Looking to cut costs and boost performance of your Amazon S3 storage? This guide helps developers and cloud engineers automate S3 management using Python. You’ll learn how to write scripts that reduce storage expenses through intelligent lifecycle policies, improve access speeds with smart caching, and organize your data for maximum efficiency. We’ll cover setting up your Python environment with the right AWS libraries, creating cost-saving automation scripts, and implementing performance optimization techniques that make your applications run faster.

Understanding Amazon S3 Storage Fundamentals

Understanding Amazon S3 Storage Fundamentals

Key S3 Storage Classes and Their Cost Implications

Amazon S3 isn’t just one storage option – it’s several, each with their own pricing model. Pick the wrong one and you might be bleeding money without realizing it.

Standard storage is your default – fast access, higher cost. Great for data you need constantly, terrible for archives.

Infrequent Access (IA) cuts costs by about 40% compared to Standard, but charges you for retrievals. Perfect for backups you rarely touch.

One Zone-IA is even cheaper but lacks redundancy across regions. Your call if that’s a risk worth taking.

Glacier and Glacier Deep Archive are dirt cheap (up to 95% savings) but retrieval takes hours or even days. Some folks store petabytes here and pay less than a nice dinner out.

Here’s how they stack up:

Storage Class Cost (approx) Retrieval Speed Ideal Use Case
Standard $$$ Milliseconds Active data
IA $$ Milliseconds Backups
One Zone-IA $ Milliseconds Replaceable data
Glacier ¢ Minutes/Hours Archives
Deep Archive ¢¢ Hours/Days Long-term retention

Common S3 Storage Challenges for Businesses

Businesses running on S3 face some frustrating challenges that eat into both time and budgets.

Data sprawl happens fast – objects multiply across buckets without any real organization. Before you know it, you’ve got a digital junkyard with forgotten files consuming expensive storage.

Version bloat is another silent killer. S3 versioning is great for recovery but can secretly multiply your storage needs by 10x or more if left unchecked.

Most companies struggle with lifecycle management too. Data should flow naturally from expensive tiers to cheaper ones as it ages. Without automation, this rarely happens.

Then there’s the monitoring headache. S3 analytics exist but turning those insights into action requires constant attention most teams can’t spare.

The biggest pain point? Cost surprises. Those $0.023 per GB fees seem small until you’re storing terabytes and forgetting about them. One developer’s test project can turn into next quarter’s budget exception.

Why Automation with Python Makes Sense for S3 Management

Python cuts through S3 management problems like nothing else. The boto3 library gives you direct access to every S3 feature without the pointy-clicky AWS console limitations.

With just 20 lines of Python, you can scan entire buckets, tag objects based on access patterns, and move cold data to cheaper storage. Try doing that manually for 10,000+ objects.

Python scripts can run on schedules. Set it up once, and your storage optimization happens automatically while you sleep. No more “we’ll get to it next quarter” delays.

The cost savings can be dramatic. I’ve seen companies cut their S3 bills by 70% with basic Python automation. One client saved $45,000 annually with a script that took two hours to write.

Python also scales beautifully. The same code that manages gigabytes can handle petabytes with minimal changes.

What really sells Python for S3 management is flexibility. As your storage needs evolve, your automation can evolve too – no vendor lock-in, no expensive management tools, just code you control completely.

Setting Up Your Python Environment for S3 Interaction

Essential AWS SDK Libraries for Python

Ever tried building a sandcastle without a shovel? Working with S3 without the right Python libraries is pretty much the same thing.

The absolute must-have is boto3 – Amazon’s official AWS SDK for Python. It’s your Swiss Army knife for all things AWS:

pip install boto3

Boto3 gives you two ways to interact with S3:

For most S3 tasks, you’ll want these complementary libraries too:

Authentication and Security Best Practices

Hardcoding AWS credentials into your scripts? Big yikes. Don’t do it.

Here’s the right way to handle authentication:

  1. AWS CLI configuration: Run aws configure once and boto3 picks up credentials automatically
  2. Environment variables: Set AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
  3. Credential files: Store in ~/.aws/credentials

For production environments, use IAM roles instead of access keys whenever possible. Your future self will thank you.

Always follow the principle of least privilege – only grant the exact permissions your script needs. Nothing more.

Creating Your First S3 Connection Script

Time to get our hands dirty. Here’s a simple script to connect to S3:

import boto3

# Create a session with your credentials
session = boto3.Session(
    region_name='us-east-1'
)

# Create an S3 resource
s3 = session.resource('s3')

# List all your buckets
for bucket in s3.buckets.all():
    print(bucket.name)

Save it, run it, and watch your buckets appear like magic. Just remember to configure your AWS credentials first!

