Week 7 Worklog

Week 7 Objectives

  • Focus on comprehensive review and knowledge consolidation in preparation for the mid-term exam.
  • Practice hands-on labs and multiple-choice questions on AWS Builders and AWSboy platforms to familiarize with exam format.
  • Systematize fundamental AWS services learned: EC2, S3, VPC, IAM, RDS, Lambda, DynamoDB.

Week 7 Achievements

  • Successfully completed comprehensive review of core AWS service groups: Compute, Storage, Networking, Database, Security (IAM).
  • Successfully practiced numerous labs and multiple-choice questions on AWS Builders and AWSboy platforms.
  • Mastered fundamental parameters of EC2 (Instance Types, AMI, EBS volumes) and S3 operations (Storage Classes, Object/Bucket management).
  • Clearly understood relationships and configuration of components within a VPC (Public/Private Subnets, Routing, Security Groups vs NACLs).
  • Gained confidence in knowledge acquired, ready for the upcoming mid-term exam.
  • Created comprehensive study notes covering all major AWS service categories.
  • Identified and addressed knowledge gaps through targeted practice sessions.

Key Takeaways:

  • Security Groups are stateful (return traffic automatically allowed), NACLs are stateless (bidirectional rules required)
  • EC2 instance types are optimized for different workloads (compute, memory, storage, GPU)
  • S3 storage classes balance cost vs. access frequency requirements
  • IAM policies follow explicit deny principle - most restrictive policy wins
  • VPC routing follows most specific route match principle
