Virtualization is sometimes viewed by certain companies with deep suspicion, often not understood properly and perhaps, even simplistically misinterpreted as ‘unreal’ and therefore, easy to dismiss. It’s argued that if data cannot be physically seen to be safely secured in a server locked in a room on the company premises, then they don’t want to know, end of!

The obvious error with this argument of course, is that the security of the computer network infrastructure itself, should be the principal object of concern, not by which work station, or in which cupboard the server stands. The problem for many businesses has been the loss of data because an accident, disaster or emergency has compromised the security and continued use of the operating system. The time and cost often involved with disaster recovery is predominantly, a direct result of compromised client side servers.

The concept of virtualization, whereby, a server is virtually partitioned into several sections, allowing each section to work individually, is not a new concept. The increased security is a result of the partitioned servers being isolated from one another, so that a problem affecting the one does not affect the others. A virtual server can be used to trap viruses and other malicious programs.

The adoption of virtualization and the reduction of the number of servers needed, has demonstrably delivered tangible benefits to daily business operating in numerous industries of all sizes. They consistently point to improved server utilisation, application management and availability to data backup, network security and protection.

In addition to reducing the amount of physical hardware, there is a corresponding reduction of energy consumption and generated heat in server rooms, and the opening up of valuable server rack space.

Of paramount concern always, is the ability for companies to significantly reduce the time spent daily on routine IT administrative tasks, including the ongoing development and launch of new applications. In today’s competitive, economic environment, outsourcing IT releases and refocuses valuable company resources to prioritise their other areas of urgent business needs.

Lack of budget and resources are often the most stated reasons given for companies holding back on implementing much needed IT streamlining, yet the reality of virtualization is you buy less hardware, which means saving on the costs of hardware purchase and maintenance.

Individualised local region IT support for virtual servers optimises multiple location business continuity because of partitioned server processing.

It is often assumed that Cloud computing technology is complicated, and therefore, expensive and only the ‘big boys’ can afford to play. However, in the decade or more since the cloud became commercially available, much has changed, and so called barriers to entry, say, for a startup or SME have simply evaporated as the online landscape has evolved.

The necessity for companies of all sizes to be able to have unlimited web access and be able to readily store and process ever larger and faster quantities of information in order just to remain competitive within their market niche has become ever more acute. The socially engaged web and the mobile internet is rapidly forcing the pace of change with inter communications running across multiple, integrated platforms and channels.

It may well have been that formerly, the multinational corporates had an advantage over more modest operations. Access to capital and command of existing human, software, and hardware resources all helped to retain their global edge by supporting new technological and strategic initiatives.

In today’s superspeed, geographically dispersed workplace environments, the balance of strategic advantage may have indeed tipped away from the large, established corporations towards the more nimble, small business service. The costs benefits of operating in the cloud vary depending upon the size of the enterprise, its existing IT resources/infrastructure and technical skill base. Leading cloud providers recognise a proactive IT policy across all work sector sizes is a key integral service component.

The trend towards the availability of open source software in nearly every software category has been a valuable aid to SMEs, the self-employed, and start-ups, whilst the larger enterprise are often dissuaded by licensing issues and feature considerations.

Cloud providers can today supply a software development dimension that include the requisite tools, code repositories, test environments, and access to a highly scalable production space on many attractive low cost and pay as you go options. A leading UK supplier should be able to offer 24/7 national IT support on a local level which translates to personalised problem solving, whether you need IT support Manchester or IT support Midlands as well as an IT support London.

The flexible advantage of cloud means that when data traffic volumes increase, operating on a cloud provider’s infrastructure can be attenuated and cost advantage maintained by adopting a mixed-use strategy, in which some of the applications and services are brought in-house and others continue to be hosted in the cloud.

Living in the Cloud is the future of computer technology, with a lucrative, revenue potential for savvy, forward-thinking companies who plan to keep ahead of their competitors.

