1. Understanding Cloud Storage
Cloud storage is like having a massive, secure hard drive in the sky. It allows you to store data on the internet through a cloud computing provider who manages and operates data storage as a service. With cloud storage, you can access your files, databases, or backups from anywhere with an internet connection.
Key Concepts:
- Data is stored on remote servers rather than local devices
- Accessibility from multiple devices and locations
- Scalability to accommodate growing data needs
- Managed by a service provider, reducing maintenance overhead

Example:
A healthcare provider uses Glacier Deep Archive to store patient records that must be kept for decades due to regulatory requirements.
Best Practices:
- Carefully consider retrieval needs when choosing between Glacier and Deep Archive
- Use vault lock policies to enforce compliance controls
- Implement data lifecycle management to automate the archival process
4.5 AWS Storage Gateway
What It Is:
AWS Storage Gateway is a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage. It's like having a portal that connects your local environment to AWS storage services.
