According to TOGAF, which of the following best describes the classification of architectural change in the case where multiple server systems are being consolidated to a single system?
According to TOGAF, which of the following best describes the classification of architectural change in the case where multiple server systems are being consolidated to a single system?
Consolidating multiple server systems into a single system is primarily a simplification change because it reduces complexity and the number of systems being managed without fundamentally altering the overall architecture. This type of change can be effectively handled using change management techniques, as it primarily impacts the infrastructure and technology layers, simplifying the existing architecture to achieve cost savings or operational efficiency.
The Change Management Process Simplification change: A simplification change can normally be handled via change management techniques. --- Guidelines for Maintenance versus Architecture Redesign For example: If the change is at an infrastructure level - for example, ten systems reduced or changed to one system - this may not change the architecture above the physical layer, but it will change the Baseline Description of the Technology Architecture. This would be a simplification change handled via change management techniques. https://pubs.opengroup.org/architecture/togaf8-doc/arch/chap14.html
15.5.2 - Enterprise Architecture Change Management Process Another way of looking at these three choices is to say that a simplification change to an architecture is often driven by a requirement to reduce investment; an incremental change is driven by a requirement to derive additional value from existing investment; and a re- architecting change is driven by a requirement to increase investment in order to create new value for exploitation.
Correct Answer simplification change - to an architecture is often driven by a requirement to reduce investment incremental change - It is driven by a requirement to derive additional value from existing investment re-architecting change - It is driven by a requirement to increase investment in order to create new value for exploitation.
Simplification change: a simplification change can normally be handled via change management techniques Incremental change: an incremental change may be capable of being handled via change management techniques, or it may require partial re-architecting, depending on the nature of the change (see 15.5.3 Guidelines for Maintenance versus Architecture Redesign for guidelines) Re-architecting change: a re-architecting change requires putting the whole architecture through the architecture development cycle again
If the change is at an infrastructure level — for example, ten systems reduced or changed to one system — this may not change the architecture above the physical layer, but it will change the Baseline Description of the Technology Architecture; this would be a simplification change handled via change management techniques - Answer is "E"
