Software as a Service: Web Apps and the MS Office Suite

Emerging Technologies - Strategies and Decisions

The next hardware driven wave of computer technology has commenced. According to leading industry studies, the dynamic growth of desktop personal computing is over. Smartphones and tablet computing devices capable of running software applications have been outselling PCs.

SaaS- Desktop-Mobile_Devices

The common foundation driving the evaluation and selection of the next generation of computer applications will be: 1- Featureset and quality of the software. 2- The improvement in employee productivity or reduction in software licensing cost. 3- Effective strategies for managing the implementation and realizing a return on investment. Organizational enterprise is facing an entirely new set of assumptions regarding how to manage, upgrade, and migrate their existing computer applications infrastructure. There is a business case to utilize and integrate the free and low cost open source operating systems and applications with Microsoft software. Software as a service and web apps which run on web browsers and platforms other than the Microsoft Windows operating system family and MS Internet Explorer/Edge web browser will have to be accommodated.

SaaS: Software as a Service provides network-based access to commercially available software: Microsoft 365, Google Docs,, and It also presents new opportunities for software vendors: 1- Ease and efficiency of deployment. 2- Increased user adoption. 3- Reduced support requirements. 4- Lowered cost of implementation and upgrades. According to Gartner research, more than 76% of American corporations use at least one SaaS applicaiton. Some 45% of companies spend 25% or more of their IT application budget on SaaS. As HTML5 becomes broadly supported in web browsers, SaaS applications will have a more interactive user experience.

Mobile Computing and Web Apps

Mobile devices and web apps present new capabilities through web browsers, mobile operating systems, and OSS: Open Source Software. The leading smartphone platform in terms of global units sold is the Google Android OHA: Open Handset Alliance platform; Samsung, HTC, Google/Motorola, and Sony Ericsson. In the aggregate this translates into market leadership. The Apple iPhone is the single most popular smartphone. The MS Windows Phone is no longer available and had negligible market share in the United States. Sales of the Windows smartphones in Europe show promise. In 2013, Microsoft acquired the handset and services business of Nokia in an effort to position Microsoft as a more prominent player in mobile computing devices. Microsoft has been playing catch up in 1- hardware with multicore processors, 2- operating system platform and interface, and 3- web app ecosystem.

In tablet media, the Apple iPad is the leader; the Apple iOS operating system platform is highly respected in terms of quality and developer support. Google acquired patents with its purchase of Motorola Mobility which allow for significant improvements in the integration and performance of its Google Android and Chrome operating systems with third party manufacturing of phones, tablet computers, and consumer devices. Samsung is the market leader in terms of units sold of Android smartphone and tablet computing devices.

PC Desktop Operating Systems and Web Browsers

Microsoft Windows 7 surpassed XP as the the most widely used desktop operating system. As the extended support phase of MS Windows XP makes it more expensive to continue with a MS Windows desktop foundation infrastructure, organizational enterprise will have to make an investment in Windows 8 and then move to Windows 10. MS Windows Vista adoption peaked in the fourth quarter 2009 and its utilization also has continued to steadily decline as part of the Microsoft Corporation operating system and Windows 10 desktop and mobile device platform incentivized consolidation strategy. Microsoft 10 will be the desktop standard and used to servicize virtualized desktop and web browser operating systems. There also will be challenges in supporting the Windows 7 - 10 desktop operating systems in conjunction with device and operating system diversity: smartphones, tablets, and BYOD devices. Web browsers increasingly are being used to execute applications and manage data. Microsoft has transitioned a replacement of its Internet Explorer web browser to Edge. Both the Google Chrome and Mozilla FireFox open source web browsers are being installed and used on Microsoft Windows desktop operating systems. In the fourth quarter of 2011, Chrome surpassed Mozilla Firefox as the second most preferred desktop browser.1  The Google Chrome and Mozilla FireFox open source web browsers provide reliable value which enhances and automates quality software. Google Corporation has been expending considerable resources to develop and distribute a service web apps ecosystem to serve as an alternative to Microsoft software. Google web applications can be accessed from a web browser. From the framework of an aggregate market definition - Microsoft Windows desktop, Linux-variants, and mobile devices, Google Chrome is the most widely installed global web browser. In 2018, a version of the Microsoft Edge web browser became available to be installed on Android and Apple operating system devices.

Mobile Apps and Systems of Engagement

Mobile devices and web apps draw upon an information technology infrastructure with immense data and information for empowering employees and engaging customers. A mobile app is a de facto website.  A well structured mobile app will: 1- Project business value with provisioning and support tools. 2- Accelerate efficient decision making with data dashboards. 3- Control and extend the value of smart products and services.

To meet these requirements, it will be important to have the governance and coding of the application software accurately aligned with the business model. The software architecture and presentation interface of the mobile app needs to provide an engaging user experience and be consistent with the database schema foundation. A common cause of problems with a mobile strategy occurs when the design architecture does not explicitly align with the engagement software, application management, and back-end systems of record. In many situations, it will be necessary to rework SOA: service oriented architecture to reduce message traffic and overhead for services originally designed for PCs on high speed networks or reface and re-architect middleware APIs to deliver task-oriented real-time response.  For large organizations, the complexity associated with developing and supporting multiple mobile platforms is accelerating a migration to cloud computing and adoption of software as a service.

Computer Applications Training by SYS-ED

SYS-ED is a leader in evaluating software and incorporating open source software into its MS courses and training programs. The subject matter, examples, sample programs, exercises, and validation assessment have been organized to provide guidance resolution in hybrid software environments.

