Amazon Web Service Database Migration Service (AWS DMS) is a service based in the cloud, ensuring smooth and seamless migration between relational databases, data warehouses, NoSQL databases, and other databases in any form. AWS DMS migrates databases from on-premises servers to the cloud and from one cloud provider to another.

A very popular and commonly-used resource used in this type of migration is the AWS DMS ETL tool.

Extract, Transform, Load (ETL) is a tool by which multiple databases can be combined for storing in a data warehouse or a centralized database. It involves three processes – extracting data from a source, transforming that data into a format that best suits specific needs, and finally, loading the data into a target repository or any other database. The optimized features of ETL include quick data monitoring and management, easy data installation and integration, real-time streaming, and high data security policies.

There are other advantages of AWS DMS ETL. One is that the migration process can be done without any data loss at very affordable charges. Next, since the complete AWS DMS ETL migration is automated, trained professionals and database administrators do not have to constantly track the process. This in itself is a cost-saving factor. The best tools for AWS are AWS Glue and AWS Data Pipeline.

Benefits of AWS DMS with ETL

AWS DMS ETL offers several benefits that make it the preferred mode of organizations needing to migrate databases.

•Easily manageable: With AWS DMS ETL, businesses do not have to make any changes to the source database or install additional drivers and applications for database migration. A few clicks on the AWS Management Console are enough to begin the process. Migration is fully automated through AWS DMS ETL and any changes at the source are replicated smoothly through Change Data Capture to the target database.

•Negligible downtime: The source database remains fully functional during migration as AWS DMS ETL continually updates changes made at the source database to the target database at pre-set intervals. But for this to happen, the source and the target databases have to be in sync for as long as necessary. This benefit is very important for large enterprises that are data-driven as they cannot afford to shut down their systems even for short periods.

•Supports all common databases: The popular databases generally used by modern-day businesses are supported by AWS DMS. Both homogeneous migrations carried out when the database engines of the source and target databases are similar and heterogeneous migration when they are different is supported by the AWS DMS ETL. Migration is possible between on-premises databases to Amazon RDS or Amazon EC2, Aurora, and databases running on EC2 to RDS or vice versa. Data can also be migrated between SQL, text-based data, and NoSQL with DMS AWS.

Summing up, AWS DMS ETL provides all the advanced and cutting-edge features inherent in the cloud environment.
