Why teams connect Amazon Lightsail and Azure Cosmos DB

Keep Amazon Lightsail and Azure Cosmos DB 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 Lightsail and Azure Cosmos DB 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

  • Sync a Lightsail-hosted application database with a CRM so customer records match what the app stores.
  • Push cleaned or enriched records from central systems back into the Lightsail database behind a small web app.
  • Mirror Cosmos DB items into Postgres so teams can query operational data with standard SQL.
  • Two-way sync between a Cosmos DB-backed product catalog and a PIM or commerce platform.

Cross-engine sync

Keep the same dataset live in both Amazon Lightsail and Azure Cosmos DB, 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.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

What you can sync between Amazon Lightsail and Azure Cosmos DB

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 Lightsail objects Azure Cosmos DB objects
Managed Databases Lightsail-hosted MySQL or PostgreSQL instances that a sync connects to as standard databases. Partition keys Determine data distribution and must be included on writes for the sync to route items correctly.
Databases Logical databases on the instance that scope a connection. Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync.
Schemas Namespaces used when selecting tables to sync. Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation.
Tables Relational tables read from and written to at row level. Databases Top-level namespaces that scope containers and throughput provisioning.
Views Query-backed read-only sources. Containers The unit of partitioning and throughput; each container maps to a synced collection.
Users and Grants Database accounts used to give the sync connection scoped access. Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed.

How the Amazon Lightsail and Azure Cosmos DB connectors work

Amazon Lightsail

Integration surface
MySQL or PostgreSQL wire protocol (SQL) to the managed database endpoint
Authentication
Database credentials; public endpoint access must be enabled or a tunnel used
Change detection
Polling on timestamp or key columns; log-based CDC depends on engine parameter access, which is more limited than on full RDS
Capabilities
read · write
Rate limits
No API-style rate limits; capacity is fixed by the chosen Lightsail bundle

Azure Cosmos DB

Integration surface
REST API and SDKs over HTTPS (API for NoSQL, formerly the SQL API); also MongoDB, Cassandra, Gremlin, and Table API surfaces
Authentication
Account keys, resource tokens, or Microsoft Entra ID role-based access
Change detection
Built-in change feed exposing inserts and updates in order within each partition key range
Capabilities
read · write · CDC
