New SOA modeling lesson

StorageSwiss George Crump Profile: StorageSwiss

A wise person once said that when you set out to do something, a good place to start is at the beginning.

Service-oriented architecture is no different. Often would be practitioners of SOA start in the middle, trying to integrate two different applications. In many cases that serves a tactical purpose, but that doesn’t address how to build a truly loosely coupled service. When you attempt to tackle that higher degree of difficulty, it all starts with modeling. You’d be looking at a haphazard design process and slew of problems in its wake if you failed to do a proper job of modeling your intended service.

With that in mind, we’ve added a modeling lesson to our Service Orientation for Architects School. It offers a Webcast with noted SOA guru Thomas Erl, covering SOA design considerations and best practices. Erl ties design principles to the core principles of service orientation and delves into the relationships between various design elements.

Victor Harrison of Computer Sciences Corp. sat down for a podcast, giving five insider tips for SOA modeling. The final leg of the lesson is a report detailing what constitutes the SOA lifecycle and what architectural challenges arise as a result of this new development lifecycle. Do NOT miss this report. It features advice from numerous leading analysts in the SOA space and lays out the lifecycle considerations that need to be understood at the start of any SOA project. It qualifies as an essential resource.

Podcast: The architecture of dynamic business applications

StorageSwiss George Crump Profile: StorageSwiss

The purpose of service-oriented architecture is to better marry IT to business initiatives … or at least that’s what SOA proponents keep telling us. Yet what are the technologies that enable that? John Rymer, vice president and principal analyst at Forrester Research Inc., has laid out what he calls B3, the essential ingredients for creating dynamic business applications. B3 includes business process management (BPM), business rules and business intelligence (BI).

He recently sat down for a podcast to describe the architectural underpinnings of dynamic business applications.


Topics covered include:

  • How SOA supports BPM efforts
  • What kind of data BI needs to provide in order to enable real-time business agility
  • What kinds of business rules need to be prioritized
  • How BPM, BI and business rules can work together
  • A sensible starting place for those looking to create dynamic business applications

Anyone interested in finding out more about this subject can get a free copy of Rymer’s report on Dynamic Business Applications from Forrester.

SOA security lesson

StorageSwiss George Crump Profile: StorageSwiss

In a recent survey, our readers reported security is the top organizational requirement for SOA. All of the agility in the world doesn’t matter if you can’t provide it in a secure fashion.

Yet traditional security isn’t sufficient to lock down a services infrastructure. Applications aren’t being housed on single servers in a static network. Changes in the application domain necessitate changes in the security domain and it is incumbent upon the application architects to plan for the different types of security that service-oriented architecture will require.

With that in mind, we’ve launched our new security lesson inside our Service Orientation for Architects School. It provides essential resources for architects looking to bake in the security that is essential for a proper SOA.

Burton Group’s Anne Thomas Manes offers up a Webcast on a holistic approach to SOA security. It deals with network options, end point intelligence and identity management practices. Steve Craggs of Lustratus Research identifies the top 5 SOA security traps in a podcast.

Craggs also has a written tip on the flexibility-security tradeoff.

It is no secret SOA is creating new vulnerabilities. It will be the users who educate themselves about how to protect against those new vulnerabilities, the ones who don’t expect someone else in the organization to find the holes, who make the most successful switch to service orientation.

New lesson on SOA messaging

StorageSwiss George Crump Profile: StorageSwiss

We spend a lot of time these days talking about governance and management when it comes to SOA. There’s a good reason to take that macro view, because far too many people get lost in the trees and fail to see the forest when it comes to service orientation. We are talking about enterprise architecture after all, so an enterprise-level view would be appropriate.

That said, you can put the perfect governance model in place and it won’t mean a thing if you don’t understand messaging. SOA requires a lot of integration work and integration, more often than not, requires messaging. With that in mind we created a messaging lesson in our Service Orientation for Architects School. It features a Webcast with WSO2’s Paul Fremantle on service-oriented messaging, in which he breaks down a slew of messaging alternatives, including JMS, HTTP, REST, SOAP, WS-Addressing, WS-ReliableMessaging and traditional message queues.

