AWS Best Practices: Implementing Enterprise Governance
Comprehensive guide to establishing governance policies, IAM strategies, and compliance frameworks on AWS.
Enterprise governance on AWS requires a multi-layered approach combining IAM policies, organizational structure, and compliance automation. This guide covers the best practices we recommend for large-scale AWS deployments.
IAM Strategy & Access Control
AWS Identity and Access Management (IAM) is the foundation of enterprise governance. We recommend implementing a role-based access control (RBAC) model with clear separation of duties. Use AWS Organizations to manage multiple accounts, with each business unit or environment in its own account. Implement SCPs (Service Control Policies) to enforce guardrails at the organization level, preventing risky actions regardless of IAM permissions.
Resource Tagging & Cost Allocation
Consistent tagging is essential for governance, cost allocation, and resource management. Define a tagging strategy that includes cost center, environment, application, and owner tags. Enforce tagging through SCPs and AWS Config rules. Use tags to enable accurate cost allocation across business units and to automate resource lifecycle management.
Compliance & Audit Logging
AWS CloudTrail provides comprehensive audit logging of all API calls. Enable CloudTrail across all accounts and regions, storing logs in a centralized S3 bucket with MFA delete protection. Use AWS Config to track configuration changes and compliance status. Implement AWS Security Hub for centralized security findings and compliance monitoring.
Automated Compliance Checking
AWS Config Rules enable automated compliance checking against your governance policies. Create custom rules for organization-specific requirements, such as requiring encryption on all S3 buckets or enforcing VPC Flow Logs. Remediation actions can automatically fix non-compliant resources, reducing manual intervention.
Disaster Recovery & Business Continuity
Define RTO (Recovery Time Objective) and RPO (Recovery Point Objective) for each application. Use AWS Backup for centralized backup management across services. Implement cross-region replication for critical data. Test disaster recovery procedures quarterly to ensure they work when needed.
