- Learned CloudWatch fundamentals for monitoring AWS resources
Team Collaboration:
- Successfully proposed ideas and assigned tasks for project proposal
- Team is prepared to begin implementation phase
- Established clear roles and responsibilities for each team member
Workshop Progress - VPC & Network Setup:
- Created VPC with CIDR
10.0.0.0/16 in ap-southeast-1 region - Designed subnet architecture: Public subnets (10.0.1.0/24, 10.0.2.0/24) and Private subnets for App (10.0.11.0/24, 10.0.12.0/24) and DB (10.0.21.0/24, 10.0.22.0/24) across two AZs
- Configured Internet Gateway for public subnet internet access
- Set up route tables for proper traffic routing
- Began security group configuration for multi-tier architecture
Key Takeaways:
- Transit Gateway is essential for managing complex multi-VPC architectures
- EC2 Auto Scaling ensures applications can handle variable load efficiently
- Lightsail is perfect for simple workloads without AWS complexity
- Migration services provide multiple paths for moving workloads to AWS
- VPC design with separate public/private subnets provides security isolation
- Multi-AZ deployment ensures high availability from the network layer
