Question 1

What does Aurora MySQL consulting include?

Accepted Answer

Aurora-specific architecture decisions: cluster topology (writer + readers, Multi-AZ vs Multi-Region), Aurora Serverless v2 vs provisioned sizing, Backtrack configuration for point-in-time rewind, Global Database for cross-region disaster recovery, parameter group tuning (Aurora exposes a different surface than RDS MySQL), and the Aurora-MySQL-vs-RDS-MySQL-vs-self-managed economics. Deliverables are written recommendations, not deployment work.

Question 2

Aurora MySQL vs RDS MySQL — which fits?

Accepted Answer

Aurora MySQL wins for: read-heavy workloads (up to 15 read replicas sharing cluster storage), multi-region active-active via Global Database, fast failover (typically <30 seconds), or workloads that benefit from Aurora's cluster-storage performance characteristics. RDS MySQL wins for: cost-sensitive workloads at smaller scale, exact MySQL community-edition compatibility, or when Aurora's premium pricing isn't justified by the feature delta. See our Aurora vs RDS comparison for the deeper view.

Question 3

What's Aurora's cluster storage architecture?

Accepted Answer

Aurora decouples compute from storage — the database engine runs on EC2-like instances while the storage layer is a purpose-built distributed system across 3 Availability Zones (6 copies of data, 4-of-6 quorum writes, 3-of-6 quorum reads). This gives near-instant read-replica creation, fast failover (no log replay needed), and survivability across AZ failure without explicit configuration. The trade-off: Aurora's storage charges per IO, which can become expensive at high QPS — Aurora I/O-Optimized billing tier addresses this for IO-heavy workloads.

Question 4

What is Backtrack and when do you use it?

Accepted Answer

Backtrack is Aurora MySQL's point-in-time rewind capability — you can roll the cluster back to a specific second in the past (up to 72 hours) without restoring from a snapshot. Use cases: undo accidental DROP TABLE or destructive UPDATE/DELETE, recover from application bugs that corrupted data, or rapid testing rollback. Backtrack is not a replacement for backups (it's in-cluster rewind, not durable point-in-time recovery), but it's significantly faster than snapshot restore for 'oh no' moments.

Question 5

Aurora Global Database — when is multi-region worth it?

Accepted Answer

Global Database replicates Aurora across regions with typical lag <1 second. Use cases: regulatory data-residency requirements with cross-region disaster recovery, low-latency reads for global users (each region has read replicas), or rapid recovery from full-region failure (promote a secondary region). The cost is real — running Aurora in N regions means N× compute + storage + cross-region replication. We model the workload + DR requirements before recommending.

Question 6

Aurora Serverless v2 — when does it fit?

Accepted Answer

Serverless v2 scales compute granularly (0.5 ACU steps) with sub-second response to load changes. Best for: variable workloads (dev/test, spiky traffic patterns, multi-tenant SaaS where tenant load varies), unpredictable scaling needs, or cost-conscious workloads where the steady-state is small but bursts are common. Avoid for: predictable steady-state production where provisioned reserved-instance pricing is meaningfully cheaper, or workloads with strict latency budgets that need pre-warmed compute.

Question 7

RDS MySQL → Aurora MySQL migration — what's the path?

Accepted Answer

Cleanest path: AWS DMS (Database Migration Service) or RDS' built-in 'migrate to Aurora' option for in-cluster snapshot-based migration. The latter is operationally simpler but has more downtime; DMS supports near-zero-downtime with logical replication. Either way, schema-level changes are minimal — Aurora MySQL accepts the same SQL surface as MySQL 8.x. Application-tier changes are usually limited to endpoint updates. We design the cutover sequence with replication-lag gates and rollback path.
