AWS Compute Optimizer
💡 Definition
AWS Compute Optimizer is a service that analyzes the configuration and utilization metrics of your AWS resources. It reports whether your resources are optimal and generates recommendations to reduce costs and improve performance by rightsizing your workloads.
🔑 Key Concepts
- Rightsizing: The process of matching instance types and sizes to your workload performance and capacity requirements at the lowest possible cost.
- Machine Learning: Uses machine learning to analyze historical utilization data from CloudWatch.
- Recommendations: Suggests optimal AWS resources for your workloads to reduce costs and improve performance. Supports EC2 instances, Auto Scaling groups, EBS volumes, and Lambda functions.
- Finding Status: Classifies resources as Under-provisioned, Over-provisioned, or Optimized.
⚙️ How it Works
- Opt-In: You enable Compute Optimizer in the console.
- Analysis: The service analyzes at least 30 hours of historical CloudWatch metrics for your resources.
- Dashboard: It presents recommendations in a dashboard, showing potential cost savings or performance improvements.
🎯 Use Cases
- Cost Reduction: Identifying over-provisioned (too large) instances and recommending smaller, cheaper alternatives.
- Performance Improvement: Finding under-provisioned (too small) instances that may be throttling and recommending larger ones.
- EBS Optimization: Recommending changes to EBS volume type or size.
💰 Pricing Model
- Free: AWS Compute Optimizer is a free service.
