What it is
Cloud computing is a model that offers compute resources like CPU, network, and disk capabilities on-demand over the internet. Cloud computing gives users the ability to access and use computing power in a remote physical location. Cloud providers like AWS, GCP, Azure, DigitalOcean, and others all offer third parties the ability to rent access to compute resources in multiple geographic locations.
Problem it addresses
Organizations traditionally faced two main problems when attempting to expand their use of computing power. They either acquire, support, design, and pay for facilities to host their physical servers and network or expand and maintain those facilities. Cloud computing allows organizations to outsource some portion of their computing needs to another organization.
How it helps
Cloud providers offer organizations the ability to rent compute resources on-demand and pay for usage. This allows for two major innovations: organizations can try things without wasting time planning and spending CAPEX on new physical infrastructure and they can scale as needed and on-demand. Cloud computing allows organizations to adopt as much or as little infrastructure as they need.
