Cloud computing is the delivery of computing resources, such as servers, storage, databases, networking and software, over the internet on demand. Instead of buying and running their own equipment, organisations rent capacity from a provider and typically pay for what they use.
Providers operate large data centres and divide their hardware into virtual resources that customers can start, resize or stop within minutes. Services are commonly grouped into infrastructure as a service, where you manage virtual machines, platform as a service, where the provider also manages the runtime, and software as a service, where you simply use an application. Resources can be placed in specific geographic regions.
Retailers and venues use the cloud to host ecommerce sites and apps, run cloud-based POS and inventory systems, store backups, process analytics and handle sudden traffic spikes such as sale events without owning surplus hardware.
Common pitfalls include unmanaged costs when resources are left running, weak access controls or misconfigured storage that exposes data, and assuming the provider handles all security. Under the shared responsibility model the provider secures the underlying infrastructure while the customer secures their own configuration, accounts and data. Planning for data location, backups and exit options also avoids surprises later.
Cloud computing matters because it lowers upfront costs, scales with demand and allows small and mid-sized retailers to use capabilities once available only to large enterprises. RetailCare offers cloud services built on AWS.
