For most companies, IT infrastructure is not a core business that brings in revenue but is used to support daily activities. For those companies it is most often the best business decision to fully outsource IT infrastructure bringing it down to operational expense, and focus on core business. Usually, cloud infrastructure is the best choice to fit all the customers needs.

Advantages of leased cloud infrastructure:

  • Transferring from a significant investment in hardware to a substantially reduced operating expense based approach.
  • More flexible cost adjustments to the services used, allowing for payment by usage instead of budgeting up to four years in advance.
  • Greater availability of services, at a lower cost of use.
  • Automated backup without the need for user intervention.
  • Centralized, simpler software upgrades.
  • A higher level of data security and traceability through existing certificates.






From the perspective of the service itself, cloud computing is based on three basic models:

  • IaaS (Infrastructure as a Service) - refers to hardware and software: servers, data storage, network equipment and operating systems – the client defines and configures virtual servers (resources, network, OS).
  • SaaS (Software as a Service) - refers to applications designed for the end user, optimized for working in the cloud and delivering over the web.
  • PaaS (Platform as a Service) - refers to a set of tools that enable the fast and efficient development and implementation of applications.


By definition, Altus IT Cloud is an IaaS, but PaaS and SaaS are commonly supplied in cooperation with partners.