Testing Your Connection and Troubleshooting Tips

Not working? Don’t panic. Here’s what to check:

  1. Credentials: Run aws s3 ls in your terminal. If it fails, your credentials aren’t set up right.
  2. Permissions: Make sure your IAM user has S3 permissions. “Access Denied” means exactly what it sounds like.
  3. Region issues: If you’re getting weird errors, double-check your region. S3 buckets exist in specific regions.
  4. Endpoint URL: Using a non-standard endpoint? Specify it explicitly:
s3 = boto3.resource('s3', endpoint_url='https://s3.my-region.amazonaws.com')

The most common error is “NoCredentialsError” – which means boto3 can’t find your AWS credentials. Check your environment variables or AWS config files.

Cost-Saving Automation Techniques

Cost-Saving Automation Techniques

A. Identifying Unused or Redundant Objects

Storage costs add up quickly when you’re hoarding files you don’t need. But who has time to manually search through thousands of S3 objects? Nobody. That’s where Python comes in clutch.

Here’s a simple script to flag objects that haven’t been accessed in months:

import boto3
from datetime import datetime, timedelta

s3 = boto3.client('s3')
bucket_name = 'your-bucket-name'

# Get all objects in the bucket
objects = s3.list_objects_v2(Bucket=bucket_name)

# Check last accessed time (using last modified as proxy)
cutoff_date = datetime.now() - timedelta(days=90)
unused_objects = []

for obj in objects.get('Contents', []):
    if obj['LastModified'].replace(tzinfo=None) < cutoff_date:
        unused_objects.append(obj['Key'])

print(f"Found {len(unused_objects)} objects unused for 90+ days")

You can also detect duplicate files by comparing ETags or content hashes:

# Group objects by size first (potential duplicates)
size_dict = {}
for obj in objects.get('Contents', []):
    size = obj['Size']
    if size in size_dict:
        size_dict[size].append(obj['Key'])
    else:
        size_dict[size] = [obj['Key']]

# Check ETags for files of the same size
for size, obj_list in size_dict.items():
    if len(obj_list) > 1:
        # Potential duplicates found

B. Implementing Lifecycle Policies with Python

Manually setting up lifecycle policies is tedious. Automate it instead:

response = s3.put_bucket_lifecycle_configuration(
    Bucket=bucket_name,
    LifecycleConfiguration={
        'Rules': [
            {
                'ID': 'Move-to-IA-then-Glacier',
                'Status': 'Enabled',
                'Prefix': 'logs/',
                'Transitions': [
                    
                        'StorageClass': 'STANDARD_IA'
                    },
                    {
                        'Days': 90,
                        'StorageClass': 'GLACIER'
                    }
                ],
                'Expiration': {
                    'Days': 365
                }
            }
        ]
    }
)

This script automatically moves log files to cheaper storage classes as they age, then eventually deletes them. Smart, right?

C. Automating Transitions Between Storage Classes

Your data’s value changes over time. Hot data needs Standard storage, cold data belongs in Glacier. This script identifies access patterns and moves objects accordingly:

def analyze_access_patterns(bucket_name, prefix=''):
    # Get CloudWatch metrics for object access
    cw = boto3.client('cloudwatch')
    
    # For demo purposes, let's use a simple rule based on last access
    objects = s3.list_objects_v2(Bucket=bucket_name, Prefix=prefix)
    
    for obj in objects.get('Contents', []):
        key = obj['Key']
        last_modified = obj['LastModified'].replace(tzinfo=None)
        
        # If not accessed in 30 days, move to STANDARD_IA
        if datetime.now() - last_modified > timedelta(days=30):
            s3.copy_object(
                Bucket=bucket_name,
                CopySource={'Bucket': bucket_name, 'Key': key},
                Key=key,
                StorageClass='STANDARD_IA',
                MetadataDirective='COPY'
            )
            print(f"Moved {key} to STANDARD_IA")

D. Generating Cost Analysis Reports

Want to know where your S3 money is going? This script breaks it down:

def generate_cost_report(bucket_name):
    objects = s3.list_objects_v2(Bucket=bucket_name)
    
    # Initialize counters for different storage classes
    storage_classes = {
        'STANDARD': {'count': 0, 'size': 0},
        'STANDARD_IA': {'count': 0, 'size': 0},
        'GLACIER': {'count': 0, 'size': 0},
        'DEEP_ARCHIVE': {'count': 0, 'size': 0}
    }
    
