Week 3 Worklog

Week 3 Objectives:

  • Implement comprehensive monitoring and observability strategies using Amazon CloudWatch (Metrics, Logs, Alarms, Dashboards).
  • Establish Hybrid DNS architectures to integrate on-premises networks with AWS using Route 53 Resolver and Microsoft Active Directory.
  • Achieve proficiency in AWS CLI for advanced resource management (Infrastructure as Code basics) and automation across Storage, Networking, Identity, and Compute services.

AWS re:Invent 2019: Introduction to the AWS CLI v2

Week 3 Achievements

Observability & Monitoring

  • Successfully deployed a monitoring stack using Amazon CloudWatch.
  • Created custom Dashboards to visualize critical metrics (CPU, Memory, Disk I/O) in real-time.
  • Configured CloudWatch Alarms to trigger automated notifications via SNS when thresholds were breached.
  • Mastered Logs Insights to query and analyze application log data effectively.

Hybrid Networking

  • Designed and implemented a Hybrid DNS solution bridging on-premises and cloud environments.
  • Deployed Microsoft Active Directory on AWS and integrated it with Route 53.
  • Configured Route 53 Resolver Endpoints (Inbound/Outbound) and Forwarding Rules to resolve domain names across the hybrid network.
  • Verified secure connectivity using Remote Desktop Gateway (RDGW).

Advanced Infrastructure Management (CLI)

  • Transitioned from Console-based management to Command Line Interface (CLI) operations.
  • Automating resource provisioning:
    • Storage: Created S3 buckets and managed object lifecycles/uploads.
    • Security: Managed IAM users, policies, and practiced Assuming Roles for cross-account access.
    • Networking: Built a complete VPC stack (VPC, Subnets, IGW, Route Tables) using CLI commands.
    • Compute: Launched EC2 instances with user-data scripts via CLI.
  • Gained troubleshooting skills for CLI configuration, credential management (MFA/SAML), and API error handling.
