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. thanks, Yi Tao
