Hands-On Practice

  1. Create an RDS Instance
  • Use the AWS Management Console to create an RDS instance under the Free Tier.
  • Connect to the database using a client like MySQL Workbench or pgAdmin.
  • Execute basic SQL queries to interact with your database.
  • Clean up by deleting the instance after completion.
  1. Set Up DynamoDB
  • Create a DynamoDB table using the AWS Console.
  • Insert sample data and perform Query and Scan operations.
  • Use AWS SDKs or CLI to automate table interactions.
  • Clean up by deleting the table after completion.
  1. Explore Multi-AZ and Read Replicas
  • Set up an RDS instance with Multi-AZ deployment for high availability.
  • Create a read replica to improve read performance.
  1. Integrate DynamoDB with Lambda
  • Create an AWS Lambda function to interact with a DynamoDB table.
  • Use the function to insert and retrieve data.

Key Concepts

  1. DBaaS Definition
  • A managed cloud service where the cloud provider handles backend setup, maintenance, and scaling of databases.
