Back in the old good days of enterprise software, we did not need to worry about our customers. We delivered bits on DVDs – it was up to the customers to struggle with installation, integration, management, customization and other aspects of software operations. We collected all ...Oct. 2, 2009 09:30 PM EDT Reads: 1,647
A recent survey from F5 indicates that the cloud computing movement is making significant headway despite what some may see as mere fluff and hype. The survey comprised of employees from large enterprises (2500+ employees), indicated that 82% of respondents are in some stage of public ...
ZapThink considers the SOA business case as an essential SOA artifact. Architects must have a clear picture of the business motivations for SOA, not only at the beginning of the initiative, but also as the architecture rolls out. Nevertheless, there is still frequently a disconnect bet...
So, in this morning’s email I received a notification from ActiveVOS that their CTO is a primary contributor to a new book recently released on Service Component Architecture (SCA). Having just recently completed a full investigation into SCA, two things jumped out at me: 1) SCA is he...
Defining cloud computing has proved to be nearly impossible. Ask ten different people and you'll get ten different answers. Perhaps it's time to move past trying to define the cloud and look into the common characteristics of such solutions.
This is a blog about the importance of cloud solutions that are organized as services. As more and more cloud computing offerings hit the market, I think it is becoming increasingly important that users understand what to look for in such solutions. It is one thing to provide something...
There’s no shortage of opinions on how cloud computing and SOA are related. Just plug the phrase into your favorite search engine and you’ll have a day’s worth of reading. What you are likely to find are articles discussing how SOA led to cloud computing, how a good SOA is a prerequisi...
We’ve been having quite a few discussions with analysts over the past few months on the subject of “cloud”. The interesting thing about these discussions is the vast array of points of view from which those analysts are viewing “cloud”. Some are focused on the network aspects, others o...
I’ve been in several meetings recently that have hit on the topic of Data.gov. Data.gov will become a repository for all the information the government collects, and that information will be in turn available to anyone who needs it. Pretty positive move, if you ask me. However, th...
McKinsey announced a report on Cloud computing, claiming that the economics only made sense for small and medium sized companies but not for enterprises with their own data centers. The analysis then compared the cost of using Amazon's service with the cost of a typical data center. ...
As SOA moves from the project level to the enterprise, SOA architects and practitioners quickly realize the need to consider common services and data management issues. Today we seek the right approaches and the proper enabling technology and standards to provide our enterprises with a...
Service Oriented Architecture (SOA) has been discussed as an important architectural style for the last few years. Organizations have started to develop service-oriented solutions and many are now leveraging services in their production environments. SOA introduces new technical comple...
'Our processes are bulletproof. Nothing gets into production that doesn't go through the proper and complete approval process.' Famous last words uttered by far too many enterprise architects. Some of them actually believe it's true - others think that by hoping it's true, maybe, just ...
To be able to adapt to market changes, organizations tend to focus on flexibility and responsiveness. The IT challenge has usually been to support this business vision with the appropriate architectures and technologies.
Service-oriented architecture (SOA) is never established in a vacuum. In any real life situation, an existing IT environment must be taken into consideration, offering functionality -- and data -- that cannot simply be replaced by a set of new services. Hence, a key aspect of building ...
In the previous article (part 1 in WebSphere Journal vol: 3. iss: 4) we began to build an SCA project in WebSphere Process Server. Here in part 2 we pick up the discussion. To see the associated images, please view the article online at www.ibm.com/developerWorks/websphere.
Explore different Service-Oriented Architecture (SOA) antipatterns, which are descriptions of commonly occurring situations or solutions that generate decidedly negative consequences. With more businesses taking major steps to move from Web services to SOA, barriers to the introduction...
You may be thinking, oh great, not another programming model. What about Web services? What happened to Enterprise JavaBeans? Well, Service Component Architecture (SCA) is not meant to replace or compete with any existing programming models. Instead, SCA gives you a model to define int...
The architectural consideration of SOA in the preceding chapter offers advice on what directions to choose and how to define the strategic goals for an SOA project. This chapter takes the next step toward execution by focusing on how to plan an SOA project. The topics in this chapter c...
The WebSphere Integration Reference Architecture rigorously recognizes the need for a comprehensive software development platform as core. It's important that the development platform encompasses the entire lifecycle of software development, including requirements analysis, modeling an...
