In their own words
Amazon Database Migration Service
Amazon Database Migration Service (AWS DMS) is a SaaS service for moving relational databases, data warehouses, NoSQL databases and other data stores to AWS or between cloud and on-premises environments. It handles one-time migrations and continuous replication, with support for both like-for-like and cross-engine moves. AWS says more than 20 databases and data warehouses can serve as source or target endpoints. DMS Schema Conversion assesses schemas and converts many code objects, including views, stored procedures and functions, while identifying work that needs manual conversion. DMS Serverless provisions and scales capacity according to transaction volume, billed hourly. Multi-AZ deployment uses redundant replication instances, and interrupted migrations can resume. API and AWS CLI support automation, while CloudTrail and CloudWatch Logs provide integrations. TLS, VPC deployment, PrivateLink and column masking are available. At least one endpoint must be Amazon RDS or EC2; on-premises-to-on-premises replication is unsupported. The AWS Free Tier offers free with credits.
Estuary
Estuary is a managed data integration platform for combining change data capture, batch, streaming, and app synchronization for analytics, operations, and AI. It supports transformations while data is moving, using SQL, Python, or TypeScript, and describes delivery as exactly once with end-to-end latency under 100 milliseconds. More than 200 prebuilt connectors cover databases, warehouses, SaaS apps, and cloud platforms, including Snowflake, BigQuery, Kafka, MySQL, and PostgreSQL. Customers can store data in their own cloud bucket for a duration they choose, and select public, private, or Bring Your Own Cloud deployment. Estuary lists SOC 2 Type II, HIPAA, HITECH, CCPA, and GDPR among its compliance standards, and says data is encrypted in transit and at rest. It is available through API, self-hosted, and web options. The indefinite free tier is limited to 10 GB per month and two concurrent connector instances; paid plans start at $100 a month.
