Ansible

Ansible is the leading agentless automation platform trusted by enterprises like NASA, BMW, and Hootsuite to automate infrastructure at scale. It uses simple YAML syntax that anyone can read, making complex automation accessible to both developers and system administrators.

What makes Ansible powerful is its agentless architecture - no software to install on managed systems, just SSH connectivity. This simplicity, combined with idempotent operations, makes it safe to run automation repeatedly without fear of breaking existing systems.

DevOps teams choose Ansible because it reduces complexity while increasing reliability. Large enterprises use it for configuration management across thousands of servers, while development teams leverage it for consistent application deployments and infrastructure provisioning.

Key Features

• Agentless Architecture - No software to install on managed systems, just SSH connectivity for immediate deployment • Human-Readable YAML Playbooks - Simple automation scripts that anyone can read, write, and maintain • Standard SSH Communication - Uses existing SSH infrastructure without additional network ports or protocols • Idempotent Operations - Safe to run repeatedly without breaking existing configurations or causing side effects • Extensive Module Library - Over 5,000 built-in modules covering cloud providers, databases, networking, and system management • Flexible Inventory Management - Static and dynamic host inventories with cloud provider integration and custom grouping • Ansible Vault Encryption - Secure storage and management of passwords, keys, and sensitive data within playbooks • Massive Parallel Execution - Run tasks across thousands of hosts simultaneously with configurable concurrency controls
