Solution Overview

Problem

Conventional systems for managing secrets in data centers face challenges such as manual orchestration requirements, inefficiencies, and susceptibility to human error, leading to potential system outages and security non-compliances during secret renewal processes.

Innovation Solution

A datacenter secrets management service (dSMS) is introduced to autonomously orchestrate secrets renewal and distribution across a distributed computing environment, allowing for automated rollover of secrets like certificates and storage account keys, with features like secure blob delivery and staging to ensure seamless updates without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual orchestration is used for secret renewal, then human control and oversight are maintained, but system efficiency decreases and human error increases

Engineering Contradiction:
Improvesecret renewal efficiencyVSAvoiderror susceptibility
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system implements automated secret renewal where the secrets management service autonomously generates new secrets, rotates them, and updates distributed services without human intervention. The service monitors secret expiration and performs rollover operations automatically, eliminating manual orchestration while maintaining system control through automated workflows and validation mechanisms.

Inventive Principle:
Principle #25Self-service

2Productivity

If automated secret renewal is implemented, then operational efficiency improves, but system complexity increases

Engineering Contradiction:
Improvesecret renewal efficiencyVSAvoidorchestration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The secrets management service is designed as a universal system that handles multiple secret types (certificates, API keys, connection strings) and serves multiple functions (generation, rotation, distribution, revocation) through a single automated platform. This consolidates complexity into a centralized service rather than distributing it across multiple manual processes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The secrets management service acts as an intermediary between secret generation authorities and distributed services that consume secrets. It provides a standardized interface for secret delivery, version control, and rotation coordination, simplifying the overall system architecture by centralizing secret management operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If secrets are renewed proactively before expiration, then service continuity is maintained, but timing precision requirements increase

Engineering Contradiction:
Improveservice continuityVSAvoidrollover timing control
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary secret generation and validation before the current secret expires. New secrets are created, tested, and staged in advance, ensuring that a valid replacement is ready before the old secret becomes invalid. This proactive approach prevents service disruption while managing timing through scheduled rotation policies.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements a cushion period where both old and new secrets are valid simultaneously during the transition. This overlap window allows for graceful rotation, giving distributed services time to pick up new secrets without pressure of immediate expiration, thus reducing timing precision requirements while maintaining continuity.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Adaptability or versatility

If cross-scope secret distribution is enabled, then service connectivity across regions improves, but security management complexity increases

Engineering Contradiction:
Improvecross-region connectivityVSAvoidsecret management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The secrets management service provides universal secret distribution capabilities that work across multiple scopes (resource groups, regions, subscriptions) through a unified interface. The same service handles local and cross-scope secret delivery, eliminating the need for separate management systems and reducing overall complexity despite expanded distribution scope.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Various methods and systems are provided for autonomous orchestration of secrets renewal and distribution across scope boundaries. A cross-scope secrets management service ("SMS") can be utilized to store, renew and distribute secrets across boundaries in a distributed computing environment such as regional boundaries. In some embodiments, locally scoped secrets management services subscribe to receive updates from the cross- scope secrets management service. As secrets are renewed, they are automatically propagated to a subscribing local scope and distributed by the local secrets management service. In various embodiments, SMS can autonomously rollover storage account keys, track delivery of updated secrets to secrets recipients, deliver secrets using a secure blob, and/or facilitate autonomous rollover using secrets staging. In some embodiments, a service is pinned to the path where the service's secrets are stored. In this manner, secrets can be automatically renewed without any manual orchestration and/or the need to redeploy services.
