Determining virtual network function configurations

A method for configuring virtual network functions, implemented by a hardware processor, the method comprising:

• receiving a virtual network function specifying a particular function to be performed by at least one virtual machine;
• identifying a particular performance metric for the virtual network function;
• obtaining a test data set that includes input data for the virtual network function;
• determining, using the particular performance metric, the test data set, and a default resource configuration, a first infrastructure configuration specifying a value for each of a plurality of infrastructure options, each of the plurality of infrastructure options specifying a feature of the at least one virtual machine;
• and
• determining, using the particular performance metric, the test data set, and the first infrastructure configuration, a first resource configuration specifying a value for each of a plurality of virtualized hardware resources for the at least one virtual machine.

A non-transitory machine-readable storage medium encoded with instructions executable by a hardware processor of a computing device for configuring virtual network functions, the machine-readable storage medium comprising instructions to cause the hardware processor to:

• receive a virtual network function specifying a particular function to be performed by at least one virtual machine;
• identify a particular performance metric for the virtual network function;
• obtain a test data set that includes input data for the virtual network function;
• determine a first infrastructure configuration by iteratively adjusting and testing infrastructure configurations using the particular performance metric, a default resource configuration, and the test data set, each infrastructure configuration specifying a value for each of a plurality of infrastructure options, each of the plurality of infrastructure options specifying a feature of the at least one virtual machine;
• and
• determine a first resource configuration by iteratively adjusting and testing resource configurations using the particular performance metric, the first infrastructure configuration, and the test data set, each resource configuration specifying a value for each of a plurality of virtualized hardware resources for the at least one virtual machine.
