When Cloud Computing gained mainstream attention of the IT mavens, it started undergoing a lot of critical assessments. It was like a new kid around the block trying to make his way into the neighbourhood gang. And it still is so to a large extent.
Out of all three – SaaS (Software-as-a-Service), PaaS (Platform-as-a-Service) and IaaS (Infrastructure-as-a-Service), SaaS has been through criticism the most. It is so because SaaS has evolved faster and has gained adoption far more than PaaS and IaaS. SaaS has the characteristics such that it can be made available for every kind of software application — CRM (Customer Relation Management), Project Management, SDLC Management and even data storage.
There have been many talks and write-ups about busting the myths about SaaS, but it continues to find itself in the grip of new myths. Some of the myths that I’d like to talk about are listed below:
Myth #1: SaaS is less reliable and less secure
Security in general is a big concern with companies contemplating on implementing cloud computing. An enterprise cloud stack would contain many SaaS applications. These would be the interface for the origin of data which would need to be secured. Since the data is stored at the data centers that are not physically present on the user’s site, it is perceived as less secure. However, I’d like to point out here that this is just a myth that needs to be busted, as customized SLAs can be signed with the SaaS vendors to ensure vendor accountability in case of security breach, just the same way as it is done in IT outsourcing services. When did outsourcing industry stall because of sensitive data transfers? I am sure the IT folks from the outsourcing industry will have a lot to say here.
Myth #2: SaaS will fade away over time
Many even consider that SaaS will fade away over time; it is more of a hype. But that’s not true. SaaS has been around in a disrupting way for more than 10 years now. The fact that software for almost any domain can be provided as SaaS with added advantages, makes SaaS potentially pervasive. SaaS is going to be the de-facto way to utilize IT in the future.
Myth #3: SaaS applications cannot be customized and have feature limitations
That is again a very restricted outlook. SaaS applications usually develop and evolve on a monthly or quarterly basis, thereby making its functionality (or the usability) more sophisticated over time. The SaaS applications come with APIs that you can build on.
Customization is seen as a problem when the requirement is so specific that it is not being addressed by the solutions available in the market. The answer in this case is either to buy traditional on-premise version and spend heavily on customization, or go for in-house development. Well then, that means you have the budget for developing software that meets your specific needs and you definitely cannot live without your set of rules. If this is the case, then you can certainly look into SaaS products and build on the API provided by the vendor, that will help you integrate the SaaS application with the rest of your enterprise IT stack.
Myth #4: SaaS will take away the control
This is another myth. Yes, when the control is suddenly taken away from you, it leaves you unsettled. But in some cases it is only a psychological barrier that acts against adopting the change. Here when we say that the data resides in someone else’s data center, it feels jittery. But the SLAs of the SaaS vendors talk about security aspects which clearly show how the data will be secured and backed-up. (In fact, this must be one of the things in your due diligence list while selecting a SaaS vendor). It is not at all advisable to own the entire IT system if you are not an IT company. The advantages achieved by doing away with the management of the entire IT department are much higher than dwelling with the myth that SaaS takes away the control.
Myth #5: SaaS is expensive in the long run
Cost is a genuine concern but again, it is a myth that SaaS turns out to be expensive in the long run. While doing a cost-benefit analysis you must consider all factors that contribute towards the cost – the manpower requirement for maintaining servers, upgrades, encryption and data back-up, and not just the cost of buying user space under SaaS vs. user license under traditional method. If you calculate the total cost that you save per month when you include all the factors, you will see that SaaS will actually be inexpensive in the long-run also.
Have you come across any such perceptions about SaaS that can be categorized more as a myth than a reality? Please share it with us.
