Cloud computing means using computing resources, such as servers, storage, databases and software, over the internet instead of owning and running them yourself. You rent what you need and pay for what you use, much like electricity from the grid.
You already use the cloud: email, online file storage, video calls and streaming services all run on remote servers.
The main service models are Infrastructure as a Service (IaaS), where you rent virtual servers and storage; Platform as a Service (PaaS), where a provider supplies a ready environment to build and run applications; and Software as a Service (SaaS), where you simply use finished software through a browser, such as accounting or CRM tools.
Benefits for businesses include lower upfront costs, easy scaling during busy periods, access from anywhere, and professional backup and security tooling. Small teams can use tools that once required a large IT department.
There are trade-offs. Costs can grow if usage is not monitored, you depend on the provider and your internet connection, and moving data between providers can be difficult. Security is a shared responsibility: the provider secures the infrastructure, but you must manage strong passwords, access rights and configuration.
Before moving to the cloud, list what you need, start with one workload such as backups or email, check where your data is stored and which rules apply to your industry or country, and set a budget with alerts.
