2. Platform as Service – PaaS
3. Software as Service – SaaS
Benefits of Cloud Computing:
Flexible & Adjustable: It allows for changable programs and applications, that are customizable, while allowing the owners control over the core code.
Software Multitenancy: Cloud Computing software provides an opportunity to provide personalized applications and portals to several customers or tenants.
Scalability: Cloud computing applications makes it essential that software functions across every device and integrates with other applications.
Reliability: Since it is hosted by a third party, businesses and other users have greater assurance of reliability, and when there are problems, easy access to customer support. When the problems arise, it is easy to access customer support.
