Using Amazon DMS to Migrate Databases

-

Amazon DMS is the data migration service of Amazon Web Service and is optimized to migrate databases from on-premises systems to the cloud or between two cloud providers. It is possible to choose between carrying out one-time migration or continuous data replication between the source and the target databases, provided both are kept always in sync. Databases can be migrated with Amazon DMS from relational databases, data warehouses, and NoSQL databases. 

There are several reasons why organizations use Amazon DMS for database migration. Here are a few of them.

·        Migration with Amazon DMS is a quick and seamless process as the software, once configured, handles the complete process of managing, deploying, and configuring all the required infrastructure for migration. 

·        The software is flexible and users can scale as needed in data storage, paying only for the quantum of resources used. Additional storage required can be downloaded in minutes.

·        An important feature of Amazon DMS is the failover feature. In the event of an outage or crash of the primary server, the secondary servers onsite or in remote locations are automatically triggered and there is no downtime or stoppage of work. After the issue is resolved, the primary server is updated with the data changes during the break period. There is thus no loss of data.

·        Migration with Amazon DMS entails moving databases to more cost-effective and advanced platforms. Users can avail managed database services like Amazon Relational Database Service or Amazon Aurora and low-cost storage repositories such as Amazon S3 or fully-managed data warehouses of Amazon Redshift.

These are some of the advanced features that make Amazon DMS the preferred option for data migration by modern enterprises.

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...

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 databas...
