Before only cloud computing technology was there and various cloud service providers were providing various cloud services to the customers. But now a new concept has emerged i.e Everything as a Service (XaaS) means anything can now be a service with the help of cloud computing and remote accessing. Where cloud computing technologies provide different kinds of services over the web networks.

With XaaS, business is simplified as they have to pay for what they need. This Everything as a Service is also known as Anything as a Service.

Examples of XaaS :
As XaaS stands for “Everything as a service”, There are many examples. There are many varieties of cloud computing models like –

  4. Infrastructure as a service (IaaS)
  5. Communication as a Service (CaaS)
  6. Network as a Service (NaaS)
    Database as a Service (DBaaS)
  7. Desktop as a Service (DaaS) etc.

IaaS also provide services to Azure and Google Computer Engine.

Everything as a Service Model Examples :

  1. Hardware as a Service (HaaS) –
    Managed Service Providers (MSP) provide and install some hardware on the customer’s site on demand. The customer uses the hardware according to service level agreements.
