What is Cloud Computing?

By Andrew Gregson, Novosco Creative Technology Director

Cloud Computing has long been a buzz word in the IT industry. Everyone is jumping on the cloud trend, but what does it really mean for businesses? What options are available today and what are the customer benefits of adopting a cloud IT infrastructure?

It is not surprising that companies find the cloud computing model confusing or fuzzy. Among the jargon however lies a fundamental change in the way IT operates. It’s about looking at ongoing IT costs per user and having a trusted ‘cloud provider’ to worry which technologies/hardware to host your infrastructure on. With cloud providers hosting the infrastructure, companies simply pay a fee per user/per month, with no capital expenditure (CAPEX) to spend. Only when businesses (large & small) start to actively embrace this model, will they realise both the immediate and future benefits of cloud computing.

Novosco’s definition of cloud computing…

Cloud computing provides computing resources on demand and leaves the worry of IT hardware/infrastructure to cloud providers.  Instead of companies buying traditional hardware, they simply avail of a hosted hardware/software platform and rent ‘IT as a service’; taking the form of hosted servers, hosted software applications and hosted online backup.

Affordable Videoconferencing using CloudStream Net

Videoconferencing uses telecommunications of audio and video to bring people at different sites together for a meeting.  Videoconferencing has traditionally been an expensive communications luxury for companies.  Its availability has been around for years, but with its high implementation cost and associated low quality & video streaming problems, organisations have weighted the opportunity cost of its purchase as high.  These problems have indeed prevented videoconferencing from becoming a standard form of communication within companies. 

Novosco CloudStream Net makes affordable Videoconferencing a reality.  All customers need is:

1) Any PC & webcam – One per site.  (Apple iMac is a popular choice as the camera resides in the screen.)   
2) To use free software or web plugins such as  Skype, ichat, google talk
3) Novosco CloudStream Net – Cloud Network Service (charged at a monthly rate)

HOW?

CloudStream Net is a cost-effective network service that among other benefits increases broadband speed and upload/download speeds.  This allows phenomenal improvements in VoIP and video conferencing quality, but without huge costs.  Without the frustrations of poor video quality, companies can audio and visually communicate as well as quickly share documents and computer-displayed information.   With improved broadband speed, even if miles from the local exchange, communicating with remote offices through videoconferencing is now a refreshing reality with CloudStream Net. With a reliable, fast line using CloudStream Net, customers can get the most out of tools such iMacs and ichat/Skype.

Top 10 Money Saving Tips in the Public Sector

1. Virtualise Your Servers

This is arguably the lowest hanging fruit, in terms of a quick return on investment and tangible cost reduction. The savings to be made, through reduction of power and support can be easily quantified and a business case can be quickly written to justify the initial spend. In terms of how many physical servers can be virtualised onto a single host, a 10:1 ratio is the industry rule of thumb at the moment e.g. a reduction of 100 servers down to 10 hosts.  Organisations holding back on virtualisation because they perceive it as risky should consider that server virtualisation will in most cases, make their infrastructure more resilient than before.  Platforms such as messaging, database and general application delivery are now being virtualised whereas perhaps a year ago, many people were holding back. Quite simply, the technology is mainstream and virtualisation is now the de facto standard for server infrastructure.

2. Virtualise Your Desktops

Many government organisations already run virtual desktops in one shape or another (e.g. Microsoft Terminal Services or Citrix XenApp).  However the paradigm for virtual desktops has shifted. The ability to provide the user with the horsepower, customisation and flexibility which they are used to with a physical desktop, is now available from a number of vendors. As with server virtualisation, the benefits are primarily around cost savings in terms of power usage and user management (albeit on a larger scale, due to the higher number of devices) but this solution can provide many spinoff benefits such as universal remote access. With new directives being issued around disaster recovery and the ability to provide services in the case of a national emergency, this can be of major significance.

3. Virtualise Your Applications

As distinct from virtual desktops, the challenge of delivering applications can be a time consuming and costly business. By virtualising the application delivery process, significant economies of scale can be realised.  Irrespective of whether you virtualise the desktop Operating System, being able to create an “application jukebox” reduces the cost of deployment, upgrade and ongoing support. Virtualised applications give the administrator the choice of whether to install, cache, publish or stream. When combined with virtualisation of the other layers of the stack, it all adds up to major cost savings.

4. Reduce Your Communications Spend

Many organisations are in the process of moving to VoIP which has clearly defined cost saving benefits. However, the amount being paid for traditional data connectivity is still a significant part of the overall IT budget. By analysing the true nature of the traffic traversing your network, it is good practice to introduce optimisation solutions which reduce the amount of physical traffic being moved. This invariably leads to a reduction of your telecommunications bills. When combined with certain thin client solutions, telecommunications traffic can be further reduced. Bear in mind that these savings will very much depend however on the nature of your applications and existing connections.