Yet more than that, Fremantle delves into messaging practices that will aid you on the SOA front. It’s one thing to boil up a big pot of integration spaghetti, quite another to architect a reliable messaging infrastructure. The lesson is focused on the latter.

Fremantle has also penned a tip on service mediation. As part of the Apache Synapse project, Fremantle has been instrumental in defining service mediation best practices.

The goal of mediation is to help create a flexible messaging backbone for your company. The tip covers a host of mediation techniques, including Web Caching, load balancing and message-based routing.

It’s an ideal chance to catch up on the architectural underpinnings of messaging as they apply to SOA. Even for those of you who feel fairly confident about your messaging skills, this lesson is sure to give you a few pointers to hone your skills.

BEA, open enough to survive?

StorageSwiss George Crump Profile: StorageSwiss

It’s probably a sign of our times that we view BEA Systems Inc. as a little fish unable to defend itself against larger predators in the software industry ocean. According to its 3rd quarter financial report, BEA is on track to rake in $1.5 billion this year. It still needs to prove in the 4th quarter it hasn’t been crippled by Oracle Corp.’s $6.7 billion October takeover bid, which it rejected, but a conversation I had last week with a BEA customer proved enlightening.

The customer in question, a CTO whom I contacted on a totally separate matter and wished to remain anonymous, believes BEA’s approach to technology can help it weather this storm.

“They adhere to standards and their tooling is open enough that we see no reason to stay away,” he said. “If a change we didn’t like occured after a takeover, we don’t feel like we’d be locked in with BEA. They get loose coupling. We could unplug from them if we had to.”

His basic argument was that BEA has become open enough and embraced heterogeneity to the extent that it can continue to compete for customers based on functionality. It’s got a service-oriented defense system.

“We need technology that works,” he said. “This takeover drama might be interesting to Wall St., but it has nothing to do with my projects. From a user standpoint, BEA was in more trouble four or five years ago when we weren’t sure if they were going to embrace more open systems. They did and because of that we’ll continue to look at them.”

He reinforced what we already know, BEA has proven successful at selling software during the past decade and it shouldn’t be taken for granted that users will stay away from a vendor that has delivered for them in the past. This isn’t some overly leveraged wannabe without the means to support itself. BEA has been a viable player in the app dev space.

Here’s something I wrote in October about why Oracle might want BEA:

While there’s massive overlap between BEA’s offering and Oracle’s Fusion line, BEA does have three particular strengths that Oracle might be looking to leverage: data services, internal portals and external transactions. Those were the three most popular types of service-based applications our users reported they are either working on or plan on undertaking in the next year. Even more importantly, the demand for these types of applications increased sharply with respondents who reported their companies had achieved some measure of architectural maturity. In other words, the farther along users are with SOA, the more important those projects are likely to become.

BEA has its AquaLogic Data Services Platform, it has its WebLogic Portal product as well as the portal functionality it acquired when it bought Plumtree Software in 2005, and it has the Tuxedo transactional business on which it built itself. So the BEA goose might be sitting on a few golden eggs … and that’s not a bad pet for a would-be giant to have.

Yet if that’s a good set strengths for Oracle to buy, then it’s also a good set of strengths for BEA to have. If a user has a data services, portal or transactional project in the works, then BEA (which reports that more than 60% of its revenues are derived from services) stands to be a player.

While the Oracle bid surely staggered BEA, don’t be surprised to see BEA do a fair job of fighting back this quarter. The fact that it has enough going for it to be a takeover target also means it might have enough going for it to fend off Oracle’s advances.

SOA, IT’s chameleon architecture

StorageSwiss George Crump Profile: StorageSwiss

I was reading a recent blog entry by Joe McKendrick in which he noted that service-oriented architecture can save money during hard times and add revenue during good times. It got me thinking about something I’ve heard fairly regularly over the years, namely that SOA often sounds like something out of an infomercial.

