Learn how to implement continuous upstream deployment strategies for OpenStack cloud systems to eliminate disruptive "big bang" upgrades in this sponsored conference session. Discover LY Corp's approach to applying Continuous Upstream Deployment Policy to their OpenStack-based private cloud, which enabled successful brownfield upgrades across four major release cycles instead of requiring costly greenfield deployments. Explore the fundamental challenges of OpenStack upgrades, including the complexity of managing identity, compute, networking, and storage components simultaneously, and understand why traditional upgrade approaches create significant operational burden for both administrators and users. Examine the detailed upstream deployment policy framework and the mindset changes required for implementation, including modifications to internal code management practices and feature design philosophies. Gain insights into specific pain points encountered during brownfield upgrade processes and practical tricks for overcoming common obstacles. Review comprehensive lessons learned from two years of continuous upgrade operations, providing actionable strategies for maintaining operational continuity while keeping pace with upstream OpenStack development.
