Cloud services are infrastructure, platforms, or software that are hosted by third-party providers and made available to users through the internet.

There are three main types of as-a-Service solutions: IaaS, PaaS, and SaaS. Each facilitates the flow of user data from front-end clients through the internet, to the cloud service provider’s systems, and back—but vary by what’s provided.

The term “cloud services” refers to a wide range of services delivered on demand to companies and customers over the internet. These services are designed to provide easy, affordable access to applications and resources, without the need for internal infrastructure or hardware. From checking email to collaborating on documents, most employees use cloud services throughout the workday, whether they’re aware of it or not.

Cloud services are fully managed by cloud computing vendors and service providers. They’re made available to customers from the providers’ servers, so there’s no need for a company to host applications on its own on-premises servers.
