Is SaaS Too Good to Be True?

When it comes to newish technologies, it's often difficult to separate truth from exaggeration. On one side you have vendors and their marketing materials telling prospects that whatever they're selling has the ability to completely transform their business. It'll save them money, turn their employees into lean, mean efficiency machines and leave competitors gasping in the dust. On the other side you have the vendors whose products the newish technology could supplant and a whole bunch of skeptical analysts warning folks not to rush into anything without lots and lots of evaluation.

 

While this tension usually ends up being a good thing for technology buyers, there can be some painful missteps along the way. When backlash kicks in, it sometimes gets ugly. We've seen it with virtualization and service-oriented architecture, among others.

 

It's especially true of Tools for Understanding SaaS, which seems so compellingly different from traditional on-premise software. No convoluted licensing terms here, say SaaS vendors. Just pay a monthly fee for the number of folks using the software. Lengthy implementations? A thing of the past with SaaS, say the vendors, who promise their systems can be up and running in weeks, not months or (gasp) years. And hey, I hope you've got some stuff you want to spend capital on, because you sure won't be spending it on software. All of these points seem especially compelling in light of the awful economy.

 

Yet, at the same time, there are those niggling voices saying, "If it's too good to be true..." (Oh right, it's those darned analysts.) What about security? Do you trust a third party to take good care of your data? What if you need to customize an application or integrate it with other apps? Is SaaS really as cost-effective as it seems? And who are all these guys selling SaaS? Will they even be around in a few years?

 

To be fair, analysts aren't the only ones raising these kinds of questions. They are definitely worth considering. Many CIOs are, judging by a McKinsey & Co. survey that found tech execs were especially influenced by integration and deployment speeds when evaluating SaaS.

 

Jeff Kaplan, managing director of THINKstrategies, a consulting company specializing in SaaS, cautioned potential SaaS users to exercise care when I interviewed him a few years ago. Though the interview is nearly two years old, his advice is still some of the best I've heard. He said:

 

Users have to do a thorough job of investigating what is available so they can set the right expectations for themselves. The concept of on-demand is a relative term. There are many SaaS solutions that you can point, click, procure and use instantaneously. But there are many others that refer to themselves as on-demand which really do demand a certain amount of time and effort to deploy. They do still require some customization, some integration with existing applications, or they may require migration of data that might entail time and effort not only on your own part, but you may even need a consultant or integrator to help you. The other term that is a relative term is pay-as-you-go. Many of the services are genuinely pay-as-you-go, while others will require a certain amount of upfront commitment. Some require a first-year commitment. So that kind of thing has to be carefully evaluated. [SaaS will] still be more flexible than the traditional approach, but they may not be as on-demand or as easy to pay for as you think.

 

Noting that there has been "a great deal of hype around SaaS," Gartner analyst Robert DeSisto addresses five "myths" about it in an ITPro item. They are:

 

1. Does SaaS cost less than traditional on-premise software? Probably not, says Gartner. As with other arrangements that involve leasing a product or service, users save up front but tend to pay more over the long haul. Not everyone agrees with this, however. "I always wonder what happened to their calculators," said Ingres CIO Doug Harr when I asked him about such cost contentions during a recent interview about his company's use of SaaS. He told me the upfront fee for the on-premise software he purchased for his pre-Ingres employer was more expensive than seven years' worth of a similar number of monthly seats for Salesforce. The financial advantage becomes even more pronounced when the costs of software maintenance, upgrades and the personnel required to run it are included.

 

2. Is SaaS faster to deploy than on-premise software? Yes and no, says Gartner. While SaaS is certainly simpler and quicker for simple systems, it tends to become more complex if customization is required. While a vendor may promise it can get a SaaS system up and running in a month, it may end up taking more like seven months. I'm sure this is true, but the industry has yet to see (or at least to report) a SaaS implementation so complex it results in a company suing a vendor for a whopping $100 million, as happened earlier this year with a failed ERP project.

 

3. Is SaaS the same thing as utility computing? (That is, pay as you go.) Nope, says Gartner. Organizations almost always pay a set amount for SaaS applications, no matter how much they actually use them. As Kaplan suggested, it's important to determine how SaaS vendors charge for use before making any commitments.

 

4. Is it tough to integrate SaaS with other applications? Not so much, says Gartner, noting that batch synchronization, real-time Web services and even mashups may make integration issues less of a deal-breaker than some may think. At least one CIO found SaaS integration wasn't that big of a deal, wrote IT Business Edge blogger Loraine Lawson last spring. A growing number of vendors such as Cast Iron offer tools that promise to simplify SaaS integration.

 

5. Is SaaS just for basic systems? Not anymore, says Gartner. Platform-as-a-service facilitates SaaS customization. Saugatuck Technology VPs Michael West and Mark Koenig told me much the same thing when I interviewed them last spring. They said that platforms such as Salesforce's Force.com will make it easier not only for developers to create custom SaaS applications but also to migrate existing on-premise applications to SaaS.
