Method, apparatus, electronic device and readable storage medium for adjusting instance number

An electronic device, comprising:

• at least one processor;
• and
• a memory communicating with the at least one processor, wherein the memory stores instructions executable by the at least one processor, and the instructions, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• acquiring an actual performance index of a current time window;
• determining a theoretical instance number corresponding to the actual performance index;
• and
• requesting, in response to the theoretical instance number being greater than an instance creating upper limit of a current edge computing node, another edge computing node having an instance addition capability to jointly create an instance of a number equal to the theoretical instance number, wherein different edge computing nodes have different instance creating upper limits due to a performance difference.

A non-transitory computer readable storage medium storing computer instructions for causing a computer to perform operations comprising:

• acquiring an actual performance index of a current time window;
• determining a theoretical instance number corresponding to the actual performance index;
• and
• requesting, in response to the theoretical instance number being greater than an instance creating upper limit of a current edge computing node, another edge computing node having an instance addition capability to jointly create an instance of a number equal to the theoretical instance number, wherein different edge computing nodes have different instance creating upper limits due to a performance difference.
