Pros and Cons: Should You Upgrade Your Office to Windows 8?

While the jump to Windows 8 might not be a huge deal for the average consumer, the change is a big decision for businesses — both small and large. From IT departments managing hundreds, or even thousands of computers, to employees in sales or marketing that rely on their computers to get their jobs done, there’s a lot to think about before upgrading. Here are some of the pros and cons of the new OS to help you decide whether your business should upgrade to Windows 8.

Pro: The New Interface

Say goodbye to the Start menu! Windows 8 sports a radical new look and feel that was once called “Metro” (and people are bound to keep calling that even though Microsoft retired the name). First seen on the Windows Phone and the Xbox 360, the new user experience is a colorful and boxy design that uses tiles to provide you with relevant information at a glance.

These tiles update in real-time to show you upcoming calendar events, incoming tweets, and even the weather report. When you switch over to a tablet or mobile device, you’ll be presented with the same tiles, allowing you to swipe between screens and apps with ease.

An added benefit of the new user interface is much better support for multiple monitors. Robust settings will allow you to customize things like the display of each individual monitor, its desktop backgrounds, and multi-monitor slide shows. And some studies have shown that some types of employees perform better with multiple monitors if you’re willing to make the investment. Being able to take your information with you wherever you go and having an at-a-glance view of key applications will be invaluable for businesses that need to consume data quickly.

Pro: Unified Experience

While Metro provides a new aesthetic in the form of a welcome new design refresh to Windows, there’s an even bigger bonus here. The new design eliminates clutter and ties different aspects of the operating system together in ways that we have not really seen before with Windows.

There is now built-in compatibility across a wide range of devices beyond just your typical desktop computer or workstation. The Windows 8 experience can be expanded to tablets and smartphones; powerful sync tools lets you take your apps, preferences and more with you wherever you go. Windows 8 also offers single sign-on to all your devices — a big plus for business users who are always traveling.

Pro: Better Performance

Windows 8 was designed from the ground up to provide a snappier operating system that takes advantage of the latest advancements in hardware and processing tools. When Microsoft released the Consumer Preview version of the OS a few months ago, many were surprised just how fast Microsoft had made Windows 8. Shaving seconds off most tasks, computers running Windows 8 will be able to start faster, load programs quicker and manage tasks more efficiently with an overhauled Task Manager.

Along with better performance, Windows 8 comes with more responsible energy usage as well. Early reports indicate that you may be able to squeeze a little more time out of your laptop battery thanks to improvements made at the system level to Windows 8. When idle, the OS will drop down into a very low power usage state to save energy and conserve battery life.

Pro: Easy Application Development Process

It is very easy to develop Metro applications for Windows 8. The only languages a developer would need to know are JavaScript, CSS, and HTML5. These languages are simple and quick, which means developers will create new applications efficiently.

Pro: Microsoft App Store

Microsoft is releasing its own App Store along with Windows 8. Not only will developers be able to create apps quickly, but now they all have a central hub through which to distribute them. Despite how good the Microsoft App Store sounds, one must remember that Microsoft has tried something like this before and failed. Will this be another flop?

Pro: Improved Task Manager

The Task Manager in Windows 8 has been majorly improved with a focus on ease of use for regular users without reducing its usefulness for power users. For regular users, the interface has been better organized and designed to be more intuitive. Upon startup, the only thing the user will see is a list of running applications and applications that are not responding. The Processes, Services, Performance, Networking, and Users tabs have been stowed out of sight. Now you can just select an application and click End Task, and the application immediately closes without prompting. Power users can click More Details and an improved selection of the aforementioned tabs will be displayed.

Con: Steep Learning Curve

 

In the business world, Windows has been the norm for many years. While the operating system has seen a host of updates, the way people use it hasn’t really changed that much. If you’re operating a business and thinking of taking the jump to Windows 8, expect a bit of a learning curve for your staff.

Windows 8 does away with the traditional task bar and features a completely new ribbon-based interface for first-party applications. Those using recent versions of Office, or using a tablet running Windows 8 might feel right at home. However, a majority of people will need some form of training to get up to speed on the many changes and enhancements being offered.

Con: Windows 7 Isn’t That Old

The last major consideration to take into account is the relative recency of the Windows 7 operating system. Some companies’ IT departments are still trying to work out the kinks of the migration to Windows 7. Enterprise businesses may have a hard time justifying yet another upgrade that will take computers offline. There are also training requirements and costs to consider.

Con: No Start Button

Since Windows 95, the Start button has been with us, and is something that some might argue has made Windows Windows. The Start button is even where the Microsoft logo has been harbored for 17 years. To many users, it seems sacreligious to eliminate such a long-lasting icon so unceremoniously. Does Microsoft have no respect for tradition and nostalgia?

service-oriented architecture (SOA)

is a set of principles and methodologies for designing and developingsoftware in the form of interoperable services

SOA generally provides a way for consumers of services, such as web-based applications, to be aware of available SOA-based services. For example, several disparate departments within a company may develop and deploy SOA services in different implementation languages; their respective clients will benefit from a well-defined interface to access them. XMLis often used for interfacing with SOA services, though this is not required. JSON is also becoming increasingly common.

Types of(SOA) :

Four common SOA types have emerged in order to improve physical design.[11]Documenting architecture types encourages services that are more standardized, interoperable and composable. This also assists in understanding interdependencies among services.

Service architecture

This is the physical design of an individual service that encompasses all the resources used by a service. This would normally include databases, software components, legacy systems, identity stores, XML schemas and any backing stores, e.g. shared directories. It is also beneficial to include any service agentsemployed by the service, as any change in these service agents would affect the message processing capabilities of the service.

Service composition architecture

One of the core characteristics of services developed using service-orientationdesign paradigm is that they are composition-centric. Services with this characteristic can potentially address novel requirements by recomposing the same services in different configurations. Service composition architecture is itself a composition of the individual architectures of the participating services. In the light of the Service Abstraction principle, this type of architecture only documents the service contract and any published service-level agreement (SLA); internal details of each service are not included.

If a service composition is a part of another (parent) composition, the parent composition can also be referenced in the child service composition. The design of service composition also includes any alternate paths, such as error conditions, which may introduce new services into the current service composition.

Service inventory architecture

A service inventory is composed of services that automate business processes. It is important to account for the combined processing requirements of all services within the service inventory. Documenting the requirements of services, independently from the business processes that they automate, helps identify processing bottlenecks. The service inventory architecture is documented from the service inventory blueprint, so that service candidates can be redesigned before their implementation.

Service-oriented enterprise architecture

This umbrella architecture incorporates service, composition and inventory architectures and any enterprise-wide technological resources accessed by these architectures e.g. anERP system. This can further be supplemented by including enterprise-wide standards that apply to the aforementioned architecture types. Any segments of the enterprise that are not service-oriented can also be documented in order to consider transformation requirements if a service needs to communicate with the business processes automated by such segments.
