[Seaside] Multiple applications in multiple images?

I have found a solution for myself to load-balance a single seaside
application with multiple images.

I use 10 squeak instances with 10 separate images (I thought separate
images would be good to be able to easily upgrade to a new version of
the image or also squeak without interrupting the web service,
replacing the images one by one)

Now the next step is managing multiple applications. I am wondering if
it would be wiser to put each application into its own image, this
would make the amount of images on the server grow, but each
application has its own image and this is maybe easier to maintain (on

So the config is like this:

- apache2 with reverse proxy
- a load balancer (e.g. HAProxy)
- solution A:
    10 squeak instances and images and each of them containing
    application 1 and application 2
- solution B
    10 squeak instances and images for application 1
    10 squeak instances and images for application 2

Maybe in solution B it could be necessary to reduce the absolute
amount of squeak instances, maybe to 7 + 7, depending on the machine
memory. Or use more servers.

I post this before trying out multiple applications with load balancing.

Do you have any thoughts or recommendations?
