AWS has been taking up centre stage for business-critical applications, meanwhile Oracle Database happens to see a lot of investment because of it being a popular relational database management system (RDBMS). With AWS being the leader in Cloud services, moving your Oracle DB to AWS is an obvious choice. There are a lot of applications and databases that require 24/7 availability and one of the most efficient methods with minimal downtime is by using Database Migration Service (DMS). With an active AWS account, on-premise Oracle Database, and an Amazon (Relational Database Service) RDS and Oracle DB instance you can transfer a database of size 64 TB.

Data migration to the cloud can be achieved for as low as $3 for terabyte-sized data. For small data (200 MB), the easy solution is Oracle SQL Developer database copy. However, a few factors like the high cost of licensing or the lack of integration between Oracle and AWS native services, make the transition somewhat challenging. Therefore, you must grasp the basics of Oracle DB to AWS environment minutely before migration.

The ‘lift and shift’ of an Oracle database has 3 steps, including migration, testing and validation, along with continuous management and maintenance.

  • Migration: The first step is when your data is transferred to an S3 bucket using Oracle Data Pump Utility, to further move it to the RDS instance.
  • Testing and validation: Testing the performance of your database on AWS is essential to ensure that it meets your (Service Level Agreement) SLAs. After testing you can also utilize AWS data pipeline services to move your data among different AWS resources.
  • Management and maintenance: This includes connectivity, security, backup, recovery, capacity planning, monitoring and troubleshooting.

Apart from improving its scalability and reliability, AWS is also popular among clients for reducing costs up to 60%, improving the latency of around 40% and reducing database admin overhead by over 70%. Oracle databases, being a standard workload, are often moved to AWS to make the business future-proof.
