Two-way sync
Changes in Amazon Lightsail or Azure Cosmos DB instantly reflect in both systems. No stale data, no manual imports.
Keep Amazon Lightsail and Azure Cosmos DB in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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.
Keep the same dataset live in both Amazon Lightsail and Azure Cosmos DB, so each workload runs on the engine that suits it.
When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.
Services that own separate databases stay consistent on the records they share, without a custom replication layer.
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 | How this pairing syncs | |
|---|---|---|---|
| Databases Logical databases on the instance that scope a connection. | Databases Top-level namespaces that scope containers and throughput provisioning. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Users and Grants Database accounts used to give the sync connection scoped access. | Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. | Users and Grants is specific to Amazon Lightsail and Partition keys to Azure Cosmos DB — each maps to any object or custom field on the other side. | |
| Managed Databases Lightsail-hosted MySQL or PostgreSQL instances that a sync connects to as standard databases. | Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. | Managed Databases is specific to Amazon Lightsail and Change feed entries to Azure Cosmos DB — each maps to any object or custom field on the other side. | |
| 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. | Schemas is specific to Amazon Lightsail and Stored procedures and triggers to Azure Cosmos DB — each maps to any object or custom field on the other side. | |
| Tables Relational tables read from and written to at row level. | Containers The unit of partitioning and throughput; each container maps to a synced collection. | Tables is specific to Amazon Lightsail and Containers to Azure Cosmos DB — each maps to any object or custom field on the other side. | |
| Views Query-backed read-only sources. | Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. | Views is specific to Amazon Lightsail and Items (JSON documents) to Azure Cosmos DB — each maps to any object or custom field on the other side. |
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.
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 Azure Cosmos DB as a row-level write, with types converted between the two schemas.
DetectionChanges in Azure Cosmos DB are captured at the source via change data capture — no polling loop against its API. Built-in change feed exposing inserts and updates in order within each partition key range.
DeliveryEach detected change is applied to Amazon Lightsail as a row-level write, with types converted between the two schemas.
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Amazon Lightsail–Azure Cosmos DB connection.
Changes in Amazon Lightsail or Azure Cosmos DB instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Amazon Lightsail or Azure Cosmos DB data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Amazon Lightsail or Azure Cosmos DB record.
Track your Amazon Lightsail ⇄ Azure Cosmos DB sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Amazon Lightsail and Azure Cosmos DB.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Amazon Lightsail and Azure Cosmos DB with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Amazon Lightsail and Azure Cosmos DB objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Amazon Lightsail and Azure Cosmos DB: authenticate both systems, choose the objects to sync (such as Amazon Lightsail's Databases and Users and Grants), map fields visually, and changes propagate both ways in milliseconds — no code required.
Common patterns for Amazon Lightsail and Azure Cosmos DB: Cross-engine sync; Migration with zero-downtime cutover; Shared reference data between services. Keep the same dataset live in both Amazon Lightsail and Azure Cosmos DB, so each workload runs on the engine that suits it.
Amazon Lightsail: MySQL or PostgreSQL wire protocol (SQL) to the managed database endpoint. Authentication: Database credentials; public endpoint access must be enabled or a tunnel used. Azure Cosmos DB: 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. Stacksync manages authentication, retries, and rate limits on both sides.
Amazon Lightsail: Lightsail targets simplified, fixed-price bundles; database configuration options are narrower than full Amazon RDS, which affects how much replication tuning is available. Azure Cosmos DB: The same account can be exposed through multiple wire-compatible APIs (NoSQL, MongoDB, Cassandra, Gremlin, Table), and the API choice fixes how a connector must speak to it. Stacksync's field mapping accounts for these differences between Amazon Lightsail and Azure Cosmos DB without custom code.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Amazon Lightsail and Azure Cosmos DB records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Amazon Lightsail and Azure Cosmos DB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Amazon Lightsail–Azure Cosmos DB integration in-house.
As a data company, we understand the importance of keeping your data secure. Stacksync is built with security best practices to keep your data safe at every layer, and is DPF-certified for US, EU, UK and CH data transfers.
Let your users access Stacksync from your centralized user management systems. Works with Okta, Azure, Google SSO and more.
Immediately get alerted about record syncing issues over email, Slack, PagerDuty and WhatsApp. Resolve issues from a centralized dashboard with retry and revert options.
