AppNexus

AppNexus provides the infrastructure building blocks needed to deploy and manage high-availability production infrastructure quickly, securely, and reliably, with a minimum of capital expense.

• High-end dedicated servers, which you can provision in minutes with the OS image of your choice
• Geographically disparate data centers, with dns technology to route users to the closest one
• Carrier-class networking, redundant from box to backbone at 1GigE or more
• Private vlans and configurable firewalls to protect your data
• Global and local load balancing on redundant f5 machines
• Isilon storage cluster with tens of terabytes of capacity and 300Mb/s performance

These building blocks are provisioned on demand using a single set of apis and command-line tools.
Adding a new instance takes under five minutes; configuring a complex load-balanced application
takes under an hour.
The simplicity of infrastructure as a service means a minimum of headaches and hr investment.
And production-class slas, 24/7 phone and email support, and internal and external monitoring
make AppNexus a perfect fit for the enterpris.

Datacenters

Several racks in our NYM1 datacenter

AppNexus currently runs two datacenters: LAX1 in Los Angeles and NYM1 in Secaucus, NJ. We feel that it is important to have multiple, geographically disparate datacenters that each functions as a self-contained entity with its own set of equipment.

Equinix

Equinix is the largest global network-neutral datacenter and Internet exchange services company in the world, with centers in 18 key markets across North America, Europe and Asia-Pacific and a total global footprint of more than 3 million square feet. More than 300 different carriers and ISPs now participate in Equinix IBX centers, including the world's largest IP backbone networks. Network and service provider customers include AT&T, British Telecom, MCI, Sprint, SBC, KDDI, and Level(3).

Floor Layout and Network Cabling

All racks are laid out in a hot/cold aisle configuration. This means that cold air is dropped down on the intake side of servers and exhausted out the back. This helps keep server temperatures low reducing failures and increasing hardware lifetime.
