LinuxCon + CloudOpen + ELC-E Europe 2014

OpenStack, the fastest growing infrastructure-as-a-service (IaaS) platform in the open source community, has recently added a database-as-a-service (DBaaS) component named Trove, which saw its first production OpenStack release in April. Trove’s purpose is to provide scalable and reliable cloud DBaaS provisioning functionality for both relational and non-relational database engines.

In this presentation, we examine the motivation behind DBaaS, cover the architecture of Trove, and demonstrate the deployment of OpenStack Trove on an OpenStack private cloud, in order to provide MySQL DBaaS to OpenStack users. It is useful both for private cloud operators intending to deploy DBaaS, and to MySQL DBAs learning to interact with MySQL in an OpenStack DBaaS environment.

Coccinelle is a program matching and transformation tool for C programs that has been extensively applied to the Linux kernel and is used on a number of other C code bases. Coccinelle makes it easy to specify software specific rules for finding bugs and for updating software to use new APIs. These rules can then be applied automatically across an entire code base. Over 40 Coccinelle rules are already available in the Linux kernel source code. The goal of this tutorial is to enable developers to write their own. The tutorial is designed to be hands on. Participants should have Coccinelle (available via most Linux distributions) and the Linux 3.2 source code installed on their machines.

ktest.pl is a perl script that lives in the tools directory of the Linux kernel. Although it has "test" in its name, ktest.pl does not suppy any test itself but is a utility to automatically build, install, boot and then run a test on a test machine. The test machine must be a different machine than what ktest.pl is executed on. That other machine can be a virtual machine, and embedded device, or another desktop or server. The requirements is that the host box must be able to remotely reboot the test box, it must be able to read the test box console, and must be able to ssh into the test box.

This tutorial will walk the audience through, step by step, how to set up an embedded board and test it from a laptop computer using ktest.pl. It will include a live demonstration as well.

Configuration management and orchestration with Saltstack (Anirban Saha) - The true power of any infrastructure is unleashed only when there is complete command and control over the scale, speed, flexibility and operability of all its components. In this tutorial, Anirban Saha will demonstrate how Saltstack can achieve the same objectives, the basic architecture of Saltstack, its advantages over other alternatives and a hands-on walkthrough of Saltstack with the server and client components, which includes configuration of a small application stack, using the key features that Salt offers. Other highlights includes demonstration of additional features such as the built-in remote execution and overview of salt-cloud for cloud provisioning.

OpenNebula is a fully open-source cloud management platform that combines a simple, but flexible and powerful, virtualization manager that supports traditional IT features such as fault tolerance and failover, with the dynamic provisioning, elasticity and multi-tenancy of the enterprise cloud. The aim of this tutorial is to learn how it works and how to install it from scratch on CentOS as the operating system. The experience of building a real production ready and scalable Cloud is much more than just installing a Cloud Platform, that is why, thanks to OpenNebula's simplicity, we will discuss how to further integrate it with many Open Source technologies, like Ceph for the Virtual Machine storage or Ansible to bootstrap it all.

Attendees will build the cloud in two CentOS virtual machines in their own laptops using VirtualBox. Remember to come to the tutorial with VirtualBox installed and with the virtualization extensions enabled!
