Centralized Tenancy Session Tracking Across Multi-Region Clouds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-region cloud environments, managing tenancy sessions across distributed data centers is inefficient and prone to errors due to the lack of centralized storage and management of session information, leading to potential security risks and resource wastage.
Innovation Solution
A global region data center is designated to centrally store and manage session information for network access programs, ensuring only one active session per tenancy and facilitating seamless session creation and cleanup, thereby reducing resource allocation and improving session management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distributed data centers manage tenancy sessions independently, then system scalability and regional autonomy are improved, but session management reliability and consistency deteriorate
Solution Approach 1:
The patent introduces a centralized session management service that aggregates session information from multiple distributed data centers into a unified view. This service maintains a global registry of active sessions across all regions, enabling consistent session management decisions regardless of where users are located. The centralized service coordinates session creation, activation, and termination across distributed tenancies, resolving the contradiction by combining local independence with global coordination.
Solution Approach 2:
The centralized session management service acts as an intermediary between distributed data centers and users. It receives session status information from regional data centers, processes it centrally, and returns coordinated responses. This intermediary layer ensures that session management decisions are made consistently across all regions while maintaining the scalability of the distributed architecture.
2Reliability
If centralized session information storage is implemented, then session management reliability is improved, but device complexity increases
Solution Approach 1:
The centralized session management service is designed as a multi-functional platform that handles session registration, status tracking, coordination between tenancies, and cleanup operations. By consolidating these multiple functions into a single service, the patent reduces overall system complexity compared to having separate mechanisms for each function distributed across data centers.
3Ease of operation
If multiple sessions are allowed for the same tenancy, then user accessibility and convenience are improved, but security risks and resource wastage increase
Solution Approach 1:
The centralized session management service continuously monitors the global state of sessions and provides feedback mechanisms to detect conflicting or unauthorized session attempts. When a user attempts to access a tenancy, the service checks the current session state and returns appropriate responses, enabling the system to prevent security risks while maintaining legitimate user access.
Solution Approach 2:
The system dynamically manages session states based on real-time conditions. The centralized service can activate or deactivate sessions, coordinate between multiple tenancies, and adjust access rights as needed. This dynamic approach allows the system to adapt to changing user needs while maintaining security through centralized control of session lifecycles.
Data Source
AI summary
Techniques are described that enable, in a multi-region cloud environment, information regarding one or more tenancy sessions that a network access program (e.g., a browser) participates in to be efficiently stored in a centralized location. The centrally stored sessions information can then be used for various purposes such as for restricting the number of tenancy sessions using a network access program, sessions cleanup, and other sessions-related tasks. In certain implementations, the centrally stored sessions information is used to prevent the network access program from opening multiple sessions for the same tenancy. In such implementations, for a particular tenancy, the network access program is allowed to have only one active session for the particular tenancy at a time. The centrally stored sessions information facilitates efficient sessions management including session cleanup after a session is closed.
