Cloud computing allows you to access hardware, software and complete cloud computing.
There are three types of cloud service: Infrastructure as a Service, Platform as a Service and Software as a Service. IaaS allows you to access computer hardware like storage and servers; PaaS lets you develop applications in a controlled environment; SaaS is pre-configured software that can be delivered via the Internet.
A cloud-based service can offer many benefits over an internal IT solution. These include faster deployment times, greater flexibility and better scalability. You may be able to get additional benefits depending on the provider, including automated backup/recovery and security compliance assurance.
