Having a container per service level seems like an okay thing to me. > Memory resources, by their very nature, will be tougher to account when a > single database/app server services multiple clients and we can essentially > give up on that (taking the approach that only limited recharging can ever > be achieved). What exactly you mean by limited recharging? As said earlier, if there is big shared segment on a server then that can be charged to any single container. And in this case moving a task to different container may not fetch anything useful from memory accounting pov. > But cpu atleast is easy to charge correctly and since that will > also indirectly influence the requests for memory & I/O, its useful to allow > middleware to change the accounting base for a thread/task. > That is not true. It depends on IO size, memory foot print etc. etc. You can move a task to different container, but it will not be cheap. -rohit ------------------------------------------------------------------------- Using Tomcat but need to do more?
