Dragonfly offers three main strategies to achieve high availability for its deployments, catering to different infrastructure needs and preferences. Redis Sentinel provides a time-tested solution by monitoring and managing failovers for Dragonfly instances, using a distributed system to avoid single points of failure. Meanwhile, the Dragonfly Kubernetes Operator integrates with Kubernetes to manage high availability in a cloud-native manner, offering health checks and scaling capabilities, though it lacks the sophisticated replica selection of Sentinel. Lastly, Dragonfly Cloud presents a fully managed, autopiloted approach where high availability configurations, including failovers and replica management, are handled automatically across availability zones, ensuring seamless operations without manual intervention. Each option provides unique advantages, allowing users to choose based on their specific requirements for control, integration, and ease of use.
