Calculate Savings

Adding Scheduler Labels:

CloudThrifty labels are used to instruct the Cloud Thrifty Scheduler of the time a repeat pattern to shutdown or startup a server operating system. You can add labels at anytime. Cloud Thrifty evaluated the project for changes every 45 minutes.

Label Key:
<action>-<pattern>-<hour_minute><am or pm>-<timezone>

Label Value:
*all label values are ignored by Cloud Thrifty. The gcp interface requires a value so you may use anything you like.

Stop - Everyday at 10:25 PM Eastern Standard Time

Start - Everyday at 10:25 PM Eastern Standard Time

Possible Options
  1. start - causes the server to boot up
  2. stop - causes the server to shutdown
Reccurance Pattern:
  1. m - every Monday
  2. t - every Tuesday
  3. w - every Wednesday
  4. th - every Thursday

  6. s - every Saturday
  7. su - every Sunday
  8. wd- weekdays (m,t,w,th,f)
  9. ed - every day (m,t,w,th,f,s,su)
  1. hour - the hour is 12 hour clock time
  2. underscore _ seperates the hour and the minute
  3. minute - minute of the hour for the action
  4. pm or am - time meridiem
Time Zone:
  1. est - Time zone representing the America/New_York time zone

Common Patterns
Business Hours:

This pattern is common in the dev and test space and in effect brings the servers online during working hours. Estimated savings 52% or more.


Weekend Savings:

This pattern is common when servers are just not needed on the weekends. Estimated savings 31% or more.


High Compute Cluster:

This pattern is common in retail and other industries to bring online clusters for high compute functions such as compiling machine learning models. This example is for a 12 hour workload on Saturdays.


Scenario Based

Developers create servers to debug crashdumps.  These servers require many gigs of RAM and high core counts.  These server are expensive and are often left running needlessly.


Add a Cloud Thrifty label to the GCP template or the automation system that creates the VM.  The following label added to the vm will cause it to shutdown every night at midnight.
