What is AWS Compute Optimizer?

AWS Compute Optimizer is a cutting-edge service designed to refine and enhance your AWS resource usage. It scrutinizes your AWS resources, evaluating their configurations against utilization metrics to determine optimal performance. These insights facilitate evaluating which recommendation strikes the perfect balance between price and performance, guiding you on when to adjust your running resources to satisfy your performance and capacity requisites seamlessly.

This article will help you understand how AWS Compute Optimizer works, how it’s priced, what resources are supported, and how to get started with using it.

How does AWS Compute Optimizer reduce costs?

AWS Compute Optimizer’s foundation is built on a robust analysis of the configuration and utilization metrics of your resources, sourced from Amazon CloudWatch over the preceding 14 days. This encompasses a comprehensive examination of specifications such as vCPUs, memory, storage, alongside utilization metrics like CPU usage, network activity, and disk operations for currently active instances.

AWS Compute Optimizer, How it works,

By tapping into this wealth of data, Compute Optimizer leverages machine learning to pinpoint patterns and discern the optimal resources for your specific workload, offering recommendations that ensure your resources are neither over-provisioned—leading to unnecessary expenditure—nor under-provisioned—resulting in performance bottlenecks.


AWS Compute Optimizer Supported Services List

AWS Compute Optimizer extends its capabilities across a broad spectrum of services, offering tailored recommendations to enhance resource efficiency and performance. Here’s a detailed look at the supported resources and the specific requirements for each to qualify for optimization recommendations:

  • Amazon Elastic Compute Cloud (Amazon EC2) Instances: Compute Optimizer analyzes EC2 instances, providing suggestions for resizing or changing instance types based on utilization metrics. It’s essential that these instances accumulate a minimum of 30 to 60 hours of CloudWatch metric data for accurate analysis.
  • Amazon EC2 Auto Scaling Groups: Recommendations for Auto Scaling groups aim at optimizing the performance and cost of the collection of EC2 instances they manage. These recommendations consider the aggregated metrics of all instances within the group, ensuring the Auto Scaling group’s configuration aligns with demand.
  • Amazon Elastic Block Store (Amazon EBS) Volumes: Compute Optimizer assesses EBS volumes’ performance and suggests modifications in volume type or size to better meet storage workload demands while optimizing costs.
  • AWS Lambda Functions: For serverless architectures, it provides insights into function configurations, suggesting adjustments in memory allocation and execution time settings to improve efficiency and reduce execution costs.
  • Amazon Elastic Container Service (Amazon ECS) Services on AWS Fargate: It evaluates ECS services running on the Fargate launch type, offering recommendations to adjust CPU and memory configurations to match the service’s requirements closely.
  • Commercial Software Licenses: Beyond AWS-specific resources, Compute Optimizer also advises on the optimization of commercial software licenses deployed on AWS infrastructure, potentially reducing licensing costs.

Additional Limitations in Compute Optimizer

Metric Requirements and Limitations: For Compute Optimizer to generate actionable recommendations, resources must meet specific metric data accumulation requirements — typically requiring 30 to 60 consecutive hours of metric data. This ensures that the analysis, which could take up to 12 hours to complete, is based on substantial usage patterns for reliability.

Instance Type Limitations: While Compute Optimizer supports a wide range of EC2 instance types, it notably does not generate recommendations for -g instance types. Recommendations are primarily focused on M, C, R, T, and X instance types, enabling broad coverage across compute-intensive and memory-intensive applications. However, if an EC2 Auto Scaling group contains both supported and unsupported instance types, the service will only generate recommendations for the supported types.

AWS Compute Optimizer use cases and examples

AWS Compute Optimizer’s capabilities are pivotal across diverse scenarios, demonstrating its essential role in optimizing cloud deployments efficiently and cost-effectively:

Tailored Rightsizing: It allows for the fine-tuning of EC2 and Auto Scaling instances to precisely meet the demands of specific workloads. For instance, it can scale resources down during low-traffic periods for a blog site, avoiding unnecessary costs, or scale up during high-demand periods for a retail website during sales events, ensuring customer satisfaction without overspending.

Accurate Recommendations: By enabling CloudWatch metrics, AWS Compute Optimizer delves into usage data to provide more accurate optimization suggestions. This could mean identifying over-provisioned instances based on actual usage patterns for a software development environment, leading to recommendations for downsizing that can result in significant savings.

License Cost Optimization: This feature automates the identification of cost-saving opportunities for software licenses. For example, it could suggest more cost-effective licensing configurations for database servers running on EC2 instances, which could drastically reduce licensing fees without impacting performance.

Effortless Migrations to AWS Graviton CPUs: AWS Compute Optimizer identifies EC2 workloads that would benefit from migrating to AWS Graviton CPUs, which are known for their price-performance advantages. For high-compute workloads like machine learning inference or video processing, this could translate into substantial savings while gaining processing efficiency.


AWS Compute Optimizer Pricing Tiers

Compute Optimizer Free Usage Limit

The default version of AWS Compute Optimizer is available at no additional charge. This version analyzes your Amazon CloudWatch metrics for the past 14 days to provide optimization recommendations for Amazon EC2 instances, Amazon ECS services on AWS Fargate, Amazon EBS volumes, and AWS Lambda.

You are only responsible for the costs of the resources you use to run your applications and for any Amazon CloudWatch monitoring fees. This makes AWS Compute Optimizer an invaluable tool for organizations looking to optimize their AWS resource usage without incurring additional costs.

Compute Optimizer Enhanced Infrastructure Metrics Pricing & Costs

For those requiring deeper insights, AWS Compute Optimizer offers the enhanced infrastructure metrics feature. This paid feature extends the CloudWatch metrics analysis period from 14 days to up to three months, capturing more comprehensive utilization patterns.

The cost for enhanced infrastructure metrics is $0.0003360215 per resource per hour, based on the number of hours the resource is running each month. This equates to approximately $0.25 per resource for a full 31-day month.

Pricing Examples

Example 1: Activating enhanced infrastructure metrics for five EC2 instances running 744 hours (31 days) in July results in a charge of $1.25.

Example 2: For a fixed-size Auto Scaling group with five distinct EC2 instances (three running 744 hours and two running 372 hours), the total charge for July is $1.00.

Example 3: Activating enhanced infrastructure metrics for five EC2 instances running 360 hours (15 days) in June leads to a charge of approximately $0.6048387.

These examples illustrate how AWS Compute Optimizer’s enhanced infrastructure metrics feature can provide more detailed recommendations for a modest fee, enabling more significant savings and performance improvements over time
