Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Migrating workloads between single node and multi-node environments is challenging due to potential downtime, data loss, and the complexity of configuring different environments, which can result in high costs and resource burdens, including human administration, and risks of incorrect machine configuration.
Innovation Solution
A method and system for migrating workloads between single node and multi-node environments over a Transport Layer Security (TLS) network, which generates and stores files containing workload information, connects to a container cluster, and uses access information to establish a secure connection, thereby avoiding manual configuration and downtime, and ensuring compatibility with the target environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration methods are used for workload migration, then flexibility in configuration is improved, but time consumption and error risk increase
Solution Approach 1:
The patent uses file-based copying of workload configurations and cluster information between environments. The first machine generates a first file containing workload information, and the second machine reads a second file from the container cluster, enabling automated replication of configuration data without manual intervention while maintaining adaptability through environment-specific file formats
Solution Approach 2:
The patent introduces access information stored in files as an intermediary mechanism to connect the first machine to the container cluster. This intermediary file-based communication layer enables secure workload migration over TLS networks while automating the configuration transfer process, reducing both time and manual configuration requirements
2Productivity
If automated migration methods are used, then migration speed is improved, but complexity of the migration system increases
Solution Approach 1:
The patent segments the migration process into distinct independent steps: generating workload information files on the first machine, reading cluster configuration files from the container cluster, establishing secure connections over TLS networks, and transferring workloads. This segmentation simplifies the overall system by breaking down the complex migration task into manageable, independently implementable modules
Solution Approach 2:
The system performs self-service migration by automatically generating required files, reading configuration information, establishing connections using stored access information, and executing workload transfers without requiring external manual intervention. This automation improves migration speed while the use of standard file formats and protocols keeps the system complexity manageable
3Reliability
If secure connection protocols like TLS are implemented, then security is improved, but network configuration complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-storing access information including TLS certificates and connection parameters in files on the first machine before migration. This advance preparation eliminates the need for complex real-time TLS configuration during migration, as the secure connection parameters are already available in the workload information files and second file
Solution Approach 2:
The patent copies secure connection credentials and configuration files between environments using the same file-based mechanism used for workload data. The first machine generates and stores access information files, which are then read and used to establish secure connections to the container cluster, maintaining security while simplifying the migration process
4Quantity of substance
If single node environment is used, then resource requirements are reduced, but scalability is limited
Solution Approach 1:
The patent creates a universal migration system that can operate between different environment types (single node and multi-node) using the same file-based approach. The first machine can generate workload files that are compatible with both environment types, and the container cluster can read these files regardless of the source environment, enabling the system to adapt to different computational resource requirements while maintaining a consistent migration methodology
