SaaS – Software as a Service
In cloud computing, there are three different service models that are designed to cater specific requirements of the users. Let’s have a brief look at cloud service models.
SaaS – Software as a Service
SaaS is considered as the basic service model in cloud. The software applications that are only on the online market fall under the Software-as-a-Service category that is also known as known as SaaS.
The only example that can be best here is the email service.
If you've got an online provider, you will need a desktop or mobile application to access the email; else you will have to host it on your own servers. Not only would you be required to run an incoming email server, sometimes using the protocols like IMAP or POP would also work, however also along with this you will have to run an SMTP or outgoing email server. Once this is done, you will have to assemble your desktop or mobile email application to attach to those servers, add the levels of security required, the time for quota management, and many more.
For personal email, people usually prefer to choose from a range of free web-based email servers like Gmail, YahooMail, or Hotmail, instead of setting up an email account from their supplier server. Not only are the web-based emails free and supported with advertisements, however users are free to do any server maintenance if required in the future. Another example of SaaS would be the applications that are known to increase the productivity of the user and these applications can be easily found online.
All these applications run and instantly store their online knowledge, the users never have to worry about how to manage, save, and back up their important files. Of course, currently it would become your email server’s responsibility to make sure that your data is safe and secure. Some of the different samples of SaaS are the online games, Salesforce, and the IBM's NetSuite.
One of the easiest options to consider SaaS is be adopting it as software. But now the big question is, after download does one transfer and install it on your system, or will the users have to access it with the help of a mobile application or application? If the users consider the latter, without a doubt you will be working with SaaS cloud application. However, the users will never the management of the SaaS applications in their hands, the server will manage and handle all the requirements. There is no requirement to fix bugs within the code itself or make any further changes to that. This is often the responsibility of the seller. To some of the users, this lack of management is unacceptable.
