Dynamic determination of memory requirements for function as a service multi-invocation flows

A system comprising a processor, memory accessible by the processor, computer program instructions stored in the memory and executable by the processor, and data stored in the memory and accessible by the processor to perform:

• selecting, at the computer system, a plurality of sample invocations of functions as a service from a larger plurality of invocations of functions as a service to be executed;
• submitting for execution, from the computer system to a cloud service, the plurality of sample invocations of functions as a service and, for each sample invocation, submitting a specification of a memory size to be used for execution of each sample invocation;
• determining, at the computer system, whether the specification of the memory size to be used for execution of each sample invocation results in unsuccessful execution of at least some of the plurality of sample invocations due to insufficient memory and, if so, adjusting the specification of the memory size for at least some of the sample invocations;
• and
• submitting for execution, from the computer system to a cloud service, at least those invocations in the larger plurality of invocations that were not included in the plurality of sample invocations.

A computer program product comprising a non-transitory computer readable storage having program instructions embodied therewith, the program instructions executable by a computer, to cause the computer to perform a method comprising:

• selecting, at the computer system, a plurality of sample invocations of functions as a service from a larger plurality of invocations of functions as a service to be executed;
• submitting for execution, from the computer system to a cloud service, the plurality of sample invocations of functions as a service and, for each sample invocation, submitting a specification of a memory size to be used for execution of each sample invocation;
• determining, at the computer system, whether the specification of the memory size to be used for execution of each sample invocation results in unsuccessful execution of at least some of the plurality of sample invocations due to insufficient memory and, if so, adjusting the specification of the memory size for at least some of the sample invocations;
• and
• submitting for execution, from the computer system to a cloud service, at least those invocations in the larger plurality of invocations that were not included in the plurality of sample invocations.
