What is Cloud Computing?

Achieve more, faster, with less resources

Cloud computing is the use of on-demand distant IT resources that are owned and operated by others. These apps and resources are used over the internet on a pay-for-use basis from any connected computer. It has fast, easy scalability and keeps data safe, even if your computer breaks.

Software as a service (SaaS)

SaaS are cloud-based applications that connect to users’ computers via the internet, usually via a web browser. With SaaS, you no longer have to purchase, install, update and maintain the software as this is all done on the cloud.

PaaS

Platform as a service (PaaS)

PaaS supports the complete life-cycle of building and delivering cloud (web-based) applications without the cost and complexity of buying and managing the underlying hardware, software, provisioning, and hosting.

IaaS

Infrastructure as a service (IaaS)

IaaS provides companies with servers, networking, storage, and data centre space on a pay-per-use basis, saving any investment in your own hardware. Flexible, innovative services are available on demand and can be scaled to need.

Public cloud

Public cloud

Public clouds are owned and operated by companies that offer rapid access over a public network. Users do not need to purchase hardware, software, or supporting infrastructure, which is owned and managed by providers. Public cloud provides SaaS and PaaS apps.

Private cloud

Private cloud

Designed for a company’s specific requirements and operated solely for a single organisation. It can be managed internally or by a third party, and hosted internally or externally. Private clouds provide more control of resources and additional security. Private cloud provides PaaS and IaaS apps.

Hybrid cloud

Hybrid cloud

Hybrid cloud uses a private cloud foundation combined with public cloud services, allowing companies to keep critical applications and sensitive data private whilst taking advantage of public cloud resources like SaaS and IaaS.
