Viri is a system for automatic distribution and execution of Python code on remote machines. This is especially useful when dealing with a large group of hosts.
With Viri, Sysadmins can write their own scripts, and easily distribute and execute them on any number of remote machines. Depending on the number of computers to administrate, Viri can save thousands of hours, that Sysadmins would spend transferring files, logging into remote hosts, and waiting for the scripts to finish. Viri automates the whole process.
Viri can also be useful for remotely managing host settings. It should work together with an application where the information about hosts would be maintained. This information can include cron tasks, firewall rules, backup settings,... After a simple Integration of this application with your Viri infrastructure, you can change any settings in the application, and see how it gets applied on the target host automatically.
The talk will cover next topics:
* Introduction to Viri
* Live demo on how to install Viri, write a Viri task, and execute it in a remote host
* Security concerns using Viri

How can Python help you deploy web applications to the cloud? Amazon EC2 provides virtual machines on demand but as a developer you still have to configure these machines and push your code to them. Fabric is a Python library that lets you execute commands on a remote machine, and Boto is a Python library for interfacing with Amazon web services. By using Fabric and Boto, you can easily create repeatable deployments and provision new resources as needed with minimal effort.
This talk will introduce Amazon Web Services and how to launch new machines using simple Boto scripts, and how to get started making your own repeatable deployments using Fabric scripts.
