{"slug":"mysql-vs-amazon-aurora)","title":"MySQL vs Amazon Aurora","url":"https://www.aversusb.net/compare/mysql-vs-amazon-aurora)","faqCount":5,"faqs":[{"question":"Is Amazon Aurora truly MySQL-compatible or will I need to rewrite my application?","answer":"Aurora maintains MySQL 5.7 and 8.0 wire protocol compatibility, meaning most applications run without code changes. However, some edge cases exist: Aurora doesn't support certain storage engines (InnoDB is standard), uses different system variables, and handles certain edge-case SQL differently. Plan for 1-2 weeks of compatibility testing for production workloads."},{"question":"When does Amazon Aurora become cheaper than self-managed MySQL?","answer":"Aurora typically becomes cost-effective when self-managed costs exceed $100-150/month. This occurs when: (1) you need 99.99% uptime requiring multi-server redundancy, (2) you employ a full-time DBA ($80k+ annually), or (3) infrastructure downtime costs exceed $5,000/hour. For hobby projects or low-traffic sites, MySQL self-hosted remains cheaper."},{"question":"Can I migrate from MySQL to Aurora without downtime?","answer":"AWS Database Migration Service (DMS) enables near-zero downtime migration using binary log replication. Typical migration: (1) full initial data copy (hours-days depending on size), (2) continuous replication of changes, (3) final cutover during a planned maintenance window (minutes). For databases under 500GB, migration usually completes in under 6 hours."},{"question":"What are the hidden costs of running Aurora that I should budget for?","answer":"Beyond instance pricing: backup storage costs (~$0.023/GB/month for data beyond 100% of database size), data transfer egress ($0.02/GB out of region), enhanced monitoring ($12/month), and AWS support plans ($29-15,000+/month). A typical 500GB database with backups might add $50-100/month to base instance costs."},{"question":"If my application outgrows MySQL performance, do I have to switch to Aurora or are there alternatives?","answer":"Before switching: optimize MySQL with proper indexing, connection pooling (ProxySQL), read replicas, or sharding. Open-source alternatives include PostgreSQL (similar capabilities, better JSON support) or MariaDB (MySQL fork with built-in clustering). If you need distributed performance, consider Redis for caching. Aurora is optimal if you want AWS-managed automation without architectural changes."}],"faqPageSchema":{"@context":"https://schema.org","@type":"FAQPage","@id":"https://www.aversusb.net/compare/mysql-vs-amazon-aurora)#faq","url":"https://www.aversusb.net/compare/mysql-vs-amazon-aurora)","inLanguage":"en-US","name":"MySQL vs Amazon Aurora — FAQ","description":"Frequently asked questions about MySQL vs Amazon Aurora","dateModified":"2026-07-09T06:50:20.759Z","author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"publisher":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"isPartOf":{"@type":"Article","@id":"https://www.aversusb.net/compare/mysql-vs-amazon-aurora)#article"},"license":"https://creativecommons.org/licenses/by/4.0/","speakable":{"@type":"SpeakableSpecification","cssSelector":["#faq",".faq-item"]},"mainEntity":[{"@type":"Question","name":"Is Amazon Aurora truly MySQL-compatible or will I need to rewrite my application?","acceptedAnswer":{"@type":"Answer","text":"Aurora maintains MySQL 5.7 and 8.0 wire protocol compatibility, meaning most applications run without code changes.
