Solution Overview

Problem

Datacenters face challenges in providing secure and scalable infrastructure that adheres to user and data privacy regulations, with existing load balancers offering poor functionality during configuration changes and lacking support for growth and compliance features.

Innovation Solution

A scalable application gateway for security and privacy that integrates a layer four load balancer with processing pods and a management backend, supporting features like service discovery, rate limiting, and web application firewall, allowing configuration updates without restarting, and supporting multiple protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional load balancers are used with configuration file modifications, then basic load balancing functionality is provided, but configuration changes require restarting the load balancer causing traffic loss and service interruption

Engineering Contradiction:
ImproveConfiguration update continuityVSAvoidService availability during configuration changes
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system transitions from static configuration files requiring restarts to dynamic configuration management where the management backend can update processing parameters in real-time without service interruption. The load balancer continuously receives updated configuration from the management backend, enabling dynamic adaptation while maintaining service availability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The management backend acts as an intermediary between the configuration system and the load balancer. It receives configuration updates, processes them, and pushes updated processing parameters to the load balancer without requiring the load balancer to restart, thus maintaining service continuity during configuration changes.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If native layer 7 load balancing solutions are employed, then traffic routing is provided, but functionality is limited and cannot fulfill business growth needs

Engineering Contradiction:
ImproveLoad balancer functionalityVSAvoidSystem architecture
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The load balancer is enhanced with multi-functionality to handle not only basic traffic routing but also advanced features such as SSL termination, content switching, health checks, and integration with the management backend for dynamic configuration. This universal design allows the same system to serve both simple and complex business requirements.

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

Solution Approach 2:

The system is segmented into distinct functional components: the load balancer handling traffic routing, the management backend handling configuration and control, and processing pods handling application logic. This segmentation allows each component to be optimized independently while working together to provide comprehensive functionality.

Inventive Principle:
Principle #1Segmentation

3Reliability

If datacenters operate in regions with strict privacy regulations, then user data protection is required, but secure infrastructure is difficult to provide due to wide distribution nature

Engineering Contradiction:
ImproveUser data securityVSAvoidTrusted infrastructure setup
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The management backend serves as a trusted intermediary that centralizes control and configuration management. It enforces security policies, manages SSL certificates, and controls access to sensitive information, thereby providing a trusted infrastructure layer that works across the distributed datacenter environment while maintaining user data protection.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements local quality by allowing different security configurations and processing parameters to be applied to different regions, datacenters, or service pods. Each local instance can be configured with appropriate security measures for its specific regulatory environment while maintaining consistency with overall system security policies.

Inventive Principle:
Principle #3Local quality

AI summary

Systems and methods directed to an application gateway for security and privacy that supports security and compliance monitoring between production environments and virtual private clouds are described. In examples, the application gateway for security and privacy supports security and compliance logging making such information available to administrators and auditors; accordingly, the administrators and auditors can determine how the application gateway for security and privacy is behaving in a very detailed way. For example, by providing access to security and compliance logs, administrators and auditors can verify that the application gateway is not behaving in a malicious manner, such as but not limited communicating with an unauthorized host. In addition to including a user-friendly management interface that allows a user access to modify existing configurations in real-time, the application gateway for security and privacy may scale in a secure manner to support increasing and decreasing traffic demands.
