Why Should You Migrate Databases with Amazon DMS

 With Amazon DMS (Amazon Database Migration Service), you can optimize the migration of databases from on-premises databases to the cloud or from one cloud provider to another. The migration activity may be a one-time process from the source to the target database or continuous replication of data between the two provided they are always kept in sync. Amazon DMS also facilitates database migration between NoSQL databases, relational databases, and data warehouses.


Migration with Amazon DMSis fast and seamless as managing, tracking, and deploying the infrastructure for migration is auto-managed by the software once it is configured. DMS supports the complete infrastructure for database migration including software patching, error reporting, and tracking of hardware and software. This is against previous methods where additional hardware and software had to be installed for database migration.

Database migration with Amazon DMS provides great flexibility and unlimited data storage options. Users have to pay only for the quantum of resources used and download additional storage capacity in minutes whenever there is a sudden spike in demand. In older databases, flat fees were charged regardless of what is used. Hence Amazon DMSmigration is a very cost-effective proposition too.

A very important feature of Amazon DMS is the failover mode. In the case of an outage of the primary server, the secondary servers are automatically triggered and the work goes on without interruptions. After the outage is resolved, the primary server is automatically updated with all the changes that took place in the break period. 

Finally, Amazon DMSensures complete data security, encrypting data at source with the AWS Key Management Service and data on the move with Secure Socket Layer (SSL).

Why Should You Decide for Database Oracle Replication

Image
Oracle has been at the forefront of database management systems for decades and organizations have built up an environment from their Oracle database that increases operational efficiencies. The most optimized way for this which is typically preferred is O racle replication of databases, a technique where data access is ensured from a wide range of sources like servers and sites. O racle replication allows real-time data access and therefore has high data availability. In the oracle  replication process , data is shared, distributed, and consolidated so that organizations can keep it in sync across various locations and share it with partners. This data is present in different branches and wherever there is a need to create multiple copies of the database. These copies are all synchronized and allow backups in case of disaster recovery, testing, distributed data processing, and business reporting.  The Benefits of O racle Replication There are several benefits of O racle repl...

Using the ETL Tool for Amazon Web Service Database Migration

Image
One of the most optimized cloud-based platforms in use today is the Amazon Web Service (AWS). It offers a wide range of services including unlimited storage capacities and high computing powers, both very critical in the modern data-driven business environment. The advantage of AWS is that storage and computing are in separate silos, helping businesses to accurately calculate the costs of running them. However, it is the DMS (Database Migration Service) of AWS that is crucial for organizations to carry out database migration for which the  AWS DMS ETL  tool is most used because of its cutting-edge features. ETL is short for Extract, Transform, and Load and is used for combining several databases into a centralized storage repository or a data warehouse. The AWS DMS ETL tool has three functions for migrating databases from on-premises systems to the cloud or from one cloud provider to another. The first function is to extract data from the source, followed by transforming the d...
