With the pace of digital transformation and AI, organisations are under increasing pressure to modernise, often at speed.

In reality, that’s where the risk starts.

In my experience working with IBM Z and across enterprise environments, availability isn’t a feature you switch on. It’s the result of how architecture, operations, and people perform together under pressure.

The real question is:

In this article, I have shared my perspective on why high availability is something you continuously earn, not something you configure once.

Curious how others are validating this in practice, particularly where availability assumptions are being challenged.