5. Reduce Your Storage Spend

Running out of disk space is an ever increasing problem. The advent of collaboration and document management plus increasing use of messaging and web browsing means that data is growing exponentially. The default reaction to a sudden capacity problem is to buy more disks.  People do not often have the luxury of figuring out a storage strategy in such an instance. This means that organisations can be left with large amount of expensive ‘near line’ storage for all of their data, even for data which is rarely accessed, if ever. By taking the time to understand the true nature of your organisation’s data, a new storage architecture can be created, with the dual purpose of being more efficient while costing you less money. Novosco work with EMC to carry out in-depth assessments of data growth in the public sector. Using advanced data analysis tools, Novosco and EMC can help you to more accurately measure how and why your data is growing the way it is.

6) Outsource Some IT Functions

The ‘O’ word can be a scary one, especially in today’s economic environment. However, it should be viewed as an opportunity to be smarter about how we can capitalise on the existing skills we have. For each aspect of IT, the lower the skill level, the more it should be considered a candidate for outsourcing. Outsourcing allows you to upskill existing staff to deliver more value to the organisation. Areas such as hardware maintenance or printer management have traditionally been outsourced. Other parts of the infrastructure which were previously considered as skills-intensive are now viewed within the industry as as a commodity, skills-wise. One example is messaging: the day-to-day administration of email is a job which adds very little value to the organisation but costs quite a lot in comparison. By outsourcing that function, savings can be made across a range of areas from telecommunications to licensing and from power to administration costs. The flexibility now available in terms of outsourcing is unprecedented. Everything from on-site resources to hosting virtual systems on a per usage basis means that your organisation can pick the level of outsourcing which makes the most sense.  Other examples which can result in significant savings, are the outsourcing of your organisation’s disaster recovery and backup solutions.

7) Consolidate Your IT Infrastructure

Organisations with many remote offices will have experienced the organic growth of equipment, data and support requirements over a passage of time.  The need for local infrastructure in many cases is not always required. Many organisations are looking at how they can centralise critical IT functions into one location. The benefits are not just around cost savings (due to the reduction of physical systems) but also around security, compliancy, accountability and disaster recovery.

8) Explore Green IT

The government as a whole is committed to the green agenda and there are many ways in which IT can make a difference. Green IT encompasses many things but one of its fundamental directives is that it can save you money. Lower the energy used by your IT equipment and you will very quickly recoup any expenditure or effort involved. Some simple steps can quickly reduce your power footprint.  Implement the power saving functions native to your PC’s operating systems, replace ‘fat PC’s’ with thin clients (as less moving parts require less power), and consolidate your servers to dramatically reduce both their power and cooling requirements. You can even go as far as automating the powering down of server workloads during out of hours operations. These are just some of the ways that you can reduce your carbon footprint, save your organisation money and do a little to help the environment.

9) Increase Productivity

Productivity in the IT sense means having access to the information your workers need, when they need it. It is possible to implement extremely powerful information repositories and search tools ‘out of the box’ now, as key data is already stored inside indexable sources such as a directory structures, ODBC-compliant databases and/or messaging systems. It is incumbent on all government bodies to provide their users with the means to access the relevant information in a timely fashion and to ensure that this information is secure, accurate and relevant. If workers are productive it means that they are delivering more value to the organisation. At the launch of the late Paul Tansey’s report into Productivity in late 2007, the then Taoiseach Bertie Ahern commented: “The productivity debate and the need to have a productivity mindset and culture embedded in both public and private sector organisations is more important now than at any time in our recent economic history.”

10) Pick a Strategic Partner

Novosco has extensive experience working with public sector bodies to help them streamline services and cut costs. As Ireland’s leading virtualisation expert with the highest level of certification with Microsoft, VMware, Citrix and EMC, Novosco are well placed to independently advise our clients on the strategic direction of their IT infrastructure.

Reaction to MS08-067

Last week Microsoft published Security Bulletin MS08-067. This bulletin describes a vulnerability in the Windows server service, affecting Windows 2000, XP, Vista, 2003 and 2008.

Microsoft have also released a corresponding “out-of-band” (i.e., not contained in the monthly batch of updates) update in the shape of KB958644. The update is available from Microsoft Update.

Novosco are actively encouraging all of our customers to deploy the update as soon as possible (on all Windows hosts – clients and servers). You can do so by visiting the Microsoft Update website or by deploying with Windows Server Update Services or some other 3rd party deployment tool.

But why all the fuss? Well, this particular vulnerability is wormable – meaning that potentially (more on “potentially” later) the vulnerability can be exploited by a worm, i.e., self-replicating malicious code that seeks out vulnerable hosts and infects them from your laptop while you’re writing your blog post…

Talking about worms in this way takes me back to those bygone halcyon days when Windows anti-virus was “optional”, host based firewalls were unheard of and the only reason to use a firewall in the enterprise was to take advantage of its NAT capabilities and not fork out for expensive publicly routable IP addresses for your network. It was also the time before we had all deployed WSUS or some other automatic update solution. Right?

