Tenant-to-Tenant Failover in Multi-Tenant Cloud Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-tenant cloud computing environments, the current state of technology lacks effective mechanisms for tenant-to-tenant failover, which can lead to service disruptions when a primary tenant becomes unavailable, impacting other tenants and compromising system reliability.
Innovation Solution
Implementing a system that identifies a primary and secondary tenant within the multi-tenant cloud computing system, synchronizing resources between them, and automatically switching to the secondary tenant when the primary tenant becomes unavailable, ensuring seamless service continuity without disrupting other tenants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a primary tenant is designated to provide business functions in a multi-tenant cloud computing system, then service functionality is improved, but system reliability deteriorates when the primary tenant becomes unavailable
Solution Approach 1:
The system designates a secondary tenant in advance as a backup provider before any failure occurs. This preliminary action ensures that when the primary tenant becomes unavailable, the secondary tenant is already prepared and positioned to take over the business functions immediately, thus resolving the contradiction between maintaining service functionality and ensuring system reliability.
Solution Approach 2:
The system introduces a failover mechanism as an intermediary layer between the primary tenant and the business functions. This mediator monitors the primary tenant's availability and orchestrates the transition to the secondary tenant when needed, ensuring continuous service delivery and resolving the reliability issue without affecting the primary tenant's normal operation.
2Reliability
If tenant-to-tenant failover mechanisms are implemented, then system reliability is improved, but device complexity increases
Solution Approach 1:
The secondary tenant is designed to be universally capable of providing the same business functions as the primary tenant. This multi-functionality allows the same tenant infrastructure to serve both as a primary provider and a backup provider, reducing the need for dedicated backup systems and thereby limiting the increase in device complexity while improving reliability.
3Duration of action of stationary object
If automatic switching between tenants is implemented, then service continuity is improved, but ease of operation deteriorates due to automated control complexity
Solution Approach 1:
The failover system is designed to be self-managing, automatically detecting when the primary tenant is unavailable and initiating the switch to the secondary tenant without human intervention. This self-service capability ensures continuous service delivery while minimizing the operational burden on system administrators, as the automation handles the complexity of monitoring and switching internally.

AI summary
Systems, methods, and apparatuses for implementing tenant-to-tenant failover in a multi-tenant could computing environment. An exemplary system having at least a processor and a memory therein includes means for identifying a first one of a plurality of tenants in a multi-tenant cloud computing system as a primary tenant for providing a function, identifying a second one of the plurality of tenants in the multi-tenant cloud computing system as a secondary tenant for providing the function should the primary tenant become unavailable, providing the function in the multi-tenant cloud computing system via the primary tenant when the primary tenant is available, and switching to providing the function in the multi-tenant cloud computing environment via the secondary tenant when the primary tenant is unavailable and the secondary tenant is available.
