DevOps Tools in Python

The major clouds publish official Python SDKs: boto3 for AWS (the AWS CLI is itself a Python program), and the Azure and Google Cloud libraries, which are split into one package per service. Chalice builds serverless apps on AWS Lambda with a Flask-like decorator API. Fabric runs shell commands on remote hosts over SSH from Python code, which suits simple deployment scripts.

For configuration management, Ansible is agentless: it connects over SSH and applies YAML playbooks. Salt traditionally runs agents on managed hosts and reacts to events, which scales to large fleets. pyinfra writes deployments in Python and turns them into shell commands run over SSH, and cloud-init configures cloud instances on first boot. On the process side, psutil reads CPU, memory, disk and process information across platforms, Supervisor keeps long-running processes alive, sh calls programs as if they were functions, Sentry SDK reports errors, Flower monitors Celery workers, and BorgBackup makes deduplicated, encrypted backups.
