OpenStack Operators Detail How They Patched for Meltdown, Spectre

May 30, 2018 / Sean Michael Kerner

When the Meltdown and Spectre CPU security vulnerabilities were publicly disclosed on Jan. 3, they set off a flurry of activity among IT users and cloud operators around the world. In a panel moderated by eWEEK at the OpenStack Summit in Vancouver, B.C., on May 24, operators detailed how they dealt with patching for Meltdown and why it was a time-consuming process. When it comes to OpenStack, no operator in the world is larger than CERN, home of the Large Hadron Collider (LHC) and an OpenStack cloud infrastructure that has approximately 300,000 compute cores. Arne Wiebalck is responsible for the overall operations of CERN's OpenStack cloud, and when vulnerabilities like Meltdown and Spectre appear, it's his responsibility to react and deploy the corresponding fixes.
