AT&T today rebranded its Network Functions on Demand to AT&T FlexWare. The service is available to businesses globally through the broader AT&T Network on Demand platform.

In addition to the new name, AT&T is giving customers a new device option. Previously, the Network Functions on Demand service allowed businesses to use a single x86-based appliance to deploy up to four virtual network functions (VNFs) at locations in 76 different countries.

Now, AT&T FlexWare offers two device form factors — a smaller universal piece of equipment that can run up to two VNF applications and the previously available larger version that runs up to four VNFs. Also, AT&T says FlexWare is now available in more than 150 countries and territories.

With AT&T FlexWare, businesses can set up multiple VNFs, such as a router and a firewall, on a single FlexWare device and deploy them in different countries. And they can manage their network functions via an online portal.

Businesses can mix and match FlexWare devices and applications to address the needs of their various global locations. A smaller device for smaller offices would allow them to save some money on hardware.

"The smaller device creates more options for businesses that may not need four virtualized applications," said an AT&T spokesperson. Businesses can also start with one set of network functions and add as they go.

In addition to the new device, AT&T is adding Palo Alto Networks’ security platform to its catalog of VNFs. Palo Alto joins these previously announced VNFs:

• Juniper’s virtual router
• Cisco’s virtual router
• Fortinet’s virtual security
• Riverbed’s virtual WAN optimization.
