In two previous posts, my colleagues Oleg Gelbukh and Piotr Siwczak covered most of the ground on making OpenStack highly available (HA). If you haven't read those posts yet, it's a good time to do so: Oleg's post on OpenStack HA in general Piotr's post on MySQL and RabbitMQ HA. In this post, I'll offer some direct practical advice on completing the puzzle: …

Introduction After the April Essex release, there's big change in planned for OpenStack's volume management; it is now called Cinder. Cinder is a new service for OpenStack, one that separates storage management logic. Until now, in the Essex release, this logic was a part of Nova, and was called the nova-volume component. But, as often happen in software, logical interdependencies between components within …

Oleg Gelbukh's last blog article gave us a bird's eye view of different aspects of high availability in OpenStack. Even though all OpenStack components are designed with high availability in mind, the software still relies on external software, such as the database and the messaging system. It is left up to the user to deploy them in a fail-proof manner. It …

Mirantis OpenStack ExpressDeveloper Edition:Get Private-Cloud-as-a-Service for a year free. Recently I outlined how VlanManager works and how it ensures network scalability and tenant isolation. Up to this point, however, I've only dealt with fixed IP networks of different tenants. While fixed IPs are what instances are given by default, they do not ensure that the instance is immediately reachable from the outside …

In a previous post I explained the basic mode of network operation for OpenStack, namely FlatManager and its extension, FlatDHCPManager. In this post, I'll talk about VlanManager. While flat managers are designed for simple, small scale deployments, VlanManager is a good choice for large scale internal clouds and public clouds. As its name implies, VlanManager relies on the use of …

Mirantis OpenStack ExpressDeveloper Edition:Get Private-Cloud-as-a-Service for a year free. In a previous post about OpenStack networking, my colleague Piotr Siwczak explained how FlatManager and FlatDHCPManager works in a multi-host network setup. Here, I will explain how FlatDHCPManager works with single-host networking. It is perhaps easier to understand; it also happens to be the default mode you get when installing OpenStack using one …
