Oracle is buying Dyn, the internet infrastructure outfit whose A-list customers were struck by a global DDoS from internet-attached "things" in October.
The software giant is buying Dynamic Network Services (Dyn) to speed up cloud computing traffic. Financial terms were not disclosed
Dyn's platform controls and optimises applications and infrastructure through using analytics and routing..
Customers of the 15-year-old firm include Twitter, PayPal and Spotify.
It was these firms, along with others, who were on the receiving end of a global DDoS attack coming from hundreds of thousands of IoT devices in October.
Dyn said at the time that its data centres were being slammed with 40-50 times the normal incoming traffic from tens of millions of web addresses around the plant.
That meant traffic from such normally innocuous devices as webcams.
A "significant volume" of attack traffic came from botnets using Mirai, malware that targets Linux-based systems.
The attacks, Dyn said, "highlighted vulnerabilities in the security of 'Internet of Things' devices that need to be addressed".
Big Red did not acknowledge the attack in announcing the purchase.
Thomas Kurian, Oracle president of product development, said in a short statement: "Dyn's immensely scalable and global DNS is a critical core component and a natural extension to our cloud computing platform."
The deal potentially equals DNS routing and traffic performance capabilities found in Amazon's AWS and on Microsoft's Azure – Route 53 and Azure DNS. ®
