Control with Ansible Tower, Part 2
This is the second in a series of posts about how Ansible and Ansible Tower enable you to manage your infrastructure simply, securely, and efficiently.
When we talk about Tower, we often talk in terms of Control, Knowledge, and Delegation. But what does that mean? In this series of blog posts, we'll describe some of the ways you can use Ansible and Ansible Tower to manage your infrastructure.
In our first blog post, we described how Ansible Tower makes it easy to control the way your infrastructure is configured via configuration definition and continuous remediation.
But controlling the configuration of your infrastructure is just one step. You also need control of the components of your infrastructure - your inventory. You need to do day-to-day management tasks on demand. And Ansible Tower makes those easy as well.
INVENTORY - THE BASICS
If you’ve used Ansible, you know about the basics of inventory. A static Ansible inventory is just an INI-style file that describes your hosts and groups, and optionally some variables that apply to your hosts and groups. Here's an example from the Ansible documentation.
{% raw %}[atlanta] host1 host2 [raleigh] host2 host3 [southeast:children] atlanta raleigh [southeast:vars] nameserver=dns.southeast.example. Continue reading

Empty DDoS Threats: Meet the Armada Collective
Beginning in March 2016, we began hearing reports of a gang of cybercriminals once again calling themselves the Armada Collective. The calling card of the gang was an extortion email sent to a wide variety of online businesses threatening to launch DDoS attacks if they weren't paid in Bitcoin.
From The Wizard of Oz (1939)
We heard from more than 100 existing and prospective CloudFlare customers who had received the Armada Collective's emailed threats. We've also compared notes with other DDoS mitigation vendors with customers that had received similar threats.
Our conclusion was a bit of a surprise: we've been unable to find a single incident where the current incarnation of the Armada Collective has actually launched a DDoS attack. In fact, because the extortion emails reuse Bitcoin addresses, there's no way the Armada Collective can tell who has paid and who has not. In spite of that, the cybercrooks have collected hundreds of thousands of dollars in extortion payments.
The Threat
The extortion emails sent by the Armada Collective have been remarkably consistent over the last two months. Here's an example:
