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.
Before becoming a developer, I was in the high school band. I played several brass instruments - including French horn and cornet - as well as keyboards in the jazz stage band. A musician and a nerd, what can I say? I even dabbled in writing music for the band. Okay, mostly I wrote arrangements of pop music, so the band could keep the crowd entertained during Friday night football games. What struck me then was that, to write parts for all the instruments - brass, woodwind, percussion, even k...

Sharding has become a popular means of achieving scalability in application architectures in which read/write data separation is not only possible, but desirable to achieve new heights of concurrency. The premise is that by splitting up read and write duties, it is possible to get better overall performance at the cost of a slight delay in consistency. That is, it takes a bit of time to replicate changes initiated by a "write" to the read-only master database. It's eventually consistent, and it'...

No matter how well-built your applications are, countless issues can cause performance problems, putting the platforms they are running on under scrutiny. If you've moved to Node.js to power your applications, you may be at risk of these issues calling your choice into question. How do you identify vulnerabilities and mitigate risk to take the focus off troubleshooting the technology and back where it belongs, on innovation? There is no doubt that Node.js is one of today's leading platforms of ...

Adding public cloud resources to an existing application can be a daunting process. The tools that you currently use to manage the software and hardware outside the cloud aren’t always the best tools to efficiently grow into the cloud. All of the major configuration management tools have cloud orchestration plugins that can be leveraged, but there are also cloud-native tools that can dramatically improve the efficiency of managing your application lifecycle. In his session at 18th Cloud Expo, ...

Keeping pace with advancements in software delivery processes and tooling is taxing even for the most proficient organizations. Point tools, platforms, open source and the increasing adoption of private and public cloud services requires strong engineering rigor – all in the face of developer demands to use the tools of choice. As Agile has settled in as a mainstream practice, now DevOps has emerged as the next wave to improve software delivery speed and output. To make DevOps work, organization...

There's a lot of things we do to improve the performance of web and mobile applications. We use caching. We use compression. We offload security (SSL and TLS) to a proxy with greater compute capacity. We apply image optimization and minification to content. We do all that because performance is king. Failure to perform can be, for many businesses, equivalent to an outage with increased abandonment rates and angry customers taking to the Internet to express their extreme displeasure.

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

Let's just nip the conflation of these terms in the bud, shall we?
"MIcro" is big these days. Both microservices and microsegmentation are having and will continue to have an impact on data center architecture, but not necessarily for the same reasons. There's a growing trend in which folks - particularly those with a network background - conflate the two and use them to mean the same thing.
They are not.
One is about the application. The other, the network. T...

This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you...
