Billing, Pricing, and Support
What you will learn
In this domain, you will learn the AWS pay-as-you-go pricing model, the cost management tools (Cost Explorer, Budgets), the pricing options (On-Demand, Reserved Instances, Savings Plans, and Spot), and the structure of the support plans. At 12% it carries the smallest exam weight, but it is an area you cannot avoid in practice either.
Key points
- The basic AWS pricing model is pay-as-you-go - you pay only for what you use
- EC2 purchase options - On-Demand, Reserved Instances (RIs, discounted with a 1-year or 3-year commitment), Savings Plans (a discount in exchange for committing to an hourly spend amount), and Spot (up to 90% off, but subject to interruption)
- AWS Cost Explorer visualizes past cost trends, AWS Budgets alerts you when you exceed a budget, and AWS Pricing Calculator estimates costs in advance
- Consolidated Billing - combine the bills of multiple accounts into one with AWS Organizations and share volume discounts
- Trusted Advisor - checks best practices across categories such as cost optimization, performance, security, fault tolerance, service limits, and operational excellence
- Support plans - Basic Support is included with every account, and the paid tiers are Business Support+, Enterprise Support, and Unified Operations. The scope of technical support and the response times per issue severity differ across them (as of August 2026)
Terms and concepts
EC2 Pricing Options (On-Demand / RI / Savings Plans / Spot)
On-Demand is billed by the hour and is flexible, Reserved Instances (RIs) offer a discount in exchange for a 1-year or 3-year commitment, Savings Plans are more flexible than RIs because they commit to a usage amount, and Spot lets you use spare capacity at up to 90% off but may be interrupted. For long-term use, RIs / Savings Plans are candidates, while Spot is a candidate for interruptible batch workloads.

AWS Cost Explorer and AWS Budgets
Cost Explorer visualizes past costs and usage in graphs and lets you analyze them by service and by tag. Budgets lets you set a monthly budget and notifies you by email or SNS when you are about to exceed it. Cost Explorer is for looking back, while Budgets is for prevention, so their purposes differ.

Consolidated Billing and Organizations
Using the Consolidated Billing feature of AWS Organizations, you can combine the bills of multiple AWS accounts into one. Because volume discounts, such as those for S3, can be applied to the combined usage of all accounts, cost efficiency improves across the entire organization.
AWS Support Plans
Basic Support is included with every AWS account and covers billing and account inquiries as well as AWS Health event notifications, but it does not cover technical inquiries. The paid tiers are Business Support+, Enterprise Support, and Unified Operations. Business Support+ adds 24/7 technical support and responds within 1 hour when a production system is down. Enterprise Support adds a dedicated TAM (Technical Account Manager) and responds within 15 minutes when a business-critical system is down. Unified Operations further adds dedicated domain specialists and incident management engineers. As these examples show, the guaranteed response times are defined per issue severity. For production environments, Business Support+ or higher is common (plan lineup and response times as of August 2026).
AWS Trusted Advisor
A service that checks your AWS environment across the categories of cost optimization, performance, security, fault tolerance, and service limits, plus operational excellence, and offers recommendations for improvement. Basic Support provides only the core set of checks, while Business Support+ and above provide the full set (as of August 2026).
