Excluding Certain Cloud Templates

Blog Post created by Ben Yemini Expert on Nov 19, 2017

In certain situations you may want to excluded EC2 instance or Azure Virtual Machine types from being recommended by Turbonomic for either real-time scaling actions or migration plans.  This may be due to an application team that prefers to only run on a certain size or an operational policy to only use a certain family.

 

Keep in mind that Turbonomic makes the best decisions to match your workload demand with the available templates across families and clouds so whenever you define these types of constraints you may be limiting the value Turbo can add in your environment.

 

That being said here is the approach:   

 

To exclude Globally, click on Settings> Policies> Default>Virtual Machine Default>Scroll down to Scaling Constraint and click ADD > select Excluded Templates (figure 1). 

 

Note in Turbonomic 6.1 you can also exclude templates for Databases on AWS or Azure.

From here you can add Templates to exclude by clicking on Add Template and then selecting the templates your want to exclude (figure 2).

To exclude for a group, for example if you want to exclude templates for a certain Region or a set of applications defined by tags,  click on Settings>Automation Policies> + Automation Policy (top right)>Virtual Machine>Scope (enter group name)> +Scaling Constraints>Add Scaling Constraint>Excluded Templates> Choose the templates you’d like to exclude (figure 3).

That's it, the policy now applies to both real-time scaling actions and migration plans.
