Virtual rack technology enables services to be connected, isolated or spread across one or multiple private secure networks. Users can build private infrastructures on a global multi-datacenter scale using unique network technologies. Isolate critical servers within a private VLAN; data is secure, and communication between servers is not routed via the public network. Deploy up to 4,000 private VLANs to isolate servers and filter customer access. Build infrastructure using OVH's infrastructure, storage, Big Data and private cloud offerings.
