What it is: A set of AWS usage limits that are free for new accounts or always-free services (varies by service).

What it’s for:

• Learn and try AWS with minimal cost.
• Build small demos and test environments.

Key ideas:

• Limits differ by service and may be time-limited or always-free.
• Still requires monitoring to avoid accidental charges.

Exam cues:

• “new to AWS, want to practice” → Free Tier (but watch limits).

Hard words:

• *limit* /ˈlɪmɪt/: giới hạn
• *accidental* /ˌæksɪˈdentl/: vô tình
