Week 2 Worklog

Master Amazon EC2 lifecycle: From AMI selection to SSH connectivity.
Implement Defense in Depth: Differentiating Security Groups vs. Network ACLs (NACL).
Gain industry insights on AI/Data trends via Cloud Day.

Day	Task	Start Date	Completion Date	Reference Material
2	- Theory: Analyzed EC2 Instance families (General Purpose vs. Compute Optimized) and processor architectures (Intel vs. AWS Graviton). - Cryptography: Deep dive into asymmetric encryption (Key Pairs) for secure SSH access.	09/15/2025	09/16/2025	REFER HERE
3	- Provisioning: Launched EC2 Instances (Ubuntu/Amazon Linux 2) within Public Subnets. - Security Layering: + Configured Security Groups (Stateful Firewall) at the Instance level. + Configured NACLs (Stateless Firewall) at the Subnet level for traffic filtering.	09/16/2025	09/17/2025	REFER HERE
4	- Troubleshooting: Debugged “Connection Time Out” errors (root caused by missing Route Table entries or SG rules). - Handled account verification requests to increase Service Quotas.	09/17/2025	09/20/2025	REFER HERE
5	- Event: Attended AWS Cloud Day. - Insight: Explored Generative AI (Amazon Bedrock) use cases and Enterprise Data Analytics strategies.	09/18/2025	09/18/2025

Gained foundational knowledge of VPC and EC2, including their core concepts and configurations.
Understood the necessary steps and resources required to launch an EC2 instance.
Successfully provisioned the first compute resources and established secure remote access.
Conceptualized the Security Layering model: NACL as the “Neighborhood Gate” (Subnet) vs. Security Group as the “Building Guard” (Instance).
Broadened perspective on modern Cloud trends (GenAI/Data) to inform future architectural decisions.
