QuestionQ16

Understand the digital product lifecycle in terms of the ITIL ‘operating model’

One of an organization’s legacy systems is hard to change because it is tightly coupled. To stay competitive, the organization must identify a way to make changes to this system more frequently.

What would the architecture management practice recommend?

  • A Iteratively moving application functionality to microservices
  • B Leveraging infrastructure as code to speed up development
  • C Using continuous integration/continuous delivery techniques
  • D Using blue/green deployments to minimize the impact of changes
Explanation

Architecture management guides the evolution of systems toward an architecture that supports required business agility. Iteratively moving functionality from a tightly coupled legacy application into microservices reduces coupling and enables components to be changed and deployed more independently.