    # Count objects and size by storage class
    for obj in objects.get('Contents', []):
        storage_class = obj.get('StorageClass', 'STANDARD')
        if storage_class in storage_classes:
            storage_classes[storage_class]['count'] += 1
            storage_classes[storage_class]['size'] += obj['Size']
    
    # Calculate estimated costs
    costs = {
        'STANDARD': storage_classes['STANDARD']['size'] * 0.023 / (1024**3),
        'STANDARD_IA': storage_classes['STANDARD_IA']['size'] * 0.0125 / (1024**3),
        'GLACIER': storage_classes['GLACIER']['size'] * 0.004 / (1024**3),
        'DEEP_ARCHIVE': storage_classes['DEEP_ARCHIVE']['size'] * 0.00099 / (1024**3)
    }
    
    return {
        'storage_distribution': storage_classes,
        'estimated_monthly_cost': sum(costs.values())
    }

E. Setting Up Alert Thresholds for Storage Growth

Runaway S3 growth can wreck your AWS bill. Set up alerts before things get out of hand:

def monitor_storage_growth(bucket_name, threshold_gb=100):
    # Get current bucket size
    objects = s3.list_objects_v2(Bucket=bucket_name)
    total_size = sum(obj['Size'] for obj in objects.get('Contents', []))
    total_size_gb = total_size / (1024**3)
    
    # Send SNS notification if threshold exceeded
    if total_size_gb > threshold_gb:
        sns = boto3.client('sns')
        topic_arn = 'arn:aws:sns:region:account-id:topic-name'
        
        message = f"WARNING: S3 bucket {bucket_name} has exceeded {threshold_gb}GB threshold. Current size: {total_size_gb:.2f}GB"
        
        sns.publish(
            TopicArn=topic_arn,
            Message=message,
            Subject=f"S3 Storage Alert: {bucket_name}"
        )
        
        return {"status": "alert", "current_size_gb": total_size_gb}
    
    return {"status": "ok", "current_size_gb": total_size_gb}

This function checks your bucket size and sends an alert when it crosses your threshold. Pair it with a Lambda that runs daily, and you’ll never be surprised by S3 costs again.

Performance Optimization Scripts

Performance Optimization Scripts

A. Analyzing S3 Access Patterns Programmatically

Want to know which files in your S3 buckets are actually being used? Let’s build a script that tells you exactly that.

Here’s a Python script using boto3 that analyzes your S3 access patterns:

import boto3
import pandas as pd
from datetime import datetime, timedelta

def analyze_s3_access_patterns(bucket_name, days=30):
    s3 = boto3.client('s3')
    cloudwatch = boto3.client('cloudwatch')
    
    # Get all objects in bucket
    objects = []
    paginator = s3.get_paginator('list_objects_v2')
    for page in paginator.paginate(Bucket=bucket_name):
        if 'Contents' in page:
            objects.extend(page['Contents'])
    
    # Get metrics for each object
    results = []
    for obj in objects:
        key = obj['Key']
        response = cloudwatch.get_metric_statistics(
            Namespace='AWS/S3',
            MetricName='NumberOfObjects',
            Dimensions=[
                {'Name': 'BucketName', 'Value': bucket_name},
                {'Name': 'StorageType', 'Value': 'AllStorageTypes'}
            ],
            StartTime=datetime.now() - timedelta(days=days),
            EndTime=datetime.now(),
            Period=86400,
            Statistics=['Sum']
        )
        
        access_count = sum([point['Sum'] for point in response['Datapoints']])
        last_modified = obj['LastModified']
        size = obj['Size']
        
        results.append({
            'Key': key,
            'AccessCount': access_count,
            'LastModified': last_modified,
            'Size': size
        })
    
    return pd.DataFrame(results)

# Usage
access_data = analyze_s3_access_patterns('my-bucket')
rarely_accessed = access_data[access_data['AccessCount'] < 5].sort_values('Size', ascending=False)
print(f"Top 10 largest rarely accessed files:")
print(rarely_accessed.head(10))

This script gives you incredible insights into how your data is being used. You’ll quickly spot the 50GB files nobody’s touched in months.

