====== Aurora Cluster ======

**What it is:** The Aurora database setup containing a writer instance and reader instances.

**What it’s for:**
  * Separate read and write traffic.
  * Failover within the cluster.

**Key ideas:**
  * Clients can use a writer endpoint and a reader endpoint.
  * Failover can promote a reader to writer.

**Exam cues:**
  * “separate endpoints for reads/writes” → Aurora cluster endpoints.

**Hard words:**
  * *promote* /prəˈmoʊt/: nâng lên
  * *writer* /ˈraɪtər/: máy ghi
  * *reader* /ˈriːdər/: máy đọc
