If the AWS account has a limit on the maximum number of VPCs, delete some unused VPCs before creating the RDS instances. The default VPC Security group may be used. Before creating the RDS instances, create a new VPC (Virtual Private Cloud), create a new DB Subnet Group, and optionally create a new security group. Step 1: Creating Oracle and MySQL DB Instances on RDSĪs we shall be using Oracle and MySQL RDS DB instances as the source and target respectively for the DMS migration, create two RDS instances, one for Oracle Database and the other for MySQL. The only prerequisite is an AWS account, which may be created here. Microsoft Azure supports your workload with abundant choices, whether you're working on a Java app, app server, or framework. MySQL and Oracle databases are completely different and you may want to migrate to MySQL for one or more of several reasons such as data types support, operating system support, and scale of deployment. The migration could be necessary if you prefer the open-source MySQL database to the commercial Oracle Database. In this article, we will migrate Oracle Database to MySQL database. The benefits of a cloud-based Database-as-a-Service (DBaaS) include a fully managed service not requiring a DBA, high availability with failover, scalability, and integration with other cloud services for automated monitoring and automated logging. Platform migration-Data on a local machine may be migrated to a cloud database service.Database Consolidation-Multiple source databases may be migrated to a single database for consolidation.
Data replication-Continuous data replication to different target databases for the purpose of testing and development, and regional distribution of databases.A relational database could benefit by migrating to a NoSQL database. A commercial database could be migrated to an open source database and vice versa. Heterogeneous migration could be required to avail of features from another database such as a database data type not supported on the source database. Heterogeneous migration-Migration to a different database engine, for example, Oracle Database to MySQL database.Homogeneous migration could be used to make a backup of a database. Homogeneous migration-Migration to the same database engine type but on a different platform.You may need to migrate a database for one or more of several reasons such as the following: The source database incurs zero downtime during the migration process. The source database could be a database on AWS, a local database, or a database on some other cloud platform such as Oracle Database Cloud service. The target database has to be one of the supported databases on AWS such as one of the AWS Relational Database Service (RDS) hosted databases, Amazon DynamoDB, or Amazon Redshift. AWS Database Migration Service (DMS) is a service to migrate databases on AWS.
