An AWS Pricing Primer
Before you start optimizing costs on Amazon, it’s important to understand the AWS pricing philosophy, and the tools Amazon gives you to optimize and save costs.
Amazon’s pricing model is based on three pillars. In the table below we briefly explain each of these principles, and what you should watch out for.
Amazon Pricing Pillar
How it Works
What You Should Watch Out For
Pay as You Go
AWS turns capital expenses in operating expenses by leasing computing resources, letting you pay for them by the hour.
Amazon’s on-demand pricing is quite expensive even for small workloads. Leverage “pay as you go” only for workloads that really have unexpected peaks or special scalability needs.
Pay Less by Using More
AWS gives you volume discounts for higher utilization of specific service features, and also when you spend more than $500,000 in upfront costs.
By increasing usage of AWS services, you also increase your lock-in to the Amazon ecosystem. Balance the desire for discounts with the need to maintain a healthy, multi-cloud strategy.
Save When You Reserve
Amazon EC2, which is the basis for most Amazon services, provides discounts of between 30-50% if you reserve instances 1-3 years in advance.
If you purchase reserved instances for a year or more at a time, seriously consider running the same workload on-premises. This will almost always be cheaper, unless there is a special need for the flexibility provided by the cloud.
AWS Cost Management Tools
Amazon provides a broad set of free tools for cost management and optimization. Familiarize yourself with these tools, and use them to gain data, make decisions, and create rules and automated actions that will help you save money on AWS.
Billing and Cost Management Console
The billing section of the Amazon Console lets you see what services you are consuming on AWS, and optimize their structure. Use tagging to organize services by project or department, and consolidate AWS accounts to create one billing entity for each project that has a separate budget within your organization. Read the official documentation on how to consolidate AWS billing accounts.
AWS Cost Explorer
The Cost Explorer interface lets you view usage, costs, and return on investment for Amazon services. It shows data for the past 13 months and helps you forecast future spend. Create customized views that can help you analyze your costs and identify areas for improvement. Cost Explorer also provides an API that lets you access the data via your analytics tools.

AWS Budgets lets you set and enforce budgets for specific Amazon services, and receive emails or messages from the Simple Notification Service (SNS) when budgets are reached or exceeded. You can specify an overall cost budget or connect the budget to specific data points, such as number of instances or data usage. The Budgets dashboard provides similar views to those of Cost Explorer, showing how services are being used compared to their budgets.
AWS Trusted Advisor
AWS Trusted Advisor is an automatic tool that provides guidance on best practices for your Amazon services. One of the five areas checked by Trusted Advisor is cost optimization. It provides automated optimization recommendations related to:
- EC2 reserved instance optimization and lease expiration
- Low utilization of EC2 instances
- Idle load balancers
- Underutilized EBS volumes
- Unassociated elastic IP addresses
- Idle DB instances on Amazon RDS
- Redundant Route 53 latency resource record sets
- Underutilized Amazon Redshift clusters
Amazon CloudWatch lets you set alarms based on a large variety of metrics captured from your Amazon services. CloudWatch is commonly used for cost optimization. For example, you can set up an alarm and notification when an EC2 instance’s utilization goes below 30%, investigate why the instance is underused, and take action to right-size the instance or combine workloads.
Five Best Practices for Reducing Your Amazon Bill
Now that you better understand Amazon’s pricing philosophy and the tools at your disposal for monitoring and optimizing costs, here are a few quick best practices that can help you substantially reduce your AWS bill.
- Rightsize instances—identify EC2 instances that are underutilized, and downgrade the instance size or move to a different instance family to save costs. For example, if you initially selected a Memory Optimized Instance, but you see your application is not as memory-intensive as expected, switch to a General Purpose instance.
- Delete zombie resources—one of the biggest drains on your AWS bill is continuing to run unused resources that are billed continuously, not per usage. A few examples are EBS volumes, obsolete snapshots, and unused Elastic IP addresses. Use AWS Trusted Advisor to get a list of most of these zombie resources and quickly knock them out.
- Instance scheduling—ideally, instances should only be started when actually used, but this may not be practical for many purposes. A common example is EC2 instances used for ongoing development and testing. These cannot be spawned on demand, but they should only be operational within the working hours of the relevant development team, and shut down when not actually used.
- Reserved instances and spot instances—the two major avenues for discounts on AWS are committing in advance to a reserved instance for 1-3 years, or using spot instances that may shut down unexpectedly, but shave up to 60% off costs. The trick is to carefully select workloads for which Reserved or Spot instances actually make sense, and avoiding using these options when they are not economical or practical.
- Move cold data to cheaper storage tiers—Amazon S3 offers several tiers for infrequently-accessed data—S3 Infrequent Access, S3 Glacier and S3 Deep Archive Glacier. Put automation in place to identify data when it is no longer needed for active production use, and move it to the cheapest cold storage tier. Cold storage can reduce storage costs per GB from $0.023 to as low as $0.00099.

AWS cost optimization is a broad topic. Different Amazon services have different pricing models and cost optimization techniques. Read the articles below to gain a deeper understanding of Amazon cost management strategies, with a special focus on storage services and opportunities for optimizing storage costs.
AWS Costs Overview
Amazon offers three pricing models that can generate major savings in your cloud bill: the Enterprise Discount Program (EDP), Reserved Instances, which allow you to pre-order compute resources from Amazon and get substantial discounts, and Spot Instances, which let you bid for spare capacity on the Amazon compute resources marketplace, and receive discounts of up to 90%.
Learn about these saving opportunities, and understand ten variations you are likely to see in your cloud bill compared to your estimates, including actual vs. projected usage, variance in service use, data transfer and throughput costs.

AWS Storage Costs
Amazon provides several popular cloud storage services: Elastic Block Store (EBS), Elastic File System (EFS), Simple Storage Service (S3), S3 Glacier, and more, each with its own pricing model and unique pricing parameters.
Understand storage costs across each of the primary storage services, and see Amazon storage pricing all in one place, with examples covering the most common scenarios.

Cloud Snapshot Costs
Cloud storage snapshots are point-in-time backups of storage volumes. Both AWS and Azure offer snapshot mechanisms, and while snapshots are very convenient, they can also become a large drain on your cloud bill. Each snapshot continues to live in cloud storage until you delete it, and costs can quickly add up.
Learn how snapshots work in AWS and Azure, understand snapshot costs on each platform, and manage your snapshots to ensure you are only paying for snapshots you actually need.
Controlling EBS Costs
Amazon EBS provides persistent storage for Amazon EC2 instances. However, when you shut down an EC2 instances, the EBS storage volume may be not automatically deleted. This can lead to major cost overages, for example in case you deploy auto scaling and automatically create largen numbers of EC2 instances, but forget to erase their attached EBS volumes when they are no longer needed.
Learn how to find unused EBS volumes and automatically delete them using an AWS Lambda function, to control EBS costs and avoid waste.
