☁️ AWS Journey – Day 8 🚀

Today was all about mastering Amazon EBS, Snapshots, and EFS through both theory and hands-on labs. 🔐💾

📚 Topics I Studied

• What is a Snapshot
• What is Amazon EBS (Elastic Block Store)
• What is Lifecycle Manager
• What is Amazon EFS (Elastic File System)

🛠️ Practical Labs Completed
✅ Launched an EC2 instance and attached an EBS volume
✅ Created an EBS snapshot, deleted the volume, and restored it from the snapshot backup
✅ Created multiple snapshots across different Availability Zones
✅ Created an encrypted EBS volume from a snapshot
✅ Performed a regional snapshot copy
✅ Explored and configured Fast Snapshot Restore
✅ Configured Amazon Data Lifecycle Manager (DLM) for snapshot automation
✅ Created a dedicated EC2 security group allowing only SSH (22) and HTTP (80)
✅ Created a dedicated EFS security group allowing access only from the EC2 security group
✅ Deployed two EC2 instances in different Availability Zones and connected them to the same EFS file system

💡 Key Learning
Snapshots provide reliable backups for EBS volumes, while EFS enables shared, scalable storage across multiple EC2 instances and Availability Zones. Proper security group design is essential for secure communication between EC2 and EFS.

Every day of this journey is strengthening my understanding of AWS architecture, storage, backup strategies, and security best practices. 🌩️🔒
