The ongoing digital transformation continues to generate a steady demand for workers with increasingly sophisticated digital skills. This process is multi-dimensional and workers with these highly specialized skills are very much sought after. The European Union Commissionestimates that there could be a shortage of around 800,000 information and communications technology (ICT) specialists in the EU by 2020. A third dimension is the fact that there is a growing need to reskill the existing workforce, especially in light of the Fourth Industrial Revolution and the incorporation of the Internet of Things (IoT) and cyber-physical systems into the industrial production process. The “smart factory” also opens up new possibilities of individualized and efficient customer care and smoother communication with suppliers in the supply chain logistics. This is based on cloud-ba...

Docker Swarm Lessons from Swarm3K

This is a guest post by Prof. Chanwit Kaewkasi, Docker Captain who organized Swarm3K – the largest Docker Swarm cluster to date. Swarm3K Review Swarm3K was the second collaborative project trying to form a very large Docker cluster with the Swarm mode. It happened on 28th October 2016 with more than 50 individuals and companies joining this project.

AppSphere 2016 kicks off in Las Vegas

Life in the digital transformation Maybe you don’t gamble, but imagine you’re in a major Las Vegas casino feeding some dollars into a slot machine. The reels are spinning. They begin to stop one at a time: Triple Diamond… Triple Diamond… Your adrenaline kicks up… Triple Diamond! Then suddenly, every slot machine in the place goes dark. The bleeps and rings are replaced by groans and some scattered disbelieving laughter. And then, the murmur of conversation as patrons begin to talk about the odd and frustrating situation they’re in. You hear some raised voices that match your anger as some, like you, were in the middle of a payout. And, of course, out come the mobiles. Within minutes, their experience becomes the world’s experience. And if you think you’re out some money that should be coming your way, imagine you’re the owner of that casino. Thousands of dollars co... (more)

An Introduction to the Personal Cloud

Think of an austere, windowless room filled with massive metallic machines. All are hooked together with multi-colored wires and covered in lights that blink at random. What metaphor would you use to describe that? Odds are, you wouldn’t say, “A cloud.” In reality, “the cloud” doesn’t refer to the data center itself but to how companies use the resources of the data center to deliver massive compute power as a service over the Internet. Here’s a review of where the cloud came from, its role in DevOps and new trends in cloud development that could unleash massive market disruptions as soon as 2017. Cloud Origins Many organizations have used the term “cloud computing,” or the engineering symbol of a cloud on schematic diagrams, to represent an unspecified pathway of various server resources connected over the Internet. As a business ... (more)

What’s in an Environment? How much do they cost?

When I talk to people about environment management I’m surprised by the number of people who don’t understand how much they cost.  In a large organization it isn’t immediately obvious just how much a particular environment costs.  It isn’t like people announce how much a VM costs every time someone spins one up to support a QA test. People using these environments: the developers developing code and the QA testers checking features are almost never thinking about the fact that a large staging environment has a hefty price tag. If you are an environment manager dealing with a 3rd party cloud provider such as Amazon or Rackspace the costs are known, but at a large organization with a private cloud you are often dealing with a central IT department that manages infrastructure and costs are captured as a chargeback to a business unit.  In the later scenario it can be a...

Open Source Cloud Computing Testing Tools

Testing tools and frameworks are infinitely useful when planning cloud architecture for many reasons. “The confidence of a well-tested codebase brings the ability to deploy quickly, and often. Testing infrastructure assures that incremental changes to the codebase do not affect the overall application performance,” said Omid Rahmat, president, Burnside Digital. One of the Rahmat’s favorite testing tools is rspec, used for ruby applications. Rahmat said it takes a "behavior-driven" approach to testing. “We follow the best practices of writing tests that explain what our code should do before writing it. This gives us a clear path to follow to implement solutions with great confidence and far fewer defects. Having that test and seeing it pass lets us know that we have written features to specification.” Other popular testing tools include: SoapUI. According to Soap... (more)

Personal Cloud Usage Influences Company Adoption: CDW

As you go, so goes your company. At least in terms of which cloud apps you use that find their way into the workplace. Showing that work imitates life, a CDW report surveyed 1,242 IT professionals and found that a major driver of corporate cloud adoption is users' experiences of consumer services. Nearly three quarters of respondents (73%) claimed that, in their company, employees' use of personal cloud apps has "significantly influenced" the decision to move wholesale to the cloud. Similarly, just over three in five (61%) cloud-using organizations agreed that employee personal devices have culminated in a faster move to the cloud, according to an article on CloudComputingNews.net. It's also the case with IT professionals - two-thirds agreed that their personal use of cloud has influenced the company in terms of adoption. Another aspect of the CDW research was a de... (more)
