Top 15+ AWS Cost Optimization Tools in 2024
With cloud spending making up a large and growing share of engineering budgets, cloud cost optimization is crucial to ensure cloud expenditures align with business objectives and budgets. Effective AWS cost optimization involves understanding billing and account structures, monitoring and visualizing real-time usage and costs, and making good decisions about resource allocation.
Everyone wants to save money in the cloud, and many tools are being marketed to help you do just that. Yet, it can be challenging to decide on the best solution. The right platform can help you cut through complexity and help you get more out of your cloud resources. On the other hand, selecting the wrong platform might lead to unpleasant billing surprises and missed savings.
That’s why we wrote this complete guide to AWS cost optimization tools — find out key areas of cost reduction, the best tools broken down by category, and strategies for reducing your AWS spending.
What is AWS Cost Optimization?
AWS cost optimization is the process of reducing your Amazon Web Services (AWS) expenses without sacrificing the performance and capacity requirements of your applications. It involves strategies such as selecting the right pricing model (such as On-Demand pricing versus Savings Plans), scaling resources to match demand, and utilizing tools and services designed to monitor, manage and reduce costs.
By optimizing AWS costs, businesses can ensure they are only paying for the resources they need, maximizing their return on AWS investments.
Best Practices for Reducing AWS Costs
Here are the key areas where almost any organization can reduce their AWS cloud costs.
#1: Cloud Management: Cost Allocation, Visibility & Reporting
Optimizing cloud costs often starts with addressing the key issue of limited visibility into expenses. Without clear insights, it’s hard to identify what and how much to cut. Key challenges typically include:
- The AWS bill is confusing, and it’s difficult to attribute shared costs
- It’s difficult to forecast spending and stay within the budget
- More visibility is needed to investigate unexpected charges or spikes in usage
The goal is to fully allocate, monitor, analyze and report cloud costs so that you fully understand how resources are being used and by whom. Key terms include:
- Cost allocation: the process of identifying and assigning the costs of shared cloud resources and services to different projects, applications, users or teams within an organization.
- Tags: simple metadata attached to resources in order to make them easily identifiable. If your AWS account has hundreds or thousands of resources, tags help you to categorize, filter and organize depending on different criteria such as project, environment or purpose.
Showbacks/Chargebacks: a type of cost allocation in which the costs of cloud services and resources are reported/billed to the business units or teams that use them.
#2: Commitment Management: Reserved Instances & Savings Plans
In exchange for a commitment to spend a certain amount, AWS will offer a substantial discount on compute resources (up to 72-75% depending on various factors such as the length and flexibility of the commitment). However, it’s not always easy to determine the right type or amount of commitment to make to save the most. If you under-commit, you miss out on discounts. But if you over-commit, you’re paying for resources you don’t need.
Forecasting costs and planning commitments is an art. There are many possible choices and combinations — for example, there might be over 200,000 pricing options for one particular type of compute in a single region. And as business needs determine cloud usage, it’s necessary to continually rebalance and re-optimize. Determining the right commitments to make requires often analyzing the past 30-45 days of historical data, which takes time.
For a comprehensive explanation and analysis of Savings Plans and Reserved Instances, how they are applied across your organization, and when to use them, you can check out The Ultimate Guide to AWS Commitments.
#3: AWS Spot Instance Optimization and Automation
AWS Spot Instances are spare AWS (On-Demand) capacity that users can purchase at a heavy discount. However, it’s important to note that AWS gives you a discount on the instance, but not a guarantee that you’ll be able to use it to the end of your compute need. The instance can be taken away at any time with a 2-minute warning, potentially disrupting critical workloads.
In addition, the Spot market is highly volatile. It is complex to manage fluctuating pricing, the types of instances available on the market, and the most cost-effective decision to make at any time, in view of existing commitments across your organization.
Luckily, tools can reduce much of the complexity involved in using Spot. By leveraging Machine Learning to analyze the market, your usage, and other dynamic factors, they can put you on the most reliable and cost-effective Spot options automatically.
#4: Cost Optimization Automation: Right Sizing & Scheduling
As your usage patterns evolve, you’ll find that some applications no longer need as many resources available to them as they once did. It’s essential to continually right size these applications so that you’re not overpaying for oversized or unnecessary instances. By analyzing historical usage and performance, you can identify and eliminate cloud waste and unnecessary spending.
Because continual right sizing is necessary to optimize costs, automation tools are key. Some features to look for include:
Right sizing recommendations for EC2 and Auto Scaling Groups
Scheduling capabilities to pause resources that are idle or not actively needed at certain times
Storage optimization & migration tools that can help you save time through automation

AWS Native Tools
Amazon Web Services offers many free tools to help with your AWS cloud cost optimization. Here are some of the most important:
#2: AWS Cost Explorer
AWS Cost Explorer enables you to view and analyze your costs and usage.
You can view data for up to the last 13 months, forecast how much you’re likely to spend for the next 12 months, and get recommendations for what Reserved Instances to purchase.
Cost Explorer can also be used to identify areas that need further inquiry and see trends that you can use to understand your costs.
#3: AWS Trusted Advisor
AWS Trusted Advisor helps you optimize costs, increase performance, improve security and resilience, and operate at scale in the cloud.
Trusted Advisor continuously evaluates your AWS environment using best practice checks across the categories of cost optimization, performance, resilience, security, operational excellence, and service limits, and recommends actions to remediate any deviations from best practices.
#4: AWS Budgets
With AWS Budgets, you can set custom budgets that trigger alerts when cost or usage exceed (or are forecasted to exceed) a budgeted amount. Budgets can be set based on tags and accounts as well as resource types. Major use cases include:
- Monitoring cost and usage — set your preferred budget period to daily, monthly, quarterly, or annually, and create specific budget limits.
- Creating scheduled reports — Stay informed on how actual or forecasted costs and usage progress toward your budget threshold.
- Responding to thresholds — Set up custom actions to run automatically or through an approval process when a budget target is exceeded.
#5: Amazon CloudWatch
Amazon CloudWatch is an AWS-native monitoring and observability service. It can be used to collect and track metrics, monitor log files, set alarms, and automatically react to changes in AWS resources.
Some of its most common uses include monitoring application performance, performing root cause analysis, optimizing resources, and testing website impacts.
#6: AWS Instance Scheduler
The AWS Instance Selector automates the starting and stopping of EC2 instances and RDS instances. You can stop resources that are not in use and start them back up as soon as you need them. This AWS tool functions by using resource tags and AWS Lambda to automatically stop and start instances, and it can be deployed across multiple AWS Regions based on a schedule you define.
When compared to a setup where you leave all your compute instances continuously running at full utilization (even when those resources aren’t being used), this solution can lead to significant cost savings.
