Implementing Automated Budget Management for Multi-Account AWS Environments: Centralized Control and Real-Time Notifications

This article discusses an automated solution for managing AWS spending across multiple accounts. The solution uses a central management account to configure unique budget thresholds for each account, track spending in real-time, and send email notifications when accounts approach or exceed their allocated budgets. The architecture is event-driven and uses AWS DynamoDB, Lambda, Systems Manager, and Budgets to automate budget management and provide timely alerts.
