Migration Considerations for Windows 8 Style Apps

Reimagine your apps

There is a famous saying "Imagination is the creativity behind all innovations."

In today's world where there is a plethora of smart devices to the market, the growth of smart devices is changing our work patterns. Enterprises are looking to build a solution that will give unified experience across all devices and stay connected on their personal device around the clock - whether in the office, at home or traveling. The enterprises are facing challenges to build apps that follow the principle of write-once and run-anywhere, any-device - smartphones, tablets, desktops or laptops without managing separate code-base.

Welcome to the world of Windows 8. It addresses these challenges. Windows 8 brings touch screen experience and deployment across multiple devices and anytime anywhere connectivity out-of-the-box. Windows 8 style apps enable developers to provide uniform end-user experience across all the supported Win RT devices. This article explains the key considerations for the migration of existing applications.

Windows 8 Overview
Windows 8 introduces a new STYLE UI design system interface that was first introduced in the Windows 7 Phone mobile operating system. The new user interface flashes a "Start screen" with Applications in the form of "Live Tiles". Users will also be able to shift between apps by swiping the screen. New windows 8-style apps have a brand new look and feel, run on multiple devices, and download these apps from the Windows 8 store. These apps follow write-once and run-anywhere, any-device principle. The following table describes some of the salient features of Windows 8 apps:

Integration Patterns

App-to-App, App-to-Cloud, Enterprise-to-Cloud

Deployment and Lifecycle Considerations
There are two options to deploy Windows 8 applications to customers; "Windows Store" is the best place to distribute applications to the broadest set of customers. "Direct Distribution" is suitable for custom and proprietary line-of-business apps within the enterprise. Windows 8 is also using new lifecycle events to make apps always feel alive, improve performance and reduce battery usage.

Feature

Description

App Store

Windows 8 Application Package supports multiple devices compatibility, this package can be downloaded from Windows store and deploy in any Windows 8 compatible devices. Microsoft certifies the App Store Deployment & publishing process

App Install, Update & Removal

No manual interaction is required for App Install/Update process. Users will be notified for updates and Apps are automatically recycled

License & Pricing Models:

Windows Store offers different pricing models, and rewards to popular apps. Collect full price, Time-limited, Feature-limited, In-app and Third-party transactions are options to bill customers.

Optimize memory & battery-life

Apps are "one-at-a-time" compatible, OS manage the background activities. Apps have 3 states - Running, Suspend, NotRunning

Suspend

New Windows 8 style Apps stop running when the user switches to another App. Windows suspends App when it is not in the foreground. When App is suspended, it is frozen in memory

Resume

When App is resumed, Windows 8 OS continues from the state where it was suspended it. User don't need to restore any saved data explicitly when receiving the resuming event

Windows 8 brings a whole bunch of smart-capabilities; while it is possible to develop apps that follow the principle of write-once and run-anywhere, any-device - smartphones, tablets, desktops or laptops; it comes with an additional engineering cost and effort. Therefore, it is recommended that you evaluate the cost-benefits of migration based on the convenience and needs of a given app across devices.

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.

As more intelligent IoT applications shift into gear, they’re merging into the ever-increasing traffic flow of the Internet. It won’t be long before we experience bottlenecks, as IoT traffic peaks during rush hours. Organizations that are unprepared will find themselves by the side of the road unable to cross back into the fast lane. As billions of new devices begin to communicate and exchange data – will your infrastructure be scalable enough to handle this new interconnected world?
The Internet of Things is in the early stages of mainstream deployment but it promises to unlock value and rapidly transform how organizations manage, operationalize, and monetize their assets. IoT is a complex structure of hardware, sensors, applications, analytics and devices that need to be able to communicate geographically and across all functions. Once the data is collected from numerous endpoints, the challenge then becomes converting it into actionable insight.
Contrary to mainstream media attention, the multiple possibilities of how consumer IoT will transform our everyday lives aren’t the only angle of this headline-gaining trend. There’s a huge opportunity for “industrial IoT” and “Smart Cities” to impact the world in the same capacity – especially during critical situations. For example, a community water dam that needs to release water can leverage embedded critical communications logic to alert the appropriate individuals, on the right device, as soon as they are needed to take action.
As more and more data is generated from a variety of connected devices, the need to get insights from this data and predict future behavior and trends is increasingly essential for businesses. Real-time stream processing is needed in a variety of different industries such as Manufacturing, Oil and Gas, Automobile, Finance, Online Retail, Smart Grids, and Healthcare. Azure Stream Analytics is a fully managed distributed stream computation service that provides low latency, scalable processing of streaming data in the cloud with an enterprise grade SLA. It features built-in integration with Azur...

WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.
Through WebRTC, audio and video communications are being embedded more easily than ever into applications, helping carriers, enterprises and independent software vendors deliver greater functionality to their end users. With today’s business world increasingly focused on outcomes, users’ growing calls for ease of use, and businesses craving smarter, tighter integration, what’s the next step in delivering a richer, more immersive experience? That richer, more fully integrated experience comes about through a Communications Platform as a Service which allows for messaging, screen sharing, video...
