What do you mean? Aside from deployed codebase, I don't quite see it - if you need memory, allocate - start small/empty for any datastructure. If managed/gc setup delallocating is inherent, so no special case about freeing memory. Don't create unnecessary threads - but even then dormant threads are very cheap nowadays. There you go - it scales vertically nicely, make sure the application can scale horizontally (say, partitioning by user) and you have all the benefits with close to no drawbacks
