For the architectural rationale behind these features, see the <a href="https://cloudmanaged.online/platforms/pextra-cloudenvironment/">full platform profile</a> .</p> <hr> <h2 id="1-distributed-control-plane-cockroachdb">1. Distributed Control Plane (CockroachDB)</h2> <table> <thead> <tr> <th>Capability</th> <th>Detail</th> </tr> </thead> <tbody> <tr> <td>Database engine</td> <td>CockroachDB — distributed, ACID-compliant SQL over Raft consensus</td> </tr> <tr> <td>High availability</td> <td>No primary node; any control-plane node handles any API request</td> </tr> <tr> <td>Fault tolerance</td> <td>Survives loss of <code>(n−1)/2</code> control-plane nodes without API interruption</td> </tr> <tr> <td>Scalability</td> <td>Horizontal scale-out by adding control-plane nodes; no vCenter-style vertical sizing</td> </tr> <tr> <td>Transaction guarantees</td> <td>Serializable isolation for all VM state, quota, and billing operations</td> </tr> <tr> <td>Metadata sync</td> <td>Consistent view of all cluster state globally within milliseconds</td> </tr> </tbody> </table> <p><strong>Operational benefit</strong>: Eliminates the &ldquo;vCenter is down, nothing works&rdquo; scenario. Control-plane maintenance, upgrades, and even node failures do not create provisioning blackouts.</p>
