Mobile Strategy
This paper your organization has an established market and accepted the business case for mobility and you are ready to proceed. When you implement a mobility solution, the effects are not limited to the actual consumers, but also the subtle and long-term effect on your IT strategy and execution. Over the past ten years we have seen the level of IT infrastructure from a private internal to increase information to the outside public access publishingon the Internet. It 's time to deal with the provision of external access to internal information systems and have to deal with a new set of questions about how to support a wide range of mobile devices? How to manage access to information on internal systems of these devices? We provide a safe and reliable?
The opening of business systems to mobile users requires careful planning to avoid the effects of changes in order to reduce the principal stakeholders, end users and IT management. A strategyMobility must watch include the following areas:
Mobile devices and device management
Communications (wireless and wireline), protocols and costs
Mobile applications individually and Usability
back-office data such as data requirements and integration points
central platform for mobile access, how the data in the mobile Internet
Security for authentication and encryption
Solution delivery and pricing models
The desired result of the analysis of these points represent the functional requirements, ease of use and structural engineering, as the architecture of mobile system for your business. The considerations of these issues are discussed in this paper.
Devices and equipment
The pace of technology for drivers coming onto the market continues to climb, sales of notebook and laptop now surpassed sales of desktop PCs and the billions of mobile phonesare sold more and more data applications can. There is also a full range of equipment in the cross-over between these two extremes, consisting of smart phones, PDAs, handheld bivalve, tablets, and more. This is a seemingly unlimited number of less form factors, different screen sizes, some rotating input methods (keyboard, keypad, stylus, finger, scanner for bar codes and RFID, voice, and more), type of and processor performance, memory size of kilobytes per gigabyteruggerdised construction and not the least of operating systems and application environments.
From the point of view of the device selection is the only safe rule to expect a mixed environment of today's standard equipment is likely to be available in 24 months. However, minimizing IT costs and resources is the adoption and application of the rules, so what's the solution? For mobility, is the answer to that device that fits the needs of end users select and use aDevice mobility management platform, leading to all units of the fleet. The platform abstracts the management of mobility devices, hidden individual differences.
A mobility platform must enable device management for enterprise applications, including the configuration of communication devices and updating applications on a single user or user group.
Communications
In many respects, mobile applicationsreplace the current manual paper-based systems can obviously only need a limited method of communication for exchange of data from back-office systems. However, a simple request because this option may cause too, could be given a user connects the device to a modem to dial telephone, intranet or even a PC sync connected, or if a wireless network or used as a mobile WiFi hotspot ? Each method has its cost, performance and latency, availability,Investments in infrastructure and security ramifications.
advanced mobile applications that require more immediate and require the collaboration of solutions push function, back-office notifications in real time to return the product.
Create or purchase of mobile applications that run efficiently on a network of communication selected as a wired LAN can perform badly when you switch to a wireless network. Conversely, if low-bandwidth optimizedlatency high-up or wireless mobile network to settle the same question you can not use his generation, wireless networks, high bandwidth, or third parties.
The best approach is to select the most appropriate communication network (s) for the purposes of the application and use a mobility platform that removes details of the communication by the application. A Wireless Application Gateway (WAG) to handle communications between the device and back-office will beOptimization of communication. It also provides a function of added value, such as support for push notification and independent compression of the selected network.
How to access client
cable networks that have been around for decades, a relatively high speed and reliable communication channel to the back-office systems with different models of large existing enterprise applications such as Thin Client Terminal (Citrix, Web) and multi-tier (client, server and database logic levels)Thick clients. The separation between the presentation of the request and the user is essentially a choice of IT management and a key driver for the model. Both models tend to take more than one communication link is to manage the integrity of transactions (record locking) and the sharing of resources in real time.
For mobility, with its unreliable nature of communication, it is time to reassess the models of appropriate access. The networks are in power, however, increases the inherentType of wireless range means that it will never be omnipresent and disturbances are still clearly the terms of latency of wired networks, applications running on the wired network for the good does not work, probably well over W-LAN in all.
To choose the two most common methods between a thin or thick client model. Thin clients are typically a Web browser or a specially built as a Citrix client, where the network must be available forthe required function. This thin client solutions have been a number of enterprise mobility solutions because of the limited capacity of the Web browser for mobile devices and frustrating usability problems for the ultimate success. thick client offering quick response and improved user interface, but they suffer the burden of administration and distribution of the update.
