标 题: how does AWS's auto scale work?
发信站: BBS 未名空间站 (Tue Apr 22 12:54:57 2014, 美东)
Suppose I launched an AWS instance, deployed my application (i.e., a Java
WAR). When a single instance is incapable of handling the heavy traffic, is
the AWS going to automatically duplicate the application to another instance
and redirect some traffic to the second instance? Here, I consider an "
instance" as a "server", but I'm not sure whether I'm correct.
Any advice is appreciated! | t****3

发帖数: 266 | 3 Thank you. Is the deployed application automatically copied to that
additional server? If that's the case, what if the content of the
application package changes in one server but not the other, following some
user operations (like a file is uploaded and stored relative to the
application context path?)

want to deploy new package to one server. I have not used AWS for few years
, you'd better check online doc to confirm. | q**q
