<h2 id="safekit-brings-two-solutions-for-redundancy-and-high-availability-of-a-scada-software">SafeKit brings two solutions for redundancy and high availability of a SCADA software</h2>
<h3 id="redundancy-and-high-availability-at-the-application-level">Redundancy and high availability at the application level</h3>
<p>In this type of solution, only application data are replicated. And only the application is restared in case of failure.</p>
<img src="/wp-content/uploads/2023/02/application-ha-4.png" width="168" alt="Redundancy at the application level for a SCADA  software">
<p>With this solution, restart scripts must be written to restart the application. This solution is platform agnostic and works with applications inside physical machines, virtual machines, in the Cloud. Any hypervisor is supported (VMware, Hyper-V&hellip;).</p>
<ul>
<li>Solution for a new application (restart scripts to write): <a href="/solutions/windows-high-availability-software-synchronous-replication-failover/">Windows</a>, <a href="/solutions/linux-high-availability-software-synchronous-replication-failover/">Linux</a></li>
</ul>
<h3 id="redundancy-and-high-availability-at-the-virtual-machine-level">Redundancy and high availability at the virtual machine level</h3>
<p>In this type of solution, the SCADA software is put inside a virtual machine. The full Virtual Machine (VM) is replicated and restarted (Application + OS).</p>
<img src="/wp-content/uploads/2023/02/vm-ha-4.png" width="186" alt="Redundancy at the virtual machine level for a SCADA software">
<p>The advantage of this solution is that there is no restart scripts to write per application. This solution is generic for any SCADA software. It works with Windows/Hyper-V and Linux/KVM but not with VMware. This is an active/active solution with several virtual machines replicated and restarted between two nodes.</p>
<ul>
<li>Solution for a new application (no restart script to write): <a href="/solutions/hyper-v-replication-automatic-failover-load-balancing/">Windows/Hyper-V</a>, <a href="/solutions/linux-kvm-high-availability-replication-automatic-failover-load-balancing/">Linux/KVM</a></li>
