AWS S3 Object Storage Part One: Fundamentals & Security

Just covered Part One of AWS S3 Object Storage in our Cloud Practitioner series - diving deep into fundamentals and security! What we learned: • S3 Overview: 99.999999999% (11 9's) durability, virtually unlimited storage, 0 bytes to 5TB objects • S3 Use Cases: Backup & archival, static websites, data lakes, content distribution, disaster recovery • S3 Fundamentals: Globally unique bucket names, regional resources, objects with keys/values/metadata • Security Deep Dive: IAM policies vs bucket policies vs ACLs - three layers of access control • Block Public Access Settings: Four guardian controls to prevent accidental public exposure • Encryption Options: SSE-S3 (default), SSE-KMS (customer control), SSE-C (customer keys) • Static Website Hosting: Cost-effective hosting with automatic scaling • S3 Versioning: Protect against deletion, preserve history, enable replication features Key security takeaway: S3 is private by default - use IAM policies for internal users, bucket policies for cross-account access, and enable all Block Public Access settings unless public access specifically needed. Perfect for introduction to S3 security and AWS Cloud Practitioner exam prep! #aws #s3 #objectstorage #awssecurity #cloudpractitioner #awscertification #encryption
