====== Free Tier ======

**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
