Using the ETL Tool for AWS Database Migration

AWS or Amazon Web Service is a high-performing platform that is based in the cloud. There are several cutting-edge services provided by AWS including infrastructure as a service, platform as a service, and packaged software as a service. Also included among the services is facilitating database migration between data warehouses, and relational and NoSQL databases. The only pre-condition for using AWS for database migration is that any one or both of the source and the target databases should be operating in the cloud. 

Among the most optimized methods for database, migration is using the ETL tool for AWS. ETL is short for Extract, Transform, and Load, and the migration takes place over three stages. With the ETL tool for AWS, data is first extracted from the source database, it is then transformed and processed to ensure that it matches the structure of the target database, and finally, this processed data is loaded into the intended database.

Why should you use the ETL tool for AWS for database migration?

There are several reasons for doing so.

• The ETL tool for AWS is fully automated and hence, database migration can be done without any data loss or human errors. This is not so in traditional methods of database migration done manually as human errors are hard to avoid.

• This tool loads data within minutes in real time. In manual movement of databases, especially when petabytes of data have to be moved, the whole activity can take up a lot of time and be inconvenient if the real-time analysis is required.

• Using the ETL tool for AWS for database migration is cost-effective too. In manual systems, the costs of training IT personnel and hiring them can be quite substantial. However, since the ETL tool is automated, overheads are quite low.

• The ETL tool for AWS being automated, there is no question of data inconsistencies during database migration, and the migrated data can be relied upon.

These are some of the reasons why most organizations choose this tool for all activities related to database migration.

What is the most optimized ETL tool for AWS?

There are several tools for AWS that facilitate database migration but the one that is a perfect fit is AWS Glue. With this tool, which is a fully-managed ETL platform, it is very easy to process data for real-time analysis. AWS Glue is very user-friendly and can be set up and running with just a few clicks on the AWS Management Console. Once AWS Glue is configured, all that is required to be done to start database migration is to point the tool where the data is stored for migration.

AWS Glue is ideal in situations where the use case is primarily an ETL process and the data has to be run on a serverless Apache Spark-based platform.
