“People were doing business with one another through the Internet already, through bulletin boards. But on the Web, we could make it interactive, we could create an auction, we could create a real marketplace. And that’s really what triggered my imagination if you will, and that’s what I did.”

-Pierre Omidyar, Founder of eBay.


Advantages of SaaS cloud computing

Scalable usage

In SaaS cloud computing the functionalities are scalable so you can measure your usage and pay accordingly. SaaS cloud computing offers vertical scalability, which means the customers have the option to access more services, fewer services, or on-demand tools.


Rather than buying new software customers can opt for auto software updates and security patches. This leads to a cost reduction in hiring IT staff.


As the service is on the cloud you can have access to the service around the globe regardless of location or time. Only availability of internet is a must thing. Due to this feature companies also outsource their SaaS offerings.

Flexible payments

Instead of buying software and hardware tools physically the customer just has to login into his SaaS software. The pricing of this model is charged according to services used so there is flexibility in payment. The service charges can be paid in advance also. If you are paying in advance then there exists a contract among the parties. 48% of the companies have an average contract of one year for the SaaS offerings. 14% of the companies have month-to-month contracts on SaaS offerings.

How does SaaS work?

SaaS is delivered through the internet. A software provider will host the servers at his data center or hire an ISV to provide services like data servers, networking, and computing. SaaS offerings run on the multi-tenant model which means that the single instance will be running on the SaaS host and that the single instance will be accessible to multiple tenants. There will be a number of tenants using one infrastructure and their data will be segregated.

This derives that the host has control over the maintenance, updating, bug fixes, this runs the system faster and easier. Rather than having to implement changes in multiple instances, engineers can make necessary changes for all customers by maintaining only one-sided instances.

Further, this also allows the tenant to choose from a pool of services without compromising speed, privacy, and security.
