title: AWS availability zone logical or physical?
body: <p>quoting AWS:</p>
  <blockquote>
  <p>AWS has the concept of a Region, which is a physical location around the world where we cluster data centers. We call each group <strong>of logical data centers an Availability Zone</strong>. Each AWS Region consists of <strong>multiple, isolated, and physically separate AZs within a geographic area</strong>.</p>
  </blockquote>
  <p>I'm confused by the meaning of &quot;logical data centers&quot; here: if AZ are physically separated data centers, I would assume the ressources are physical too, wouldn't be more appropriate to say &quot;physical data centers&quot;? or maybe am I wrong on the definition of logical here ?</p>
