Innovative Multicloud ROC Architecture

Your data always accessible

Replicate your data between the hosts of your choice among our 8 partners for a total of 31 locations in 13 different countries.

Benefit from two exclusive advantages:

  • - Your data remains accessible even when a provider suffers a failure, a cyberattack or any other incident since you are no longer dependent on a single provider
  • - Access to your data is guaranteed at 99.999% compared to 99.9% of most competitors. This means that on average your data is unavailable for less than 5 minutes per year compared to 8 hours with our competitors

At Arzen, you no longer have to fear the unavailability or the loss of data.
