# High Availability and Redundancy for Physical Security Software

## SafeKit brings two solutions for redundancy and high availability of a physical security software

### Redundancy and high availability at the application level

In this type of solution, only application data are replicated. And only the application is restared in case of failure.

This solution requires a technical understanding of the application. You need to define which services to restart, specify the application folders to replicate, and configure a virtual IP address for failover. But this solution is platform agnostic and works with applications inside physical machines, virtual machines, in the Cloud. Any hypervisor is supported (VMware, Hyper-V...).

### Examples

  * Video management: 💡 [Milestone (Management, SQL, Log, Event)/SafeKit](https://safekit.eviden.com/solutions/milestone-xprotect-corporate-high-availability-synchronous-replication-failover/)
  * Video management: 💡 [Genetec (SQL)/SafeKit](https://safekit.eviden.com/solutions/genetec-sql-server-the-simplest-high-availability-cluster-with-synchronous-replication-and-failover-between-two-redundant-servers/)
  * Access control: 💡 [Nedap (AEOS, SQL)/SafeKit](https://safekit.eviden.com/solutions/nedap-high-availability-synchronous-replication-failover/)
  * New application (define services to restart, application folders to replicate, a virtual IP address for failover): 💡 [Windows](https://safekit.eviden.com/solutions/windows-high-availability-software-synchronous-replication-failover/), 💡 [Linux](https://safekit.eviden.com/solutions/linux-high-availability-software-synchronous-replication-failover/)

### Redundancy and high availability at the virtual machine level

In this type of solution, the physical security software is put inside a virtual machine. The full Virtual Machine (VM) is replicated and restarted (Application + OS).

![Redundancy at the virtual machine level for a physical security software](https://safekit.eviden.com/wp-content/uploads/2023/02/vm-ha-4.png "w:184")

The advantage of this solution is that it does not require a technical understanding of the application; you only need to define the location of the VM files where the application is installed. This solution is generic for any physical security software. However, it works only 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.

### Examples

  * Building management: 💡 [Siemens Desigo CC/SafeKit](https://safekit.eviden.com/solutions/siemens-desigo-cc-redundancy-high-availability-cluster-active-active/)
  * Video management and access control: 💡 [Siemens Siveillance suite/SafeKit](https://safekit.eviden.com/solutions/siemens-siveillance-redundancy-high-availability-cluster-active-active/)
  * New application (define the location of the VM files folder where the application is installed): 💡 [Windows/Hyper-V](https://safekit.eviden.com/solutions/hyper-v-replication-automatic-failover-load-balancing/), 💡 [Linux/KVM](https://safekit.eviden.com/solutions/linux-kvm-high-availability-replication-automatic-failover-load-balancing/)
