These resources include tools and applications like data storage, servers, databases, networking, and software. Rather than keeping files on a proprietary hard drive or local storage device, cloudbased storage makes it possible to save them to a remote database. As long as an electronic device has access to the web, it has access to the data and the software programs to run it. Cloud computing is a popular option for people and businesses for a number of reasons including cost savings, increased productivity, speed and efficiency, performance, and security. Types of Cloud Computing: Cloud computing is not a single piece of technology like a microchip or a cellphone. Rather, it's a system primarily comprised of three services: software-asaservice (SaaS), infrastructure-as-a-service (IaaS), and platform-as-a-service (PaaS). 1-Software-as-a-service (SaaS) : involves the licensure of a software application to customers. Licenses are typically provided through a payasyou-go model or on-demand. This type of system can be found in Microsoft Office's 365. 2-Infrastructure-as-a-service (IaaS): involves a method for delivering everything from operating systems to servers and storage through IPbased connectivity as part of an on-demand service. Clients can avoid the need to purchase software or servers, and instead procure these resources in an outsourced, on-demand service. Popular examples of the IaaS system include IBM Cloud and Microsoft Azure. 3-Platform-as-a-service (PaaS): is considered the most complex of the three layers of cloud-based computing. 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. This model includes platforms like Salesforce.com and Heroku. 6- Mobile platforms:
