the header information of the packet to identify the third virtualized computing instance as the destination;
• and
• send the packet with modified header information to the third virtualized computing instance.
