The advantages of using Cloud services are as below.

  • Pay when you use
  • No infrastructure cost
  • No IT Pros required

Could platform is very profitable for any short term projects and can build any high caliber infrastructure.

Major players in cloud services are:

SaaS applications run directly from a web browser without any downloads or installations required, with some need plugins. With SaaS, it’s easy for enterprises to streamline their maintenance and support, because vendors can manage everything. 

SaaS is nothing but same as the old thin-client model of software.

SaaS moves the task of managing software and its deployment to third-party services.

Customer Relationship Management software like Salesforce is one of a good example for SaaS applications. SaaS applications mostly subscription base model.

The purpose of the SaaS applications is to reduce the software cost by removing technical staff to manage to install to upgrade software.

SaaS offering types:

  • Healthcare-related applications
  • Customer relationship management
  • Email and collaboration

SaaS Examples:

  • Concur
  • Citrix GoToMeeting
  • Cisco WebEx
  • Google Apps
  • Salesforce
  • Workday

SaaS Use-Case: Replaces traditional on-device software


What developers gain with PaaS is a framework. The developer can build upon to develop or customize applications by acquiring with PaaS Framework. PaaS makes the development, testing, and deployment of applications quick, simple, and cost-effective.

Enterprise operations or another service providers manage OS, virtualization, servers, storage, networking, and the PaaS software itself. Developers just manage the applications.

Like we create macros in Excel, PaaS allows you to create applications using software components. Apprenda is one of the providers of a private cloud PaaS for .NET and Java for the needs of enterprises.

PaaS provides a platform on which software can be developed and deployed. PaaS is built on virtualization technology. PaaS can be added as scalability and demand grow instead investing in hardware with duplicated resources.


PaaS providers:

  • Google App Engine
  • Red Hat’s OpenShift
  • Heroku


Cloud infrastructure services, known as Infrastructure as a Service (IaaS), are self-service models for accessing, monitoring, and managing remote data center infrastructures.

Companies can purchase IaaS based on consumption, similar to electricity or other utility billing instead of having to buy hardware outright.IaaS providers have dashboard and API’s to control cloud servers and resources.IaaS clients can access to their servers and storage like traditional servers with the higher order of scalability.

Enterprises can outsource their IaaS and build a virtual data center in the cloud.The advantage is not to budget or to invest in capacity planning or the physical maintenance. IaaS clients have actual control over their infrastructure than users of PaaS or SaaS services. The primary uses of IaaS include the actual development and deployment of PaaS, SaaS, and web-scale applications. Many IaaS providers now offer databases, messaging queues, and other services above the virtualization layer as well. End users gain with IaaS is infrastructure on top of which they can install any required platform. Companies IT pros are responsible for updating these if new versions are released.


IaaS Examples:

  • Amazon Web Services (AWS)
  • Cisco Metapod
  • Microsoft Azure
  • Google Compute Engine (GCE)
  • Rackspace Open Cloud
  • IBM SmartCloud Enterprise.


IaaS Use-Case: Companies can extend current data center infrastructure for high peak seasons like increased Christmas holidays and Thanksgiving time. They don’t need to invest huge investment for infrastructure for a short period.




  • Save substantial capital costs with zero in-house server storage and application requirements.
  • Scale up or scale down quickly as your needs change.
  • Access data anytime, from anywhere: home or on the road, and increase mobility and productivity.
  • Avoid server upgrades, data backup, hardware replacement delays and risk of server crashes
  • Avail reliable and flexible backup/recovery solutions.
  • High security, privacy, and compliance.


The cloud is a very broad concept, and it covers just about every possible sort of online service when businesses refer to cloud procurement,


Cloud services are usually three models of cloud service under consideration like below:


  • Software as a Service (SaaS)
  • Platform as a Service (PaaS)
  • Infrastructure as a Service (IaaS)


The cloud is a very broad concept. It is important to understand the fundamental differences between the core categories of cloud services available.

We can see the high-level differences between SaaS, PaaS, and IaaS.
