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... (more)
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.
Sematext was one of the very first companies that offered to help us by
offering their Docker monitoring and logging solution. They became the
official monitoring system for Swarm3K. Stefan, Otis and their team provided
wonderful support for us from the very beginning.

To my knowledge, Sematext is one and the only Docker monitoring company which
allow to deploy the monitoring agents as the global Docker service at the
moment. This deployment model provides for a greatly simplified the

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:
Your adrenaline kicks up…
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)

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.
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.

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
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... (more)

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

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
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.
