In a #data center context, Reliability (No #downtime, ever) is often considered the number one priority: 1) Even a few minutes of downtime can #cost thousands or millions depending on the #business. 2) Reliability directly affects #slas (Service Level Agreements), user #trust, and operational continuity. 3) Without reliability, other goals like #resilience and #sustainability become less relevant. That said, the ultimate goal is to balance all 3 pillars, reliability, resilience, and sustainability. Still, reliability typically takes the lead, especially for mission-critical environments like #finance, #healthcare, or #hyperscale operations. #dc #datacenter #datacentre
