Security and Best Practices

Access Control

Secure Your S3 Storage

• Strong Credentials - Use complex access keys and rotate them regularly
• Least Privilege - Only grant necessary permissions
• Secure Storage - Store credentials securely (use environment variables or credential files)
• Monitor Access - Regularly review access logs
• Backup Credentials - Keep secure backup of access keys

Data Protection

Protect Your Data

# Encrypt files before upload
gpg --cipher-algo AES256 --compress-algo 1 --symmetric myfile.txt
aws s3 cp myfile.txt.gpg s3://my-bucket/ --endpoint-url https://eu-west-1.euronodes.com

# Use server-side encryption (if supported)
aws s3 cp myfile.txt s3://my-bucket/ \
    --endpoint-url https://eu-west-1.euronodes.com \
    --sse AES256

Backup Strategies

Backup Best Practices

• 3-2-1 Rule - 3 copies, 2 different media types, 1 offsite
• Regular Testing - Test restore procedures regularly
• Version Control - Keep multiple versions of important files
• Documentation - Document your backup procedures
• Automation - Automate backups to ensure consistency

Integration Examples

Programming Languages

SDK Examples

Python (boto3)

import boto3

# Configure S3 client
s3 = boto3.client('s3',
    endpoint_url='https://eu-west-1.euronodes.com',
    aws_access_key_id='YOUR_ACCESS_KEY',
    aws_secret_access_key='YOUR_SECRET_KEY'
)

# Upload file
s3.upload_file('local_file.txt', 'my-bucket', 'remote_file.txt')

# Download file
s3.download_file('my-bucket', 'remote_file.txt', 'downloaded_file.txt')

# List objects
response = s3.list_objects_v2(Bucket='my-bucket')
for obj in response.get('Contents', []):
    print(obj['Key'])

Node.js (AWS SDK)

const AWS = require('aws-sdk');

// Configure S3
const s3 = new AWS.S3({
    endpoint: 'https://eu-west-1.euronodes.com',
    accessKeyId: 'YOUR_ACCESS_KEY',
    secretAccessKey: 'YOUR_SECRET_KEY',
    s3ForcePathStyle: true
});

// Upload file
const uploadParams = {
    Bucket: 'my-bucket',
    Key: 'file.txt',
    Body: 'Hello World!'
};

s3.upload(uploadParams, (err, data) => {
    if (err) console.log(err);
    else console.log('Upload successful:', data.Location);
});

    --endpoint-url https://eu-west-1.euronodes.com \
    --cli-write-timeout 0

FAQ

What's the difference between S3 and regular file storage?

S3 is object storage designed for backups and archival, while regular file storage is for active file systems. S3 is more cost-effective for large amounts of data.

Can I use any S3-compatible tool?

Yes, our S3 storage is fully compatible with the S3 API, so any tool that works with Amazon S3 will work with Euronodes S3.

How secure is my data in S3 storage?

Data is encrypted in transit and at rest. You can add additional encryption by encrypting files before upload.

Are there any bandwidth limits?

Check your service plan for specific bandwidth allocations. Most plans include generous bandwidth allowances.

Can I access my S3 storage from multiple locations?

Yes, S3 storage can be accessed from anywhere with internet connectivity using your access credentials.

What are the bucket naming requirements?

Bucket names must be lowercase, 3-63 characters, start/end with letter or number, and contain only letters, numbers, and hyphens.
