Cloud spend is anticipated to continue its massive growth trajectory for the foreseeable future. However, the spend does not have to match that same growth curve! To help our Clients maintain sound Cloud Optimization programs, we've assembled a series of articles and tips called: 12 for '21 Cloud Optimization Series (note: request a download of all 21 here).
Today we review the fourth installment in the series: Power-Cycle It.
A large portion of the cloud waste originates from idle and low utilization instances. This is particularly relevant for non-production (e.g. development, testing, QA, etc.) instances and applications with consumption that may spike frequently (e.g. analytics) . In this type of environment, instances are not active 24/7, rather consumption occurs for short time periods of the day or week. You should take advantage of stopping these instances when unused and activate them only during periods of activity. Simply by turning them off during these ‘inactive’ periods can save 65% of the cost.
Understand your consumption.
Using native cost tools (e.g. AWS cost explorer, Azure advisor), you should review and validate compute consumption patterns for all applications and environments. This is a critical step toward identification of instances that might be ‘on’ with little or no consumption for prolonged periods and at regular intervals.
Develop steps toward management of instances.
Once you have identified your set of idle and low utilization instances, you can take your first steps toward optimization:
- Terminate* idle instances or the ones used sporadically for non-production testing and QA.
- Stop low utilization instances where you have identified inactive periods at defined time intervals
You should automate the stopping of instances with the ‘scheduler’ features of your cloud provider (e.g. AWS instance scheduler, Azure Automation or Google scheduler). A scheduler ensures that instances are stopped at specific periods, so you aren’t charged for compute time not actually used.