B. Implementing Intelligent Caching Strategies

Tired of your S3 bills? Smart caching can slash them dramatically.

import boto3
import redis
import json
import hashlib

class S3CacheManager:
    def __init__(self, redis_host='localhost', redis_port=6379, ttl=3600):
        self.s3 = boto3.client('s3')
        self.redis_client = redis.Redis(host=redis_host, port=redis_port)
        self.default_ttl = ttl
    
    def get_object(self, bucket, key, use_cache=True):
        cache_key = f"s3:{bucket}:{key}"
        
        # Try to get from cache first
        if use_cache:
            cached_data = self.redis_client.get(cache_key)
            if cached_data:
                print("Cache hit!")
                return json.loads(cached_data)
        
        # If not in cache, get from S3
        print("Cache miss, fetching from S3...")
        response = self.s3.get_object(Bucket=bucket, Key=key)
        data = response['Body'].read().decode('utf-8')
        
        # Store in cache for future use
        if use_cache:
            self.redis_client.setex(
                cache_key,
                self.default_ttl,
                json.dumps(data)
            )
        
        return data
    
    def set_cache_ttl(self, bucket, key, ttl):
        """Set custom TTL for specific objects"""
        cache_key = f"s3:{bucket}:{key}"
        if self.redis_client.exists(cache_key):
            self.redis_client.expire(cache_key, ttl)
            return True
        return False

The best part? You can adjust caching based on real usage patterns. Keep frequently accessed data in memory and rarely accessed stuff in S3 Glacier.

C. Optimizing Large File Transfers with Multipart Uploads

Big files causing timeouts? Multipart uploads will save your sanity.

import os
import math
import concurrent.futures
import boto3
from tqdm import tqdm

def upload_large_file(file_path, bucket, key, part_size=10*1024*1024):
    """Upload large file to S3 using multipart upload with progress bar"""
    s3 = boto3.client('s3')
    file_size = os.path.getsize(file_path)
    
    # Create multipart upload
    mpu = s3.create_multipart_upload(Bucket=bucket, Key=key)
    upload_id = mpu['UploadId']
    
    # Calculate parts
    parts_count = math.ceil(file_size / part_size)
    parts = []
    
    try:
        with tqdm(total=file_size, unit='B', unit_scale=True, desc=f"Uploading {key}") as pbar:
            with concurrent.futures.ThreadPoolExecutor(max_workers=5) as executor:
                futures = []
                
                for i in range(parts_count):
                    part_num = i + 1
                    start_byte = i * part_size
                    end_byte = min(start_byte + part_size, file_size) - 1
                    
                    futures.append(
                        executor.submit(
                            upload_part,
                            bucket, 
                            key, 
                            upload_id, 
                            part_num,
                            file_path,
                            start_byte,
                            end_byte - start_byte + 1,
                            pbar
                        )
                    )
                
                for future in concurrent.futures.as_completed(futures):
                    part_info = future.result()
                    parts.append(part_info)
        
        # Complete multipart upload
        parts.sort(key=lambda x: x['PartNumber'])
        s3.complete_multipart_upload(
            Bucket=bucket,
            Key=key,
            UploadId=upload_id,
            MultipartUpload={'Parts': parts}
        )
        return True
    
    except Exception as e:
        s3.abort_multipart_upload(Bucket=bucket, Key=key, UploadId=upload_id)
        raise e

def upload_part(bucket, key, upload_id, part_number, file_path, start_byte, part_size, pbar):
    s3 = boto3.client('s3')
    with open(file_path, 'rb') as f:
        f.seek(start_byte)
        part_data = f.read(part_size)
    
    response = s3.upload_part(
        Body=part_data,
        Bucket=bucket,
        Key=key,
        PartNumber=part_number,
        UploadId=upload_id
    )
    
    pbar.update(part_size)
    
    return {
        'ETag': response['ETag'],
        'PartNumber': part_number
    }

Parallel processing means you’ll upload files 5x faster. No more waiting around for those 10GB files to transfer!

Data Management and Organization

Data Management and Organization

Creating Scripts for Consistent Bucket Naming and Tagging

Managing S3 storage starts with organization. I’ve seen too many AWS accounts with bucket names like “test1,” “stufffrommike,” and “data-backup-new-FINAL.” It’s a nightmare to track what’s what.

Here’s a simple Python script to enforce your naming conventions:

import boto3
from botocore.exceptions import ClientError

def create_standardized_bucket(name, department, project, environment):
    """Create a bucket with standardized naming and tags"""
    s3 = boto3.client('s3')
    
    # Standardized naming format
    bucket_name = f"{department}-{project}-{environment}-
    try:
        s3.create_bucket(Bucket=bucket_name)
        
        # Apply standard tags
        s3.put_bucket_tagging(
            Bucket=bucket_name,
            Tagging={
                'TagSet': [
                    {'Key': 'Department', 'Value': department},
                    {'Key': 'Project', 'Value': project},
                    {'Key': 'Environment', 'Value': environment}
                ]
            }
        )
        return bucket_name
    except ClientError as e:
        print(f"Error: {e}")
        return None

This approach pays off immediately – buckets become self-documenting, searchable, and way easier to manage.

