Docker Container High Availability Big Data Framework

The patent uses Docker container technology to create virtual copies of database servers. Instead of duplicating physical hardware, the system creates containerized virtual instances that can be rapidly deployed and managed. The containerization approach allows multiple database server instances to run on shared physical infrastructure, reducing hardware requirements while maintaining availability through virtual duplication.

The patent introduces a container orchestration layer as an intermediary between physical hardware and database services. This intermediary manages resource allocation, container lifecycle, and failover mechanisms, enabling efficient utilization of underlying hardware resources while maintaining high availability through automated container management and recovery.

The patent segments the database server into independent containerized units using Docker technology. Each database instance runs in its own container with isolated file systems, processes, and dependencies. This segmentation allows individual containers to be managed, updated, and recovered independently without affecting the entire system, reducing operational complexity while maintaining availability.

The patent employs ephemeral container instances that can be rapidly created and destroyed. When failures occur or updates are needed, new container instances are spawned and activated quickly, while failed containers are discarded and recreated. This approach reduces complexity by avoiding long-term management of virtualized operating systems and enables simple restart-based recovery mechanisms.

The patent creates universal container templates that can serve multiple database instances and configurations. A single container image can be instantiated multiple times with different parameters to create dualized database servers. This multi-functionality approach reduces management complexity by using standardized, reusable container definitions rather than custom configurations for each instance.

The patent manages container dualization by changing parameters within standardized container templates rather than creating fundamentally different system configurations. Availability is achieved by modifying instance parameters (such as container IDs, network assignments, and data paths) of otherwise identical container templates, simplifying management through parameter-based differentiation rather than structural complexity.
