Enterprise Architecture is necessary regardless of changes to underlying technologies. If managed properly, Enterprise Architecture will iterate and adjust to the winds of change. Client/server, SOA, RFID, Cloud, and other technology developments should be considered as styles, but Enterprise Architecture is at the heart of change. Cloud computing should have little impact on Enterprise Architecture. It is the role of the Enterprise Architecture team to: · Investigate if any style is simply hype or whether it holds real business value · Understand the benefits and risks of a specific style · Communicate these to Business and IT · Develop an adequate governance framework · Align the “style” with business requirements · Give guidance for sustainable innovation If Cloud computing does not take Enterprise Architecture into consideration, it will result in “spaghetti clo...

This presents a particular challenge to Enterprise Architecture. Generally speaking, IT departments have all sorts of criteria to justify projects and measure their performance. They use measurements and metrics, KPIs. Going to the solution level, they commonly use indicators such as percentage uptime for systems from the System Management team, error rates for applications from th... (more)

Implementing SOA through TOGAF 9.1: the Center Of Excellence

Service-oriented architecture (SOA) has at times been challenged but is now on the verge of mainstream acceptance. It now shows maturity, success and even signs of popularity. Service Oriented Architecture (SOA) is an enterprise scale architecture for linking resources as needed. These resources are represented as business-aligned services which can participate and be composed in a set of choreographed processes to fulfil business needs. The primary structuring element for SOA applications is a service as distinct from subsystems, systems, or components. A service is an autonomous ... (more)
