Thank you for your reply.


The scenario is the function computing of the public

cloud. Each instance of function computing will be

allocated about 0.1 core cpu and 100M memory. On

a high-end server, for example, 104 cores and 384G,

it is normal to create hundreds of containers at the

same time if burst of requests comes.
