Explanation
AWS Compute Optimizer is the correct service for rightsizing EC2 instances because:
-
Purpose: AWS Compute Optimizer analyzes the configuration and resource utilization of your EC2 instances to identify optimal instance types based on your workload patterns
-
Rightsizing: It specifically helps identify when instances are over-provisioned (low usage) or under-provisioned (high usage) and recommends appropriate instance types
-
Cost Optimization: By recommending the right-sized instances, it helps reduce costs while maintaining performance
-
Alternative services:
-
AWS Config: Used for compliance auditing and resource configuration tracking
-
AWS Cost Anomaly Detection: Identifies unusual spending patterns
-
AWS Budgets: Sets spending limits and alerts for cost management
-
When EC2 instances have low usage, Compute Optimizer can recommend smaller instance types or different instance families that better match the actual workload requirements, leading to significant cost savings.
