Serverless code service

A method for managing codes for elements in a digital twin of infrastructure, comprising:

• obtaining, by a code service executing on an edge computing device from a cloud container maintained by a cloud datacenter, a write lock;
• downloading, by the code service, a manifest for a master code database to update a local manifest of a code index database on the edge computing device;
• receiving, by the code service, one or more requests from an application to add, delete or modify codes for elements used in the digital twin;
• downloading any blocks affected by the request that are not already local from the master code database to the code index database;
• writing, by the code service, to the code index database to add, delete, or modify one or more blocks of the code index database, and recording such additions, deletions, or modifications to create an updated local manifest;
• uploading, by the code service, added or modified blocks to the master code database, and uploading the updated local manifest to replace the manifest in the cloud container;
• and
• releasing the write lock back to the cloud container.

An edge computing device configured to manage codes for elements in a digital twin of infrastructure, the edge computing device comprising:

• a processor;
• a memory coupled to the processor, the memory configured to maintain a code index database for storing a portion of a master code database of a cloud container, a local manifest for the code index database produced from a manifest in the cloud container, and software for a code service that when executed on the processor is operable to:
• service one or more requests from an application to verify a code to be used in the digital twin of infrastructure by downloading from the master code database to the code index database any blocks indicated in the local manifest that are required to read the code that are not already local in the code index database, reading the code index database, and supplying verification for the code from the code index database to the application;
• and
• service one or more requests from the application to add, delete, or modify codes for elements used in the digital twin by obtaining a write lock, downloading the manifest in the cloud container to update the local manifest, writing to the code index database to add, delete, or modify one or more blocks of the code index database and recording such additions, deletions, or modifications to create an updated local manifest, uploading added or modified blocks to the master code database and uploading the updated local manifest to replace the manifest in the cloud container, and releasing the write lock back to the cloud container.