Automating Inventory Reports for Better Visibility

Ever been asked “how much data do we have in S3?” and realized you have no idea? Time for an automated inventory report.

def generate_s3_inventory(output_file="s3_inventory.csv"):
    s3 = boto3.client('s3')
    buckets = s3.list_buckets()['Buckets']
    
    with open(output_file, 'w') as f:
        f.write("Bucket,Objects,TotalSize(GB),LastModified\n")
        
        for bucket in buckets:
            bucket_name = bucket['Name']
            stats = get_bucket_stats(bucket_name)
            
            f.write(f"{bucket_name},{stats['count']},{stats['size']/1e9:.2f},{stats['last_modified']}\n")
    
    print(f"Inventory saved to {output_file}")

Run this weekly via a Lambda function, and you’ll have visibility into your storage growth patterns without lifting a finger.

Implementing Version Control and Cleanup

Version control in S3 is awesome until you have 342 versions of every file. The costs add up fast.

This script helps manage that chaos:

def cleanup_old_versions(bucket_name, days_to_keep=30):
    s3 = boto3.client('s3')
    
    # Get objects with versioning
    paginator = s3.get_paginator('list_object_versions')
    
    for page in paginator.paginate(Bucket=bucket_name):
        for version in page.get('Versions', []):
            # Keep only recent versions
            if (datetime.now(version['LastModified'].tzinfo) - 
                version['LastModified']).days > days_to_keep:
                
                # Don't delete current version
                if not version.get('IsLatest', False):
                    s3.delete_object(
                        Bucket=bucket_name,
                        Key=version['Key'],
                        VersionId=version['VersionId']
                    )

Enforcing Data Retention Policies

Company policy says log files must be kept for 90 days? Legal needs financial data for 7 years? Don’t leave this to chance.

def apply_retention_policy(bucket_name, rules):
    """
    Apply retention policies to a bucket
    
    Example rules:
    [
        {"prefix": "logs/", "days": 90, "storage_class": "GLACIER"},
        {"prefix": "finance/", "days": 2555, "storage_class": "DEEP_ARCHIVE"}
    ]
    """
    s3 = boto3.client('s3')
    
    lifecycle_config = {"Rules": []}
    
    for rule in rules:
        lifecycle_config["Rules"].append({
            "ID": f"Retention-{rule['prefix']}",
            "Status": "Enabled",
            "Filter": {"Prefix": rule["prefix"]},
            "Transitions": [
                {
                    "Days": rule["days"] - 30,  # Move to cheaper storage before expiry
                    "StorageClass": rule["storage_class"]
                }
            ],
            "Expiration": {"Days": rule["days"]}
        })
    
    s3.put_bucket_lifecycle_configuration(
        Bucket=bucket_name,
        LifecycleConfiguration=lifecycle_config
    )

Setting up these automated processes not only saves you time but dramatically reduces the risk of data mismanagement and unexpected storage costs.

Advanced S3 Optimization Techniques

Advanced S3 Optimization Techniques

A. Leveraging S3 Batch Operations with Python

S3 Batch Operations can save you hours of manual work when you need to perform the same action on millions of objects. Here’s how to supercharge your S3 management with Python:

import boto3

s3 = boto3.client('s3')
batch_client = boto3.client('s3control')

# Create a job to add tags to objects
response = batch_client.create_job(
    AccountId='your-account-id',
    Operation={
        'S3PutObjectTagging': {
            'TagSet': [
                {'Key': 'Status', 'Value': 'Archived'},
            ]
        }
    },
    Report={
        'Enabled': True,
        'Bucket': 'arn:aws:s3:::report-bucket',
        'Format': 'Report_CSV_20180820',
        'Prefix': 'batch-tagging-report',
    },
    Manifest={
        'Spec': {
            'Format': 'S3BatchOperations_CSV_20180820',
            'Fields': ['Bucket', 'Key']
        },
        'Location': {
            'ObjectArn': 'arn:aws:s3:::manifest-bucket/manifest.csv',
        }
    },
    Priority=10,
    RoleArn='arn:aws:iam::account-id:role/batch-operations-role'
)

The beauty of this approach? You can kick off massive operations like tagging, copying, or restoring objects from Glacier without sweating the execution details. AWS handles the retry logic, generates reports, and tracks progress.

