PaaS technologies
PaaS includes multiple underlying cloud infrastructure components, including servers, networking equipment, operating systems, storage services, middleware, and databases.
All of these technology offerings are owned, operated, configured, and maintained by the service providers. These fully managed infrastructure services not only relieve the customer of the IT administrative burden, but also present an attractive financial argument for customers. They can avoid having to lay out investments in these foundational IT components that they might not be able to use to the fullest extent possible.
PaaS also includes resources such as development tools, programming languages, libraries, database management systems, and other tools from the cloud provider.
