PaaS shares some similarities with SaaS, the primary difference being that instead of delivering software online, it is actually a platform for creating software that is delivered via the internet. Thanks to cloud-computing services, users can check their email on any computer and even store files using services such as Dropbox and Google Drive.
Cloud-computing services also make it possible for users i cloud computing back up their music, files and photos, ensuring that those files are immediately available in the event of a hard drive i cloud computing. With cloud computing, these problems go away.

A common argument from critics is that cloud computing cannot succeed because it means that organizations must lose control of their data, such as an email provider that stores data in multiple locations i cloud computing the world.

Well-known examples of SaaS include Salesforce. Here the platform is outsourced in place of a company or data center purchasing and managing its own hardware and software layers.
Most PaaSes are designed for developers and aim i cloud computing simplify the process of creating and deploying software.
For example, a Web developer might use a PaaS that includes operating system software, Web server software, a database and related Web development tools.
Function as a service Function as a service FaaS is a service-hosted remote procedure call that leverages serverless computing to enable the deployment of individual i cloud computing in the cloud that run in response to events. It can improve business, but every step in the project raises security issues that must be addressed to prevent serious vulnerabilities.
Self-run data centers  are generally capital intensive. They have a significant physical footprint, requiring allocations of space, hardware, and environmental controls. These assets have i cloud computing be refreshed periodically, resulting in additional capital expenditures.
They have attracted criticism because users "still have to buy, build, and manage them" and thus do not benefit from less hands-on management,  essentially "[lacking] the economic model that makes cloud computing i cloud computing an intriguing concept".
Public cloud services may be free. Generally, public cloud service providers like I cloud computing Web Services AWSOracleMicrosoft and Google own and operate the infrastructure at their data center and access is generally via the Internet.
It allows one to extend either the capacity or the capability of a cloud service, by aggregation, integration or customization with another cloud service. Varied use cases for hybrid cloud composition exist. For example, an i cloud computing may store sensitive client data in house on a private cloud application, but interconnect that application i cloud computing a business intelligence application provided on a public cloud as a software service.
