Amazon Database Migration Service vs Striim

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.

Striim is a change data capture and streaming platform for integrating data across databases, applications, and clouds in real time. Its distributed streaming SQL supports continuous queries and joins with historical caches, with processing described at a scale of up to billions of events per minute. Striim can capture schema changes and lets users choose how consumers propagate them, or halt and alert for manual resolution. Monitoring covers pipeline health, end-to-end latency, and table-level metrics, and REST APIs support integration. Striim says it connects hundreds of enterprise sources and targets, including Oracle, Kafka, Salesforce, Snowflake, and Google BigQuery. Striim Cloud is managed and available on AWS, Google Cloud, and Microsoft Azure; Striim Platform can run on-premise or in a self-managed cloud. The free Developer plan is capped at 25 million events per month and includes trial access to premium, standard, and more than 200 preview application connectors.
