A lot of infrastructure demand in the GCC isn't a refresh cycle. It's a national strategy with a deadline.
In mature markets, IT spend mostly follows the business. A company needs something, so it buys it.
Here, much of it runs the other way. National programmes such as Saudi Arabia's Vision 2030 name digital infrastructure as a priority and attach dates to it. Whole sectors then modernise on that timetable.
If you sell or design here, expect the reason for a project to be a national objective, and expect the deadline to come from policy rather than from the technology. "Why now?" usually has a national answer.
Read it as ordinary refresh demand and you'll misjudge the pace.
