Cloud means that merchants do not have to invest into building or maintaining costly infrastructure, such as setting up and hosting your own servers. Instead, merchants can focus on client-facing features such as website design and move quickly with getting the online store launched. The trade-off with cloud solutions is that some features or customizations may not be available on a specific platform (and you won’t be able to tweak the code yourself) and that an online shop’s data is stored in the platform’s cloud servers, rather than chosen by a merchant.
