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 complexities and challenges and makes testing a critical component of the development lifecycle. Teams need to think about: How do you know if the solution is ready? How do you know that it will scale to accommodate future needs? How do you know that you can actually get the business flexibility that SOA promises? These are all questions testing should answer, but many test teams aren't experienced yet in testing service-oriented solutions. This article contains a set of recommendations, with a rationale, that will help you to mitigate the issues that arise in testing an SOA solution. The re... (more)

SOA Security Gets Cloudy

I’m with the SOA Work Group at The Open Group conference in Toronto this week (see http://www.opengroup.org/toronto2009-apc). The Work Group has been busy recently, completing its Governance Framework, helping to complete The Open Group’s Service Integration Maturity Model, and working with members of OASIS and the OMG to finish the joint paper “Navigating the SOA Open Standards Landscape Around Architecture,” which explains how the architecture-focused SOA standards of these bodies relate to each other. There was so much to do that we started our discussions last weekend, and we ... (more)

A Peaceful Leap to Cloud Computing

History has many examples of invaders wielding steel swords, repeating rifles, or whatever the latest weapon may be, driving out people who are less well-equipped.

The Open Group Cloud Computing Work Group has been focused on the business reasons why companies should use cloud computing. The Work Gro... (more)

Cloud Computing and Enterprise Architecture

The Open Group Conference in San Diego last week included a formal cloud computing conference stream on Wednesday, followed in that evening by an unstructured CloudCamp -- which made an interesting contrast. The cloud conference stream The Cloud Conference stream featured presentations on architecting for cloud and cloud security, and included a panel discussion on the considerations that must be made when choosing a cloud solution. In the first session of the morning, we had two presentations on architecting for cloud. Both considered TOGAF as the architectural context. The first, ... (more)

Enterprise Transformation, Enterprise Architecture, SOA, a Splash of Cloud

This week, I've been at The Open Group Conference in San Francisco. The theme was Enterprise Transformation which, in simple terms, means changing how your business works to take advantage of the latest developments in IT. Evidence of these developments is all around. For example, when I took a break and went for coffee and a sandwich to a little cafe on Pine and Leavenworth, it seemed to be run by and for the Millennial Generation. True to type, my server pulled out a cellphone with a device attached through which I swiped my credit card. An app read my screen-scrawled signature a... (more)
