Embrane powering PEER1 Hosting

SDN enabled cloud hosting

As I enjoy my employer mandated shut-down and gaze sleepily at the phone on my desk, my mind begins to wander… Today we use services from companies like Vonage and make international calls over high speed IP networks.  Vonage in turn operates a global network using the services of cloud hosting companies like PEER1 Hosting.  PEER1 claims to have 20,000 servers worldwide, own 13,000 miles of fiber optic cable, 21 Points of Presence (POP) in 2 continents, 16 data centers in 13 cities around the world.  Like any large hosting provider they use networking gear from vendors like Juniper and Cisco.  Their primary data-center in the UK is said to deploy Juniper gear: EX-series Ethernet switches with virtual chassis technology,  MX-series 3D edge routers,  and SRX series services gateways.   However when they wanted to offer customers an automated way to spin up firewalls, site-to-site VPNs and load balancers in a matter of minutes they ended up using technology from Embrane a 40-person start-up in the crowded area of SDN start-ups.

Why did they not use SDN solutions from Juniper their vendor of choice for routers and switches?    Juniper initially partnered with VMware to support NSX for SDN overlays and Juniper was a platinum member of the OpenDaylight project.  Then Juniper did an about-turn and acquired Contrail a technology that competes with VMware.   Juniper claimed that despite not supporting OpenFlow, the Contrail SDN controller will offer greater visibility into layer 2 switches due to the bridging of BGP and MPLS.  Unlike the Cisco SDN solution which prefers Cisco hardware, Juniper claimed that Contrail would work with non-Juniper gear like that from Cisco.  To generate interest from the open source community in Contrail, Juniper open sourced OpenContrail – though most of the contributors to OpenContrail on GitHub are from Juniper.

It is interesting to note that customers like Peer1 may rely on Juniper or Cisco for their hardware but when it comes to finding an automated way to deploy networking services as an overlay they go with start-ups like Embrane.  Embrane has an interesting concept: Their technology allows a hosting provider to overlay firewalls and load balancers using vLinks which are point-to-point layer3 overlays capable of running over any vendor hardware (not just Cisco or Juniper).  Many such vLinks are part of a single administrative domain called vTopology.    Embrane allows you to make a single API call to bring up or bring down an entire vTopology.  An example of how this makes life easier for a hosting provider: When an application is decommissioned all associated firewall rules are also decommissioned unlike other methods where you end up with firewall rules living past their time.

I will watch with interest to see if companies like Embrane and PlumGrid end up turning the SDN world on its head and pumping some adrenalin into the dull world created by hardware vendor monopolies and their interpretation of SDN.
