10.7 The Software Cloud: Why Buy When You Can Rent?

Learning Objectives

  1. Know how firms using SaaS products can dramatically lower several costs associated with their information systems.
  2. Know how SaaS vendors earn their money.
  3. Be able to list the benefits to users that accrue from using SaaS.
  4. Be able to list the benefits to vendors from deploying SaaS.

If open source isn’t enough of a threat to firms that sell packaged software, a new generation of products, collectively known as SaaS, claims that you can now get the bulk of your computing done through your Web browser. Don’t install software—let someone else run it for you and deliver the results over the Internet.

Software as a service (SaaS) refers to software that is made available by a third party online. You might also see the terms ASP (application service provider) or HSV (hosted software vendor) used to identify this type of offering, but those are now used less frequently. SaaS is potentially a very big deal. Firms using SaaS products can dramatically lower several costs associated with the care and feeding of their information systems, including software licenses, server hardware, system maintenance, and IT staff. Most SaaS firms earn money via a usage-based pricing model akin to a monthly subscription. Others offer free services that are supported by advertising, while others promote the sale of upgraded or premium versions for additional fees.

Make no mistake, SaaS is yet another direct assault on traditional software firms. The most iconic SaaS firm is, an enterprise customer relationship management (CRM) provider. This “un-software” company even sports a logo featuring the word “software” crossed out, Ghostbusters-style.J. Hempel, “Salesforce Hits Its Stride,” Fortune, March 2, 2009.

Other enterprise-focused SaaS firms compete directly with the biggest names in software. Some of these upstarts are even backed by leading enterprise software executives. Examples include NetSuite (funded in part by Oracle’s Larry Ellison—the guy’s all over this chapter), which offers a comprehensive SaaS ERP suite; Workday (launched by founders of Peoplesoft), which has SaaS offerings for managing human resources; and Aravo, which offers supply chain management software as SaaS. Several traditional software firms have countered start-ups by offering SaaS efforts of their own. IBM offers a SaaS version of its Cognos business intelligence products, Oracle offers CRM On Demand, and SAP’s Business ByDesign includes a full suite of enterprise SaaS offerings. Even Microsoft has gone SaaS, with a variety of Web-based services that include CRM, Web meeting tools, collaboration, e-mail, and calendaring.

SaaS is also taking on desktop applications. Intuit has online versions of its QuickBooks, TurboTax, and Quicken finance software. Adobe has an online version of Photoshop. Google and Zoho offer office suites that compete with desktop alternatives, prompting Microsoft’s own introduction of an online version of Office, with Oracle following as well. And if you use a service like Dropbox or you store photos on Flickr or Picasa, instead of your PC’s hard drive, then you’re using SaaS, too.

The Benefits of SaaS

Firms can potentially save big using SaaS. Organizations that adopt SaaS forgo the large upfront costs of buying and installing software packages. For large enterprises, the cost to license, install, and configure products like ERP and CRM systems can easily run into the hundreds of thousands or even millions of dollars. And these costs are rarely a one time fee. Additional costs like annual maintenance contracts have also been rising as rivals fail or get bought up. Less competition among traditional firms recently allowed Oracle and SAP to raise maintenance fees to as much as 20 percent.Sarah Lacy, “On-Demand Computing: A Brutal Slog,” BusinessWeek, July 18, 2008.

Firms that adopt SaaS don’t just save on software and hardware, either. There’s also the added cost for the IT staff needed to run these systems. Forrester Research estimates that SaaS can bring cost savings of 25 to 60 percent if all these costs are factored in.J. Quittner, “How SaaS Helps Cut Small Business Costs,” BusinessWeek, December 5, 2008.

There are also accounting and corporate finance implications for SaaS. Firms that adopt software as a service never actually buy a system’s software and hardware, so these systems become a variable operating expense. This flexibility helps mitigate the financial risks associated with making a large capital investment in information systems. For example, if a firm pays sixty-five dollars per month per user for its CRM software, it can reduce payments during a slow season with a smaller staff, or pay more during heavy months when a firm might employ temporary workers. At these rates, SaaS not only looks good to large firms, it makes very sophisticated technology available to smaller firms that otherwise wouldn’t be able to afford expensive systems, let alone the IT staff and hardware required to run them.

