What is cloud computing?

Commonly referred to as simply “the cloud,” cloud computing is the delivery of computing resources over the internet—things like applications, servers, storage, software, and networking.

Cloud computing powers many of the services you use every day, including email, video streaming, and file storage. It’s also transforming the way companies of all sizes are doing business. More companies are seeing the value of shifting away from the traditional on-premises data center model and offloading some of their computing resources onto the cloud.

Benefits of cloud computing

Subscribing to cloud services can be much more cost effective than investing in your own data centers and hardware. You can better control costs by paying only for what you use—and you gain agility by being able to scale resources up or down on demand.

Cloud computing also frees up IT from having to manage day-to-day tasks, like server maintenance and software patches, enabling them to play a more strategic role focused on achieving business outcomes.

Types of cloud services

Infrastructure-as-a-Service (IaaS) is when you rent infrastructure—servers, storage, networking firewalls, etc.—from a cloud provider. With IaaS, you’re using the provider’s resources, paying as you go, instead of investing in your own.

Software-as-a-Service (SaaS) refers to the delivery of software applications over the internet, usually as a subscription. Cloud providers host the application and underlying infrastructure, and take care of updates and patches. People usually connect to these apps over a web browser.
