For Web Apps, Get a Service Guarantee
As software-as-a-service (SAAS) adoption rises in the workplace, business managers mustn't overlook a key issue when selecting a Web-hosted applications suite: a service-level agreement.
Such contractual agreements, known as SLAs, bind the SAAS provider to meet specified levels of service. An SLA can address various
In other words, a business manager must make sure that a selected SAAS vendor can provide the level of reliable service the company needs. "IT [and business] managers need to understand the consequences for their operations if there's a problem. [They should] determine what downtime they can tolerate and compare that with what the vendor is offering," says Eric Maiwald, a Burton Group analyst.
Once a contract is signed and the hosted applications are implemented and woven into a company's workflow, migrating away to another provider will be costly and time-consuming.
Few Agreements Available
Unfortunately, SLAs are far from prevalent among SAAS vendors--and when offered, the standard agreements typically are thin and limited. That goes for large and small vendors alike. "For the most part, SLAs haven't been in place for the broad cross-section of SAAS [offerings] currently available," says Jeff Kaplan, a ThinkStrategies analyst.
For example, the Google Apps Premier Edition suite contains an availability guarantee only for its Gmail portion (for 99.9 percent uptime) and offers no commitment for the other components, which include word processing, spreadsheet, and presentation software.
"It would be comforting to have an SLA that covered the entire suite," says Mark Harrison, founding partner of Abraham Harrison LLC, provider of online marketing services.
Abraham Harrison, founded in 2007, has been using Google Apps Premier Edition for about one year, and the uptime of its hosted applications and services, though not 100 percent, has been excellent, according to Harrison. Downtime incidents have been rare and brief, and have never proven disruptive to the company's operations, he says. "We've never been crippled by an outage," Harrison says.
Still, should a significant Google Apps outage occur, it certainly would impact the company,
Harrison would also like to see Google Apps provide an offline component that would allow users to work on their local PCs when disconnected from the Internet, a capability he knows
That Harrison would feel more at ease with an SLA is telling. His company isn't an ordinary Google Apps customer. Although the relationship between Google and Abraham Harrison is purely of the vendor-client type, meaning that the company receives no compensation from Google, the Google Apps team has singled it out as a model small business whose feedback it regularly seeks. As a result, Harrison is in close contact with the Google Apps team.
What should a business manager look for in a service level agreement? The most basic item should be an uptime commitment for application availability, ideally 99.9 percent of the time or above. It should also address planned maintenance downtime, which, if too frequent, can become bigger burdens on customers than accidental outages.
When negotiating, inquire whether the SAAS vendor owns its own data centers or whether it depends on a partner, and be sure to investigate who the partner is and the extent of its infrastructure. Also verify that the SAAS vendor has key certifications, such as the SAS 70 Type II audit.
The SLA should address performance, as well, because
Kaplan recommends assuming the worst--that the vendor may go out of business altogether. To protect against that eventuality, customers can request that the vendor bring in a third-party "escrow" provider that will, for example, house the applications source code and data, in case the SAAS vendor goes under.
Business managers need to remember, too, that they must be proactive in securing a satisfying SLA, because SAAS vendors are understandably reluctant to volunteer generous service guarantees. Many elements outside of a SAAS vendor's control can interfere with the performance of its applications and with the integrity of data. Such external factors can include interference from security software on users' PCs, problems with the customer's local network, ISP issues, and structural Internet hiccups.
"Every provider will write an SLA, especially if you ask them, but it's going to cover things that they can control," Burton Group's Maiwald says.
Still, industry experts agree that, little by little, both buyers and SAAS vendors are recognizing the importance of SLAs, so business managers should find securing them progressively easier.
Enterprises Leading the Way
Help is coming indirectly by way of large enterprises, which initially limited their SAAS deployments to small groups and individual departments but are now extending their rollouts, sometimes companywide, says Forrester analyst Liz Herbert.
As a result, though business managers with little software-purchasing experience often used to be the only people negotiating with SAAS vendors, now IT and corporate procurement departments are getting involved and extracting more service guarantees from vendors, she says.
As vendors--such as Google, with its Apps Premier--set their sights on the enterprise market, they are hearing the message that feeble SLAs won't cut it there, says Eric Berridge, cofounder of Bluewolf, which provides consulting services to large companies adopting hosted applications.
"Google is probably 12 to 24 months away from being considered an enterprise play with Apps. They need to work on the SLA piece," Berridge says, adding that the suite's SLA must be extended beyond Gmail for enterprise acceptance. Bluewolf, a Google partner, is certified on Apps Premier deployments and is itself a satisfied user of the suite, whose uptime it considers solid. It also does consulting for customers of Salesforce.com and other SAAS vendors.
SAAS applications have so far been used for important processes--including office productivity, e-mail, customer relationship management, project management, and human resources operations--but they're not as common in industrial-strength operations in which downtime is outright deadly, such as back-end stock-trading systems and real-time point-of-sales transactions. When SAAS gains more traction in that critical application area, robust SLAs will follow. "When we get to that point in the SAAS market, you'll see a whole new type of SLA emerge," Berridge says.
Those and other factors will move the SAAS market toward stronger SLAs. "It's going to be an evolutionary process, driven a lot by customer demand, competitive pressures, and the specific nature of applications and their target audience," ThinkStrategies' Kaplan says.
Already, some SAAS vendors are adopting aggressive SLA postures. Mailtrust, which provides hosted e-mail primarily for small businesses, offers a 100 percent uptime guarantee. "We want to make it known to our customers that downtime is just not acceptable," says CEO Pat Matthews.
Mailtrust, which is backed by parent company Rackspace, a managed hosting specialist, also doesn't lock customers into long-term contracts, but rather renews the engagements on a monthly basis. Thus, dissatisfied customers can walk at any time, with no penalties.
In addition, Mailtrust has invested in troubleshooting and diagnostic tools so that it can help customers identify problems, even if they aren't on Mailtrust's end, something that Matthews says customers appreciate. "We embrace that [troubleshooting] part of our business, and we work really hard to make sure we don't get in the habit of blaming customers or third parties," he says. Mailtrust's uptime stands at 99.997 percent, according to RealMetrics.com.
Meanwhile, OpSource, which provides services to software makers of all sizes that want to deliver their applications over the Internet as SAAS, also offers 100 percent uptime for its servers and for the availability and performance of its customers' applications in its OpSource OnDemand service, says Chief Marketing Officer Richard Dym. "We made the decision that it made sense not to fool around," says Dym, whose company's clients include BMC and Business Objects.
Dym also sees a broader shift in the SAAS market toward stronger SLAs. "With SAAS, the SLA concept is now making inroads into the delivery of software over the Web," he says.
