How has OpenStack transformed your business?

AT&T is a legacy telco which is transforming itself by adopting virtual infrastructure and a software defined networking focus in order to compete in the market and create value for customers in the next five years and beyond.

  1. Virtualization and virtual network functions (VNFs) are of critical importance to the Telecom industry to address growth and agility. AT&T’s Domain 2.0 Industry Whitepaper released in 2013 outlines the need as well as direction.
  2. AT&T chose OpenStack as the core foundation of their cloud and virtualization strategy
  3. OpenStack has reinforced AT&T’s open source strategy and strengthened our dedication to the community as we actively promote and invest resources in OpenStack
  4. AT&T is committing staff and resources to drive the vision and innovation in the OpenStack and OPNFV communities to help drive OpenStack as the default cloud orchestrator for the Telecom industry
  5. AT&T as a founding member of the ETSI ISG network functions virtualization (NFV) helped drive OpenStack as the cloud orchestrator in the NFV platform framework. OpenStack was positioned as the VIM – Virtual Infrastructure Manager. This accelerated the convergence of the Telco industry onto OpenStack.

OpenStack serves as a critical foundation for AT&T’s software-defined networking (SDN) and NFV future and we take pride in the following:

  • AT&T has deployed 70+ OpenStack (Juno & Kilo based) clouds globally, which are currently operational. Of the 70+ clouds 57 are production application and network clouds.
  • AT&T plans 90% growth, going to 100+ production application and network clouds by the end of 2016.
  • AT&T connects more than 14 million wireless customers via virtualized networks, with significant subscriber cut-over planned again in 2016
  • AT&T controls 5.7% of our network resources (29 Telco production grade VNFs) with OpenStack, with plans to reach 30% by the end of 2016 and 75% by 2020.
  • AT&T trained more than 100 staff in OpenStack in 2015

AT&T plans to expand to expand its community team of 50+ employees in 2016 As the chosen cloud platform OpenStack enabled AT&T in the following SDN and NFV related initiatives:

  • Our recently announced 5G field trials in Austin
  • Re-launch of unlimited data to mobility customers
  • Launch of AT&T Collaborate a next generation communication tool for enterprise
  • Provisioning of a Network on Demand platform to more than 500 enterprise customers
  • Connected Car and MVNO (Mobile Virtual Network Operator)
  • Mobile Call Recording
  • Internally we are virtualizing our control services like DNS, NAT, NTP, DHCP, radius, firewalls, load balancers and probes for fault and performance management.

Since 2012, AT&T has developed all of our significant new applications in a cloud native fashion hosted on OpenStack. We also architected OpenStack to support legacy apps.

  • AT&T’s SilverLining Cloud (predecessor to AIC) leveraged the OpenStack Diablo release, dating as far back as 2011
  • OpenStack currently resides on over 15,000 VMs worldwide, with the expectation of further, significant growth coming in 2016-17
  • AT&T’s OpenStack integrated Orchestration framework has resulted in a 75% reduction in turnaround time for requests for virtual resources
  • AT&T Plans to move 80% of our Legacy IT into the OpenStack based virtualized cloud environment within coming years
  • Uniform set of APIs exposed by OpenStack allows AT&T business units to leverage a "develop-once-run-everywhere" set of tools OpenStack helps AT&T’s strategy to begin to adopt best of the breed solutions at five 9’s of reliability for:
    • NFV
    • Internet-scale storage service
    • SDN
  • Putting all AT&T’s workloads on one common platform Deployment Automation: OpenStack modules have enabled AT&T to cost-effectively manage the OpenStack configuration in an automated, holistic fashion.
  • Using OpenStack Heat, AT&T pushed rolling updates and incremental changes across 70+ OpenStack clouds. Doing it manually would be take many more people and a much longer schedule.
  • Using OpenStack Fuel as a pivotal component in its cloud deployments AT&T accelerates the otherwise consuming, complex, and error-prone process of deploying, testing, and maintaining various configuration flavors of OpenStack at scale. AT&T was a major contributor towards Fuel 7.0 and Fuel 8.0 requirements. OpenStack has been a pivotal driver of AT&T’s overall culture shift. AT&T as an organization is in the midst of a massive culture shift from a Legacy Telco to a company where new skills, techniques and solutions are embraced.

OpenStack has been a key driver of this transformation in the following ways:

  • AT&T is now building 50 percent of all software on open source technologies
  • Allowing for the adoption of a dev ops model that creates a more unified team working towards a better end product
  • Development transitioned from a waterfall to cloud-native CICD methodologies
  • Developers continue to support OpenStack and make their applications cloud-native whenever possible.

How has the organization participated in or contributed to the OpenStack community?

AT&T was the first U.S. telecom service provider to sign up for and adopt the then early stage NASA-spawned OpenStack cloud initiative, back in 2011.

  • AT&T has been an active OpenStack contributor since the Bexar release.
