SSaaS(Software as a Service ):

Software as a service (SaaS) is a software distribution model in which a third-party provide hosts applications and makes them available to customers over the Internet. SaaS is one of SaaS removes the need for organizations to install and run applications on their own computers or in their own data centers.

This eliminates the expense of hardware acquisition, provisioning and maintenance, as well as software licensing, installation and support. Other benefits of the SaaS model include:

PaaS(Platform as a Service ):

Platform as a service (PaaS) is a concept that describes a computing platform that is rented or delivered as an integrated solution, solution stack or service through an Internet connection

. The solution stack may be a set of components or software subsystems used to develop a fully functional product or service, such as a web application that uses an OS, web server, database and programming language. More generically, the solution stack may deliver an OS, middleware, database or application.

IaaS(Infrastructure as a Service ):

Infrastructure as a service (IaaS) is a form of cloud computing that provides virtualized computing resources over the internet. IaaS is one of the three main categories of cloud computing services, alongside software as a service (SaaS) and platform as a service (PaaS).

Infrastructure as a Service (IaaS): hardware is provided by an external provider and managed for you

Platform as a Service (PaaS): in addition to hardware, your operating system layer is managed for you

Software as a Service (SaaS): further to the above, an application layer is provided and managed for you - you won't see or have to worry about the first two layers

DaaS(Desktop as a Service ):

Desktop as a service (DaaS) is a cloud computing offering in which a third party hosts the back end of a virtual desktop infrastructure (VDI) deployment. Desktop as a service (DaaS) is a cloud computing solution in which virtual desktop infrastructure is outsourced to a third-party provider.

DaaS functionality relies on the virtual desktop, which is a user-controlled session or dedicated machine that transforms on-demand cloud services for users and organizations around the world. This is an efficient model in which the service provider manages all the back-end responsibilities that would normally be provided by application software.

MaaS(Monitoring as a Service ):

IT infrastructure monitoring should an essential part of the IT Management Policy for an organization that is reliant on IT infrastructure. Proactive monitoring provides business continuity, quicker disaster recovery and easier capacity planning for all mission critical applications.

Monitoring as a Service (MaaS) in the Cloud is a concept that combines the benefits of cloud computing technology and traditional on-premise IT infrastructure monitoring solutions. MaaS is a new delivery model that is suited for organizations looking to adopt a monitoring framework quickly with minimal investments.

CaaS(Communications as a Service ):

Communications as a Service (CaaS) is an outsourced enterprise communications solution that can be leased from a single vendor. Such communications can include voice over IP (VoIP or Internet telephony), instant messaging (IM), collaboration and videoconference applications using fixed and mobile devices. CaaS has evolved along the same lines as Software as a Service (SaaS).

The CaaS vendor is responsible for all hardware and software management and offers guaranteed Quality of Service (QoS). CaaS allows businesses to selectively deploy communications devices and modes on a pay-as-you-go, as-needed basis. This approach eliminates the large capital investment and ongoing overhead for a system whose capacity may often exceed or fall short of current demand.
