Migrating Databases with the Amazon Database Migration Service

Why should you migrate databases with Amazon DMS (Database Migration Service)? It is because it enables both Homogenous Migrations like Oracle to Oracle or Heterogeneous Migration like Microsoft SQL Server or Oracle to Amazon Aurora. Further, it also replicates data continually to consolidate databases into a data warehouse with petabyte-volume data streamed to Amazon S3 and Amazon Redshift.


Benefits of Amazon DMS

·        Users do not have to install additional drivers or applications for migration with Amazon DMS and changes are not required to be made to the source database as the process is started with a few clicks only on the AWS Management Console. Data migration is completed automatically by DMS without human intervention at any stage.

·        It is an affordable service and charges are only for the quantum of computing or storage facilities used.

·        With Amazon DMS, changes made to the data at the source are continually replicated to the target provided both the source and the target databases are kept in sync.

·        Amazon DMS supports almost all the common databases in commercial and open-source applications and hence data can be moved between text-based targets, SQL, and NoSQL.

·        The AWS Management Console of Amazon DMS quickly starts the migration activity once the parameters are defined in AWS DMS. The pre-migration activity includes setting up connections to both the source and the target databases and choosing the replication instance as well as conducting test runs before the actual migration process begins.

·        During migration, Amazon DMS closely monitors the source and target databases, the replication instance, and the network connectivity.         

AWS Database Migration Service is also used to consolidate various source databases into a single database.

Amazon Web Service Database Migration Service – AWS DMS – is a cloud-based platform. It is optimized for migrating databases from on-premises databases to the cloud, between cloud providers, as well as relational databases, data warehouses, and NoSQL databases. By using AWS DMS, all the benefits of the cloud such as increased speed and database performance are available to users. Why Should you Migrate Databases with AWS DMS S3 (Simple Storage Service)? The benefit of database migrating with AWS DMS to S3 is unlimited data storage facilities. It is possible to scale up storage repository volumes whenever there is a spike in demand without having to add to the existing hardware and software. Payment is as per the pay-as-you-use model and unlike traditional databases, no flat fees are charged, leading to substantial cost savings. Further, S3 offers high data protection, cost affordability, access management, and data replication functionalities with the ability to carry out limitles...

Database Replication and the Features of An Optimized Tool

Image
Database replication is the process of copying data from a central database to one or several other databases. The publisher is the source database while the subscriber is the intended target database with allusers havingaccess to the same data and records.Since this is such a critical process for organizations and to ensure that data movement is optimized, only the best database replication tool should be used. A host of functions are supported by a database replication tool. These include data security, disaster data recovery and resilience, and business continuity. However, the functions of a database replication tool are quite different from data backup even though both are often used interchangeably. In replication, the entire database is replicated and changes made periodically in the source database are continually updated in the target system whereas backup is a one-shot activity. One major advantage of a database replication tool is facilitating business continuity. Data is r...
