Well, I have to admit that it is a beautiful, sunny day here in Chicago.  I keep looking at the clouds and the sky…and speaking of which…. this has the been the main point of topic in our last two blogs.  Our last one reviewed the three main, core components of the Cloud, which include the following:

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

It is the last one, which is actually the most popular and the most widely used today by both corporate America and individuals of all kinds.  So, you may be scratching your head at this point, and asking, “What is so special about it?”  Well, this is where all of the software applications or downloadable you could ever hope reside.

But, before we delve deeper into the SaaS, let us illustrate the last fact with an example.  Suppose you are a freelance videographer and you need the best tools which are available to you.  One of the best ones that you can use in this regard is that of Adobe.

They have all sorts of great packages that you use.  But if you take a look at their website and peruse through some of them, they come at some jaw dropping prices which can break the budget of anybody.

But, Adobe has also come up with a different method.  You can purchase these products for a low monthly price, on a subscription based level.  In this regard, these applications are being stored and hosted in the SaaS, and are available on demand.

So, to answer your question, this is the greatest advantage of the SaaS:  Applications become very affordable to purchase to any business owner, because they are being hosted and maintained by contract with a trusted third party, namely the Internet Service Provider.

Another benefit of using SaaS based software applications is that they can be accessed very easily by any kind of Internet connection.  Therefore, you do not have to worry about installing any software and having your computer crash on you.  What makes the SaaS so great is that it utilizes what is known as a “Multitenant Architecture”.

This simply means that any single version of a software application (such as the Adobe Premier Pro-their leading video production software app) can be used by all people and entities that need to use it, or even just have an interest to try it out.

This is in part also why the costs of procuring software applications is so low on the SaaS-the cost is shared by all of the tenants who use it.

This kind of architecture also leads credence to the next major advantage of the SaaS:  Scalability.  Suppose for example you have tried the Adobe Premier Pro for your video needs and decide that it is not meant for you.  Well, you can scale this down, terminate your subscription, and try out some new type of video production software.

Or, if you are totally in love with the Premier Pro and decide you want to have a team of video editors who need to access it, you can also scale up and get different instances of it placed on different virtual servers so that your team can have full access to it as well.

So, think about all of this when you want to make your next software purchase – why go to the retail store???
