Ansible vs Otto: What are the differences?
What is Ansible? Radically simple configuration-management, application deployment, task-execution, and multi-node orchestration engine. Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates. Ansible’s goals are foremost those of simplicity and maximum ease of use.
What is Otto? Development and Deployment Made Easy. The successor to Vagrant. Otto automatically builds development environments without any configuration; it can detect your project type and has built-in knowledge of industry-standard tools to setup a development environment that is ready to go. When you're ready to deploy, otto builds and manages an infrastructure, sets up servers, builds, and deploys the application.
Ansible belongs to "Server Configuration and Automation" category of the tech stack, while Otto can be primarily classified under "Virtual Machine Management".
"Agentless" is the primary reason why developers consider Ansible over the competitors, whereas "Vagrant-like" was stated as the key factor in picking Otto.
Ansible and Otto are both open source tools. It seems that Ansible with 38.2K GitHub stars and 16K forks on GitHub has more adoption than Otto with 4.41K GitHub stars and 252 GitHub forks.
