Managing EC2 instances at scale requires ensuring that all instances are properly configured and connected to AWS Systems Manager (SSM). Issues like missing or non-responsive SSM Agents and unmanaged instances can create operational gaps and disrupt automation. To solve this, we can use AWS Config, Amazon EventBridge, and AWS Lambda to build a monitoring and alerting system that continuously checks compliance, detects SSM Agent health issues in real time, and triggers alerts or remediation – improving visibility, security, and control across your AWS environment. A. Checking EC2 Instances for SSM …

AWS VPC Design Patterns for Building Low-Latency, High-Performance Architectures
When building modern applications in the cloud, performance depends on more than powerful compute instances or scalable databases.
