Rise of Apple iPhone WebKit Advances Mobile Web's Role

HTML 5, Android, WebKit and advances in scripting and open source tools are allowing developers to target mobile devices better

Bringing enterprise applications effectively out to mobile devices has required some harsh trade-offs for developers. To gain access to devices, you lose functionality and portability, for example.

But thanks to the sizable impact that the Apple iPhone and its WebKit browser have had in the market -- and the lure of new business opportunities around mobile application stores -- the mobile Web has suddenly become more attractive and attainable for mainstream developers.

Such technologies as HTML 5, Android, WebKit and advances in scripting and open source tools are allowing developers to target mobile devices better than ever.

To learn more about how the development field for mobile Web applications is shaping up and how targeting the modern mobile Web browser may be removing some of the harshness from the trade-offs of the past, I recently assembled a panel of development experts.

Join me and Stephen O'Grady, founder and analyst at RedMonk; Wayne Parrott, vice president for product development at Genuitec, and David Beers, a senior wireless developer at MapQuest as we unpack the mobile Web.

Here are some excerpts:

O'Grady: For the first time, users have a real Web experience, as opposed to a stripped-down, bare-bones site in terms of what they can experience via the mobile Web. We need to pair the environmental and contextual factors with the advances that we've seen in the devices themselves. They've all come together to give us a rich and deep experience that will allow us to do things that we haven't been able to do before with the devices.

... When you're an enterprise vendor or a consumer vendor looking to target a volume audience, the fact is that there are a lot more mobile devices than there are desktops and laptops. There are mobile devices all over the planet. ... A lot of folks who might have traveled in the past and had applications like Siebel built into their laptops are now very often using those in a handheld or, in some cases, a netbook. So, economics, in terms of the application price and the volume audience that can be targeted is a big factor.

Gardner: How does an organization like MapQuest handle this whole issue of so many choices on that endpoint?

Beers: It's both a problem and an opportunity. From a developer's standpoint, and I am a developer, it's obviously difficult, because the amount of energy that you put in is divided across all of these different platforms. You have to make difficult decisions about developing the features you want ... and perhaps limiting the [device] targets that you're able to reach.

... On the positive side, fragmentation is a pejorative term that we use for differentiation. It's painful for developers, but we can't pretend that it's all a bad thing, because it's really driven by rapid innovation. A lot of the fragmentation that we see out there is because we've got these capabilities now on handsets.

Parrott: ... Both higher-end horsepower on the smartphones and a much better browsing experience or engine are now showing up on the iPhone-class machines. The programming model that is now available enables a whole new class of Web-type applications, which, in the past, has been reserved for native applications.

... As you start to move forward with the WebKit-type browsers now more prevalent on these smarter phones, it's starting to represent a more common platform that we have a choice to target our application functionality toward.

Beers: Mobile has been something that's been part of MapQuest right along. It comes in the nature of our business, which is getting people from A to B. So, it's intrinsically mobile oriented.

A lot of what we've been doing in the last couple of years has been developing what we've been calling native applications here. ... As to the question of HTML 5 and how this changes the picture for companies like MapQuest, we're beginning to see that these capabilities make it so that we can take technology that powers the mapquest.com website that people use on their desktop and repurpose that very quickly to provide a beautiful and powerful Ajax Web experience on modern smartphones.

We found that, considering the amount of development and energy that's gone into making our native applications, and has gone into the mobile website that we have out there right now, what it took to get a great application on the iPhone was minimal. It was very impressive.

... It's not just a mobile Web story. We see companies like Palm coming out with essentially native application environments that use those tools for the presentation layer. That brings up all kinds of very interesting and productive new models for releasing essentially a native application that has really rich access to the underlying features on the device -- things like GPS and the accelerometer. That's also a very exciting application model for companies like MapQuest to look at.

... You're starting to see phones that essentially will have two tiers on them. You're going to see developers having a choice to say, "Do I want to be operating completely in JavaScript and exercise my skills there in the WebKit environment, or do I want to have some of the application logic below that, perhaps in a Java environment, where it's essentially being a local server on the device for the presentation layer on top?"

You start to combine those things, and it allows all kinds of different components that are out there and that have been driving the innovation in the Internet to come into play on mobiles in ways that we haven't seen before.

Parrott: Obviously, one of the forces driving us has been enterprise organizations that want to move to the mobile Web. ... What they're pushing us for is, "How do we get there from here?" They already have a lot of their own infrastructure and resources in place, but moving that to the mobile Web has been a challenge for them.

[Now ] you have what we call the Mobile Web Programming Model so that you can now build some very sophisticated functionality that you run directly in the browser. You have to be educated about what you want to run local. Do you want to serve static content or do you want to push functionalities directly to the particular smartphone device?

We're servicing both -- helping educate and provide tooling and educational services for both Web developers and traditional enterprise developers -- Java developers who are moving over, bringing their programming know-how and experience, and applying that to dynamic Web applications.

