In one word – The operations guys (Directors/Leads/VPs)
While ARA refers to applications being deployed on target environments and hence should be the focus of the developers, the fact is that most IT organizations see this as an Ops function. Their logic is simple – any deployment to the production environment is a “change” to that environment and hence has to be managed by Infrastructure and Operations (INO) team.
Developers still influence the tool but it is the operations team that doles out the budget for any such tool.
Surprisingly, too many vendors don’t understand this nuance and keep positioning their ARA tools to developers – who have an opinion but little purchasing power in this space.
