Let’s start discussing about what are the services provided by cloud computing? So in terms of services cloudis mostly refer as XaaS means everything as a service, and this XaaS is categorised as:

  1. Software as a service (SAAS)
  2. Platform as a service (PAAS)
  3. Infrastructure as a service (IAAS)
Cloud computing services

1) Software as a service

Frequently refers as SaaS, it provisions the user or organizations to use the computing software or computer applications without even installing them on their system just with the help of Internet connection on the basis of their requirements. For using these services user only need to do a signup, and just start implementing your product or anything that is require.

Major advantage of this service is that it replaces the traditional configuration or installation of the software on the system.

SaaS Examples:

  • Google Apps,
  • Salesforce,
  • Citrix,
  • Cisco webEx,
  • Concur,
  • workday etc

2) Platform as a service

Frequently refers as PaaS, it provides a complete platform for a user or organisations including Operating System, databases, Programming languages execution environment and web servers etc. this model is frequently use by developers. And the best part about this service is if someone wants to develop some software or application which require high computation powered machine and high cost then those developers don’t have to spend much pennies on such machines, what they actually need to do is just switch to cloud computing and use those platforms and pay according to their requirements.

PaaS Examples:

  • Heroku,
  • force.com,
  • AWS Elastic
  • Beanstalk,
  • Microsoft Azure etc

3) Infrastructure as a service

Frequently refers as IaaS, this is a self service model, in this model the cloud service provider lets a user or organisation use their complete computing infrastructure including servers, storage and networking hardware as well as virtualised environment like hypervisor that is traditionally present on cloud service provider’s data centre.

IaaS Examples:

  • Amazon web service(AWS),
  • Amazon EC2,
  • Google Cloud Platform(GCP),
  • Microsoft Azure etc

Cloud computing has made technology like magic you can implement what you can think of.
