Ansible vs StackStorm: What are the differences?
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; StackStorm: Open Source IFTTT for Ops: event-driven automation, security responses, auto-remediation with workflow engine & ChatOps. StackStorm is a platform for integration and automation across services and tools. It ties together your existing infrastructure and application environment so you can more easily automate that environment -- with a particular focus on taking actions in response to events.
Ansible can be classified as a tool in the "Server Configuration and Automation" category, while StackStorm is grouped under "Remote Server Task Execution".
Some of the features offered by Ansible are:
- Ansible's natural automation language allows sysadmins, developers, and IT managers to complete automation projects in hours, not weeks.
- Ansible uses SSH by default instead of requiring agents everywhere. Avoid extra open ports, improve security, eliminate "managing the management", and reclaim CPU cycles.
- Ansible automates app deployment, configuration management, workflow orchestration, and even cloud provisioning all from one system.
On the other hand, StackStorm provides the following key features:
- Automations tie events to actions you’d like to take, using a rules engine and, if you want, comprehensive workflow. Automations are your operational patterns summarized as code.
- StackStorm automations work either by starting with your existing scripts – just add simple meta data – or by authoring the automations within StackStorm.
- Automations are the heart of StackStorm – they allow you to share operational patterns, boost productivity, and automate away the routine.
"Agentless" is the primary reason why developers consider Ansible over the competitors, whereas "Auto-remediation" was stated as the key factor in picking StackStorm.
Ansible and StackStorm are both open source tools. It seems that Ansible with 38.2K GitHub stars and 16K forks on GitHub has more adoption than StackStorm with 3.32K GitHub stars and 439 GitHub forks.
