Farewell to Bastion Hosts: Achieving Secure and Intelligent Operations for Private Subnets Using AWS EICE (EC2 Instance Connect Endpoint) and Chaterm | Amazon Web Services

English version | 中文版本

Summary: This article introduces the integration of Chaterm, an AI-powered terminal tool, with AWS EC2 Instance Connect Endpoint(EICE) to address operational challenges in private subnets. Traditional approaches require VPNs or bastion hosts,whereas EICE leverages IAM-based authentication to establish secure connections without public IP addresses. Chaterm wraps the EICE capability with cross-platform auto-adaptation and a visual interface. More importantly, its built-in AI Agent can perform intelligent health checks, fault diagnosis, and batch management directly on private EC2 instances —significantly improving both operational efficiency and security.
