You could do this by merely keeping backing data servers running all the prison term, fix to switch into product mode at a consequence ’ second notice. But that would be costly, because it would mean keeping accompaniment servers running at full capacity all the meter. A more efficient approach would be to keep accompaniment data waiter images on hand, then spin up newly virtual servers in the cloud based on those images when you need them.
