A Little Bit Background …• Bluemix Private Cloud is

IBM’s private cloud as service based on OpenStack

• Bluemix Private Cloud landed in China to support IBM’s Cloud business there.

• We were building an OpenStack Operations Team from scratch

Agenda• Define an OpenStack Operations Team

• Operating Model• Processes• Tooling• Teaming

• Tooling Integration• Cliché: OpenStack upgrade, HA, Live Migration

Operating OpenStack is like …

Tooling Integration• A lot of screens to watch• A lot of systems to work on• A lot of interruptions• Use your tools to “kill” them

Tooling IntegrationAs a good start: Kill ”context switch” – work on a single platform

Tooling IntegrationAs a good start: Kill ”context switch” – work on a single platform

Tooling IntegrationWhat’s next: Kill ”all interruptions” – workflow automation across platforms

Cliché – Where BOOOOOM Happens• Implementations & Operations: Change management• The Practices of Upgrade• The Story of HA• The Myth of Live Migration

Change management• “Infrastructure as Code”• Incoming change requests

• Customer initiated requirements• Internal enhancements roll out• Compliance

• Change planning for Consistency• Priorities• Dependencies

OpenStack Upgrade• Prerequisites: deployment automation

• Consistency – cloud configurations in CMDB• Idempotency – code to run OpenStack upgrade

• Upgrade process design• Upgrade orchestration• Repeatable success &

minimum disruption

Reference: Upgrading OpenStack: A Best Practices Guide

Let’s talk about High Availability….• Architecture decisions for HA

• Eliminate SPOF; Non-disruptive upgrade; Load Balancing; …• Inherent availability = MTTF / (MTTF + MTTR)

• HA’s “dark side” for cloud operations• Recovery with HA resetting• Complexity’s impact on recovery time

• Mitigation plan• Built-in monitoring for HA mechanism• Recovery automation

Live Migration? • Does ”nova live-migrate” work?• Manage customer expectations• Abuse prevention

• Limited appropriate scenarios• Automation with caution• Integration with pre & post-

verification routine
