SaaS or software as a service is an innovative system of using software that has a remarkable advantage over the traditional use of software. In this system, the entire software is present in a web browser. You pay a subscription fee and can use this software.

In normal cases, you buy software with a lump sum and take out a license or ownership of it. Then you can use it for six months or a year. In this case, you will receive updates on the software only when the sales rep visits you in your office. Moreover, there is a time lag as you acquire the software and get it up and running.

Unlike this system, the SaaS enjoys several advantages. You can start using the software as soon as you pay the subscription. It is remotely accessed. So, there is no time lag. Moreover, the subscriptions are often paid monthly. So, if you do not like the services of a provider, you can change it next month. Updates are also pushed frequently so that you remain at the cutting edge.

As long as you are not working with intellectual property or other data of a sensitive nature, SaaS can be highly beneficial to you. These services are best suitable for platforms which use industry standard workflows. You can pay on monthly basis, though a few services are priced per transaction.

Some of the important elements of the SaaS architecture are as follows:

  • A user case model that portray a typical scenario. It showcases the back end data exchange.
  • A conceptual architecture. It gives a long term prediction with an overall view of the various SaaS elements which are required for its implementation.
  • Finally, reference architecture can greatly enhance the utility of the SaaS architecture. It often comes as a template architecture which can easily be applied to specific problems.

One of the best software as a service platform is provided by IBM. You can try their private cloud for the best SaaS. This is an application where you can actually customize the cloud computing. The best in-class technology and security standards that are the hallmark of IBM are used for these private cloud applications.

It includes such diverse and advanced elements like virtualized storage where workloads are consolidated into a single system, the system z cloud solution where you can build your customized solution for the platform of your choice. The PureApplication system is another proprietary system of IBM that forms one of the elements of public cloud infrastructure.
