Pricing & Support Flashcards
AWS Free Tier
The AWS Free Tier enables you to begin using certain services without having to worry about incurring costs for the specified period.
Three types of offers are available:
Always Free
12 Months Free
Trials
Always Free
These offers do not expire and are available to all AWS customers.
For example, AWS Lambda allows 1 million free requests and up to 3.2 million seconds of compute time per month. Amazon DynamoDB allows 25 GB of free storage per month.
12 Months Free
These offers are free for 12 months following your initial sign-up date to AWS.
Examples include specific amounts of Amazon S3 Standard Storage, thresholds for monthly hours of Amazon EC2 compute time, and amounts of Amazon CloudFront data transfer out.
Trials
Short-term free trial offers start from the date you activate a particular service. The length of each trial might vary by number of days or the amount of usage in the service.
For example, Amazon Inspector offers a 90-day free trial. Amazon Lightsail (a service that enables you to run virtual private servers) offers 750 free hours of usage over a 30-day period.
How AWS pricing works
AWS offers a range of cloud computing services with pay-as-you-go pricing.
Pay for what you use.
Pay less when you reserve.
Pay less with volume-based discounts when you use more.
Pay for what you use
For each service, you pay for exactly the amount of resources that you actually use, without requiring long-term contracts or complex licensing.
Pay less when you reserve
Some services offer reservation options that provide a significant discount compared to On-Demand Instance pricing.
For example, suppose that your company is using Amazon EC2 instances for a workload that needs to run continuously. You might choose to run this workload on Amazon EC2 Instance Savings Plans, because the plan allows you to save up to 72% over the equivalent On-Demand Instance capacity.
Pay less with volume-based discounts when you use more.
Some services offer tiered pricing, so the per-unit cost is incrementally lower with increased usage.
For example, the more Amazon S3 storage space you use, the less you pay for it per GB.
AWS Pricing Calculator
The AWS Pricing Calculator lets you explore AWS services and create an estimate for the cost of your use cases on AWS. You can organize your AWS estimates by groups that you define. A group can reflect how your company is organized, such as providing estimates by cost center.
When you have created an estimate, you can save it and generate a link to share it with others.
AWS LAMDA Pricing
For AWS Lambda, you are charged based on the number of requests for your functions and the time that it takes for them to run.
AWS Lambda allows 1 million free requests and up to 3.2 million seconds of compute time per month.
You can save on AWS Lambda costs by signing up for a Compute Savings Plan. A Compute Savings Plan offers lower compute costs in exchange for committing to a consistent amount of usage over a 1-year or 3-year term. This is an example of paying less when you reserve.
Amazon EC2 Pricing
With Amazon EC2, you pay for only the compute time that you use while your instances are running.
For some workloads, you can significantly reduce Amazon EC2 costs by using Spot Instances. For example, suppose that you are running a batch processing job that is able to withstand interruptions. Using a Spot Instance would provide you with up to 90% cost savings while still meeting the availability requirements of your workload.
S3 Pricing
For Amazon S3 pricing, consider the following cost components:
Storage - You pay for only the storage that you use. You are charged the rate to store objects in your Amazon S3 buckets based on your objects’ sizes, storage classes, and how long you have stored each object during the month.
Requests and data retrievals - You pay for requests made to your Amazon S3 objects and buckets. For example, suppose that you are storing photo files in Amazon S3 buckets and hosting them on a website. Every time a visitor requests the website that includes these photo files, this counts towards requests you must pay for.
Data transfer - There is no cost to transfer data between different Amazon S3 buckets or from Amazon S3 to other services within the same AWS Region. However, you pay for data that you transfer into and out of Amazon S3, with a few exceptions. There is no cost for data transferred into Amazon S3 from the internet or out to Amazon CloudFront. There is also no cost for data transferred out to an Amazon EC2 instance in the same AWS Region as the Amazon S3 bucket.
Management and replication - You pay for the storage management features that you have enabled on your account’s Amazon S3 buckets. These features include Amazon S3 inventory, analytics, and object tagging.

Consolidated billing
In an earlier module, you learned about AWS Organizations, a service that enables you to manage multiple AWS accounts from a central location. AWS Organizations also provides the option for consolidated billing.
The consolidated billing feature of AWS Organizations enables you to receive a single bill for all AWS accounts in your organization. By consolidating, you can easily track the combined costs of all the linked accounts in your organization. The default maximum number of accounts allowed for an organization is 4, but you can contact AWS Support to increase your quota, if needed.
Itemized Charges
On your monthly bill, you can review itemized charges incurred by each account. This enables you to have greater transparency into your organization’s accounts while still maintaining the convenience of receiving a single monthly bill.