You mean SOA slices, dices, chops, cooks things to perfection, cleans up easily, prepares healthier food and has zero environmental impact? You almost expect Ron Popeil to pop out from around the corner and announce that, “But wait, there’s more.”

Let’s face it, SOA sometimes sounds too good to be true. It also leads one of the great misconceptions about SOA, that it’s a tidy thing you can buy. People want SOA to be tangible. They want to be able to point to it and say, “There’s my SOA.” It’s why so many glommed onto the enterprise service bus concept. The ESB is a piece of integration middleware that follows certain service-oriented principles, but many made the mistake of thinking that buying an ESB gave you a de facto SOA. It’s a natural reaction. When something new and compelling comes along, you want it in your hands, preferably now.

Yet SOA isn’t some secret spice that comes in its own box, something you can add liberally to every project. SOA is a consistent and sensible approach to architecting your business. It’s rigor and diligence more than technology.

This week we’ll get deeper into that issue with a podcast with esteemed IT analyst and co-author of “Service Oriented Architecture for Dummies” Judith Hurwitz, in which she directly addresses the whole faulty concept of “SOA in a box.”

That brings me back to the (fair) complaint that SOA sounds too good to be true. Critics are correct that no one thing will solve all your app dev problems. That said, rigor and diligence in building a modular, adaptable architecture is exactly the sort of thing that can help you in mulitple, often diametrically opposed, situations. When the bad times hit, it can help you with cost containment. When the good times hit, it can help you seize opportunities. That’s what an adaptable infrastructure does.

Just last week, we had a story that noted an SOA infrastructure had helped Sprint/Nextel speed up integration with new trading partners twentyfold. That’s a case of saving you money and making you money in one fell swoop. Doing things in a service-oriented manner creates business agility, which is the real goal.

Building a more agile business isn’t something that sounds too good to be true. Large numbers of companies are doing it right now and they are reaping the benefits. It may be hard work, it may require creative approaches to change the corporate culture, but it is not a flimflam promise. SOA is an approach to technology, which opens up a greater number of business possibilities. It can promise more because flexibility is at its very core.

Podcast: SOA, composite applications and data integration

StorageSwiss George Crump Profile: StorageSwiss

Web services and composite applications, like traditional monolithic apps, rely on data. Without the right data at the right time, the service/application has nothing to execute. In this podcast, Nexaweb Inc. COO David McFarlane talks about how composite applications involve much more than just some slick tools that make eye-popping front ends. He touts data integration as a key element in composite application development and the creation of dynamic user interfaces.

Listen to the podcast

Among the topics covered are:

  • The semantic technical challenges involved with data integration
  • The organizational governance needed to facilitate data integration
  • The creation of real-time, event-driven UIs
  • Event-level integration in mashup services
  • The role of business intelligence in composite development and service agility
  • What constitutes a true rich user interface

10 ways SOA is like a Thanksgiving meal

StorageSwiss George Crump Profile: StorageSwiss

It’s that time of year where people dust off old chestnuts, revive traditions and take a wistful look back. This is something we ran in 2005 as part of a newsletter, but it never had an official home in cyberspace. It only seems fitting that we rectify that situation.

Information technology is a serious business, certainly it’s one we take seriously. Even with a major national holiday looming this Thursday we’ll keep bringing you the latest in SOA, Web services and integration news.

Yet, let’s face it, you probably aren’t going to be making that enterprise-altering decision this week or going live with your latest architectural achievement. Too many people will be skipping out early and trying to beat the traffic, with gravy-covered visions dancing in their heads.

