Why teams connect Amazon Aurora and Azure SQL Database

Keep Amazon Aurora and Azure SQL Database synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between Amazon Aurora and Azure SQL Database continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • Write enriched or scored records from analytics pipelines back into the Aurora tables that power an application.
  • Offload sync reads to Aurora reader endpoints to avoid load on the writer instance.
  • Expose SaaS data (billing, support tickets) as tables in Azure SQL for reporting teams already on Microsoft tooling.
  • Replicate Azure SQL tables to a warehouse without building custom CDC pipelines.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

Cross-engine sync

Keep the same dataset live in both Amazon Aurora and Azure SQL Database, so each workload runs on the engine that suits it.

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

What you can sync between Amazon Aurora and Azure SQL Database

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Amazon Aurora objects Azure SQL Database objects
Columns and Data Types Standard MySQL or PostgreSQL types mapped during field mapping. Tables The primary sync target; rows map one-to-one to records in the paired system.
Primary and Foreign Keys Constraints used to identify records and preserve relational integrity in syncs. Views Read-only projections used when the sync should expose a curated shape rather than raw tables.
Read Replicas Reader endpoints that syncs can target to keep load off the writer. Schemas Namespaces that organize tables and control which objects a sync user can reach.
Databases Logical databases within a cluster that scope a sync connection. Rows and columns Standard relational records with typed columns; primary keys anchor upserts.
Schemas Namespaces (PostgreSQL) or database-level grouping (MySQL) used in table selection. Stored procedures Existing business logic that some teams invoke on write instead of direct table inserts.
Tables Relational tables synced bi-directionally at row level. Change tracking / CDC tables System-maintained change records used to drive incremental sync.

How the Amazon Aurora and Azure SQL Database connectors work

Amazon Aurora

Integration surface
MySQL or PostgreSQL wire protocol (SQL); optional RDS Data API over HTTPS
Authentication
Database credentials or IAM database authentication
Change detection
Log-based CDC: binlog on MySQL-compatible clusters, logical replication/decoding on PostgreSQL-compatible clusters; polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits for wire-protocol access; throughput is bounded by instance class and connection limits

Azure SQL Database

Integration surface
SQL wire protocol (TDS), the same protocol as SQL Server; T-SQL over standard drivers
Authentication
SQL authentication (database credentials) or Microsoft Entra ID authentication
Change detection
Change data capture or change tracking, both supported on Azure SQL Database; polling as a fallback
Capabilities
read · write · CDC
How it works

How to connect Amazon Aurora to Azure SQL Database — three steps, no code
