In a microservice environment, if multiple instances of the same pod are present, will separate classes be created for each instance or the class resource is read from a common place for both the instances?

I was thinking since Static Synchronized method locks the class level we can prevent race condition. Any input would be helpful.

CodePudding user response：

The 'static' or 'synchronized' keywords apply only for a single process. As soon as you run multiple instances it won't help, no matter if on the same machine, same container or different containers/pods or machines.