Increasingly, businesses and organisations are being warned that if they do not recognise and embrace the evolving online landscape where “cloud computing” will ultimately reign, they would fail to keep up and be left behind.

The Cloud, unlike traditional computing, is free from the confines of desktop-based software. Computer terminals run and store programmes from a third-party server connected to the web, eliminating the risk of a total loss of data if the system crashes.

No longer requiring expensive in house software, a DesktopLive set up of a server automatically allocated web based applications, and the benefits of a significantly reduced running cost with full IT Support, should be immediately apparent to end user clients.

According to a recent study at Merrill Lynch, the global financial management and advisory analysts, cloud technology is “seen as a $160-billion addressable market opportunity, including $95-billion in business and productivity applications, and another $65-billion in online advertising”.

Merrill Lynch also suggest that roughly $2-billion of software segment will switch over to ‘OnDemand’ programmes, adding that Cloud equivalents exist today for most business and personal productivity applications, with e-mail and word processing now equivalent to traditional software.

For some companies, migrating from the old world to the new world, would entail adopting an entirely different way to think about computing functions and the ‘letting go’ of habitual attitudes to onsite retention of company data, applications and servers.

The rapidity of today’s responsive communication environment and the critical need to have joined up information access is inevitably reaching tipping point. Organisations struggling with an increasing burden of data management, storage and access will concede at least, they might finally have to address their concerns of how they can communicate b2b and b2c more effectively and efficiently.

Microsoft has changed the rules.

As I am sure you know it used to be the case that licensing for Microsoft Exchange was based on the number of outgoing mail boxes you had within the business.  What I mean by this is that firstname.surname@managednetworks.co.uk needs an Exchange CAL as does info@managednetworks.co.uk – if you want to send emails from info@.

For Microsoft Exchange 2010 this is no longer the case.

If you use a lot of generic email addresses and wish to reply from them, you only need to provide CALs for the number of users you have.  This does not mean that the 3^rd party software vendors have followed the same model. Sophos for instance is licenced on the basis of highest number of user or workstation/server or email user i.e. 40 users, 42 workstations, 4 servers with 75 outbound email addresses will need a 75 user license to be compliant. GFi works exclusively on unique out bound email addresses, the preceding example would require 75 licenses.

Another change is that Microsoft Exchange 2010 no longer provides an Outlook Licence as part of the User CAL.  You will need to buy an extra license, either separately or as part of Microsoft Office.

I hope this helps your licensing calculations

Cloud computing is increasingly being considered as the way forward to simplify a company’s spreading virtual and physical infrastructures, and uptake continues to gain momentum. For many businesses, from SMEs to larger organisations offering particular types of services and products, the workplace is now predominantly virtual, and their workforce geographically dispersed.

Obviating the need for onsite servers, the embrace of the scalable DesktopLive concept, and the definitive benefits of remote data access and sharing, is still to be fully accepted in both the private and public domains. Lingering apprehension still prevents a sea change of attitude over issues like data privacy and security, and ability to integrate with a company’s existing set up.

A recent report from the International Data Corporation (IDC), estimates that the influence of public cloud computing would increase growth of server hardware revenues in the next 4 years. However, as public clouds were less likely to be broadly adopted than private clouds, growth would be even bigger for the larger, private cloud market.

The public cloud is essentially defined as outsourcing data centre storage to external servers and applications, which can then be accessed remotely from a PC. The key selling point of this model is the cost saving on hardware, and active IT support and maintenance .

The private cloud is more likely to be adopted by those companies, especially larger institutions like banks or the public sector, who are concerned with the security of releasing highly confidential information from behind their own firewall.

This model keeps all physical hardware within a company’s own location, meaning the day to day running of the systems, maintenance, and – most importantly – security aspects, are run in house.

However, by implementing extra software to optimise the hardware to its fullest potential, and ease the transactions of data and information between servers, both in one office or to other geographic locations, a highly virtualised environment can be achieved.
