What is Amazon S3?
Amazon S3, short for Simple Storage Service, is a popular cloud storage service provided by Amazon Web Services (AWS). It’s like an online hard drive where you can store files such as images, documents, videos, backups, and more—and access them anytime over the internet.
Whether you’re running a small blog or a big app, S3 helps you save your files securely and reliably without worrying about storage space or hardware.
How Does S3 Work?
S3 stores your files as objects inside buckets. Here’s what those mean in simple terms:
- Bucket: A container to hold your files (think of it like a folder).
- Object: The actual file (image, video, text file, etc.).
- Key: The unique name you give to each object (like a filename).
- Region: Where your bucket is located (you can choose a location closer to your users).
Example: If you upload a photo to a bucket named my-blog-images, the object (photo) is stored in that bucket and can be accessed using a unique link.
