  • – This books should become a reference for how doing cool things in your daily business with Ansible, things you can not find in the official docs.
  • Ansible Cheat Sheet | – Ansible is the cool, new kid on the block that is IT automation. So, just in case you need an Ansible Cheat Sheet, we’ve got you covered
  • zorangagic/awsinfo – Daily Inventory of all AWS resources in excel format
  • High availability clustering on AWS | Zoran’s Blog – How do we keep legacy applications highly available on AWS? I have already written about this previously and there are many good alternatives with the upcoming Cloudwatch instance recovery the easiest to implement. Yet Cloudwatch instance recovery or autoscaling group with min=1,max=1 still requires failure to be detected (1-2 mins) and new instance to be booted up (2-3 mins). If the application can not tolerate outage of 3-5 minutes then high availability clustering may be a good alternative
  • jordansissel/pleaserun: An attempt to abstract this “init” script madness. – Pleaserun is a tool to generate startup scripts for the wasteland of sorrow that is process launchers.

  • One Thing Well | Let’s Encrypt – Let’s Encrypt is now in public beta and offers a command line tool that makes the process of getting and renewing certificates easy, but you have to run it as root, and it’s designed to rewrite your web server’s configuration files. Here’s a selection of alternative tools and clients:
  • Tsung – It can be used to stress HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP and Jabber/XMPP servers. Tsung is a free software released under the GPLv2 license. The purpose of Tsung is to simulate users in order to test the scalability and performance of IP based client/server applications. You can use it to do load and stress testing of your servers. Many protocols have been implemented and tested, and it can be easily extended. It can be distributed on several client machines and is able to simulate hundreds of thousands of virtual users concurrently (or even millions if you have enough hardware …). Tsung is developed in Erlang, an open-source language made by Ericsson for building robust fault-tolerant distributed applications. [ via ]
  • Internet Redundancy with ASA SLA and IPSec – PacketU – I’ve seen a lot of examples of redundant Internet connections that use SLA to track a primary connection. The logic is that the primary Internet connection is constantly being validated by pinging something on that ISP’s network and routing floats over to a secondary service provider in the event of a failure. I was recently challenged with how this interacted with IPSec. As a result I built out this configuration and performed some fairly extensive testing.

  • Hughes Systique Corp. > Research & Innovation > Newsletter > Issue 2 > mySQL – A typical MySQL cluster requires at least 4 nodes for deploying a High Available MySQL database cluster. The typical configuration of any enterprise application is a 2 Node solution (Active-Standby mode or Active-Active Mode). This is where the real challenge lies: in fitting the MySQL Cluster Nodes in the 2 Nodes offering the application services and then making it work in the configuration without a single point of failure.
  • Corosync / Pacemaker – Execute script on failover – – With Corosync/Pacemaker there is no easy way to simply run a script on failover. There are good reasons for this, but sometimes you want to do something simple. This tutorial describes how to change the Dummy OCF resource to execute a script on failover. In this example it is a script which triggers a few SNMP traps, sends an alert to Nagios and sends some data to Graphite. SNMP alone could be done with the ocf:heartbeat:ClusterMon resource, but the other stuff not.
  • Home – A Banana Pi powered website
  • UrBackup – Client/Server Open Source Network Backup for Windows and Linux – UrBackup is an easy to setup open source client/server backup system, that through a combination of image and file backups accomplishes both data safety and a fast restoration time. File and image backups are made while the system is running without interrupting current processes. UrBackup also continuously watches folders you want backed up in order to quickly find differences to previous backups. Because of that incremental file backups are really fast. Your files can be restored through the web interface or the Windows Explorer while the backups of drive volumes can be restored with a bootable CD or USB-Stick (bare metal restore). A web interface makes setting up your own backup server really easy.

  • Mail-in-a-Box – Mail-in-a-Box turns a fresh cloud computer into a working mail server. You get contact synchronization, spam filtering, and so on. On your phone, you can use apps like K-9 Mail and CardDAV-Sync free beta to sync your email and contacts between your phone and your box.
  • ClusterLabs/hawk – A web-based GUI for managing and monitoring the Pacemaker High-Availability cluster resource manager
  • Hawk – ClusterLabs – Hawk (HA Web Konsole) is a web-based GUI for managing and monitoring Pacemaker HA clusters. It is generally intended to be run on every node in the cluster, so that you can just point your web browser at any node to access it,
