RDS Oracle is a relational database application that supports Multi-AZ deployment environments. The Multi-AZ platform supports MySQL services and Oracle RDS Instances that run on different Oracle database editions. It is possible to generate replicas of primary database instances and save the results in a remote physical location known as the remote Availability Zone (AZ).
The physical machines and infrastructure that host the Oracle RDS instances are designed to withstand failure in the vent of a catastrophe. Here, the instance is designed to fail safe by automatically performing complete failover operations making new database operations possible after the failure has occurred. One important advantage with Oracle RDS instances is that they do not require manual intervention when failure occurs all the instances remain the same after the failure has occurred.
Services can be migrated from one hosting solution to the other because the process is easy and less disruptive. However, when migrating to new environments that are supported by any version of Oracle RDS, upgrades must be done on the data being migrated to a different environment to ensure consistence with the new environment.
How good is RDS Oracle?
Oracle RDS is easy to set up because it has features that enable the DBA to carry out automated data backups and disaster recovery. In addition, the RDS enables the database administrator to monitor the database for signs of failure from remote locations. The RDS enables push button scalability and provides failure detection and automatic recovery capabilities. In addition, the DBS systems administrator can use role based security privileges to monitor the systems users by granting and revoking privileges depending on the security vulnerabilities in the user environment.
When using Oracle RDS, an enterprise does not need a database administrator to manage the database because most of the services offered on the platform such as disaster recovery and upgrades are automated. In addition, PostgreSQL and MySQL engines that run on the RDS can be used to physically replicate data and place it on a standby up-to-date mode in case of failure. Here, high data and service availability are made possible if the database instances are run on Multi-AZ environments.
In case failure occurs, it lasts for only a short time and in most cases for two minutes before the system starts running again. It is possible to run database maintenance services while the database is still in use. In addition, database administrators find it easy to manage new deployment environments when running different DB instances without the need for extra resources. Here, the client receives alerts through the DB Event notification module via SMS when new database instances are deployed and automatic software patching is done.
Another advantage with RDS Oracle is that, a database administrator can use the application to convert magnetic storage to general purpose storage without causing failure or loss of availability, which can cause serious business continuity problems. Users benefit from push button scaling that allows for DB instances to be scaled in a handful of minutes in an operation that involves shutting down and starting the database. On the other hand, storage requirements can be scaled when demand for more storage space increases. Oracle RDS uses snapshots to create backups in real time so that failure instances can be ameliorated by use of the backup files.
