Nothing is more enlightening for a technologist than to observe development in progress. We're faced constantly with a bewildering array of choices and tools. We see specifications on paper that then become something completely different when we actually get to see them implemented in actual software that we then configure to meet our needs, or at least we hope.
I've been spending some time working with a team doing an SOA proof-of-concept test and it's reminded me of what an open book the world of SOA is, and how few pages have really been written in it. The migration of ideas to specifications, and then their transformation within software is a strange process.
Given that SOA has so many optional parts, it's not hard to understand how difficult it is for a vendor to put together a product that actually guides developers in the development process. In what may be the biggest irony of SOA, the technology that we use to enable interoperability is really a set of standalone software, distinct and separate from one another.
If you think about it, there is a logical progression of development for SOA, but because so much of SOA is about enabling communications with existing software rather than creating new services from scratch, there is no one typical development path. This is unfortunate, because the current situation is very similar to a least-common denominator approach, one where each aspect of development is distinct and isolated. You have one console for creating UDDI registry entries, another tool for creating WSDL and other documents, yet another tool for the actual coding of a service, and still another, different place for defining security entitlements. None of which are aware of one another. This makes development a fragmented, disjointed process.
Some may argue that it has to be this way for a toolset to support the broadest range of capabilities. I would agree, but I also think it's possible to create an SOA-focused development tool in the same way that folks like Borland created a Java editor that understood the environments in which it was used. In the same way that code editors today can understand the differences between BEA WebLogic and IBM WebSphere, there is a need for a development environment that understands the various standards as well as the concrete implementations of those standards and how to interface with them to make a development process seamless.
I am well aware this is not as trivial as it sounds. Just keeping an environment in synch with the various levels of specifications is not trivial. Supporting the latest is never enough - think about what would happen if the actual deployment environment is behind in revisions and needs a previous version. Now add to that differing implementations of standards by various vendors and you can begin to imagine the scope and depth of this problem. A good number of vendors have shied away from even contemplating a solution to the issue, preferring to believe there is no solution.
That's a problem, and an opportunity. SOA is too complex to be implemented piecemeal by cobbling together a set of tools. There is a strong need for a product to manage the complexity and variety of the process in a structured fashion. While XML editors such as XML Spy are very good at what they do, what's really needed is a more structured approach to creating services that removes the need to edit XML at all in favor of a more integrated approach that allows the developer to see into the whole process. Simple services are easy enough, but once we start to build complex, composite services that use things like WS Transactions or WS Orchestration, there needs to be a holistic view of the entire process, including the documents and descriptions that go along with service deployment.
This issue focuses on development tools, techniques and practices. We'll show you how to do SOA now, and let you think about how it should be done better in the future.

If you are new to Python, you might be confused about the different versions that are available. Although Python 3 is the latest generation of the language, many programmers still use Python 2.7, the final update to Python 2, which was released in 2010. There is currently no clear-cut answer to the question of which version of Python you should use; the decision depends on what you want to achieve. While Python 3 is clearly the future of the language, some programmers choose to remain with Py...

Opinions on how best to package and deliver applications are legion and, like many other aspects of the software world, are subject to recurring trend cycles. On the server-side, the current favorite is container delivery: a “full stack” approach in which your application and everything it needs to run are specified in a container definition. That definition is then “compiled” down to a container image and deployed by retrieving the image and passing it to a container runtime to create a running...

Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud wit...

As the world moves towards more DevOps and microservices, application deployment to the cloud ought to become a lot simpler. The microservices architecture, which is the basis of many new age distributed systems such as OpenStack, NetFlix and so on, is at the heart of Cloud Foundry - a complete developer-oriented Platform as a Service (PaaS) that is IaaS agnostic and supports vCloud, OpenStack and AWS. In his session at 17th Cloud Expo, Raghavan "Rags" Srinivas, an Architect/Developer Evangeli...

Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ab...

Application availability is not just the measure of “being up”. Many apps can claim that status. Technically they are running and responding to requests, but at a rate which users would certainly interpret as being down. That’s because excessive load times can (and will be) interpreted as “not available.” That’s why it’s important to view ensuring application availability as requiring attention to all its composite parts: scalability, performance, and security.

There once was a time when testers operated on their own, in isolation. They’d huddle as a group around the harsh glow of dozens of CRT monitors, clicking through GUIs and recording results. Anxiously, they’d wait for the developers in the other room to fix the bugs they found, yet they’d frequently leave the office disappointed as issues were filed away as non-critical. These teams would rarely interact, save for those scarce moments when a coder would wander in needing to reproduce a particula...

What Is Emergent About Emergent Architecture? By @TheEbizWizard | @DevOpsSummit #DevOps #BigData #API
All we need to do is have our teams self-organize, and behold! Emergent design and/or architecture springs up out of the nothingness! If only it were that easy, right? I follow in the footsteps of so many people who have long wondered at the meanings of such simple words, as though they were dogma from on high. Emerge? Self-organizing? Profound, to be sure. But what do we really make of this sentence?

As we increasingly rely on technology to improve the quality and efficiency of our personal and professional lives, software has become the key business differentiator. Organizations must release software faster, as well as ensure the safety, security, and reliability of their applications. The option to make trade-offs between time and quality no longer exists—software teams must deliver quality and speed. To meet these expectations, businesses have shifted from more traditional approaches of d...

Information overload has infiltrated our lives. From the amount of news available and at our fingertips 24/7, to the endless choices we have when making a simple purchase, to the quantity of emails we receive on a given day, it’s increasingly difficult to sift out the details that really matter. When you envision your cloud monitoring system, the same thinking applies. We receive a lot of useless data that gets fed into the system, and the reality is no one in IT or DevOps has the time to manu...

Last month, my partners in crime – Carmen DeArdo from Nationwide, Lee Reid, my colleague from IBM and I wrote a 3-part series of blog posts on DevOps.com. We titled our posts the Simple Math, Calculus and Art of DevOps. I would venture to say these are must-reads for any organization adopting DevOps. We examined all three ascpects – the Cultural, Automation and Process improvement side of DevOps. One of the key underlying themes of the three posts was the need for Cultural change – things like t...

I’ve been thinking a bit about microservices (μServices) recently. My immediate reaction is to think: “Isn’t this just yet another new term for the same stuff, Web Services->SOA->APIs->Microservices?” Followed shortly by the thought, “well yes it is, but there are some important differences/distinguishing factors.” Microservices is an evolutionary paradigm born out of the need for simplicity (i.e., get away from the ESB) and alignment with agile (think DevOps) and scalable (think Containerizati...
