Oracle scored a cloud deal with AT&T that will move thousands of the telecommunication operator’s internal databases to the Oracle Cloud Infrastructure-as-a-Service (IaaS) and the Platform-as-a-Service (PaaS).

Oracle said the deal includes the migration of thousands of existing Oracle databases and associated applications to Oracle Cloud. The move is set to provide AT&T with access to those assets via Oracle’s public cloud platform and its own Integrated Cloud, and provide AT&T enterprise customers with more access choices.

AT&T also plans to deploy Oracle’s Field Service Cloud in conjunction with its own machine learning and big data platforms to customers as a scheduling and dispatch option. AT&T said the platform could reach more than 70,000 field technicians.

Financial details were not released, but Oracle appeared over-the-moon on the news, with CEO Mark Hurd gushing “this is a historic agreement” in a statement.

Oracle last month bolstered its Data Cloud platform with the acquisition of advertising analytics startup Moat. The company works with publishers and advertisers to track and measure online ads, and counts customers in ESPN, Facebook, Nestle, Procter & Gamble, Snapchat, Unilever, and YouTube. Moat is set to remain an independent platform within Oracle Data Cloud.

John Donovan, chief strategy officer and group president of AT&T’s Technology and Operations division, linked the move to the carrier’s Network 3.0 Indigo initiative, which it announced earlier this year. Indigo 3.0 taps the carrier’s network virtualization moves around software-defined networking (SDN), network functions virtualization (NFV), and cloud technologies in support of its planned 5G technology deployment. AT&T has said it plans to have 55 percent of its network functionality converted to SDN control by year end, having hit 34 percent at the end of 2016, and with plans to hit 75 percent control by 2020.

As for its cloud efforts, AT&T last October announced a deal with IBM to tap the carrier’s FlexWare platform to support the set-up and running of virtual network functions (VNFs) for services sold to clients and for its own internal operations. AT&T in turn said it will look to run applications on IBM’s cloud, cognitive, analytics, and security infrastructure.

AT&T in late 2015 announced plans to transition its managed application and hosting services unit to IBM as well as offload equipment and access to floor space in AT&T data centers supporting those operations. The deal called for IBM to include the AT&T services into its IBM Cloud portfolio targeted at offering enterprise customers a broader suite of networking, application, and hosting services. As part of the deal, AT&T said it would continue to provide networking services, including security, cloud networking, and mobility, and that it would work with IBM to provide integrated solutions to customers.
