Multi-tenant Keystore Management for Cloud Integration Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Provisioning microservices and obtaining certificates in a multi-tenant, microservice architecture-based cloud computing environment is a difficult, manual, and time-consuming process, especially in multi-cloud setups, requiring human intervention for life cycle management such as renewal and deletion of certificates.
Innovation Solution
A multi-tenant keystore management service is automatically deployed to receive and manage signed security certificates from a trusted authority, automating the provisioning of an initial keystore for integration services, supporting life cycle management, including certificate renewal and revocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual provisioning of integration service and certificates is performed by administrator, then security can be maintained through controlled certificate issuance, but the process becomes time-consuming and operationally complex
Solution Approach 1:
The system performs preliminary actions by automatically deploying a multi-tenant keystore management service that pre-configures keystores and automatically requests signed certificates from trusted authority platforms before the integration service is fully operational, eliminating the need for manual administrator intervention during deployment
Solution Approach 2:
The multi-tenant keystore management service enables self-service by automatically managing the certificate lifecycle including requesting certificates from trusted authorities, receiving signed certificates, adding them to keystores, and deploying them to tenants without requiring manual administrator intervention for each operation
2Reliability
If manual certificate management is implemented, then control over certificate lifecycle can be maintained, but operational complexity increases significantly
Solution Approach 1:
The patent merges multiple separate operations (keystore creation, certificate requesting, certificate validation, certificate deployment) into a single integrated multi-tenant keystore management service that handles the entire certificate lifecycle automatically, reducing operational complexity while maintaining control
Solution Approach 2:
The multi-tenant keystore management service provides universal functionality by handling multiple tasks including keystore provisioning, trusted authority communication, certificate management, and deployment across multiple tenants through a single service platform, eliminating the need for separate manual processes
3Productivity
If automated multi-tenant keystore management service is deployed, then provisioning efficiency is improved and manual intervention is reduced, but system architecture complexity increases
Solution Approach 1:
The multi-tenant keystore management service acts as an intermediary between the integration service deployment process and the trusted authority platforms, automatically handling certificate requests and management while simplifying the overall system architecture by centralizing these functions in a dedicated service layer

AI summary
According to some embodiments, methods and systems may include a provisioning application platform processor to receive a user request for an integration service. The provisioning application platform processor may then transmit information to a platform resource manager processor to facilitate creation of a plurality of microservices resulting in implementation of the integration service for a tenant associated with the user. A multi-tenant keystore management service, automatically deployed upon implementation of the integration service, may automatically call a trusted authority platform. The multi-tenant keystore management service may then receive a signed security certificate from the trusted authority platform and add the signed security certificate to a keystore deployed to the tenant.
