Didn&#x27;t understand much from the linked page, but I found this website (from Pivotal, the commercial entity behind Geode) quite informative. Perhaps it&#x27;s useful to others.<p><a href="https:&#x2F;&#x2F;pivotal.io&#x2F;big-data&#x2F;pivotal-gemfire" rel="nofollow">https:&#x2F;&#x2F;pivotal.io&#x2F;big-data&#x2F;pivotal-gemfire</a><p>===<p>I found this interesting deployment:<p><pre><code>    China National Railways use Geode to run railway ticketing for the entire 
    country with a 10 node cluster, managing 2 TB of &quot;hot data&quot; in memory, 
    and 10 backup nodes for high availability and elastic scale.
    
    Holiday travel periods [Chinese New Year&#x27;s] create peaks of 15,000 tickets 
    sold per minute, 1.4 billion page views per day and 40,000 visits per second.
