As iPads, tablets, smartphones, and other mobile devices become more ubiquitous, so do the means of translating IBM i apps to mobile-friendly versions.

 

The convenience of mobile devices is just the beginning of yet another technology advance that one suspects will utterly transform business life over the next few years. Not that it hasn't already, but we most likely have only begun to exploit 24/7 connectivity compared to what will be commonplace in the future.

 

Unlike some technological innovations of the past, mobile access to information is being embraced by IBM i users just as much as by the mainstream public. No better illustration of this trend exists than the number of existing application-development and modernization tools that include the ability to extend i-server apps to mobile appliances.

Demand Outstripping Supply

"The demand from employees to use mobile applications for their work is huge," observes Sam Elias, vice president and general manager of Rocket Software's application development, integration, and modernization business unit. "There is a ten-to-one ratio of employees who need mobile-enabled applications to in-house development teams who can provide them. IT shops are trying to keep their heads above water because mobile applications have been adopted so quickly compared to any other development trend, and companies are looking for ways to develop and deploy applications quickly to their mobile workforce."

 

What's causing this outstripping of supply, however, may be the simple illusion that translating software from the green screen to the palm screen is more complicated than it really is.

 

"There are still a lot of people who don't understand that this [translation of apps] can be done fairly quickly and easily," notes Eamon Musallam, product manager at looksoftware. "The lack of infrastructure puts people off. There's a lack of knowledge about options," he adds.

 

"I think there are different sets of challenges here," observes Alex Roytman, CEO of Profound Logic Software. "For the business execs, the challenges include determining the business benefits of mobilizing, determining what devices to use, and determining what development costs are involved. For developers, the challenges are understanding and agreeing on the technologies (front- and back-end languages involved) for mobile-enabling and creating new mobile apps for IBM iespecially when native device features are being integrated into the applicationand whether or not they have the right tools/skill sets to take on mobile projects."

 

"So the current situation is that companies don't have a stable of mobile developers," summarizes Elias, "but they also don't want to pay someone else to develop mobile apps for their internal users. That's why there's a market for vendor tools geared toward in-house developers."

Creating New Apps vs. Translating Existing Ones

Is there more demand for creating new apps with the added capabilities of mobile gear or for translating existing server apps to mobile-device versions?

 

"The latter appears to be more common," Musallam comments. "Our customers and prospects are seeking ways of taking existing functionality in existing IBM i 5250 applications and making a subset of that functionality available in mobile devices. There are many variations on this, but that's a common starting point."

 

"Really, it depends on the business objective," disagrees Elias. "In general, our customers are responding to their employees' need to access key parts of IBM i applications via a mobile application user experience that's no different from what they expect from the other apps on their phones or tablets."

 

"We really see a range of different approaches, which includes both new development and mobile-enabling existing green-screen apps, with no clear winner," Roytman observes. "However, those that are mobile-enabling existing apps will often add new capabilities that you can’t get in a green-screen, such as maps, signature capture, and taking pictures with the device to associate with data entry."

 

The demand, it seems, also doesn't care much about what goes on under the covers to deliver mobile access to server apps.

 

"Your typical mobile user couldn't care less about whether the app they are using is native or hybrid or HTML5. They just want it to work on their mobile device, be intuitive to use, and give them the info they need quickly. So our customers create their mobile apps around that need," Elias stresses.

 

"Most customers are risk-averse at the moment, and so they are typically looking for solutions that are lower cost and lower risk," Musallam notes. "Taking existing applications and reusing the existing business logic for mobile devices generally achieves these objectives."

The Future Is More Demand

When asked which technology will most affect the future of mobile devices, Elias cites HTML5. "Companies are looking for the fastest way to get an app out to enterprise users on multiple mobile platforms, and the value proposition of HTML5 is that you can build that app one time and it will run on all common platforms."

 

Roytman agrees. "I think the next most critical technology is HTML5 and hybrid applications, which address the costs and development effort associated with creating apps for multiple mobile platforms. I believe most enterprise mobile apps going forward will be based on HTML5/hybrid technologies."

 

"I don't think there is one specific critical issue," opines Musallam. "It's more the continued rapid adoption of mobile devices among management and users within the IBM i community that makes it increasingly compelling and a higher priority as time progresses."

 

Whether your enterprise needs to build new mobile apps or to simply provide mobile access to existing server software, there are numerous application-building options available, most of which can deliver either option.
