Oracle said Monday that it has signed an agreement to acquire Dyn, a cloud-based Internet Performance and DNS provider.

Dyn’s solution is powered by a global network that drives 40 billion traffic optimization decisions daily for more than 3,500 enterprise customers, including preeminent digital brands such as Netflix, Twitter, Pfizer and CNBC.

The DNS provider was under siege last month from botnet-laden DDoS attacks that resulted in blackouts for certain users who could not access the platforms of some of the biggest sites on the internet utilizing Dyn’s services.

The attack on Dyn has led to greater scrutiny of internet of things devices by U.S. lawmakers, with calls for the implementation of cohesive regulations to guide the production of IoT devices.

Adding Dyn’s best-in-class DNS solution extends the Oracle cloud computing platform and provides enterprise customers with a one-stop shop for Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS), Oracle said.

“Oracle already offers enterprise-class IaaS and PaaS for companies building and running Internet applications and cloud services,” said Thomas Kurian, President, Product Development, Oracle. “Dyn’s immensely scalable and global DNS is a critical core component and a natural extension to our cloud computing platform.”

Dyn monitors, controls, and optimizes Internet applications and cloud services to deliver faster access, reduced page load times, and higher end-user satisfaction.