Substantial investments have been made in both hardware and software infrastructure for running computer applications software. Computer applications software and more specifically the Microsoft Windows suite of integrated software and applications - Internet Explorer, Outlook, Word, Excel, PowerPoint, Access, Expression, and Project - have become the administrative foundation for the vast majority of organizational enterprise. The programmatic implementation of office and network administration tasks primarily has been with Microsoft languages and tools: batch file programming, WordBasic, Access Basic, VBA, WSH, and PowerShell.

  • New and better methods for inputting and data entry.
  • Style sheets and macros for word processing.
  • Web-enabling data for utilization with the Internet.
  • Integration of networking and search.
  • Programmatic presentation and exchange of data to local and remote locations.
  • Client- and server- side presentation and storage of information with scalable databases.

Our system consultant instructors are experts in designing and programmatically automating MS SharePoint with Excel, Access, and PowerPoint data presentation formats: HTML5 with XML and JSON. We provide specialized training services on hybrid combinations of commercial and open source web apps and mobile device operating systems.

Courseware is an important component of the SYS-ED training service. Textbooks are augmented with presentation slides and training aids. Subject matter and best practices from the CETi knowledge base are added selectively to courseware. Given the intermixing and hybrid implementation of commercial and open source software, reference material is fundamental to an effective training outcome.

The schedule on our websites reflects a projected time frame for licensure with the New York State Department of Education - Bureau of Proprietary School Supervision and submission and approval of curriculum.

Operational IT Challenges

The access and convenience of mobile devices and their integration and use is just beginning. Leading information technology research firms project that within 5 years there will be over one billion smartphones in the global economy. In excess of 350 million employees will be using smartphones and tablet computing devices in conjunction with performing operational tasks. 3 The challenge will be to provision and control mobile devices within a value-based app ecosystem.

1- Evaluate the low cost Google Docs and web apps open source application alternatives to the Microsoft Office Suite.
2- Evaluate the software as a service versions of Microsoft Office.
3- Invest in MS SharePoint Foundation and upgrade to MS SharePoint Server in order to provide a common framework for document management, repository for storing documents, and a platform for collaboration of applications.
4- Evaluate and test the mobile computing extensions to MS SharePoint Server: Google mobile devices and Apple iPhone and iPad; this will be part of establishing a BYOD: Bring Your Own Device program.
5- Evaluate and, if warranted, implement an open source Linux-variant operating system: Red Hat, Ubuntu, or SUSE.
6- Programmatically automate the Microsoft Office Suite using MS PowerShell, WAMP, and WIMP with web servers, scalable databases and the emerging mobile device development platforms.

XML: Extensible Markup Language has been developed to address electronic publishing problems. It defines rules to encode documents that are both human- and machine-readable. Microsoft Word documents, Excel spreadsheets, and PowerPoint presentations are stored in OOXML: Open Office XML. XML can work with jspm, linked data, documents, large databases, and the IoT: Internet of Things.

Mobile Device Platforms - Business Models in Transition

For the most part, smartphone and tablet computing will no longer be about device innovation; the driving impetus will be the web app ecosystem and service for gathering, analyzing, generating, and managing content. Consumer demand will determine the mobile market for devices, access and apps. Wireless access and mobile computing will continue to grow. There are now over 600 million private Wi-Fi hotspots. Public Wi-Fi also will continue its explosive growth. 4  Apple, Google, and Microsoft have emerged as the leading operating system and web app platforms for mobile devices. Each utilizes a different business model with respect to the integration of hardware and software and the web app development process. The resources and strategies being implemented by these companies reflect multiple target markets and businesses: selling devices and software to user populations, distribution of ancillary services, integration with information technology infrastructure, software as a service, and cloud computing.

The Google open source software model has led to specialized adoption of the Android operating system by Amazon in its Kindle and Fire e-readers and tablets and Barnes and Noble bookstore chain in its Nook e-reader series. There will be tradeoffs in costs, support and performance associated with native apps versus open-web-based apps. Native apps provide a targeted context specific experience and currently predominate. HTML5 provide cross platform extensibility to a larger market. There also are hybrid software technologies such as jQuery Mobile and PhoneGap. Over the long run the open web will become increasingly important.

FaceBook, YouTube, and Twitter are leading social engagement platforms that function through the web browsers of these ecosystems and also provide API programmatic extensions.

Mobile websites and mobile browser apps both utilize HTML, JavaScript, and CSS. However, there are significant differences in application development. 

Mobile websites are adapted presentations of web content optimized for smartphone and tablet screens. Websites use responsive design to dynamically adjust the layout and styling of content for viewing and consumption/interaction on any form factor. Mobile websites do not provide an app navigation experience; standard browser url, back button, and link navigation is used and depend on an active Internet connection to work. Content which normally is presented on a website is presented to a mobile user audience. A mobile website is an Internet connected server-side mobile app; a mobile website provides informational, read-only experiences.

Mobile web browser apps are designed to provide a native app experience. They use the same underlying technologies and delivery vehicle as mobile websites, but the user experience is different. Browser apps provide separate in-app navigation and are capable of working without an active Internet connection by using application caching techniques. Apps provide a task-based capability and apply the facilities of the mobile device.

Movement of user data between services can be complicated; commercial services are built differently and use different types of data that may require unique privacy controls. There now is a requirement to move among different kinds of services with the expectation that the companies also will protect their data. In 2018, Facebook, Google, Microsoft, and Twitter launched the Data Transfer Project open-source initiative to enhance the data portability ecosystem. As part of the project, member organizations will utilize open source code to provide a common framework that enables portability and interoperability.

Unlike prior capital expenditures in information technology infrastructure, there will be significantly more complexity. Improvements in the availability, transmission speed, bandwidth, and reliability of data, in conjunction with enhancements to computer hardware - storage, CPU, internal bus transfer speeds, and USB: Universal Serial Bus, have resulted in the development of software which competes with Microsoft's Windows desktop applications. Distribution will be in the form of software as a service through the Internet and cloud computing.