@ThingsExpo Stories
The 3rd International Internet of @ThingsExpo, co-located with the 16th International Cloud Expo - to be held June 9-11, 2015, at the Javits Center in New York City, NY - announces that its Call for Papers is now open. The Internet of Things (IoT) is the biggest idea since the creation of the Worldwide Web more than 20 years ago.
Cultural, regulatory, environmental, political and economic (CREPE) conditions over the past decade are creating cross-industry solution spaces that require processes and technologies from both the Internet of Things (IoT), and Data Management and Analytics (DMA). These solution spaces are evolving into Sensor Analytics Ecosystems (SAE) that represent significant new opportunities for organizations of all types. Public Utilities throughout the world, providing electricity, natural gas and water, are pursuing SmartGrid initiatives that represent one of the more mature examples of SAE. We have s...
The security devil is always in the details of the attack: the ones you've endured, the ones you prepare yourself to fend off, and the ones that, you fear, will catch you completely unaware and defenseless. The Internet of Things (IoT) is nothing if not an endless proliferation of details. It's the vision of a world in which continuous Internet connectivity and addressability is embedded into a growing range of human artifacts, into the natural world, and even into our smartphones, appliances, and physical persons. In the IoT vision, every new "thing" - sensor, actuator, data source, data con...
The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example t...
How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happens, where data lives and where the interface lies. For instance, it's a mix of architectural styles ...
An entirely new security model is needed for the Internet of Things, or is it? Can we save some old and tested controls for this new and different environment? In his session at @ThingsExpo, New York's at the Javits Center, Davi Ottenheimer, EMC Senior Director of Trust, reviewed hands-on lessons with IoT devices and reveal a new risk balance you might not expect. Davi Ottenheimer, EMC Senior Director of Trust, has more than nineteen years' experience managing global security operations and assessments, including a decade of leading incident response and digital forensics. He is co-author of t...
The Internet of Things will greatly expand the opportunities for data collection and new business models driven off of that data. In her session at @ThingsExpo, Esmeralda Swartz, CMO of MetraTech, discussed how for this to be effective you not only need to have infrastructure and operational models capable of utilizing this new phenomenon, but increasingly service providers will need to convince a skeptical public to participate. Get ready to show them the money!
The Internet of Things will put IT to its ultimate test by creating infinite new opportunities to digitize products and services, generate and analyze new data to improve customer satisfaction, and discover new ways to gain a competitive advantage across nearly every industry. In order to help corporate business units to capitalize on the rapidly evolving IoT opportunities, IT must stand up to a new set of challenges. In his session at @ThingsExpo, Jeff Kaplan, Managing Director of THINKstrategies, will examine why IT must finally fulfill its role in support of its SBUs or face a new round of...
One of the biggest challenges when developing connected devices is identifying user value and delivering it through successful user experiences. In his session at Internet of @ThingsExpo, Mike Kuniavsky, Principal Scientist, Innovation Services at PARC, described an IoT-specific approach to user experience design that combines approaches from interaction design, industrial design and service design to create experiences that go beyond simple connected gadgets to create lasting, multi-device experiences grounded in people's real needs and desires.
Enthusiasm for the Internet of Things has reached an all-time high. In 2013 alone, venture capitalists spent more than $1 billion dollars investing in the IoT space. With "smart" appliances and devices, IoT covers wearable smart devices, cloud services to hardware companies. Nest, a Google company, detects temperatures inside homes and automatically adjusts it by tracking its user's habit. These technologies are quickly developing and with it come challenges such as bridging infrastructure gaps, abiding by privacy concerns and making the concept a reality. These challenges can't be addressed w...
The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. According to a recent IDG Research Services Survey this rate of traffic will only grow. What's driving t...
Connected devices and the Internet of Things are getting significant momentum in 2014. In his session at Internet of @ThingsExpo, Jim Hunter, Chief Scientist & Technology Evangelist at Greenwave Systems, examined three key elements that together will drive mass adoption of the IoT before the end of 2015. The first element is the recent advent of robust open source protocols (like AllJoyn and WebRTC) that facilitate M2M communication. The second is broad availability of flexible, cost-effective storage designed to handle the massive surge in back-end data in a world where timely analytics is e...
Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.
We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...
"Matrix is an ambitious open standard and implementation that's set up to break down the fragmentation problems that exist in IP messaging and VoIP communication," explained John Woolf, Technical Evangelist at Matrix, in this SYS-CON.tv interview at @ThingsExpo, held Nov 4–6, 2014, at the Santa Clara Convention Center in Santa Clara, CA.
P2P RTC will impact the landscape of communications, shifting from traditional telephony style communications models to OTT (Over-The-Top) cloud assisted & PaaS (Platform as a Service) communication services. The P2P shift will impact many areas of our lives, from mobile communication, human interactive web services, RTC and telephony infrastructure, user federation, security and privacy implications, business costs, and scalability. In his session at @ThingsExpo, Robin Raymond, Chief Architect at Hookflash, will walk through the shifting landscape of traditional telephone and voice services ...
Explosive growth in connected devices. Enormous amounts of data for collection and analysis. Critical use of data for split-second decision making and actionable information. All three are factors in making the Internet of Things a reality. Yet, any one factor would have an IT organization pondering its infrastructure strategy. How should your organization enhance its IT framework to enable an Internet of Things implementation? In his session at Internet of @ThingsExpo, James Kirkland, Chief Architect for the Internet of Things and Intelligent Systems at Red Hat, described how to revolutioniz...
Bit6 today issued a challenge to the technology community implementing Web Real Time Communication (WebRTC). To leap beyond WebRTC’s significant limitations and fully leverage its underlying value to accelerate innovation, application developers need to consider the entire communications ecosystem.
The definition of IoT is not new, in fact it’s been around for over a decade. What has changed is the public's awareness that the technology we use on a daily basis has caught up on the vision of an always on, always connected world. If you look into the details of what comprises the IoT, you’ll see that it includes everything from cloud computing, Big Data analytics, “Things,” Web communication, applications, network, storage, etc. It is essentially including everything connected online from hardware to software, or as we like to say, it’s an Internet of many different things. The difference ...
