Edge functions at an edge location of a content delivery network (CDN) may use APIs of a datastore engine in order to read / write or create / delete local tables at the edge location. Data may be accumulated in the local tables and the new data may be used to enhance decision at the edge. Some of the local tables may be initially populated from a back-end database. This allows the functions to modify the data from the back-end database, without affecting the actual source data at the back-end database (modifications to local tables remain local to the edge location).

Systems and methods for locating microserver nodes in proximity to edge devices using georouting. Microservers automatically form a global peer-to-peer network to serve edge functions and content to edge devices. Edge devices use HyperText Transfer Protocol (HTTP) to execute serverless functions or otherwise retrieve data from edge nodes and / or microservers located in proximity to the HTTP client. The cloud platform locates the nearest edge node and / or microserver. Edge devices georoute HTTP requests to the nearest edge node and / or microserver. Serverless functions are implemented in secure, isolated environments using a blockchain.