We at recognize that. This isn’t the week you’re going to change the world. Rather it’s a week to reflect on what you’ve been doing and what projects will soon be on your plate. With that in mind, here’s our top 10 reasons why service-oriented architecture is like a Thanksgiving meal:

  1. Like a Thanksgiving meal, it takes a lot of work to put together an SOA … and no one wants to clean up the associated mess that comes with it.
  2. Reuse, the next round of Web services you build are the IT equivalent of next week’s turkey sandwiches and soups. You should be getting a lot of meals out of this feast.
  3. Unless you find a way to spice it up or make it savory, SOA can be dry and a lot of people around the table may quickly lose interest. Also, like a big turkey meal, too much SOA can put you to sleep.
  4. An SOA project can bring together a lot of people you rarely see. In fact, you probably aren’t sure you want to see some of them.
  5. SOA can give rise to lots of interesting combinations, kind of like turducken (a chicken stuffed inside a duck stuffed inside a turkey).
  6. Everyone offers up advice on how to cook up an SOA, but they always leave you with the distinct feeling that they aren’t so sure these tips actually work.
  7. Standards, on Thanksgiving the standards are turkey, mashed potatoes, gravy, stuffing and cranberry sauce. In SOA it’s WS-* specifications and communication protocols.
  8. You can undertake lots of small projects while you’ve got your SOA bird in the oven
  9. It takes a solid network and good communication to move all the food around a Thanksgiving table so that everyone gets to pick exactly what they want. In many ways, it’s a service-oriented meal dependent on a loosely-coupled infrastructure.
  10. Screw up your SOA and you’ll never hear the end of it.

SOA bloggers wanted

StorageSwiss George Crump Profile: StorageSwiss

We at are looking for the next generation of leaders in the app dev space.

You see, we’ve got this new blogs section (you’re reading it right now) and we know we’ve got some budding stars out there. We offer a heck of a nice platform with nearly 500,000 site members. It offers the chance to establish yourself as a thought leader in an arena that has become critical to the enterprise.

So who are we looking for?

First, we’re interested in end users and integrators. Nothing against vendors, but they already do a fine job of getting out the word on their particular slant on things. What we want is the people who are trying to make service-oriented architecture work, the folks who’ve had to roll up their sleeves to tackle the untamed world of service orientation. Make no mistake about it, the best resource in this industry is the user community. It’s where the best, most incisive information can be found. We’ve got the platform from which you can be heard, all we need is folks who have something to say.

Second, have a focus. SOA is a broad topic and a good blog will find a solid niche inside of it. It could be data integration or architectural design or runtime management or REST or composite applications or WS-* standards or BPM/event handling or security or network issues. It really depends on where your expertise lies. We’re open to suggestion. What we want is smart, articulate people who want to interact with the larger SOA community. Pick your topic and let us know what issues inside of that topic you plan to cover.

Third, send us a sample. It doesn’t have to be “War and Peace”. In fact, since it’s a blog we’re talking about, “War and Peace” would be overkill, but we will need to see a sample of your writing to get an idea of what to expect from you. This is going to be a blog, so you’re going to have a lot of freedom. We won’t be editing your stuff for spelling and grammar. As such, we need to make sure we’ve got bloggers who are capable and confident writers.

Fourth, remember this is a blog and not a weekly column. A good blog is a busy blog. It’s great if you want to make a regular column-style entry part of the blog, but remember to punctuate it with quick insights and links to what you think is valuable other content. A good idea can take you a long way. If it’s a good idea that can be summed up in three paragraphs, that’s fine.

If you’re interested, send your writing sample, a quick explanation of the topic you’d like to cover and a short bio to If we like it, you’re on the blog roster. It’s that easy. You can be impressing colleagues, friends, family and would be (or ongoing) love interests in no time. Part of our site relaunch effort is to give our community more of a voice and this is a major initiative for us. Users never have needed sober advice from their peers more than they do right now. Can you be one of the people who steps up to provide it?

And don’t forget about our current reader contest. Maybe you’ve got a lesson learned to share with the community, but you want us to write it up for you (because we’ve got professionals who are paid to do that sort of thing). Well, this contest would be right up your alley in that case. Winners will receive a copy of Thomas Erl’s new book, “SOA: Principles of Service Design” as a thanks for their participation.
