Virtualized Overlay Network for Data Center Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data center management systems face challenges in efficiently restoring and migrating virtualized workloads across different physical locations while maintaining data integrity and security, particularly due to shared hardware resources and varying hardware profiles across customer locations.
Innovation Solution
The system employs a virtualized overlay network and virtualized volume identifiers to abstract physical network resources and storage volumes, enabling seamless transfer and configuration of workloads between data centers, with cloud management orchestrating the deployment and restoration of infrastructure as a service (IaaS) workloads, including compute, storage, and networking components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is transferred between data centers with different hardware profiles, then migration capability is improved, but hardware compatibility issues arise
Solution Approach 1:
The patent introduces a virtualization layer as an intermediary between the physical hardware and workloads. This virtualization layer abstracts hardware-specific details, allowing workloads to migrate between data centers with different hardware profiles without compatibility issues. The virtualized overlay network and virtualized volume identifiers act as mediators that decouple the workload from the underlying hardware architecture.
Solution Approach 2:
The patent segments the data center infrastructure into distinct virtualized components: virtualized compute resources, virtualized overlay network, and virtualized volume identifiers. This segmentation allows each component to be independently managed and migrated, improving adaptability while maintaining reliability through consistent virtualization interfaces across different hardware platforms.
2Productivity
If physical network resources and storage volumes are shared across multiple customers, then resource utilization is improved, but data security and isolation are compromised
Solution Approach 1:
The patent uses virtualized overlay networks as intermediaries to provide secure multi-tenant sharing of physical network resources. The overlay network creates isolated virtual networks that allow multiple customers to share physical infrastructure while maintaining data security and isolation. Similarly, virtualized volume identifiers act as intermediaries that enable secure sharing of storage resources.
Solution Approach 2:
The patent segments shared physical resources into isolated virtual resources through virtualization. Each customer receives dedicated virtual network resources and storage volumes that are logically separated but physically shared, improving resource utilization while maintaining security through virtualization-based isolation boundaries.
3Reliability
If virtualized workloads are migrated across data centers, then disaster recovery capability is improved, but maintaining data integrity during transfer becomes more difficult
Solution Approach 1:
The patent creates and maintains copies of virtualized workload data across multiple data centers. The virtualized overlay network and virtualized volume identifiers enable consistent copying of data while maintaining integrity through virtualization-based data structures that preserve data relationships during transfer and replication operations.

AI summary
A system can maintain a first data center that comprises a virtualized overlay network and virtualized volume identifiers. The system can determine to perform a restore of data of the first data center to a second data center, the data comprising first instances of virtualized workloads. The system can transfer the data to the second data center. The system can configure the second data center with the virtualized overlay network and the virtualized volume identifiers. The system can operate the virtualized workloads on the second data center, the second instances of the virtualized workloads invoking the second instance of the virtualized overlay network and the second instance of the virtualized volume identifiers.
