Drive even greater efficiency with virtualisation

Fri, 07/30/2010 - 16:45
Third in a series of three Forrester Consulting thought leadership whitepapers

This report examines the transition from a period of Strategic Consolidation to one of focused Process Improvement, stages two to three in Forrester’s Virtualization Maturity Model. Through in-depth interviews with numerous IT professionals across North America, Europe, and Asia Pacific, Forrester found that those companies that had changed their operational processes to reflect the unique needs of a virtual infrastructure achieved higher return on investment, greater administrator productivity, more predictable deployments, and simpler problem identification and resolution than those that had simply virtualized and stuck with traditional procedures.

Second in a series of three Forrester Consulting thought leadership whitepapers

Through in-depth interviews with numerous IT professionals across North America, Europe, and Asia Pacific regions, Forrester found that those companies that took a holistic rather than a piecemeal approach to their virtual infrastructure were able to dramatically increase infrastructure consolidation gains and improve their flexibility, responsiveness and resiliency — at a cost they could afford.

The ROI of application delivery controllers in traditional and virtualised environments

Wed, 07/28/2010 - 15:24
Realise the benefits

Whether you are looking to consolidate physical resources and create a virtualized data center, or you’re sticking with a tried-and-true traditional architecture, the ability to forestall additional capital expenditures through the implementation of server offload techniques can only improve your financial efficiency—while maintaining or even improving availability, capacity, and performance. And with the anticipated growth of virtual machines per server, it is imperative to ensure that each application deployed within a virtual machine is as efficient as possible.

Creating a hybrid ADN Architecture with both Virtual and Physical ADCs

Wed, 07/28/2010 - 14:55
Recommended best practices

The virtualisation of network and application network infrastructure is the second wave of the virtualisation tsunami to hit the shores of the data centre. Unlike server virtualisation, because of its unique role in the data centre, Application Delivery Controller (ADC) virtualisation brings with it architectural implications that make a simple vitual-for-physical replacement strategy unacceptable. But there are appropriate places across the data centre and organisation where virtualised ADCs can be leveraged as stand-alone solutions, as well as in conjunction with its physical predecessor, to enable a more dynamic data centre without compromising reliability, scalability, and performance.

A green architectural strategy that puts IT in the black

Wed, 07/28/2010 - 14:38
Implementing a more efficient green strategy

Most green initiatives thus far have focused solely on reducing the power requirements of individual devices. While that is certainly a valid approach to reducing power consumption, it does not affect other variables in the green equation such as the power required to cool a data center or the power provided to racks upon racks of servers.

Wireless LAN virtualisation

Mon, 07/26/2010 - 16:15
Twice the network at half the cost

Creating networks that can run business-critical applications is one of the core focuses of the enterprise IT department. This has traditionally meant wired Ethernet, with wireless often seen as an afterthought for convenience rather than the network of choice. But as aging wired infrastructure approaches its next expensive refresh cycle and users demand mobility IT departments are looking for an alternative. In uncertain economic times, a networking technology that radically cuts per-port costs and eliminates most cabling would seem to be ideal.

The foundation for wireless without compromise

Mon, 07/26/2010 - 15:57
Enterprise wireless networking

The last decade of the 20th century witnessed the use of Internet. The first decade of the 21st century has seen the rise of wireless connectivity. Wireless networking is now commonplace—mobile connectivity is becoming a rule, not an exception. But getting there was not as easy as it may seem today. Wireless networking requires a basic understanding of the world of Radio Frequency (RF)— where concepts like channel planning, cell sizes and frequency reuse are the norm.

Flexible working for efficiency and effectiveness

Following the May 2010 general election and resulting budget cuts, the UK public sector faces the toughest challenges in decades. Adoption of leaner, more agile work styles, implementation of mobile and flexible working solutions and some strong executive leadership will be called for if the sector is to continue delivering the required levels of public services while producing the many billions of efficiency savings that will be expected of it.

The value of video communications

Mon, 07/26/2010 - 14:51
Realise the benefits

The report begins by reviewing the classic approach comparing the service as a substitute for business travel. By looking at three distinct classes of business travel - day trips, overnight trips and week-long trips - Brockmann & Company developed a Demand curve for each class of substitution. We then review the value of the service with respect to the more mature audio conferencing and web conferencing services.

Making the right choice for your organisation

Telepresence is the latest in a long line of visual communications technologies that have promised to revolutionise corporate collaboration. But can the new technology meet the complex and demanding needs of today’s organisations for reducing costs, improving productivity, and realising their environmental responsibilities—or is it just another example of a solution looking for a problem?

Video conferencing guide

Did you know that 55 percent of communication is determined by nonverbal cues — namely tone of voice and body language?1 How many of these important nonverbal details get lost everyday in email exchanges or teleconferences? Face-to-face communication is more personal. It builds a higher level of trust, reduces confusion and makes people more accountable for their actions.

New opportunities from new ways of working

Fri, 07/23/2010 - 15:31
A revolution in the workplace

The office as we know it is in danger of becoming extinct. Cancelled meetings, endless commuting and the enormous expense of renting desk space that’s idle for 16 hours a day have long been wasteful practices. It’s only now that more and more people are starting to realise this. The companies of tomorrow will change the face of the ‘traditional’ employee too. More emphasis will be put on an employee’s area of expertise rather than the idea of a job for life.

An enterprise guide to understanding key management

Wed, 07/21/2010 - 16:23
Take a proactive approach to data protection

A policy-based approach to key management provides the flexibility and scalability needed to support today’s dynamic networking environments. Policy-based key management ensures the secure administration of keys throughout their entire lifecycle, including generation, distribution, use, storage, recovery, termination, and archival. This will also enhance business processes and relieve often over-burdened IT staff by breaking down the “islands of security” and “security silos” that are too often typical to enterprise environments.
