Google Implements NFV, SDN as Part of Its Andromeda Effort

By Paula Bernier April 22, 2014

Google this month announced that the Andromeda network virtualization stack is now available on two Google Compute Engine zones, and that it’ll be migrating the others to Andromeda in the near future. The current Andromeda zones include us-central1-b and europe-west1-a.

Amin Vahdat, Google distinguished engineer, in a blog explained that Andromeda is a software-defined networking substrate being leveraged to support Google’s network virtualization efforts.

“It is the orchestration point for provisioning, configuring, and managing virtual networks and in-network packet processing,” writes Vahdat.

The goal of Andromeda is to expose the raw performance of the network and exposing NFV in an effort to allow for scaling. That allows for access control lists, distributed denial of service protection, firewalls, and transparent service load balancing.

Vahdat adds that Andromeda is not a cloud platform, but is rather the basis for delivering cloud platform networking services with high availability, isolation, performance, and security.

“For example,” Vahdat writes, “Cloud Platform firewalls, routing, and forwarding rules all leverage the underlying internal Andromeda APIs and infrastructure.”

While Google is clearly a pioneer in the NFV and SDN arenas, many of the large, long-time telephone and broadband network operators also appear to poised to adopt these technologies.

As previously reported by NFVZone, buying decisions at facilities-based service providers are being driven by strategic goals and high-level individuals at these organizations, but cost remains the primary driver, according to new survey results just released by Current Analysis. The firm says the CTO office is primarily responsible for making SDN/NFV evaluation and purchase decisions. CTOs, according to those surveyed, drive decisions around the deployment of NFV and SDN technologies nearly 70 percent of the time. CIOs also are becoming increasingly relevant in this decision-making process, according to the survey.

Cost savings are driving interest in NFV and/or SDN, according to about two-thirds of survey respondents. Opex savings are the leading driver, according to the largest segment of those surveyed, while new revenue generation, and capital expense savings rank second and third as key drivers of NFV and/or SDN, according to the survey.
