Optimizing Migration of Databases with Amazon DMS

Regardless of whether it is from on-premises to the cloud or from one cloud provider to another, migration of databases is greatly optimized with Amazon DMS, the Data Migration Service of Amazon Web Service. You have the option to either choose one-time migration from the source to the target database or continually replicate data between the two. But for this to take place both the source and the target have to be kept in sync. Amazon DMS enables migration between on-premises databases to the cloud, from one cloud provider to another, NoSQL databases, relational databases, and data warehouses.

There are several benefits of migrating databases using Amazon DMS when compared to traditional databases.

First, and most importantly, migration with Amazon DMS is quick and seamless as the software manages, tracks, and deploys, all the necessary infrastructure for migration once it is configured. In the methods of the past, additional applications and hardware had to be installed before the migration could be initiated.

Next, in traditional systems, one-time flat fees were charged regardless of the volume of data storage capabilities used for migration. However, Amazon DMS offers unlimited flexibility and users can scale up or down in data storage as per requirement by paying only for the quantum of resources used. This leads to substantial savings in the cost of migration.

Finally, the failover feature is a very critical benefit of database migration with Amazon DMS. In the case of a crash of the primary server during migration, the feature triggers the secondary servers whether onsite or in remote locations, and the migration process is not interrupted.

These benefits make Amazon DMS the ideal tool for database migration.

The Optimized Uses of a Database Replication Tool

Image
Database replication is the process of copying data from a central database to one or several other databases. After replicating data from a source to a target, all users have access to the same data and records. However, to ensure that the data is replicated without any loss or errors the best database replication tool must be used. A wide range of functions that include data security, disaster data recovery and resilience, and business continuity are supported by the database replication tool. The replication process is auto-managed by the software across diverse sources and targets. A database replication tool ensures data consistency for end-users through multiple data stores. The primary benefit of replication is that the source database remains fully functional during database migration without the need for downtime or shutting down systems. This is a big help for large enterprises for whom downtime even for a brief period can badly affect their daily operations. Further, a data...

Understanding Real-Time Data Replication and Its Need

Image
As the need to access data frequently grows exponentially, one of the biggest challenges faced by organizations is high data availability. There is an urgent need to scale up systems to get robust and speedier access to data. Even though highly optimized data transfer and storage technologies have helped this cause, it is real-time data replication   that has triggered an organized mechanism to maxixe data availability. Defining Real-Time Data Replication Real-time data replication is the process that synchronizes data across a source and a destination database as and when a change occurs in the data source. Most popular databases offer in-depth and robust support for replicating data in real-time. This allows users to generate numerous copies of complex datasets and store them in various locations thereby ensuring seamless access and high availability of data for individual systems and numerous servers. The Need for Real-Time Data Replication Given here are two instances that call...

Why Should You Use Amazon ETL for Database Migration

Image
Amazon Web Service is a cloud-based service that optimizes data migration from on-premises databases to the cloud or from one cloud provider to another. All these processes are best carried out with the Amazon ETL tool. Amazon ETL ( Extract, Transform, and Load) can combine various data warehouses or databases into a centralized storage repository. The workflow is as follows - data is extracted from the database from which it has to be migrated, transformed, and formatted to match the data structure of the target database, and finally loaded into the target database, completing the migration process.  The Amazon ETL process is automated leading to high data accuracy and performance, and low migration costs.  Benefits of Amazon ETL for database migration . Here are a few of them. ·         Amazon ETL seamlessly migrates on-premises databases to Amazon RDS or Amazon EC2, and Aurora, as well as databases running on EC2 to RDS or vice versa. I...
