Wireless network operator Verizon Communications Inc. has become the latest big enterprise to move a large chunk of its business applications to Amazon Web Services Inc., choosing the company as its “preferred public cloud provider.”

Verizon, which been working with AWS since 2015, said it’s planning to migrate more than 1,000 business-critical applications and database backend systems to AWS. The company is also planning to migrate a number of production databases to Amazon’s Aurora service, which is a relational database engine that was built to rival legacy systems such as Oracle Corp.’s 12c database.

Verizon said the move is designed to help it increase its agility and lower costs by becoming more reliant Amazon’s cloud computing infrastructure instead of operating its own. As part of the initiative, Verizon will also build a number of AWS-specific training facilities called “dojos,” where its employees will be able to get up to speed on the cloud provider’s technologies and systems.

“We are making the public cloud a core part of our digital transformation, upgrading our database management approach to replace our proprietary solutions with Amazon Aurora,” said Mahmoud El-Assir, senior vice president of global technology services at Verizon.

Verizon’s announcement comes less than a week after the Ireland-based low-cost airline Ryanair DAC said that it too was going “all-in” on Amazon’s cloud. Ryanair said at the time it was standardizing on AWS services, including AWS databases, analytics, machine learning and deep learning services.

The airline already has a number of interesting projects on the go using Amazon’s cloud infrastructure. For one thing, the company said, it’s building a companywide data lake on Amazon S3, using the Amazon Kinesis service to gain better insights from its customer and business data. In addition, Ryanair is also working with Amazon’s machine learning solutions lab to build software that can help it to predict surges in flight demand.

Amazon has scored several big customer already in 2018. Prior to Ryanair, AWS landed Oath Inc., a subsidiary of Verizon Communications Inc. that includes Yahoo and AOL brands, as another of its marquee customers. It also signed on the image publishing service Shutterfly Inc. and vehicle services firm Cox Automotive Inc. in April, web-hosting firm GoDaddy Inc. in March, and Comcast Cable in January.
