US Patent 11018965 Serverless function scaling

The present disclosure provides for systems and methods for dynamically managing a concurrency limit of a serverless function, in other words, a quantity of instances of a serverless function that may be concurrently executed. Performance metrics of the serverless function as it is implemented by services may be measured and compared against preconfigured thresholds. If the performance metrics meet the preconfigured thresholds, the concurrency limit of the serverless function may be increased. In some aspects, if one or more performance metrics fails to meet a respective preconfigured threshold, the concurrency limit of the serverless function may be decreased.
