Opportunity Name:
EMR Enable Managed Scaling
AWS Resource Type:
EMR (Elastic MapReduce)
Opportunity Description:
Amazon EMR clusters can benefit from cost optimization by enabling managed scaling. Managed scaling automatically resizes your cluster for best performance at the lowest possible cost. This finder identifies EMR clusters where managed scaling could be enabled to optimize costs, focusing on clusters using Task instances.
Criteria for identifying the opportunity:
- Checks if the EMR cluster exists.
- Verifies that the cluster is not already using managed scaling with a minimum capacity of more than one.
- Ensures the cluster version is compatible with managed scaling. Compatible versions are 5.30.2, 5.31.1, 5.32.1, 5.33.1 and higher, and 6.x releases 6.1.1, 6.2.1, 6.3.1 and higher.
- Annual cost, extrapolated from the last 31 days of usage, exceeds the annual public cost threshold (default $100).
- Estimated savings are greater than 2% of the annual cost.
Potential savings (range in % on annual basis):
- Savings are calculated based on the average active hours per day of Task instances in the cluster over the last 30 days. The formula used is: annualCost x averageActiveHoursPerDay / 24.
- Actual savings will depend on the specific usage patterns and configurations of the identified EMR clusters.
Can CloudFix apply an automatic fix?
No
Other considerations:
- Performance impact: Enabling managed scaling can lead to better resource utilization and potentially improved performance during peak processing times.
- Data loss considerations: There is no direct impact on data from enabling managed scaling. However, it's essential to monitor the cluster's performance and scaling events to ensure processing completes successfully.
- Security concerns: No direct security concerns with enabling managed scaling. Ensure that your cluster's security configurations, such as network and access controls, remain consistent with your organization's policies.
