Multi-tenant AMI Portal System for Meter Data Access

The patent merges multiple customer instances into a shared multi-tenant portal system where multiple customers access meter data through a common infrastructure. The system combines customer-specific data access requirements with shared backend resources (data repository, authentication services, device management), eliminating the need for separate complete instances for each customer while maintaining data security through tenant isolation mechanisms.

The multi-tenant portal system implements universality by designing a single portal instance that serves multiple customers simultaneously. The system provides customer-specific data access through universal components that are configured per tenant, allowing the same infrastructure to handle authentication, device management, and data retrieval for multiple customers without requiring separate instances, thereby improving resource utilization and cost efficiency.

The patent applies segmentation by dividing the multi-tenant system into isolated customer segments (tenants) with distinct data spaces and access controls. Each customer's device lists, meter data, and authentication credentials are segmented and isolated from other customers, ensuring that while the infrastructure is shared, the data security and access control remain robust through logical separation mechanisms.

The patent introduces intermediary components such as authentication services, authorization mechanisms, and device list management systems that mediate between multiple customers and the shared data repository. These intermediaries coordinate access requests, validate customer permissions, and manage device lists, simplifying access coordination while maintaining resource efficiency through centralized management rather than distributed instance management.
