Hybrid Cloud Storage Segmentation for Cost and Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cloud storage solutions face challenges in balancing accessibility, cost, and performance, with public cloud storage offering ease of use but high costs for data retention and access, while private cloud storage requires upfront costs and maintenance expenses.
Innovation Solution
A hybrid cloud storage arrangement that combines a private data center with a public cloud service, where data objects are stored locally in the private data center, and metadata and policies are managed in the public cloud, allowing for scalable and cost-effective data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is stored in public cloud storage service, then accessibility and ease of use are improved, but cost for data retention and access increases
Solution Approach 1:
The system segments cloud storage functionality into two parts: metadata management (directory information, policies) is stored in the public cloud for accessibility, while actual data objects are stored locally in private storage for cost efficiency. This segmentation allows the system to enjoy the ease of access provided by public cloud without bearing the full cost of public cloud data retention.
Solution Approach 2:
A hybrid cloud storage system acts as an intermediary between private storage and public cloud services. It maintains local data storage while using public cloud only for metadata management, thereby mediating between the accessibility benefits of public cloud and the cost benefits of private storage.
2Quantity of substance
If data is stored in private cloud storage, then cost and performance are improved, but scalability and ease of use deteriorate
Solution Approach 1:
The hybrid cloud storage system provides multi-functionality by combining private storage capabilities with public cloud metadata management. This allows the system to maintain cost and performance benefits of private storage while gaining the scalability and ease of use benefits of public cloud services through standardized interfaces.
Solution Approach 2:
The system adds a new dimension to private storage by integrating public cloud metadata management capabilities. This dimensional addition enables private storage to achieve scalability and ease of use without sacrificing cost efficiency or performance.
3Ease of operation
If metadata and directory information are stored in public cloud, then access flexibility is improved, but system complexity increases
Solution Approach 1:
The system extracts metadata and directory information management from the main storage system and places it in the public cloud. This extraction simplifies the local storage system while maintaining access flexibility, as the public cloud handles metadata operations independently.
Data Source
AI summary
A cloud environment is provided generally having at least one private data center possessing a controller/routing system and nonvolatile mass storage, a plurality of data objects retained in the nonvolatile mass storage, and a public cloud storage service provider linked to the controller/routing system. The public cloud storage service provider possessing a database containing policy decisions and metadata of the plurality of data objects. The private data center is not in possession of the policy decisions and the metadata for the plurality of data objects, rather the public cloud storage service provider is. The private data center in possession of the plurality of data objects, whereas the public cloud storage provider is not. The public cloud storage service provider adapted to be communicatively linked to an end-user computing system by way of the controller/routing system. The data center is independent of the public cloud storage provider.
