In case you have missed the first half of my insane tour through Europe, I have stayed in more cities in the past month than most people visit in a decade. Staring in Munich, I rented a motorcycle, loaded up a few hundred pounds of video and demo equipment, and have been riding around Europe to celebrate the launch of the Java 8 release with an itinerary including 4 conferences and 30 JUGs!

In his session at 14th Cloud Expo, David Holmes, Vice President at OutSystems, will demonstrate the immense power that lives at the intersection of mobile apps and cloud application platforms. Attendees will participate in a live demonstration – an enterprise mobile app will be built and changed before their eyes – on their own devices.
David Holmes brings over 20 years of high-tech marketing leadership to OutSystems. Prior to joining OutSystems, he was VP of Global Marketing for Damballa, a leading provider of network security solutions. Previously, he was SVP of Global Marketing for Jacada where his branding and positioning expertise helped drive the company from start-up days to a $55 million initial public offering on Nasdaq.
We all want usability, that’s a given right? We exist in an enterprise world, but we want to behave as naturally as possible with all of the technologies and devices that we come into contact with every day.
The co-called ‘consumerization of information technology’ suggests that we as users have adopted powerful devices for our home and personal use. These devices will in many respects out-perform those devices that we might be using or have used in the workplace.
From data center to cloud to the network. In his session at 3rd SDDC Expo, Raul Martynek, CEO of Net Access, will identify the challenges facing both data center providers and enterprise IT as they relate to cross-platform automation. He will then provide insight into designing, building, securing and managing the technology as an integrated service offering.
Topics covered include:
High-density data center design
Network (and SDN) integration and automation
Cloud (and hosting) infrastructure considerations
Monitoring and security
Self-service and automation
I was asked by Mr. Peter Hastings (NH DoIT Commissioner) about my understanding and knowledge of "End to End Solutions". I have witnessed these solutions before but I wanted to find a good definition. So, I began my research and found this definition: One supplier or one company that can provide all of your hardware and software needs in a suite of tools that meets all of the customers requirements and no other suppliers need to be involved. I think this is a good one and makes sense to me.
I'm sure there are many other definitions that exist and this is simplistic in nature but I see this as a baseline definition. One could certainly branch off of this definition to encompass a variety of explanations but let’s stick with this one for this article.
This idea has been around for sometime now and slowly but surely as the years go on it seems to go away and pop up and go away and pop up, etc... I have been watching and observing for a long time as well and witnessed the process and implementation of these suites over the years and have developed my own opinions about all encompassing tools. So, this has come up before

The is a LOT of hype around the Internet of Things (IoT). Lots of
vendors selling proprietary solutions that have very little to do with
the Internet of Things but everything to do with locking customers into a
single solution. If we are going to have a truly open Internet of
Things, the solutions will need to be interoperable.
MongoDB is evolving rapidly. The 2.2 version introduced the aggregation framework as an alternative to the Map-Reduce query model. Generating aggregated reports is a recurrent requirement for enterprise systems and MongoDB shines in this regard.

Nothing is perfect in the world, except a football skill of Leo Messi. Yeah, maybe not always but in most cases it’s impossible to create an ideal process. But I’m not scared to talk about my vision of a perfect test automation in a context of a software development. My work experience gives me confidence in this question. So I’m starting!For whom this article is writtenBefore I have...
What started out three years ago as in a form of a single ANT file has grown into literally a hundred of build tasks taking more than eight hours to complete from start to finish on sequential run. In this post we describe some of the tools and techniques we have applied into our build infrastructure.We have had four different goals in mind when creating our build:

The rabbit is out of the hat: I'm indeed working on a new book. It's called "RabbitMQ Essentials"
and is published by PackT Publishing. Yes, you're reading right, after
Mule, it's now RabbitMQ's turn! Clearly, I'm specializing in writing
about animal-named technologies.

Today I saw two things I cannot recall having seen before:
This article covers a WSDL for a web service in which the target namespace and the service address were identical, and put a Mule web service proxy in front of the web service exposing the WSDL, not only the port address of the web service endpoint were rewritten, but also...

When you are in the log management
business, who manages your logs? Well, you do, of course. The proverbs
of old, though, tell you this can sometimes be a very bad idea. In the
Irish language the saying is:
“Ba mhinic droch-éadach ar tháilliúr ‘s droch-bhróg ar ghréasaidh.”
Or, in English, “Often the tailor has bad clothes and the cobbler has
bad shoes.” The Scots’...
