Why teams connect Amazon Lightsail and AWS Aurora PostgreSQL

Keep Amazon Lightsail and AWS Aurora PostgreSQL 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 AWS Aurora PostgreSQL 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

  • 01 Push cleaned or enriched records from central systems back into the Lightsail database behind a small web app.
  • 02 Migrate data continuously from a Lightsail database to a larger managed database as an application outgrows the VPS tier.
  • 03 Sync JSONB-heavy application data into structured objects in downstream business systems.
  • 04 Keep a customer-facing Aurora database aligned with an internal admin tool, with writes accepted on both sides.

Common sync patterns

Cross-engine sync

Keep the same dataset live in both Amazon Lightsail and AWS Aurora PostgreSQL, 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 AWS Aurora PostgreSQL

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 AWS Aurora PostgreSQL objects How this pairing syncs
Tables Relational tables read from and written to at row level. Tables The core sync unit; rows are matched across systems by primary key. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Managed Databases Lightsail-hosted MySQL or PostgreSQL instances that a sync connects to as standard databases. Foreign keys Relationship metadata that syncs can translate into object references elsewhere. Managed Databases is specific to Amazon Lightsail and Foreign keys to AWS Aurora PostgreSQL — each maps to any object or custom field on the other side.
Databases Logical databases on the instance that scope a connection. Replication slots and publications The logical replication objects that power log-based CDC. Databases is specific to Amazon Lightsail and Replication slots and publications to AWS Aurora PostgreSQL — each maps to any object or custom field on the other side.
Schemas Namespaces used when selecting tables to sync. Databases and schemas PostgreSQL's two-level namespace scopes which tables a sync connection targets. Schemas is specific to Amazon Lightsail and Databases and schemas to AWS Aurora PostgreSQL — each maps to any object or custom field on the other side.
Views Query-backed read-only sources. Rows Inserted, updated, and deleted in both directions during bi-directional syncs. Views is specific to Amazon Lightsail and Rows to AWS Aurora PostgreSQL — each maps to any object or custom field on the other side.
Users and Grants Database accounts used to give the sync connection scoped access. Columns Rich Postgres types including JSONB and arrays are mapped to the paired system's fields. Users and Grants is specific to Amazon Lightsail and Columns to AWS Aurora PostgreSQL — each maps to any object or custom field on the other side.

How changes propagate between Amazon Lightsail and AWS Aurora PostgreSQL

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Amazon Lightsail AWS Aurora PostgreSQL Interval-based propagation

DetectionStacksync polls Amazon Lightsail for changes on an incremental schedule, reading only records changed since the previous pass. Polling on timestamp or key columns.

DeliveryEach detected change is applied to AWS Aurora PostgreSQL as a row-level write, with types converted between the two schemas.

AWS Aurora PostgreSQL Amazon Lightsail Sub-second propagation

DetectionChanges in AWS Aurora PostgreSQL are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication (WAL decoding through replication slots), with timestamp polling as a fallback.

DeliveryEach detected change is applied to Amazon Lightsail as a row-level write, with types converted between the two schemas.

How the Amazon Lightsail and AWS Aurora PostgreSQL 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

AWS Aurora PostgreSQL

Integration surface
SQL wire protocol (PostgreSQL-compatible), standard Postgres drivers and JDBC
Authentication
Database credentials, optionally AWS IAM database authentication, over TLS
