Make Amazon Redshift as AWS DMS Target Database

 

Amazon Redshift database is a data warehouse solution based in the cloud. With Amazon Database Migration Service, you can migrate data from supported databases keeping Redshift as the target. However, it is essential to ensure that the AWS account and the AWS region form a part of the same Redshift cluster.

The first step in DMS REDSHIFT database migration is to move data to an Amazon S3 bucket with AWS DMS. Once the files are located in the S3 bucket, the Amazon S3 automatically transfers the intended tables to the Amazon Redshift data warehouse. The S3 bucket, as pointed out previously has to be in the same AWS Region as the Amazon Redshift database. However, when AWS CLI or DMS API is used for DMS Redshift migration, an AWS Identity and Access Management (IAM) path have to be set up to get access to S3.



Amazon Redshift provides automated processes in the following cases.

·        Modifications made at source tables by incremental data

·        Data type mapping and generation of schema

·        The total load on database tables at the source

·        Synchronization of Change Data Capture (CDC) and full load processes

·        Changes to application of schema in data definition language (DDL) made in the tables at source.

A few basics have to be followed in the DMS Redshift migration process while using an Amazon Redshift database as a target AWS DMS.

The AWS Management Console has to be used for an Amazon Redshift cluster launch and the password, user name, and database name in Redshift and the AWS account have to be noted. Further, the AWS DMS replication instance should be connected through a network to the Amazon Redshift endpoint.

AWS Support to Migration of Databases to S3

Image
  In July 2019, Amazon Web Service Data Migration Service (AWS DMS) announced the launch of a service that would support the migration of data from any source in AWS Apache Parquet data format to S3. The data migrating feature AWS DMS CDC S3   is available in the 3.1.3 version of DMS. S3 is generally used to support DMS while creating data lakes. This data can be used with a wide range of AWS such as Amazon Redshift Spectrum, Amazon EMR, and Amazon Athena. It has been a long-standing demand by users which has now been accepted by AWS with the launch of AWS DMS CDC to S3 . Why do businesses migrate data from AWS DMS CDC to S3? There are several benefits to it. It provides cutting-edge data security, data availability, performance, and scalability which means that organizations can use the S3 for storing and protecting unlimited volumes of data in the cloud. This includes databases with mobile applications, enterprise applications, websites, protection to unlimited volumes...

Features and Functions of Software for Data Replication

Image
  Data replication is the activity where several copies of the same data sets are made and stored in different locations, thereby allowing easy data accessibility across the network. The replicated data can be stored on-site or off-site, in the same system or cloud-based locations. Data replication is so critical that major database technologies such as Microsoft SQL or Oracle database have in-built systems for this activity. Data replication takes place in two ways. One is asynchronous that carries out replication when the Commit statement is issued to the database. The other is synchronous replication where any change that is made to the data at source will be automatically replicated to the data at target. One of the most optimized methods to carry through this process is to use a very effective data replication software . The advantage of the software is that it helps to quickly create a replica of the database at source to a location that is completely independent of the s...
