Depends on a bunch of things including how your app is designed of course.
Most of the high end containers can be clustered to give you better
scalability without having to make some of those decisions yourself. By
deploying the app on multiple machines and letting the clustering software
do the load balancing, each machine can be better used.
When you start running multiple instances on a single machine, you start
competing for access to drives, CPU, memory and network access between
instances. Running in a cluster eliminates the competition on a single
machine and gives better overall performance.
Removing any statically deployed resources from the WO app helps scalability
tremendously.
