In my last post, we talked about what is AWS virtual private network and today let's talk about how to upload files from website to S3.
S3 (Simple Storage Service) is an object storage service provided by Amazon Web Services (AWS) known for its high reliability, scalability, and low latency. Uploading files from a website to S3 refers to storing files from the website using the cloud storage service S3.
Advantages and Use Cases of S3:
● High Reliability and Scalability: S3 provides highly reliable data storage, with automatic replication of data across multiple devices and data centers to prevent data loss. S3 also automatically scales storage capacity according to demand, eliminating concerns about running out of space.
● Low Latency Access: S3 features low latency, enabling fast uploading and downloading of files. This is especially important for applications that require frequent file read/write operations.
● Data Backup and Archiving: S3 serves as a solution for data backup and archiving, securely storing data in the cloud to prevent loss or damage of local data.
● Static Website Hosting: S3 can host static websites by configuring the static website hosting feature on an S3 bucket. Static files of the website can be stored directly in S3 and accessed through a URL provided by S3.
● Large-Scale Data Storage and Distribution: S3 is suitable for storing and distributing large static files like images, videos, and audio. Using S3's multipart upload and download features enables efficient handling of large files.
Steps to Upload Files from a Website to S3:
1. Create an S3 Bucket: In the AWS console, create an S3 bucket for storing uploaded files. You can configure the bucket's name, region, access permissions, etc.
2. Generate Upload Credentials: To securely upload files to S3, generate upload credentials. AWS SDK or API can be used to generate credentials that contain access keys and permissions for subsequent file upload operations.
3. Implement File Upload Feature on the Website: On the front end of the website, add a file upload feature using an HTML `<input type="file">` element or a JavaScript file upload plugin. After a user selects a file, send it to the backend server.
4. Handle File Upload on the Backend Server: After receiving the file from the user on the backend server, use AWS SDK or API to upload the file to the S3 bucket. Provide parameters like access credentials, bucket name, and file path.
5. File Upload Completion Notification: Once the file is uploaded to S3, use S3’s event notification feature to send a notification to other systems or services for further processing, such as generating thumbnails or updating a database.
