Whenever we talk about IaaS (Infrastructure as a Service) or cloud management platform or cloud provisioners, we often think about VMWare vSphere, AWS EC2, Openstack, and co. Not known to many people, there is another project on the rise and this is OpenNebula. So what is OpenNebula? As quoted from the OpenNebula website:

One of my favorite conferences in 2014 was the first edition of Config Management Camp, back in February. A very rare occasion where we had major contributors and users from each of the current FOSS Configuration Management tools in a single building.  

Two months back OlinData announced OpsTheatre, a pluggable operations dashboard that runs on Node.js. Our in-house dev team believes this tool will be key in eliminating a growing issue in the DevOps community - the duplication of Operations Management tools. On top of that, we open sourced the project as we believe community support and involvement will be integral in the realization, manifestation and shaping of this vision.

It has been a while since the PuppetConf 2014 ended in San Francisco and there are lot of news that came out of it as usual. But, the biggest news is during the keynote that Luke Kanies, CEO of PuppetLabs announced there will be a new Puppet Server. A new Puppet Server? Yup. A Puppet Server and its not the same as our current Puppet Master. Curious on what this means I decided to check out the preview. All my opinions stated below are my own and does not reflect any of OlinData or PuppetLabs.

Puppet includes a basic puppet master web server based on Ruby’s WEBrick library. This default server cannot be used for real-life loads, as it can’t handle concurrent connections; it is only suitable for small tests with ten nodes or fewer. You must configure a production quality web server before you start managing your nodes with Puppet i.e. more robust – namely Apache and Passenger.

Having just come back from PuppetConf 2014 in the San Francisco last week, there have been a lot of new developments. Some of the most significant changes since Puppet was started all the way 10 years back have been announced.

OpsTheatre is a fully open source pluggable operations dashboard. It's ultimate goal is to host multiple other dashboards tightly integrated into OpsTheatre so you can manage your whole infrastructure from one location. OpsTheatre is a modular app with a backend built in node.js. It's frontend is currently an angular.js app which talks to the backend through REST API's. Both the frontend and the backend support plugins or modules.

pt-query-digest is a tool available from Percona for analysis of MySQL queries from slow log, general log and binary log files. It can also analyze queries from mysql processlist and tcpdump mysql data. It is one of the best tools for slow query analysis on mysql server and can help you to improve mysql performance and efficiency.

pt-stalk tool collects MySQL diagnostic data for further analysis to resolve intermittent issues.