This in turn provides a platform for mobility solutions as the best of two models, the model called "intelligent" client. This allows the optimsiedThe thick client experience with the dynamic performance of thin clients. Applications and forms, mobile devices can be used to dynamically provide the latest features to install, without the administrative burden of updating each device or find the 'software that is.
Mobile Applications
Most organizations have invested in their employees' data collection processes and back-office systems is difficult to find a ready-made mobileThe request will be an exact match. The most common is an existing application and retrain staff to meet, or a custom solution that is tailored to create and grow as demand for organizational needs.
The choice of a platform that is rich, but simply can deploy toolkit for creating mobile applications, which is essential for success. The application can then mirror the current forms and processes that help reduce the impact of changes to end users. The toolkit includes must approachnot only the user but the data structures and communication to back-office, as well as having a one-stop location for the construction of a complete solution.
Many IT projects fail or higher, as were its development budget software races, underestimated the complexity or the original requirements are unclear. A platform, mobility for non-programmers, such as the objectives of Business Process Engineers, keeps the focus on solving business. In addition to a coupled device managementPlatform is the ability to easily implement new versions of the scope for rapid testing and user acceptance.
Systems Integration
Often referred to standards is that there are many to choose from and that's not true that with Enterprise Application Integration (EAI), in which each system or group of systems in particular, are protocols for exchanging data, usually from the file simple text import / export of complex informationMessage Broker bus. New rules will continue to log on as the data requirements and change management to take new opportunities.
Designing mobile applications to communicate with a specific back-office system appears to be the easiest and fastest way to move forward, but to create these blocks in a particular protocol is a server problem when the system is changed or newly updated. Instead, the construction of mobile systems, on the loose on the back-office system is connectedessential for success.
A mobility platform is a set of integration capabilities that are independent of mobile applications and change through the IT administration. The integration options should, because the data are presented and insisted (as raw text files and XML) and protocol for the common use (such as the actions of network drives, FTP, HTTP, and Enterprise Message Broker). full audit logs are needed to determine a history of dataIntegration.
Security
Computer security system the highest priority and the security information about the company faces. The growth of Internet technologies for access to content with the development of encryption, authentication and identification associated. Enterprise Firewall, Virtual Private Networks (VPN), intrusion detection, centralized authentication server, the standard to keep out intruders.
Mobility can affect a numberThis system of safety standards and therefore undermine the protection of corporate networks that allows users to obtain unauthorized access vulnerabilities, or to obtain business information from a mobile device is lost of stolen. Security options must be applied on the mobile device and in communication with the company.
A mobility platform should provide data synchronization and access over secure channels, such as HTTPS or VPN. multi-factor authentication of the user and the deviceas the use of unique identification ID of the device or network built SIM (Subscriber Identification Module) cards or network functions such as caller.
From a planning application data should only be stored on the mobile device and other data can be entered.
Server
Mobile applications require an application gateway for communicating, which will provide back-office application services are always available. This in turn requires that theGateway runs on an operating system stable and scalable application server. This is also integrated into the corporate network to authenticate users and access to data in back-office. You should be able to grow with increasing demand for transactional mobile access to data and back-office. The application should be based platforms in a scalable architecture and industry standards are used, such as J2EE o. NET architecture. These architectures can provideCompany or carrier performance and reliability.
The administration should be the mobility platform is a server and user management roles for delegated tasks in the IT team to do. Remote access to the server via the Web, offers easy access to the system without installing client.
Solution Delivery Options
With the growth of the Internet, e-mail there was growing acceptance of the benefits of outsourcing data processing systems for high availabilityand remote access to systems without depending on other infrastructure. This is also the case of wireless application gateways, and operational requirements and costs of care for the following licenses:
Application Service Provider (ASP) - capital expenditure limits, system maintenance, etc. (great for non-IT company). Do not grow the business and is not an investment decision, but the operating costs.
Managed Service - RelatedASP, but requires investment in hardware, the company, but the source management and control.
Software - The most common model of software licenses today, the investment in hardware, software licenses and ongoing operations are managed in-house needs. Both ASP and managed services, an inexpensive and quick to market capacity. The mobility platform and service provider, offering a flexible solution that can be startedfast business benefits can be assessed.
Conclusion
This work has demonstrated a number of technical areas that are pulled before the addition of a mobile extension to the corporate network into account. This information can be used to comprehensively assess the capabilities of the gateway applications available on the mobile market. The gateway will be selected for the company, have a history of proven solutions and practical with a change in course that is coupledContinuous investment in the future progress of cellular technologies.
