Ansible have great integration with multiple operating systems (even Windows) and some hardware (switches, Firewalls, etc). It has multiple tools that integrate with the could providers. Almost every worth-notice cloud provider is present in the ecosystem (AWS, Azure, Google, DigitalOcean, OVH, etc...) +But ansible is way more! It provides an execution plans, an API, library, callbacks, not forget to mention - COMMUNITY! and great support by developers! -## Main cons and pros -### Cons +### Main cons and pros + +#### Cons It is an agent-less tool - every agent consumes up to 16MB ram - in some environments, it may be noticable amount. It is agent-less - you have to verify your environment consistency 'on-demand' - there is no built-in mechanism that would warn you about some change automatically (this can be achieved with reasonable effort) Official GUI Tool (web inferface) - Ansible Tower - is great, but it is expensive. There is no 'small enterprice' payment plan. Easy workaround with Rundeck or Jenkins is possible with reasonable workload. -### Pros +#### Pros It is an agent-less tools In most scenarios, it use ssh as a transport layer. In some way you can use it as 'bash on steroids'. -It is very-very-very easy to start. If you are familiar with ssh concept - you already know ansible (ALMOST). My personal record is: 'I did show how to install and use ansible (for simple raspberry pi cluster management) and it tool me 30 seconds to deliver a working tool !!!)' +It is very-very-very easy to start.

I do provide a training services - I'm able to teach a production-ready person - in 8 hours (1 training day)! It covers all needed to work aspects! No other tool can match this ease of use! -It executes when you do it - other tools (salt, puppet, chef - might execute in different scenario than you would expect) +It executes 'as is' - other tools (salt, puppet, chef - might execute in different scenario than you would expect) Documentation is at the world-class standard! The comunity (github, stackOverflow) would help you very fast. Writing own modules and extension is fairly easy. - -### Neutral +#### Neutral Migration Ansible<->Salt is failrly easy - so if you would need an event-driven agent environment - it would be a good choice to start quick with Ansible, and convert to salt when needed. -## Basics on ansible +#### Some concepts Ansible uses ssh or paramiko as a transport layer. In a way you can imagine that you are using a ssh with API to perform your action. -In the 'low-level' way you can use it to execute remote command in more controlled way (still using ssh). -On the other hand - in advanced scope - you can use python anible code as a library to your own python scrips! This is awesome! (if you know what you are doing). It is a bit like fabric then. +The simplest way is to execute remote command in more controlled way (still using ssh). +On the other hand - in advanced scope - you can wrap Ansible (use python Ansible code as a library) with your own Python scrips!
