Audience: Beginner About: OpenStack is notoriously complex to deploy and update. Traditional method of using RPMs is extremely unreliable due to inter-dependencies resulting into delays in deployment and failures in update. Any change in any of the RPMs may can adversely impact other RPMs and the deployment risks failures and delays. Leveraging OpenStack upstream Kolla project, Oracle has transformed the deployment. OpenStack services are deployed as micro-services in docker containers which are fully independent from each other. Using the Ansible deployment tool, any of the containers can be changed or replaced easily without impacting other containers. In this session, you will learn the details of the ACTUAL EXPERIENCE with Oracle OpenStack distribution using Docker containers Actual time for the fast deployment: small, medium and large OpenStack deployments Learn the surprisingly easy update process and actual time required. Understand the recommended OpenStack configuration for different size of deployments Learn the actual performance, scalability and tuning for different deployment size Speaker Bio: Avi Miller – Product Management Director, Oracle Avi is an accomplished technical product manager with extensive experience across the operating system, virtualisation and application stacks.

Building a Cloud Infrastructure is Not for the Timid
Deployment Plane
(infrastructure deployment + configuration & reconfiguration of services)
Control Plane
(Interaction with services to build instances)
Data Plane
(Deployed instances delivering application content to tenants)
OpenStack involves
multiple planes, each
focused on specific
requirements, with varying
levels of complexity
Our goal is to minimize
complexity and simplify
deployments…..
…by using containers for
deployment of
OpenStack services

Previous deployment model
– RPM based - thousands of
interdependent packages
– Unstable. Difficult to Manage
• Conflicting interdependencies from different
versions of OS and services
• Change in one can bring down other
– As a result…..
• Long time to deploy
• Difficult to upgrade
• High risk and unforeseen downtime with
changes
Deployment with Docker Container
– Package each service as an independent
micro-service in a Docker container.
– Only thing that changes is the
configuration loaded into the container
• New containers are easy to create and fast
and reliable to deploy
• Does not reconfigure anything else
• Provides immutability and portability
– As a result…..
• Simplified and fast deployment
• Easy to upgrade, operate and modify
• Reliable
Why Docker Containers for OpenStack Deployment?

• Oracle’s own Docker containers
based deployment merged with
OpenStack Kolla project
– Oracle contributing upstream
• Production ready all services
– Install from source (not RDO)
• Deployment tools: Ansible
playbooks
• Simplified rapid deployment,
upgrade and operation

Deployment RPM based deployment Docker Containers based

50 Compute nodes Approx 120 minutes 60 minutes or 50% faster
100 compute nodes Approx 180 minutes 90 minutes or 50% faster
Updating the services Several Manual Steps and

than the fresh deployment while
significantly faster and reliable
than RPM- based (measurements

Measurements with Rally Simulation
2 control nodes + 3 compute nodes. Using Nova command and Rally
• 1,434 accumulated VMs booted in 10 minutes with failure rate =0
• 200 concurrent VM (1 fail) booted by Nova command
Total duration (from API request to VM launch) from Rally:
1000 iterations in booting 1000 VM with 100 concurrency
– 97.7% success, Average: 119 seconds
Rally Tuning: Update “nova_server_boot_timeout = 600
– Failures: 0 (100% success), Average: 132 seconds
