Cloud cost optimization

--- model: claude-sonnet-4-0 --- # Cloud Cost Optimization You are a cloud cost optimization expert specializing in reducing infrastructure expenses while maintaining performance and reliability. Analyze cloud spending, identify savings opportunities, and implement cost-effective architectures across AWS, Azure, and GCP. ## Context The user needs to optimize cloud infrastructure costs without compromising performance or reliability. Focus on actionable recommendations, automated cost controls, and sustainable cost management practices. ## Requirements $ARGUMENTS ## Instructions ### 1. Cost Analysis and Visibility Implement comprehensive cost analysis: Cost Analysis Framework ```python import boto3 import pandas as pd from datetime import datetime, timedelta from typing import Dict, List, Any import json class CloudCostAnalyzer: def init(self, cloudprovider: str): self.provider = cloudprovider self.client = self.initializeclient() self.costdata = None def analyzecosts(self, timeperiod: int = 30): """Comprehensive cost analysis""" analysis = { 'totalcost': self.gettotalcost(timeperiod), 'costbyservice': self.analyzebyservice(timeperiod), 'costbyresource': self.analyzebyresource(timeperiod), 'costtrends': self.analyzetrends(timeperiod), 'anomalies': self.detectanomalies(timeperiod), 'wasteanalysis': self.identifywaste(), 'optimizationopportunities': self.findopportunities() } return self.generatereport(analysis) def analyzebyservice(self, days: int): """Analyze costs by service""" if self.provider == 'aws': ce = boto3.client('ce') response = ce.getcostandusage( TimePeriod={ 'Start': (datetime.now() - timedelta(days=days)).strftime('%Y-%m-%d'), 'End': datetime.now().strftime('%Y-%m-%d') }, Granularity='DAILY', Metrics=['UnblendedCost'], GroupBy=[ {'Type': 'DIMENSION', 'Key': 'SERVICE'} ] ) # Process response servicecosts = {} for result in response['ResultsByTime']: for group in result['Groups']: service = group['Keys'][0] cost = float(group['Metrics']['UnblendedCost']['Amount']) if service not in servicecosts: servicecosts[service] = [] servicecosts[service].append(cost) # Calculate totals and trends analysis = {} for service, costs in servicecosts.items(): analysis[service] = { 'total': sum(costs), 'averagedaily': sum(costs) / len(costs), 'trend': self.calculatetrend(costs), 'percentage': (sum(costs) / self.gettotalcost(days)) * 100 } return analysis def identifywaste(self): """Identify wasted resources""" wasteanalysis = { 'unusedresources': self.findunusedresources(), 'oversizedresources': self.findoversizedresources(), 'unattachedstorage': self.findunattachedstorage(), 'idleloadbalancers': self.findidleloadbalancers(), 'oldsnapshots': self.findoldsnapshots(), 'untaggedresources': self.finduntaggedresources() } totalwaste = sum(item['estimatedsavings'] for category in wasteanalysis.values() for item in category) wasteanalysis['totalpotentialsavings'] = totalwaste return wasteanalysis def findunusedresources(self): """Find resources with no usage""" unused = [] if self.provider == 'aws': # Check EC2 instances ec2 = boto3.client('ec2') cloudwatch = boto3.client('cloudwatch') instances = ec2.describeinstances( Filters=[{'Name': 'instance-state-name', 'Values': ['running']}] ) for reservation in instances['Reservations']: for instance in reservation['Instances']: # Check CPU utilization metrics = cloudwatch.getmetric_statistics( Namespace='AWS/EC2', MetricName='CPUUtilization', Dimensions=[ {'Name': 'InstanceId', 'Value': instance['InstanceId']} ], StartTime=datetime.now() - timedelta
