Modern mobile technology may have been born with the first iPhone, a quintessential consumer device, but it wasn't long before the business possibilities began to emerge. Fast forward to today, and it's difficult to find a company that hasn't embraced phones and tablets for its employees to some degree.
It's not difficult to see why. After all, the potential is nothing if not compelling: an untethered workforce equipped with easy-to-use tools for workers to be productive no matter where they are and at any time of day.
That allure, indeed, is surely part of the reason IT organizations will dedicate at least 25 percent of their software budgets to mobile application development, deployment and management by 2017, according to IDC. By that same year, in fact, the vast majority of line-of-business apps will be built for mobile-first consumption, IDC predicts -- and for competitive necessity at least as often as for efficiency or productivity.
The "bring your own device" trend -- in which employees bring their own devices into the workplace -- is one key factor contributing to this massive shift in enterprise computing. It's an extension of the consumerisation trend seen in enterprise technology more broadly: People want to have the same mobile tools at work that they've become accustomed to in their personal lives.
"This is a revolution," said Eldad Eilam, CEO of mobile productivity vendor HopTo. "Everyone is looking into BYOD."
A veritable "tsunami of devices" has entered companies as a result, said Rana Kanaan, vice president of products at workspace-as-a-service provider Workspot. Also playing a role, however, is what Kanaan calls "the rise of the corporate citizen": independent-minded employees who place a high value on the ability to work wherever and whenever they want.
Put those two trends together, and IT is left with a very different landscape than what it faced years ago.
"Originally, we all worked on desktop computers in the office," Kanaan said. "Then, in the first generation of the mobile enterprise, we started working from somewhere else, but still on computers; we tried to solve that through desktop virtualisation."
When mobile technology first began to enter the corporate world, employers tried to limit it to specific, locked-down devices and applications. But users rejected that.
"The problem is, computing happens everywhere," Kanaan said. "That kind of control doesn't work -- it made users revolt."
Today's workers simply expect to be able to use the technologies they want and to be able to use them any time, said Michael Luu, IS director for the city of Milpitas, California, which uses Workspot's technology for mobile access. "The expectation is that even if you're on vacation, you respond to email," he said. "It's just part of normalcy now."
Vendors of enterprise software are racing to address these new expectations in numerous ways. With its workspace-as-a-service offering, for example, Workspot lets users securely access apps and data from any device, it says.
Enterprise-software heavyweight Salesforce has committed to a "mobile first" philosophy with its own applications, said Anna Rosenman, senior director of product marketing for the Salesforce Analytics Cloud.
"If you look at the consumer space, people spend at least 50 percent of their time on mobile devices," Rosenman said. "We're seeing our users closely mirroring that behaviour."
Even Facebook is working on an offering focused on the mobile enterprise: Facebook at Work, which is now in beta.
"The cornerstone of the experience is mobile," said Elisabeth Diana, Facebook's director of corporate communications. "It's a similar look and feel to Facebook; the primary difference is that information shared through Facebook at Work stays within the company."
A handful of companies are currently testing out the technology, and Facebook hopes to expand that number soon, Diana said.
HopTo focuses on enabling mobility while allowing companies to leverage their existing Windows-based infrastructure, including Windows Remote Desktop Services, Active Directory, SharePoint sites and cloud storage services.
"The challenge we're seeing is that many companies have a massive amount of legacy software that's used to run the business," Eilam said. "Converting that for mobile is extremely challenging."
Indeed, even as new solutions continue to emerge, there is no shortage of challenges remaining for today's newly mobile organizations -- and the vendors that serve them.
Security, for example, remains a big one: By the end of this year, only 15 percent of large companies will have adequate mobile security governance, according to IDC.
"Mobile devices tend to store things locally," Eilam said. "That creates a really serious challenge: document sprawl." HopTo's answer to that problem is to keep storage at the back end, he said. Files can be edited remotely but are saved back to the place in which they were opened, such as SharePoint or cloud storage.
Workspot's Kanaan points to a need for what she calls contextual security. The idea is to build security technology that can recognize when a user is trying to get to sensitive data on a mobile device and respond by requiring extra authentication.
"That's a huge industry challenge for us to figure out, especially when you look at regulated industries like health care and finance," she said.
There's also a need for common ground on mobile app development, Kanaan said. "It's slow and costly to make enterprise apps work on mobile," she said. "We don't have standardization there, and enterprises are still struggling with that."
In short, there's no doubt the process of mobilizing the enterprise world is happening quickly, but there's still plenty to be addressed. Said HopTo's Eilam, "I think we'll continue to see a mix of legacy and mobile technologies for a couple of decades still.
