It did not choose more than one failure boundary inside that region.</p> <p>This is why <em>region</em> and <em>availability zone</em> are not interchangeable location labels. <strong>A cloud region is a broad geographic area in which a provider operates services. An availability zone is an isolated deployment area inside a region, designed to reduce the chance that one local infrastructure failure affects every copy of a workload.</strong></p>
