Nicole Rodriguez, VP and CTO of AT&T Mexico, remarked on the growing importance of automation and called cloud networking the "Holy Grail." "It starts with virtualization, working network functions from the on premise cloud. Now the challenge is the public cloud, and how to put network flows into the public cloud. What we are doing is creating a path where we are testing and sensing how the maturity of the technology is moving. Many providers are creating their applications and, on the other hand, the telco cloud is under development," he commented.
