Virtualisation: a great way to cut costs and stay ‘green’?

The cloud has been a godsend for many cash-strapped businesses in today’s wobbly economy by providing ‘pay-as-you-go’ pricing and lowering IT infrastructure costs. Whilst often overshadowed by its headline-hogging sibling, however, I believe virtualisation is just as capable of delivering ‘green’ and cost-cutting benefits.

Rather than paying for racks of under-utilised servers each devoted to a specific task, virtualisation allows you to group workloads on a smaller number of fully-occupied devices. This yields a better ROI on your hardware and saves additional cash as it requires less management, consumes less energy and takes up far less space. Indeed, businesses who’ve virtualised their systems regularly report IT savings of 20% or more.

Business continuity is both helped and challenged by today’s top tech megatrends

, failure is not an option. Not surprisingly, organisations have made it a high priority to develop and implement reliable business continuity plans to ensure that IT services are always available to internal users and outside customers, says Bob Violino on CSO Online.

But recent technology developments and trends, most notably server and desktop virtualisation, cloud computing, the emergence of mobile devices in the workforce and social networks, are having an impact on how enterprises handle IT business continuity planning and testing. Much of the impact is for the better, experts say, but these trends can also create new challenges for IT, information security and risk management executives.

Are you being careful not to virtualise waste?

by Paul Curran

Server virtualisation has been hailed by many analysts as the panacea for operational efficiency, lower IT costs and reduced carbon footprints. Indeed, Gartner went as far as to say the effective use of virtualisation technologies can reduce server energy consumption by up to 82%.

But let’s forget the impressive statistic for a moment and focus instead on their use of the word ‘effective’; for therein lies the reason many businesses, having embraced virtualisation, then fail to realise the anticipated savings.

The next frontier in virtualisation

Desktop virtualisation is becoming increasingly attractive to enterprises, particularly mid-sized businesses that have achieved significant data centre efficiency improvements through server virtualisation.

However, while server virtualisation mainly concerns back-end server consolidation, the move to desktop virtualisation involves re-architecting major parts of the IT system and making big investments in server hardware and network infrastructure, virtualisation management software and virtual application licences. The return on investment tends to take several years, reports Computer World.

Nevertheless, an increasing number of organisations are investigating desktop virtualisation technology, which can bring a whole host of IT and management benefits.
