The Functioning of Data Migration Service of AWS

-

The Database Migration Service of Amazon Web Service (DMS AWS) is a cloud-based platform that ensures seamless migration of databases from on-premises systems to the cloud or between different cloud providers. Users can choose between one-time data migration or continual replication between the source and the target but for that, the two have to always be in sync. DMS AWS is ideal for migrating data from relational databases, NoSQL databases, or data warehouses.

Since DMS AWS is a cloud-based replication software, the first criteria for it to function is to establish a link between the source and the target database. This informs the system about where the data is sourced and where it has to be moved. Next, the activity that will load the data from the source to the target has to be defined.

Once these steps are completed, DMS AWS handles the migration process automatically even if the keys and the tables required for migration are not present in the target database. In such instances, the AWS SCT (AWS Schema Conversion Tool) has to be used for creating indexes, tables, views, and triggers in the target database.All the benefits inherent in a cloud-based environment like data security and usage flexibility, cost efficiency, and enhanced performance are available when databases are migrated with DMS AWS.

Users get unmatched scalability with DMS AWS. Users can scale up and down in data usage by paying only for the quantum of resources used, unlike traditional databases where high one-time fees are charged. Further, whenever additional data storage capacity is required, the same can be downloaded immediately.

These are some of the areas of optimized functioning of DMS AWS.

Why Should You ETL from Oracle to SQL Server

Why do businesses want to ETL from Oracle to SQL Server   when it comes to database migration? Though the Oracle database system has been the foundation of data-driven businesses for decades, the high licensing costs make maintaining the database prohibitively expensive, particularly when system upgrading is required. Additionally, the ETL (Extract, Transform, Load) tool is perfect for this type of data migration leading to organizations preferring this method over any other. One of the main reasons for ETL from Oracle to SQL Server is that the data replication process is fully automated. The tool can be easily configured and set up in a day and data replication from Oracle to Microsoft SQL Server is carried out in real-time. Additionally, data ingestion speeds are lightning-fast and the process is not only very cost-effective but user-friendly too. Moreover, for ETL from Oracle to SQL Server,   there is no need for additional and complex coding as Oracle replication is deliv...
