Public cloud hosting is offered by the world's largest IT companies through the operation of millions of rackmount web servers simultaneously across multiple international data center locations. Public cloud hosting includes Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS) products for businesses, government organizations, education, non-profits, & independent web publishers. Large corporations can outsource their entire data center operations to a public cloud provider to save money on the costs of in-house IT departments.
Public cloud hosting platforms make various elastic web servers, Container-as-a-Service (CaaS), Kubernetes, and Database-as-a-Service (DBaaS) products available to developers to build new software applications. Public cloud hosting is used for websites, mobile apps, & other data center requirements for complex organizations of any size, from small business to the largest companies in the Fortune 500. The ability to scale to support enterprise levels of web traffic in production is considered a key aspect of public cloud hosting.
