AWS Relational Databases

• In General there are two broader approaches for databases in AWS
  • Managed Databases (Database as a Service):
    • AWS Manages
      • Database setups
      • Replications according to your configurations
      • Backups according to your configurations
      • Scaling:
        • Storage (Disk)
        • Sizing (CPU and RAM)
    • What we Manage: Our Data and connections
    • Supported Databases:
      • Microsoft SQL Server
      • Oracle
      • Postgres
      • mysql
      • mariadb
    • In the supported Databases there are few supported versions
  • UnManaged Databases:
    • Here AWS will give an Virtual Machine (EC2 instance) with pre-installed databases or you can install
    • Here you can select preinstalled Databases with AWS Market place and there can be hourly licensing costs extra to ec2 charges
