Cloud Auditor

A high-performance cloud auditing backend for AWS & Azure. It automates cost savings and security checks using a custom, concurrent Python framework to analyze massive workloads in real-time.

Executive Overview

Enterprise infrastructures spanning Amazon Web Services (AWS) and Microsoft Azure frequently suffer from billing sprawl, orphaned resources, and degraded security postures. Traditional monolithic monitoring suites introduce high processing overhead and delayed alerting cycles. Cloud Auditor was architected from the ground up as a high-throughput, asynchronous Python micro-engine designed to interrogate multi-cloud environments in real time without third-party instrumentation bloat.

By engineering a custom concurrent scanning pipeline using Python's ThreadPoolExecutor and optimized SDK calls (boto3 and Azure SDK), the tool processes thousands of resource descriptors per minute with minimal memory footprint and zero rate-limiting contention.

Architectural Challenge: Multi-Cloud Concurrency at Scale

Cloud API endpoints enforce rigorous API rate limits and structural throttling. Querying thousands of EC2 instances, EBS snapshots, Azure Virtual Networks (VNets), and Blob Storages sequentially creates unacceptable execution latencies.

To overcome this, Cloud Auditor deploys a Custom Object-Oriented Framework that decouples API discovery from rules-based evaluation:

  • Asynchronous Discovery Pool: Manages worker thread allocation dynamically across disparate AWS regions and Azure subscriptions.
  • Resistant Exponential Backoff: Intelligent retry wrappers ensure robust execution even during transient network or cloud API throttling events.
  • Modular Hygiene Classifiers: Encapsulates business logic for cost analysis (identifying oversized VMs and unattached disks) and security posture auditing (detecting unencrypted storage buckets and wide-open 0.0.0.0/0 security groups).

Business Impact & Automation

The platform replaces tedious manual DevOps auditing scripts with automated execution flows. Enterprises leveraging Cloud Auditor achieve instant visibility into infrastructure waste—reducing ongoing monthly cloud expenditures while hardening perimeter firewalls and identity compliance protocols in real time.
