The cloud is the new IT paradigm and has moved beyond being probable to being inevitable. No one can ignore it. Organizations have embraced cloud for various reasons such as agility, scalability, capex reduction, and a faster time to market their products and services. The cloud operating system, or cloud control layer or cloud software system or simply put cloud orchestrator, is at the heart of building a cloud delivering IaaS. While there are many choices available as far as the cloud orchestrator goes, OpenStack is a popular choice in the open source segment.
OpenStack is rapidly gaining momentum and is poised to become the leader in this segment. Therefore, it becomes imperative for organizations and IT managers / support teams to have these critical OpenStack skills. The challenge, however, stems from the fact that OpenStack is not a single product, but is a collection of multiple open source projects. Therefore, the challenge really is to have an understanding of these projects independently along with their interactions with the other projects and how they all are orchestrated together. While there is documentation available from the OpenStack project, it is important to have the necessary knowledge to stitch all of these services/components together and build your own cloud
This course is specifically designed to quickly help you get up to speed with OpenStack and give you the confidence and understanding to roll it out into your own data centers. From test installations of OpenStack running under VirtualBox to automated installation recipes that help you scale out production environments, this course covers a wide range of topics that help you install and configure a private cloud. The skills you will learn in this course will help you position yourself as an effective OpenStack troubleshooter.
This course is an attempt to provide all the information that is just about sufficient to kick start your learning of OpenStack and build your own cloud. We hope you will enjoy reading this course and more importantly find it useful in your journey towards learning and mastering OpenStack.
Module 1, Learning OpenStack, It is imperative for all the aspiring cloud administrators to possess OpenStack skills if they want to succeed in the cloud-led IT infrastructure space. This module comprises of installation prerequisites and basic troubleshooting instructions to help you build an error-free OpenStack cloud easily.
Module 2, OpenStack Cloud Computing Cookbook, in this module will show you exactly how to install the components that are required to make up a private cloud environment. Further you will learn to install and configure the components that are required to make up a private cloud environment.
Module 3, Troubleshooting OpenStack, in this module we'll walk through each OpenStack service and see how you can quickly diagnose, troubleshoot, and correct problems in your OpenStack. It will also provide high value information so that you can solve issues in storage, networking and compute.
