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.”
Android Go puts reliable smartphones in budget pockets
Nokia, Vodacom and Huawei have all launched entry-level smartphones running the Android Go edition, and all deliver a smooth experience, writes BRYAN TURNER.
Three new and notable Android Go smartphones have recently hit the market, namely the Nokia 1, the Vodafone Smart Kicka 4 and the Huawei Y3 (2018). These phones run one of the most basic versions of Android while still delivering a fairly smooth user experience.
Historically, consumers purchasing smartphones in the budget bracket would have a hit-and-miss experience with processing speed, smoothness of user interface, and app stability. The Google-supported Android Go edition operating system optimises the user experience by stripping out non-important visual effects to speed up the phone. Thish allows for more memory to be used by apps.
Google also ensures that all smartphones running Android Go will receive feature and security updates as they are released by Google. This is a major selling point for these smartphones, as users of this smartphone will always be running the latest software, with virtually no manufacturer bloatware.
Vodafone Smart Kicka 4
At the lowest entry-level, the Vodafone Smart Kicka 4 performs well as a communicator for emails and WhatsApp messages. The 4” screen represents a step up for entry-level Android phones, which were previously standardised at 3.5”.
The display is bright and very responsive, while the limited screen real estate leaves the navigation keys off the screen as touch buttons. It uses 3G connectivity, which might seem like an outdated technology, but is good enough to stream SD videos and music. Vodacom has also thrown in some data gifts if the smartphone is activated before the end of September 2018.
Its camera functionalities might be a slight let down for the aspirant Instagrammer, with a 2MP rear flash camera and a 0.3MP selfie snapper. Speed wise, the keyboard pops up quickly, which is a huge improvement from the Smart Kicka 3. However, this phone will not play well with graphics-intensive games.
Next up is the Nokia 1, which adds a much better 5MP camera, improved battery life and a bigger 4.5” screen. It supports LTE, which allows this smartphone to download and upload at the speed of flagships. It also sports the Nokia brand name, which many consumers trust.
Although the front camera is 2MP, the quality is extremely grainy, even with good lighting. This disqualifies this smartphone for the social media selfie snapper, but the 5MP rear camera will work for the landscape and portrait photographer.
The screen also redeems this smartphone, providing a display which represents colours truly and has great viewing angles. Xpress-on back covers allows the use of interchangeable, multi-coloured back covers, which has proven to be a successful sales point for mid-range smartphones in the past.
Huawei Y3 (2018)
The most capable of the Android Go edition competitors, the Huawei Y3 (2018) packs an even bigger screen at 5”, as well as an improved 8MP rear camera and HD video recording. The screen is the brightest and most vibrant of the three smartphones, but seems to be calibrated to show colours a little more saturated than they actually are.
Nevertheless, the camera outperforms the other smartphones with good colour replication and great selfie capabilities via the 2MP front camera – far superior to the Nokia 1 despite the same spec. LTE also comes standard with this smartphone and Vodacom throws in 4G/LTE data goodies until the end of September 2018. The battery, however, is not removable and may only be replaced by a warranty technician.
Comparing the 3
All three smartphones have removable back covers, which provide access to the battery, SIM card and SD card slots. The smartphones have Micro USB ports on the bottom with headphone jacks on the top. The built-in speakers all performed well, with the Y3 (2018) housing an exceptionally loud built-in speaker.
Although all at different price points, all three phones remain similar in performance and speed. The differentiators are apparent in the components, like camera quality and screen quality. It would be fair to rank the quality of the camera and battery life by respective market prices. The Vodafone Smart Kicka 4 performed well, for its R399 retail price. The Nokia 1, on the other hand, lags quite a bit in features when compared to the Huawei Y3 (2018), bwith oth retailing at R999.
SA gets digital archive
As the world entered the centenary of Nelson Mandela’s birth on Mandela Day, 18 July 2018, South Africa celebrated the launch of a digital living archive.
The southafrica.co.za site carries content about the country’s collective heritage in South Africa’s eleven official languages.
Designed as a nation building, educational and brand promotion web based tool, the free-to-view platform features award-winning photographic and written content by leading South African photographers, authors, academics and photojournalists.
The emphasis is on quality, credible, factual content that celebrates a collective heritage in terms of the following: Cultural Heritage; Natural Heritage; Education; History; Agriculture; Industry; Mining; and Travel.
At the same time as reflecting on the nation’s history, southafrica.co.za celebrates South Africa’s natural, cultural and economic assets so that the youth can learn about their nation in their home language.
Southafrica.co.za Founder and CEO Hans Gerrizen conceptualised southafrica.co.za as a means for youth and communities from outlying areas to benefit from the digital age in terms of the web tool’s empowering educational component.
“We can only stand to deepen our collective experience of democracy and become a more forward planning nation if we know facts about our nation’s past and present in everyone’s home language,” he says.
Southafrica.co.za, with sister company Siyabona Africa, is the organiser and sponsor of the Mandela: 100 Moments photographic exhibition that runs until 30 September at Cape Town’s V&A Waterfront-based Nelson Mandela Gateway to Robben Island. The 3-month exhibition, which runs daily from 08h00 until 15h00, is showcasing one hundred iconic Nelson Mandela images taken by veteran South African photojournalist and self-taught lensman Peter Magubane.
