High availability software - HA cluster for redundancy of critical applications on Windows and Linux

Evidian SafeKit

30 seconds elevator pitch for SafeKit

  • Sam is in charge of critical applications
  • Critical applications are not available anymore!

SafeKit, a Simple High Availability Software Easy to Deploy

All-in-one high availability

In one software product, SafeKit provides on Windows and Linux:

  • load balancing
  • synchronous real-time file replication
  • automatic application failover
  • automatic failback after a server failure

Save costs of network load balancers or dedicated proxy servers, shared disk or replicated SAN storage, enterprise editions of Operating Systems and databases, specific skills to maintain operational a cluster.

A complete solution

SafeKit solves:

  • hardware failures (20% of problems), including the complete failure of a computer room,
  • software failures (40% of problems), including restart of critical processes,
  • and human errors (40% of problems) thanks to its ease of use and its web console.

A generic product

You can implement with the SafeKit product real-time replication and failover of any file directory and service, database, complete Hyper-V or KVM virtual machines, Docker, Podman, K3S, Cloud applications (see the module list).

Zero specific skills

No special computer skills are required to deploy a SafeKit high availability cluster.

Zero hardware extra costs

Forget about shared disks, replicated SAN storage... SafeKit is hardware independent and runs on your existing physical servers, or in virtual machines, or in the cloud.

Zero software extra costs

SafeKit works with the standard editions of Windows and Linux and does not require enterprise editions of databases.

Choose between redundancy at the application level or at the virtual machine level

Redundancy at the application level

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

Application HA - redundancy at the application level

With this solution, restart scripts must be written to restart the application.

We deliver application modules to implement redundancy at the application level. They are preconfigured for well known applications and databases. You can customize them with your own services, data to replicate, application checkers. And you can combine application modules to build advanced multi-level architectures.

This solution is platform agnostic and works with applications inside physical machines, virtual machines, in the Cloud. Any hypervisor is supported (VMware, Hyper-V...).

  • Solution for a new application (restart scripts to write): Windows, Linux

Redundancy at the virtual machine level

In this type of solution, the full Virtual Machine (VM) is replicated (Application + OS). And the full VM is restarted in case of failure.

VM HA - redundancy at the virtual machine level

The advantage is that there is no restart scripts to write per application and no virtual IP address to define. If you do not know how the application works, this is the best solution.

This solution 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.

Partners, the success with SafeKit

This platform agnostic solution is ideal for a partner reselling a critical application and who wants to provide a redundancy and high availability option easy to deploy to many customers.

With many references in many countries won by partners, SafeKit has proven to be the easiest solution to implement for redundancy and high availability of building management, video management, access control, SCADA software...
