Database Migration with AWS DMS Services

Among the many services provided by AWS (Amazon Web Service) is database migration (DMS or Database Migration Service) from on-premises servers to the cloud, data warehouses, relational databases, NoSQL databases, and between one cloud provider to another. The only condition for availing of AWS DMS services is that one of the sources or the target databases should be operating on the cloud as AWS DMS is a cloud-based platform.

There are three types of database migration offered by AWS DMS services.

·        Full-load database migration: In this instance, both the source and the target databases are shut down and all the data at the source is migrated to the target database in one go.

·        On-going database migration: Here, the source and the target databases are kept in sync and once the full-load data migration is completed, ongoing changes and incremental data are migrated at pre-set intervals.

·        Change Data Capture: In this option, only changes that occur in the source database are moved to the target database.

Organizations can decide to choose from these AWS DMS services as per their needs.

There are several benefits to using AWS DMS services.

·        Once AWS DMS is configured, migration is initiated quickly as the service auto-deploys, manages, and monitors all the necessary infrastructure required for database migration. This includes software patching, error reporting, and tracking the performance of the hardware and software.

·        High flexibility and scalability as users can download only the storage resources required for migration and pay only for the quantum utilized. Any extra storage required can be downloaded in minutes.

These are some reasons why users prefer AWS DMS services for database migration to the cloud.

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...

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...
