AWS DMS stands for AWS Database Migration Service. It is a fully managed service provided by Amazon Web Services (AWS) that enables you to migrate databases to AWS quickly and securely. AWS DMS supports both homogeneous and heterogeneous database migrations, allowing you to migrate data between different database engines and cloud platforms with minimal downtime and data loss.
Here are some key features and capabilities of AWS DMS:
-
Database Migration: AWS DMS facilitates the migration of databases from on-premises data centers, other AWS regions, or other cloud platforms to AWS. It supports migrations between various database engines, including Oracle, SQL Server, MySQL, PostgreSQL, MariaDB, MongoDB, and Amazon Aurora.
-
Continuous Data Replication: AWS DMS enables continuous data replication from source to target databases, ensuring that changes made to the source database are replicated to the target database in near real-time. This minimizes downtime and data loss during the migration process.
-
Schema Conversion: AWS DMS includes schema conversion tools that help you convert database schemas and objects between different database engines. This allows you to migrate databases with different schema structures without manual intervention, reducing complexity and effort during the migration process.
-
Full Load and CDC (Change Data Capture): AWS DMS supports both full load and CDC migration methods. Full load migrates the entire dataset from the source to the target database initially, while CDC captures and replicates incremental changes made to the source database after the initial load.
-
Managed Service: AWS DMS is a fully managed service, meaning AWS handles infrastructure provisioning, replication setup, monitoring, and maintenance tasks. This allows you to focus on migrating your databases without the overhead of managing migration infrastructure.
-
Highly Available and Scalable: AWS DMS is designed for high availability and scalability, with built-in fault tolerance and automatic failover capabilities. You can scale up or down the replication instance size and storage capacity based on your migration requirements.
-
Integration with AWS Services: AWS DMS integrates seamlessly with other AWS services such as AWS Schema Conversion Tool (SCT), AWS Database Schema Discovery, AWS Database Migration Assessment Tool, Amazon CloudWatch, AWS Lambda, and AWS CloudFormation.
Overall, AWS DMS simplifies and accelerates the database migration process to AWS, enabling you to migrate databases with minimal downtime, data loss, and manual effort. It provides a reliable and cost-effective solution for migrating databases to AWS, whether you're migrating from on-premises environments, other AWS regions, or other cloud platforms.