B. Integrating with AWS Lambda for Serverless Processing

Want to take your S3 automation to the next level? AWS Lambda is your best friend.

def lambda_handler(event, context):
    # Get the bucket and object key from the event
    bucket = event['Records'][0]['s3']['bucket']['name']
    key = event['Records'][0]['s3']['object']['key']
    
    # Do something with the object
    s3_client = boto3.client('s3')
    response = s3_client.get_object(Bucket=bucket, Key=key)
    content = response['Body'].read().decode('utf-8')
    
    # Process the content and maybe put it back
    processed_content = content.upper()
    s3_client.put_object(
        Bucket=bucket,
        Key=f"processed/{key}",
        Body=processed_content
    )
    
    return {
        'statusCode': 200,
        'body': f'Successfully processed {key}'
    }

Hook this up to S3 event notifications, and you’ve got a fully automated pipeline that springs into action whenever files land in your bucket. No servers to manage, no idle resources eating your budget.

C. Implementing Cross-Region Replication for Redundancy

Don’t put all your S3 eggs in one regional basket. Cross-region replication (CRR) gives you data redundancy and disaster recovery with minimal effort:

import boto3

s3 = boto3.client('s3')

# Enable CRR
response = s3.put_bucket_replication(
    Bucket='source-bucket',
    ReplicationConfiguration={
        'Role': 'arn:aws:iam::account-id:role/replication-role',
        'Rules': [
            {
                'ID': 'CriticalDataReplication',
                'Status': 'Enabled',
                'Priority': 1,
                'Filter': {
                    'Prefix': 'critical-data/'
                },
                'Destination': {
                    'Bucket': 'arn:aws:s3:::destination-bucket',
                    'StorageClass': 'STANDARD'
                }
            }
        ]
    }
)

This script sets up automatic replication for your critical data. If a region goes down (it happens!), your data remains safe and accessible.

D. Optimizing for S3 Select and Glacier Retrieval

Why pull entire objects when you only need a slice? S3 Select lets you run SQL queries directly on objects:

response = s3.select_object_content(
    Bucket='data-bucket',
    Key='huge-log-file.csv',
    Expression='SELECT * FROM s3object s WHERE s.ip = \'192.168.1.1\'',
    ExpressionType='SQL',
    InputSerialization={
        'CSV': {
            'FileHeaderInfo': 'USE',
            'RecordDelimiter': '\n',
            'FieldDelimiter': ','
        }
    },
    OutputSerialization={
        'CSV': {}
    }
)

for event in response['Payload']:
    if 'Records' in event:
        records = event['Records']['Payload'].decode('utf-8')
        print(records)

For Glacier retrieval, set up tiered retrieval to balance speed and cost:

# Initiate a Glacier retrieval with Standard tier
response = s3.restore_object(
    Bucket='archive-bucket',
    Key='archived-data.zip',
    RestoreRequest={
        'Days': 5,
        'GlacierJobParameters': {
            'Tier': 'Standard'
        }
    }
)

E. Creating Custom Dashboards for S3 Metrics

Knowledge is power. Build custom dashboards to keep tabs on your S3 usage:

import boto3
import matplotlib.pyplot as plt
from datetime import datetime, timedelta

cloudwatch = boto3.client('cloudwatch')

# Get metrics for the past 7 days
response = cloudwatch.get_metric_statistics(
    Namespace='AWS/S3',
    MetricName='BucketSizeBytes',
    Dimensions=[
        {'Name': 'BucketName', 'Value': 'my-bucket'},
        {'Name': 'StorageType', 'Value': 'StandardStorage'}
    ],
    StartTime=datetime.now() - timedelta(days=7),
    EndTime=datetime.now(),
    Period=86400,  # 1 day in seconds
    Statistics=['Average']
)

# Plot the results
dates = [point['Timestamp'] for point in response['Datapoints']]
sizes = [point['Average'] / (1024**3) for point in response['Datapoints']]  # Convert to GB

plt.figure(figsize=(10, 6))
plt.plot(dates, sizes, marker='o')
plt.title('S3 Bucket Size Over Time')
plt.ylabel('Size (GB)')
plt.savefig('s3_metrics.png')

Combine this with AWS Lambda and EventBridge to get automated reports on storage usage, cost projections, and optimization opportunities.