In addition to cost benefits, SaaS offerings also provide the advantage of being highly scalable. This feature is important because many organizations operate in environments prone to wide variance in usage. Some firms might expect systems to be particularly busy during tax time or the period around quarterly financial reporting deadlines, while others might have their heaviest system loads around a holiday season. A music label might see spikes when an artist drops a new album. Using conventional software, an organization would have to buy enough computing capacity to ensure that it could handle its heaviest anticipated workload. But sometimes these loads are difficult to predict, and if the difference between high workloads and average use is great, a lot of that expensive computer hardware will spend most of its time doing nothing. In SaaS, however, the vendor is responsible for ensuring that systems meet demand fluctuation. Vendors frequently sign a service level agreement (SLA)A negotiated agreement between the customer and the vendor. The SLA may specify the levels of availability, serviceability, performance, operation, or other commitment requirements. with their customers to ensure a guaranteed uptime and define their ability to meet demand spikes.

When looking at the benefits of SaaS, also consider the potential for higher quality and service levels. SaaS firms benefit from economies of scale that not only lower software and hardware costs, but also potentially boost quality. The volume of customers and diversity of their experiences means that an established SaaS vendor is most likely an expert in dealing with all sorts of critical computing issues. SaaS firms handle backups, instantly deploy upgrades and bug fixes, and deal with the continual burden of security maintenance—all costly tasks that must be performed regularly and with care, although each offers little strategic value to firms that perform these functions themselves in-house. The breadth of a SaaS vendor’s customer base typically pushes the firm to evaluate and address new technologies as they emerge, like quickly offering accessibility from mobile platforms like the BlackBerry and iPhone. And many contend that cloud computing can actually be greener. SaaS and other cloud firms often have data centers that are better designed to pool and efficiently manage computing resources, and they are often located in warehouse-style buildings designed for computers, not people. Contrast that with corporate data centers that may have wasteful excess capacity to account for service spikes and may be crammed inside inefficiently cooled downtown high-rises. For all but the savviest of IT shops, an established SaaS vendor can likely leverage its scale and experience to provide better, cheaper, more reliable standard information systems than individual companies typically can.

Software developers who choose to operate as SaaS providers also realize benefits. While a packaged software company like SAP must support multiple versions of its software to accommodate operating systems like Windows, Linux, and various flavors of Unix, an SaaS provider develops, tests, deploys, and supports just one version of the software executing on its own servers.

An argument might also be made that SaaS vendors are more attuned to customer needs. Since SaaS firms run a customer’s systems on their own hardware, they have a tighter feedback loop in understanding how products are used (and why they fail)—potentially accelerating their ability to enhance their offerings. And once made, enhancements or fixes are immediately available to customers the next time they log in.

SaaS applications also impact distribution costs and capacity. As much as 30 percent of the price of traditional desktop software is tied to the cost of distribution—pressing CD-ROMs, packaging them in boxes, and shipping them to retail outlets.M. Drummond, “The End of Software as We Know It,” Fortune, November 19, 2001. Going direct to consumers can cut out the middleman, so vendors can charge less or capture profits that they might otherwise share with a store or other distributor. Going direct also means that SaaS applications are available anywhere someone has an Internet connection, making them truly global applications. This feature has allowed many SaaS firms to address highly specialized markets (sometimes called vertical nichesSometimes referred to as vertical markets. Products and services designed to target a specific industry (e.g., pharmaceutical, legal, apparel retail).). For example, the Internet allows a company writing specialized legal software, for example, or a custom package for the pharmaceutical industry, to have a national deployment footprint from day one. Vendors of desktop applications that go SaaS benefit from this kind of distribution, too.

Finally, SaaS allows a vendor to counter the vexing and costly problem of software piracy. It’s just about impossible to make an executable, illegal copy of a subscription service that runs on a SaaS provider’s hardware.

Key Takeaways

  • SaaS firms may offer their clients several benefits including the following:

    • lower costs by eliminating or reducing software, hardware, maintenance, and staff expenses
    • financial risk mitigation since start-up costs are so low
    • potentially faster deployment times compared with installed packaged software or systems developed in-house
    • costs that are a variable operating expense rather than a large, fixed capital expense
    • scalable systems that make it easier for firms to ramp up during periods of unexpectedly high system use
    • higher quality and service levels through instantly available upgrades, vendor scale economies, and expertise gained across its entire client base
    • remote access and availability—most SaaS offerings are accessed through any Web browser, and often even by phone or other mobile device
  • Vendors of SaaS products benefit from the following:

    • limiting development to a single platform, instead of having to create versions for different operating systems
    • tighter feedback loop with clients, helping fuel innovation and responsiveness
    • ability to instantly deploy bug fixes and product enhancements to all users
    • lower distribution costs
    • accessibility to anyone with an Internet connection
    • greatly reduced risk of software piracy
  • SaaS (and the other forms of cloud computing) are also thought to be better for the environment, since cloud firms more efficiently pool resources and often host their technologies in warehouses designed for cooling and energy efficiency.
