Editor's Notes
- #5 Complexity and perceived immaturity are the two primary barriers to OpenStack adoption. Complexity: The infinite number of configurations and subsequent lack of operational experience and OpenStack expertise hinder adoption. Perceived Immaturity: While it has matured over the last 5 years and 12 releases, there is still some residual perception that OpenStack isn’t reliable or ready for production workloads.
- #10 Openstack networking started with nova-network: a very basic way of using VLANs to interconnect VMs. Very limited.
- #14 #1: from initial contract through monthly billing and updates
- #15 HA, hardening, scale
- #18 Insert information about the foundation we laid with Version 9 --- designed for production-grade in the enterprise, with scalability, availability and automation in mind. Moved to a container-based architecture. Using Linux containers (LXC) to deploy the OpenStack services which isolates the services and improves cross-service interconnectivity. This allows customers to independently scale each service and enables us to provide seamless, in-place upgrades from one release to another. Moved to a 3-node MariaDB Galera cluster with quorum. This allows for better handling of single-node failures and recovery of a lost node. In the previous architecture we encountered a number of split-brained scenarios with both nodes thinking they were master. Moved RabbitMQ to a 3-node cluster with quorum. Provides the same improvement to fault tolerance. Allows us to utilize OpenStack’s ability to connect to multiple Rabbit nodes along with HA queues – again, providing a more fault tolerant and scalable environment as these clusters can be easily scaled where as we were stuck with the pair in previous architectures. Replaced Chef with Ansible for automated cloud deployment and configuration management. With the move to containers, the Chef Package/Service model was much heavier than we needed. Ansible provides us an automation framework great at orchestrating tasks across multiple hosts (sequentially or in parallel). We use Ansible to lay down containers and manage the installation of source code. Added robust audit logs for compliance reporting – added a controller node for Logstash, ElasticSearch and Kibana – this is our logging server which centralizes logging services to help provide customers and our support team with event services data Added Heat orchestration – enables customers to automatically provision infrastructure, services and applications Insert additional enhancements from Version 10
