A simple concept that could transform computing lies at the heart of the complex “new” tech discipline known as virtualisation, writes ARTHUR GOLDSTUCK.
Imagine that any smartphone you use can be turned into that of any brand you want. It may sound absurd in a world of deadly rivalry between Apple, Samsung and the like. But then imagine that any auomatic teller machine can instantly adopt the brand of your bank the moment you slip in your ATM card. Suddenly, that doesn’t sound so absurd. In fact, the possibility is closer than we may think.
It is made possible by a relatively new and complex information technology discipline called virtualsation, which allows for “virtual machines” to be created in data centres, on central computers called servers. A server can house any number of these virtual machines, which are tied to specific user identities. Log in with the appropriate details, and your personalised machine appears, with very specific applications and content specific to your role in an organisation.
The concept goes hand in hand with cloud computing, which allows applications, content and processes to be accessed from anywhere, on any device, at any time.
These concepts lay behind the creation of WMware, one of the world’s largest providers of cloud computing systems and until recently a subsidiary of storage leaders EMC. When computer giants Dell announced last year they would buy EMC for a record $67-billion, VMware was described as one of the jewels in the acquisition, and remained a separately listed company, with the new Dell Technologies as controlling shareholder.
It’s not hard to see why: the company keeps pushing the boundaries of what is possible in both cloud computing and virtualisation. At its recent VMworld conference in Barcelona, it unveiled new releases of most of its solutions that help companies streamline their IT operations. In combination, these solutions make up VMware’s Cross-Cloud Architecture, which enables companies to run, manage, connect, and secure their applications across any device or cloud service – now including market leaders Amazon and Microsoft – as if they are in their own customised environment.
Because virtual machines are dictated by software rather than hardware, and consumers and corporations alike are seeing their high-tech worlds defined by that software, it becomes easier to envisage smartphones, ATMs or any other hardware adapted to the purpose or preference of the moment. It makes sense, but it also requires a new mindset.
“We are now the psychologists of information, because we have to transform the way people think about techbology,” said Ian Jansen Van Rensburg, VMware Southern Africa’s senior manager for systems engineering, speaking at Vmworld. Ironically, however, South African techies are harder to convince than their counterparts in the rest of Africa.
“In South Africa, if you tell a storage guy his business is going to be a software business, and he’s just invested heavily in storage hardware, he’s probably not going down that route. Yet, everything is becoming software-defined, and people need to wrap their heads around this.”
The real irony is that, in the rest of Africa, far less has been invested in hardware, and the leap to software-defined data centres is far easier from a mindset point of view. Even more ironically, employees who once depended entirely on the IT department for assistance and resources are now bypassing IT administrators so that they can get what they need, when they need it.
For example, marketers who want to share large files online for an urgent project are no longer waiting for the techies sitting in the IT department to approve the budget or set up the appropriate “architecture” for file-sharing. Instead, they log on to the Dropbox online storage service, whip out their personal credit cards and pay for extra capacity. The cost is then charged to routine project expenses.
It may not make a big difference when it is a Dropbox here and a Google app there, but it adds up when such habits graduate to serious business applications. The combination costs so much, yet is not going through the IT budget, that the company has a distorted picture of what is being spent where.
VMware previously called this kind of spending “Shadow IT”, meaning it lurks unseen in the shadows of the IT budget. VMware CEO Pat Gelsinger, in his keynote address at the conference, used a new term, “self-starting IT”, referring to the ability of any tech-savvy staff members to become their own IT providers.
But help is at hand, says Matthew Kibby, VMware regional director for sub-Saharan Africa.
“Users were frustrated because the IT department couldn’t deliver an application to them fast enough. Eventually they got fed up and went to Amazon Web Services or Microsoft Azure and quickly got it off the cloud. VMware’s vision is is to give that control back to IT and say, you are now in control of your IT infrastructure, whether it’s being rolled out on a company laptop or a personal smartphone.
“We not only need to give them back that control, but do it along with the look and feel of being able to access any device from any application anywhere in the world. That’s exactly what the Cross-Cloud Architecture will achieve. We want to make the IT department or Chief Information Officer the new hero of the company again.”
