A half to a whole GB of memory is sufficient during the development stage, depending on the size of the shop.
Production phase – quiet shops:
If you host shops without all that many visitors, 1024 MB is usually enough for the first shop, with 256M to 384M for each additional shop.
Production phase – busy shops:
It is usually best to host busier shops on their own VPS. In terms of size, it is usually sufficient to begin with an environment having between 1 and 2 GB for several hundred visitors per day. When the shop becomes busier, you will usually need between 4 and 8G and sometimes more. You can always contact us for advice about caching and other optimisation possibilities.
