Overview of this book

OpenStack Open Source software is one of the most used cloud infrastructures to support software development and big data analysis. It is developed by a thriving community of individual developers from around the globe and backed by most of the leading players in the cloud space today. It is simple to implement, massively scalable, and can store a large pool of data and networking resources. OpenStack has a strong ecosystem that helps you provision your cloud storage needs. Add OpenStack's enterprise features to reduce the cost of your business. This book will show you the steps to build up a private cloud environment. At the beginning, you'll discover the uses of cloud services such as the identity service, image service, and compute service. You'll dive into Neutron, the OpenStack Networking service, and get your hands dirty with configuring ML2, networks, routers, and Distributed Virtual Routers. You’ll then gather more expert knowledge on OpenStack cloud computing by managing your cloud's security and migration. After that, we delve in to OpenStack Object storage and how to manage servers and work with objects, cluster, and storage functionalities. Also, as you go deeper into the realm of OpenStack, you'll learn practical examples of Block storage, LBaaS, and FWaaS: installation and configuration covered ground up. Finally, you will learn OpenStack dashboard, Ansible and Foreman, Keystone, and other interesting topics.

Managing security groups


Security groups are firewalls for your instances, and they’re mandatory in our cloud environment. The firewall actually exists on our OpenStack Compute host that is running the instance, and not as iptables rules within the running instance itself. They allow us to protect our hosts by restricting or allowing access to specified service ports, and also protect our instances from other users’ instances running on the same hosts. Security groups are the only way to separate a tenant’s instances from another user’s instances in another tenant when VLAN or tunnel separation isn’t available, or in instances where the flat networking model is in use.
