Course CLD105
Cloud Computing Using Openstack and Linux - Deployment and Administration
Cloud Computing Using Openstack and Linux - Deployment and Administration
Duration: 3 Days
Course Synopsis
Openstack was developed as a joint effort by Rackspace and NASA. Ubuntu will be moving its cloud computing offering to Openstack in the next Ubuntu release. Openstack is an attractive proposition for the implementation of both private and public clouds. Being open source it is not locked in to proprietary solutions. Also, widespread adoption of openstack by data centre providers should help reduce the cost of cloud computing. As well as the installation and administration module described here there will be an application development module [Please inquire]
Deploying and Administering Openstack on Linux systems is a 3 to 5 day module (depending on level of experience) aimed at system administrators and help desk/support staff.
Attendees are expected to have basic programming skills and a basic understanding of cloud computing concepts as well as some experience of configuring and administering Linux systems. For fairly experienced Linux sysadmins the course can be covered in 3 days. For those with less experience 5 days will be required to cover the necessary Linux tools and utilities and shell programming topics.
