ACHIEVEMENTS IN WEEK 6:

  1. Successfully implemented automated cost-saving solution (Lab 13): Used Lambda to Stop/Start EC2 instances on schedule and integrated Slack notifications.
  2. Built a Serverless image processing application (Lab 14): Combined Lambda, S3, and DynamoDB to automatically resize images and store metadata.
  3. Completed the detailed Solution Architecture design and Cost Estimation for the final capstone project.
  4. Expanded knowledge on Data Science on AWS platform through the specialized workshop.
  5. Proficiently used AWS CLI (Lab 15) to manipulate core services (S3, EC2, VPC, IAM) without using the Console interface.
