Windows Server 2012 Powers the Cloud OS

New server is built from the cloud up for the modern datacenter.

Satya Nadella, president of Microsoft Server and Tools Business, announced the general availability of Windows Server 2012. In his keynote speech, Nadella described how Windows Server 2012 is a cornerstone of the Cloud OS, which provides one consistent platform across private, hosted and public clouds.

“The operating system has always been the heartbeat of IT and is now undergoing a renaissance in the new world of continuous cloud services, connected devices and big data,” Nadella said. “Microsoft’s unique legacy in the most widely used operating systems, applications and cloud services positions us to deliver the Cloud OS, based on Windows Server and Windows Azure, helping customers achieve a datacenter without boundaries.”

Enabling the Modern Datacenter

Microsoft built Windows Server 2012 from the cloud up, applying its experience operating global datacenters that rely on hundreds of thousands of servers to deliver more than 200 cloud services. Windows Server 2012 expands the definition of a server operating system, with significant new advancements in virtualization, storage, networking and automation. Hundreds of new features can help customers achieve a transformational leap in the speed, scale and power of their datacenters and applications. In combination with Windows Azure and System Center, Windows Server 2012 empowers customers to manage and deliver applications and services across private, hosted and public clouds.

Customers Find Success With Windows Server 2012

Customers can use their existing skills and investments in systems management, application development, database, identity and virtualization to take advantage of Windows Server 2012 and realize the promise of cloud computing. Many enterprise customers are already seeing tremendous value in early deployments. A survey of 70 early adopter customers from across the globe revealed that they expect, on average, 52 percent reduction in downtime, 41 percent reduction in workload deployment time, and 15 hours of productivity time saved per year, per employee. 91 percent of the companies surveyed expect a reduction in server administration labor, and 88 percent expect reduction in network administration labor.*

Menzies Aviation, an airline passenger and cargo handling company that employs more than 17,000 people, is using Windows Server 2012 to provide identity access management and information access policies to its employees as it rapidly incorporates newly acquired businesses.

“We are very impressed by Windows Server 2012 and Microsoft’s overall solution to help us manage our systems and applications across our private cloud environments as they scale with our business,” said Martin Gallington, senior vice president of IT at Menzies Aviation. “This is a dramatic leap forward, matched by a simple, cost-effective pricing model.”

Equifax is a global information solutions provider that organizes and assimilates data on more than 500 million consumers and 81 million businesses worldwide. It now counts on Windows Server 2012 for improved reliability and uptime of its information services to clients.

“Windows Server 2012 revolutionizes how we can operate our datacenter, allowing us to better meet our commitments,” said Bryan Garcia, chief technology officer at Equifax. “The new high availably technologies help us deliver ‘always-on’ applications, and we’re betting on Hyper-V as a critical component of our private cloud strategy. We are gaining tremendous efficiencies, which translate into more time to innovate for company growth.”

Welcome Windows 8

October 30, 2012 No comments

Microsoft has unveiled the long-awaited Windows 8 platform, an operating system which promises to take the computing experience to another level. This is probably the most important announcement in Microsoft’s history since the launch of its Windows 3.0 in 1990. This is not just a product announcement; it is a new strategic direction that will redefine the way computers are used.

The goal here is to move away from the ageing PC paradigm where the user experience is designed and locked into desktops and notebooks. Microsoft is now promoting the “Personalized Computing Experience”, where the experience is no longer attached to a computer but defined as a framework tailored to the user’s needs regardless of the nature of the device being used.

It is becoming clear that the PC market, the core business of Microsoft, is shrinking. This is due to both cannibalization by the tablet market and the slow PC replacement cycles. Consumers are not prepared to upgrade their PC hardware unless major enhancements in terms of both performance and user experience are offered. It is striking that almost a third of all PC users are still using Windows XP, a version launched more than 11 years ago. In addition, major OEMs are now shifting their interests away from the relatively low-margin PC business and focusing on areas where they can differentiate their products.

The popularity of tablets and smartphones clearly indicate a major shift in the way users interact with their devices away from the keyboard and the mouse. Touchscreen and, increasingly, gesture and voice recognition have emerged as alternative interfaces currently enabling the creation of a plethora of innovative applications and services that have made smartphones and tablets very popular. Previous versions of the Windows platform were not designed for a multi-touch experience but Windows 8 is likely to change the game.

The aim of Windows 8 is to enable users to run their applications and services across various devices regardless of either the input/output method used or the screen size of the device. This also very important for developers as they will be able to target a wider audience of users using the application development framework and the same set of APIs. It will also enable Microsoft to grab new opportunities in markets that it was not able to tap into before, including tablets, smartphones, set-top boxes and other consumer electronics devices.

Windows 8 strategy will enable Microsoft to adapt its business to the demands of touchscreen as an ultimate input method for modern computing devices. However, it could take a long time for Microsoft to migrate all its customers to touchscreen due to the PC market’s slow replacement cycles.

Microsoft’s long-term strategic goal is to enable multiple UIs (e.g., keyboard, touch, gesture and voice in the future) for all computing devices – PCs, laptops, tablets and smartphones. The company will want to accelerate the move from the traditional “touchless” computing landscape to multi-UI computing but it is not clear how successful it will be in achieving this goal.

The unified user experience of Windows 8 across various types of device also faces a number of challenges, most notably in the mobile market where Microsoft is a new entrant. How will the software giant manage its partnership with mobile OEMs and create a single marketing message? How will it aligning its platform roadmap with reference designs and points of differentiation of the various vendors? These are not simple tasks, they will require significant investment in terms of time, money and human resources.

Network Administrator

October 30, 2012 9 comments

As a network administrator, your tasks generally fall into the following areas:

Designing and planning the network
Setting up the network
Maintaining the network
Expanding the network

Each task area corresponds to a phase in the continuing life cycle of a network. You might be responsible for all the phases, or you might ultimately specialize in a particular area, for example, network maintenance.

Designing the Network

The first phase in the life cycle of a network involves creating its design, a task not usually performed by new network administrators. Designing a network involves making decisions about the type of network that best suits the needs of your organization. In larger sites this task is performed by a senior network architect: an experienced network administrator familiar with both network software and hardware.

Setting Up the Network

After the new network is designed, the second phase of network administration begins, which involves setting up and configuring the network. This consists of installing the hardware that makes up the physical part of the network, and configuring the files or databases, hosts, routers, and network configuration servers.

The tasks involved in this phase are a major responsibility for network administrators. You should expect to perform these tasks unless your organization is very large, with an adequate network structure already in place.

Maintaining the Network

The third phase of network administration consists of ongoing tasks that typically constitute the bulk of your responsibilities. They might include:

Adding new host machines to the network
Administering network security
Administering network services, such as NFS^TM services, name services, and electronic mail
Troubleshooting network problems

Expanding the Network

The longer a network is in place and functioning properly, the more your organization might want to expand its features and services. Initially, you can increase network population by adding new hosts and expanding network services by providing additional shared software. But eventually, a single network will expand to the point where it can no longer operate efficiently. That is when it must enter the fourth phase of the network administration cycle: expansion.

Several options are available for expanding your network:

Setting up a new network and connecting it to the existing network using a machine functioning as a router, thus creating an internetwork
Configuring machines in users' homes or in remote office sites and enabling these machines to connect over telephone lines to your network
Connecting your network to the Internet, thus enabling users on your network to retrieve information from other systems throughout the world
Configuring UUCP communications, enabling users to exchange files and electronic mail with remote machines
