We would recommend starting with AWS – Associate Solutions Architect training/certification
There is a lot of foundation skills needed to make AWS work efficiently for you so I would definitely start there.
Amazon’s cloud is called AWS which stands for Amazon Web Services and their database offering is called RDS or Relational Database Service.
Currently, there are NO database specific certifications for Amazon’s RDS platform.
The code, applications, and TOOLS (like Management Studio) you already use today with your existing databases can be used with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period and enabling point-in-time recovery.
Amazon RDS makes it easy to use replication to enhance availability and reliability for production workloads. Using the Multi-AZ deployment option you can run MISSION CRITICAL workloads with high availability and built-in automated fail-over from your primary database to asynchronously replicated secondary database in case of a failure.
Availability zone replication is very much like having a built-in SQL Server Cluster with the click of a button. This course will set up SQL Server Availability Zones for our HIGH AVAILABILITY needs.
Once a database is migrated onto cloud as relational data service RDS as they call it in AWS RDS, migration onto Amazon Aurora the primary market AWS is aiming for by providing data migration tool that makes migration easy using GUI, wherein all the database objects can be validated while migration is tested, AWS aims at making Oracle database to Amazon Aurora Migration possible as a piece of cake. This does apply to MySQL which is again owned by Oracle Corporation. Coming to the Oracle, MySQL dba job threat not everyone will be laid off, but at least half of the team can be eliminated as much of the administration is 100% automated at cloud level. So, Oracle DBA should again start looking at positive side of it to see how they can equip themselves with needed skills for the sustenance of their jobs