Legion gets a pro makeover
Lenovo’s latest Legion gaming laptop, the Y530, pulls out all the stops to deliver a sleek looking computer at a lower price point, writes BRYAN TURNER
Gaming laptops have become synonymous with thick bodies, loud fans, and rainbow lights. Lenovo’s latest gaming laptop is here to change that.
The unit we reviewed housed an Intel Core i7-8750H, with an Nvidia GeForce GTX 1060 GPU. It featured dual storage, one bay fitted with a Samsung 256GB NVMe SSD and the other with a 1TB HDD.
The latest addition to the Legion lineup has become far more professional-looking, compared to the previous generation Y520. This trend is becoming more prevalent in the gaming laptop market and appeals to those who want to use a single device for work and play. Instead of sporting flashy colours, Lenovo has opted for an all-black computer body and a monochromatic, white light scheme.
The laptop features an all-metal body with sharp edges and comes in at just under 24mm thick. Lenovo opted to make the Y530’s screen lid a little shorter than the bottom half of the laptop, which allowed for more goodies to be packed in the unit while still keeping it thin. The lid of the laptop features Legion branding that’s subtly engraved in the metal and aligned to the side. It also features a white light in the O of Legion that glows when the computer is in use.
The extra bit of the laptop body facilitates better cooling. Lenovo has upgraded its Legion fan system from the previous generation. For passive cooling, a type of cooling that relies on the body’s build instead of the fans, it handles regular office use without starting up the fans. A gaming laptop with good passive cooling is rare to find and Lenovo has shown that it can be achieved with a good build.
The internal fans start when gaming, as one would expect. They are about as loud as other gaming laptops, but this won’t be a problem for gamers who use headsets.

Serious about security? Time to talk ISO 20000
By EDWARD CARBUTT, executive director at Marval Africa
The looming Protection of Personal Information (PoPI) Act in South Africa and the introduction of the General Data Protection Regulation (GDPR) in the European Union (EU) have brought information security to the fore for many organisations. This in addition to the ISO 27001 standard that needs to be adhered to in order to assist the protection of information has caused organisations to scramble and ensure their information security measures are in line with regulatory requirements.
However, few businesses know or realise that if they are already ISO 20000 certified and follow Information Technology Infrastructure Library’s (ITIL) best practices they are effectively positioning themselves with other regulatory standards such as ISO 27001. In doing so, organisations are able to decrease the effort and time taken to adhere to the policies of this security standard.
ISO 20000, ITSM and ITIL – Where does ISO 27001 fit in?
ISO 20000 is the international standard for IT service management (ITSM) and reflects a business’s ability to adhere to best practice guidelines contained within the ITIL frameworks.
ISO 20000 is process-based, it tackles many of the same topics as ISO 27001, such as incident management, problem management, change control and risk management. It’s therefore clear that if security forms part of ITSM’s outcomes, it should already be taken care of… So, why aren’t more businesses looking towards ISO 20000 to assist them in becoming ISO 27001 compliant?
The link to information security compliance
Information security management is a process that runs across the ITIL service life cycle interacting with all other processes in the framework. It is one of the key aspects of the ‘warranty of the service’, managed within the Service Level Agreement (SLA). The focus is ensuring that the quality of services produces the desired business value.
So, how are these standards different?
Even though ISO 20000 and ISO 27001 have many similarities and elements in common, there are still many differences. Organisations should take cognisance that ISO 20000 considers risk as one of the building elements of ITSM, but the standard is still service-based. Conversely, ISO 27001 is completely risk management-based and has risk management at its foundation whereas ISO 20000 encompasses much more
Why ISO 20000?
Organisations should ask themselves how they will derive value from ISO 20000. In Short, the ISO 20000 certification gives ITIL ‘teeth’. ITIL is not prescriptive, it is difficult to maintain momentum without adequate governance controls, however – ISO 20000 is. ITIL does not insist on continual service improvement – ISO 20000 does. In addition, ITIL does not insist on evidence to prove quality and progress – ISO 20000 does. ITIL is not being demanded by business – governance controls, auditability & agility are. This certification verifies an organisation’s ability to deliver ITSM within ITIL standards.
Ensuring ISO 20000 compliance provides peace of mind and shortens the journey to achieving other certifications, such as ISO 27001 compliance.
