Cloud IT Infrastructure Audit Checklist for AWS, Azure and GCP

Cloud infrastructure gives companies the flexibility to scale quickly, deploy services globally, and innovate faster. But as environments grow, they often become complex ecosystems of compute resources, containers, databases, networks, and integrations. Without regular review, this complexity can lead to security gaps, inefficient architecture, unnecessary cloud spending, and performance bottlenecks that are difficult to detect until they affect operations.

A Cloud IT Infrastructure Audit helps organizations evaluate the health of their cloud environment. Using a structured checklist, experts review architecture design, security configurations, access control policies, monitoring systems, backup strategies, and cost efficiency. The goal is to identify risks, eliminate wasted resources, and ensure the infrastructure is reliable, secure, and ready to scale as the business grows.

This checklist outlines key areas to assess during a Cloud IT Infrastructure Audit, ensuring your cloud environment remains secure and optimized.

Areas the checklist covers

• Architecture: account and network structure, availability zones and single points of failure.
• Security configuration: identity and access management, encryption, security groups and public exposure.
• Access control: least privilege, MFA, unused credentials and service accounts.
• Monitoring and logging: coverage, retention and alerting.
• Backup and recovery: backup policies, restore tests and recovery objectives.
• Cost efficiency: idle and oversized resources, commitments and tagging.
