From Big Bangs to Crockpots: Strategies for Changing Production with No Downtime

Explore strategies for changing production environments without downtime in this 59-minute conference talk by Ryan Bergman from ChariotSolutions. Learn from real-world examples at John Deere, including moving a high-volume transactional monolith to AWS with minimal downtime, rewriting permission storage systems, and balancing storage vs. performance for a massive agronomic data pond. Discover techniques for cloud migration, breaking up monoliths, and implementing gradual changes through "crockpot migrations." Gain insights into handling growing data needs, API gateways, database migrations, and balancing machine learning requirements in large-scale systems. Understand the challenges and solutions involved in modernizing legacy systems and optimizing performance in cloud environments.
