What AWS Cost Optimization Hub does#

Cost Optimization Hub is a feature of AWS Billing and Cost Management. It collects cost optimization recommendations from across your AWS accounts and Regions into one dashboard, so you don’t have to visit several AWS consoles to find them. Its recommendations cover resource rightsizing, idle resource deletion, Savings Plans and Reserved Instances.

Two things make it more useful than a raw list. First, its savings estimates take your own commercial terms with AWS into account, such as the Reserved Instances and Savings Plans you already hold. Second, it deduplicates overlapping recommendations, so savings are not counted twice. You can filter, sort and group the list, and track a cost efficiency metric over time.

It does not make changes. Each recommendation is something for your team to plan, test and carry out.

What AWS Compute Optimizer does#

Compute Optimizer analyses the configuration and CloudWatch utilisation metrics of your resources (the last 14 days by default, or 93 days with the paid enhanced infrastructure metrics option) and tells you whether each resource is over-provisioned, under-provisioned, idle or optimal. It covers EC2 instances, Auto Scaling groups, EBS volumes, Lambda functions, ECS services on Fargate, RDS and Aurora databases, NAT Gateways, DynamoDB, ElastiCache and several other services. Cost Optimization Hub takes its rightsizing and idle recommendations from Compute Optimizer.

Compute Optimizer now also has an Automation feature. Once you enable it, it can apply two kinds of recommended action: snapshotting and deleting EBS volumes that have been unattached for 32 days or more, and upgrading previous-generation EBS volume types (for example to gp3). You can apply these actions directly, or set rules that apply them on a daily, weekly or monthly schedule, and you can roll them back. The rest of its recommendations are still for your team to carry out.

What CloudFix does#

CloudFix connects to your AWS accounts in about 5 minutes, using read-only IAM roles deployed with CloudFormation for the scan. Its 110+ finders look across 30+ AWS services, and results are typically ready within 24 hours.

The difference is what happens next. 53 of the findings have automated fixers. When you approve a fix, it runs as an AWS Systems Manager Automation runbook in your own account, so the change is recorded in AWS’s own change tooling. Nothing runs until you approve it.

The catalogue reaches well past compute rightsizing. It includes fixes such as enabling S3 Intelligent-Tiering, setting CloudWatch log retention, turning on CloudFront compression, removing idle NAT Gateways and VPC endpoints, moving DynamoDB tables to Infrequent Access, moving Lambda functions and OpenSearch instances to Graviton, and retyping EBS gp2 volumes to gp3. CloudFix customers typically see 15–60% savings on each AWS service optimized, which adds up to 20–35% off the total bill.

When to choose Cost Optimization Hub and Compute Optimizer#

• You want AWS’s own view of your savings, at no extra cost, before you buy anything.
• Your team has the time to work through recommendations, test them and roll them out.
• Your main questions are about EC2, Auto Scaling or Lambda sizing, and about how many Savings Plans or Reserved Instances to buy.
• You only need unattached EBS volume cleanup and EBS volume-type upgrades to be automated, which Compute Optimizer’s Automation now handles.

When to choose CloudFix#

• Recommendations are piling up because nobody has time to act on them.
• You want fixes across more AWS services than the rightsizing and commitment set, such as S3, CloudWatch, CloudFront, VPC and DynamoDB.
• You want each change approved by a person and run as a Systems Manager runbook in your account.
• You want a savings figure you can take to finance: the average CloudFix customer finds 23% off the total bill.

Using them together#

These tools work well side by side. Keep Cost Optimization Hub and Compute Optimizer switched on: they are free, and their Savings Plan and Reserved Instance analysis covers rate questions that CloudFix leaves to RightSpend. CloudFix even includes a fixer that turns Compute Optimizer on in accounts where it is off, and another that enables enhanced EC2 metrics.

A practical split is to let the AWS tools size your commitments and let CloudFix apply fixes across the rest of your AWS services. If you already use Compute Optimizer’s Automation for EBS, keep it. CloudFix covers the services it doesn’t reach.