Wrong! Even though we now have written policies defining that laptops must have host-based firewalls and AV, and we have fancy UTM devices at the network perimeter, all too often we still have the problem that updates are being ignored. Consider this situation: a user goes home with their company laptop (which hasn’t been updated in the last 8 months) and browses the web for a while from their home internet connection. Because Internet Explorer hasn’t been patched they get burned by some exploit which drops a Trojan containing code which in turn exploits the MS08-067 vulnerability. The user didn’t really do anything wrong, wasn’t an local administrator and knows nothing of the infection. Next day they plug their laptop into the corporate network and while they’re at the coffee machine ten minutes later they see the IT admins running past on their way to the server room as the “whole network’s down!!!!”.

Update mangement would have saved that company on two counts – the first by patching the user’s laptop. If it wasn’t vulnerable the malicious code wouldn’t have got onto it in the first place. The second; even if the laptop hadn’t been patched (say the user was off work for a while and got infected anyway) the servers would have been patched and wouldn’t have been vulnerable so no downtime would have occurred.

That example’s a bit simplified, certainly a layered security solution of best practices, AV and UTM would have helped. But I think it serves to get the message across – the fuss surrounding this update is symptomatic of a bigger problem.

Now I put “potentially” in bold above for a reason – there is no worm exploiting this vulnerability (that we know of, yet). Right now, there is however a recognisable trojan which is being used in targeted attacks. And, there’s publicly available exploit code in the wild which means you can bet that VXers are beavering away trying to develop a suitable worm. So you have a choice – patch now or don’t. You can choose not to and give me the old excuses about the risks of deploying patches (breaking applications etc) but that’s why Microsoft genuinely recommend that you test their updates with your applications and if you’re really that worried you should seriously think about a test environment, but if (maybe when) the worm hits and you get burned I’ll try not to say “I told you so”.

Remember folks – “Proactive patching is better than reactive repair”.

A New World of Fault-tolerance

At VMworld 2008, VMware announced VMware FT, their solution for continuous availability (zero downtime on hardware component failures – different from HA. HA is a crash and reboot). This will stack up nicely against the likes of Marathon Technologies and Stratus who have been doing this for a while.  And since everyone and their granny are rolling out a VMware based infrastructure, they will be best positioned to take advantage of it.

Stratus is currently a hardware based solution and Marathon’s is software, running on Windows Server 2003. Both of these companies have enjoyed a certain level of exclusivity but that of course will not last. I have very little info on where Stratus is going other than it can run ESX on its FT kit. Marathon have embraced the Xen hypervisor and have jumped in bed with Citrix, helping Citrix initially provide a host based XenServer HA solution (on a per VM basis!), along with their on HA solution for XenServer adding component level HA. And eventually in Q1 2009, their XenServer based FT solution will be released.

What this means, is that we will still have a choice about which hypervisor to use across all availability levels: Marathon on XenServer and VMware.  This is good!

After reading a blog post from Marathon about VMware FT and some retort from a VMware supporter, I thought I’d throw in my 2p, as there appeared to be some problems with these arguments.

Firstly, the comparison is Marathon’s existing FT product that only runs on Windows against VMware’s that only runs on VMware’s hypervisor. This is a pointless comparison as they dont compare like for like and  VMware’s product has not been released and wont be until some time in 2009. It would be a much fairer comparison to pitch Marathon’s new XenServer based FT against VMware’s FT…when they both arrive.

Secondly, Marathon argued against the requirement for shared storage with the VMware FT solution and the VMware guy stated that where you’d want to use FT you’ll likely have a SAN in place anyway. I have a slight issue with this. Quite often, FT solutions are used for critical production lines, health systems and emergency services. These systems may not run anywhere near a SAN, nor require one. It would be a considerable expense to require a SAN just for a 2 node FT solution. Also consider the site that has two data centres connected via fiber. We have Marathon FT systems running like this, which would allow for the likes of a site failure. This kind of setup requires that the writes are done to each system and that shared storage just doesn’t work in all cases.

Judging by the review of the FT session at VMworld by Scott Lowe, VMware may change their minds about the need for shared storage for FT. I hope so.  I think it’s great that VMware is getting into this game.  We have a lot of VMware sites that would be reluctant to add another virtualisation platform into the mix at this time. Being the pioneers and market leaders of server virtualisation gives them a big advantage. It widens their scope and will certainly provide decent competition for Citrix and Marathon. But, Marathon have been in the FT game for a long time too and know the problems and limitations that can be encountered in FT land. I wouldn’t underestimate them either.
