CenturyLink Cloud offers customers Hyperscale Servers – an instance type that is designed for distributed workloads that require maximum performance. Hyperscale offers the same top-tier CPU and RAM performance found in our standard servers – and adds 100% flash storage. That means customers can typically expect at least 15,000 IOPS to turbo-charge applications.
Anti-affinity policies make it possible to spread workloads across physical hosts. When a new server is created and references an anti-affinity policy, the CenturyLink Cloud platform makes sure that all the virtual servers in that policy are distributed to unique physical hosts.
Prerequisites to Leverage Anti-Affinity Policies
- A Hyperscale enabled Data Center. Refer to the Centurylink Cloud Feature Availability Matrix for a list of Cloud locations that support Hyperscale
- A Hyperscale Virtual Machine. Customers can only apply Anti-Affinity Policies to Hyperscale Virtual Machines. Standard Virtual Machines are not supported at this time.
Creating an Anti-Affinity Policy
In the left navigation pane click on Infrastructure > Policies > Hypsercale Anti-Affinity
Select Create Anti-Affinity Policy. Input a name for the Policy and choose a Hyperscale Enabled Data Center. Anti-Affinity Policies are Data Center specific. Once done select the create button.
Creating a Virtual Machine with an Anti-Affinity Policy
Create a new Hyperscale virtual server in CenturyLink Cloud. When doing so the ability to choose an Anti-Affinity policy will be available. Select the policy you wish to leverage.
Adding an Existing Virtual Machine to an Anti-Affinity Policy
Navigate to the Hyperscale Virtual Machine in the Servers portion of control. In the Server Info portion of the page select apply and choose the Anti-Affinity Policy you wish this VM to leverage.
