Week 1 Worklog

Week 1 Objectives:

Understand the fundamentals of cloud computing and AWS global infrastructure.
Learn how to manage AWS services using Management Console, CLI, and SDK.
Explore AWS security, IAM, and cost management through practical labs.
Build foundational knowledge of VPC networking and connectivity (Subnets, Route Tables, IGW, NAT, Peering, Transit Gateway).
Gain hands-on experience by performing AWS labs to reinforce theoretical knowledge with practical skills.

Tasks to be carried out this week:

Day	Task	Start Date	Completion Date	Reference Material
1	AWS Cloud Foundation & IAM Security - Cloud Essentials: Researched core cloud computing concepts and AWS Global Infrastructure (Regions, AZs, Edge Locations). - Account Management: Explored AWS Pricing models and Support Plans. - Hands-on Lab: Secured Root User, configured IAM (Users, Groups, MFA), and set up cost alerts using AWS Budgets.	08/09/2025	08/09/2025	Module 01
2	Networking Fundamentals (VPC Architecture) - VPC Design: Analyzed Amazon VPC architecture, IP addressing (CIDR Blocks), and Subnet segmentation (Public/Private). - Routing Components: Studied routing mechanisms via Route Tables, Internet Gateway (IGW), and NAT Gateway. - Network Interfaces: Researched Elastic IP (EIP), ENI, and VPC Endpoints (Gateway & Interface) for optimized internal connectivity.	09/09/2025	09/09/2025	Module 02
3	Network Security & Advanced Connectivity - Network Security: Compared Instance-level security (Security Groups) vs. Subnet-level security (Network ACLs); monitored traffic with VPC Flow Logs. - Inter-Connectivity: Explored multi-VPC connection models (VPC Peering, Transit Gateway) and hybrid connectivity (VPN, Direct Connect). - Load Balancing: Studied application traffic distribution using Elastic Load Balancing (ELB) (ALB, NLB, GWLB).	10/09/2025	10/09/2025	Module 02
4	Hands-on Lab: VPC Infrastructure Implementation - Infrastructure Setup: Deployed a standard VPC model: Created Subnets, IGW, Route Tables, and Security Groups. - Compute & Connectivity: Launched EC2 Instances and configured NAT Gateway for secure Private Subnet internet access. - Operations: Practiced resource monitoring via CloudWatch and secure session management using SSM Session Manager.	11/09/2025	11/09/2025	Module 02
5	Hands-on Lab: Advanced Networking Scenarios - Secure Access: Practiced Port Forwarding techniques and centralized log management with Session Manager. - VPC Peering: Configured cross-Region/Account VPC peering connections and updated route tables. - Transit Gateway: Implemented a centralized Hub-and-Spoke network model to simplify routing. - Hybrid DNS: Configured Route 53 Resolver (Inbound/Outbound Endpoints) for hybrid domain resolution.	12/09/2025	12/09/2025	Module 02

Week 1 Achievements:

- Learned AWS global infrastructure (Regions, AZs, Edge Locations, Data Centers).
Hands-on with AWS management tools
- Practiced with AWS Management Console, AWS CLI, and AWS SDK.
- Created and managed IAM Users/Groups, enabled MFA, and configured Access Keys.
Cost management & support
- Created and configured different AWS Budgets.
- Learned AWS Support Plans and practiced opening support cases.
AWS Networking & Security
- Built and configured VPC, Subnet, Route Table, Internet Gateway, NAT Gateway.
- Implemented Security Groups, Network ACLs, and VPC Flow Logs.
- Understood VPC Peering vs. Transit Gateway, and hybrid connectivity (VPN, Direct Connect).
System management on AWS
- Managed EC2 instances with Session Manager instead of SSH.
- Practiced Port Forwarding and Session Logs.
- Enabled CloudWatch Monitoring & Alerts for EC2.
Advanced solutions
- Set up VPC Peering and Transit Gateway for multi-VPC connectivity.
- Configured Hybrid DNS with Route 53 Resolver (Inbound/Outbound Endpoints).
- Practiced Elastic Load Balancer (ALB, NLB, CLB, GWLB).

👉 Outcome: After Week 1, I have built a strong foundation in AWS fundamentals and intermediate networking concepts, while successfully completing multiple hands-on labs directly on AWS to strengthen my practical skills.
