A SearchSOA.com blog


The SOA blog with observations and commentary for architects and developers about SOA, Web services, integration technologies (ESBs, Grids, XML) and development platforms such as Java EE and .NET

SOA, IT’s chameleon architecture

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

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

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 SearchSOA.com 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

We at SearchSOA.com 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 mmeehan@techtarget.com. 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.

Caught in a sea of SaaS

Over on her ebizQ blog, Krissi Danielsson has noted that the buzzword success of Software as a Service (SaaS) has spawned numerous aaS imitators, including Data, Architecture and Voice all “as a Service.” In his ZDNet blog, Phil Wainewright added that aaS is redundant because the very function of business is to provide services.

It’s about time some sane, responsible folks pointed out that we’re heading into buzzword overkill with “as a service.” Yet we’d be remiss if we didn’t have some irresponsible fun with aaS before it becomes yesterday’s catchphrase.

For instance, here’s a list of software possibilities that still haven’t had their aaSes handed to them:

  • Hidden License Fees as a Service (HLFaaS)
  • Stovepipe Application Sprawl as a Service (SASaaS)
  • Integration Spaghetti as a Service (ISaaS)
  • Every Vendor Insures Lock-in as a Service (EVILaaS)
  • Must Upgrade to the Expensive Enterprise Version If You Want It to Scale as a Service (MUttEEVIYWItSaaS)
  • Rogue Services as a Service (RSaaS)

Also, as we all know fortune cookie proverbs are made infinitely better by adding ‘in bed” at the end. Let’s try that with “as a service.”

  • Count your blessings by thinking of those whom you love … as a service.
  • Plan for many pleasures ahead … as a service.
  • Something you lost will soon turn up … as a service.
  • Good things are being said about you … as a service.
  • Fame, riches and romance are yours for the asking … as a service.
  • A friend asks only of your time … as a service.
  • Romance comes into your life this year in a very unusual sort of way … as a service.
  • Stop and smell the roses … as a service.
  • Someday you shall see a wise person in the mirror … as a service.
  • He who shows too much cheek to a lady may have it slapped … as a service.
