AWS Session Manager vs SSH

AWS Session Manager and SSH are two tools used for server access management, each with unique benefits and limitations. AWS Session Manager provides a way to access EC2 instances without opening inbound ports or managing SSH keys, and is integrated into the AWS ecosystem. It offers advantages such as no need for open ports, integrated IAM, logging, and no SSH keys, but has disadvantages like AWS dependency, learning curve, and connectivity requirements. SSH, on the other hand, is a mature tool that provides a secure way to access remote machines, with advantages like wide usage, direct control, offline access, and customizability. However, SSH has disadvantages like port exposure, key management, and logging and monitoring complexities. In terms of security, AWS Session Manager has advantages like no inbound ports, IAM integration, and session logging, while SSH requires effective key management and additional security measures. The author prefers SSH over AWS Session Manager due to its flexibility, portability, and integration with third-party tools. The choice between the two tools ultimately depends on specific setup, security requirements, and personal preferences. Both tools have their pros and cons, and understanding these can help decide which is best for individual needs.
