Features and Functions of Software for Data Replication

 

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 source. This increases data security, ensures data resilience and backup, and supports business continuity.It also offers centralized management of replication policy as the data replication software continuously updates data in real-time over extended periods.

A huge benefit of data replicationis that it allows end-users to access several data sources. In the case of an outage at any location, the replicated database at a secondary location is automatically triggered and users can carry on the work without any break or downtime. When the outage resolves, the primary database is updated and is activated. The more advanced cutting-edge data replication software can capably provide real-time transactional data delivery and integration into data lakes to prop up big data initiatives.

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...

Make Amazon Redshift as AWS DMS Target Database

Image
  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. ยท         Modifications made at source tables by incremental dat...
