4.1
Task Statement

AWS Pricing Models

On-Demand · Reserved · Spot · Savings Plans · Free Tier

Task 4.1 — EC2 Pricing

EC2 Instance Purchasing Options

On-Demand
Pay by the hour or second, no commitment. Most flexible — start and stop anytime.
No savings discount
Use for: unpredictable workloads, short-term needs, testing/development.
Reserved Instances (RIs)
1-year or 3-year commitment for a specific instance type in a Region.
Up to 72% savings vs On-Demand
Use for: steady-state, predictable workloads. Standard RI = highest savings, least flexible.
Spot Instances
Bid on unused EC2 capacity. AWS can reclaim with 2-minute notice.
Up to 90% savings vs On-Demand
Use for: fault-tolerant, stateless, interruptible workloads (batch jobs, big data).
Savings Plans
Commit to a consistent amount of compute usage ($/hour) for 1 or 3 years. More flexible than RIs — applies across instance families and Regions.
Up to 66% savings vs On-Demand
Use for: predictable workloads where flexibility across instance types is needed.
Dedicated Hosts
Physical server dedicated to your use. Required for strict compliance or per-socket/per-core licensing (BYOL for Windows Server).
Most expensive option
Use for: regulatory requirements, software licenses tied to physical cores.
AWS Free Tier
Three types: Always Free (e.g., Lambda 1M requests/month), 12 Months Free (EC2 t2.micro 750 hrs/month), Short-term Trial (specific services).
$0 within limits
Use for: learning, prototyping, new account exploration.

Task 4.1 — General Pricing

AWS Pricing Principles & Tools

Three Fundamentals of AWS Pricing
  • Compute — pay for the compute time you use (EC2 hours, Lambda requests)
  • Storage — pay for data stored (S3 GB-month, EBS GB-month)
  • Data transfer — inbound data is FREE; outbound data transfer OUT of AWS to the internet incurs a charge
Data Transfer Rules
  • Inbound to AWS — always FREE
  • Between services in the same Region — often FREE or very low cost
  • Outbound to internet — charged (varies by Region)
  • Cross-Region transfer — charged
AWS Pricing Calculator

Free web tool to estimate monthly costs before deploying. Build a model of your architecture and get a cost estimate by service. Share estimates via a URL.

Use for: pre-migration cost analysis, architecture trade-off comparison.

S3 Pricing Factors
  • Storage amount (GB per month per class)
  • Number of requests (GET, PUT, LIST)
  • Data transfer out
  • Management features (lifecycle, replication)
⚡ Exam Note: Outbound data transfer to the internet costs money — inbound does NOT. This is a common exam question. Using CloudFront as a CDN can reduce data transfer costs from S3.

Task Statement

Billing & Cost
Management Tools

Cost Explorer · Budgets · CUR · Organizations · Compute Optimizer

Task 4.2 — Billing Tools

AWS Cost Management Services

AWS Billing DashboardMain billing console page. View current month charges, invoices, payment methods, and cost breakdown by service.
AWS Cost ExplorerVisualize and analyze cost and usage over time. View trends, filter by service/account/tag. 12 months of historical data + 12-month forecasts.
AWS BudgetsSet custom cost, usage, or reservation budgets. Receive alerts when spending approaches or exceeds thresholds. Proactive cost control.
AWS Cost and Usage Report (CUR)Most granular billing data available. CSV reports delivered to S3. Line-item detail of every AWS charge. Used for detailed analysis or feeding into Athena/Redshift.
AWS Compute OptimizerAnalyzes EC2, Lambda, and ECS usage patterns and recommends right-sized resources. Identifies over-provisioned instances to reduce cost.
AWS OrganizationsManage multiple AWS accounts centrally. Consolidated billing — combine usage across accounts to reach volume discount tiers faster.
Cost Allocation TagsTag AWS resources (e.g., Project=Marketing). Use tags in Cost Explorer to break down costs by team, project, environment, or department.

Task 4.2 — AWS Organizations

Consolidated Billing & AWS Organizations

AWS Organizations

Centrally manage multiple AWS accounts under a single root organization. Create Organizational Units (OUs) to group accounts by team, department, or environment.

  • Apply Service Control Policies (SCPs) to restrict what accounts can do
  • Consolidated billing — one bill for all accounts
  • Share Reserved Instances across accounts
Service Control Policies (SCPs)

Guardrails applied to OUs or individual accounts within an Organization. They limit what actions can be taken — even by root users within member accounts.

Example: "No account in the Dev OU can launch instances larger than t3.medium."

Consolidated Billing Benefits
  • One bill — all accounts, single monthly invoice to the management account
  • Volume discounts — combine usage across accounts to reach higher discount tiers (S3, data transfer)
  • RI sharing — unused Reserved Instances in one account automatically apply to other accounts in the org
  • Free of charge — consolidated billing itself has no additional cost
⚡ Exam Note: Consolidated billing is one of the primary benefits of AWS Organizations for cost management. Combined usage = higher volume discounts. One scenario: a company with 10 accounts pays less per GB of S3 than each account paying separately.

Task 4.3 — Support Tools

Trusted Advisor & Health Dashboard

AWS Trusted Advisor

Automated inspection tool that analyzes your AWS environment and recommends improvements across five categories:

  • 💰 Cost Optimization — idle resources, unused RIs
  • ⚡ Performance — high utilization, content delivery
  • 🔒 Security — open ports, MFA on root, public S3 buckets
  • 🛡️ Fault Tolerance — multi-AZ, backups, Route 53 health
  • 📊 Service Limits — approaching account quotas

Basic/Developer: 7 core security checks. Business/Enterprise: all ~500+ checks.

AWS Personal Health Dashboard

Personalized view of AWS service health events that may affect YOUR resources. Alerts you to planned maintenance, outages, and performance degradation in services you use.

Different from AWS Service Health Dashboard (which shows global service status for all customers).

Other Support Resources
  • AWS IQ — connects customers with AWS-certified independent experts for project work
  • AWS Managed Services (AMS) — AWS operates your infrastructure for you
  • AWS Activate — credits and support resources for startups
  • AWS re:Post — community Q&A platform for technical questions
  • AWS Knowledge Center — curated FAQs and how-to articles
