Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in minimizing latency and improving security by reducing inter-datacenter communications in distributed cloud settings, where hotspots and uneven data distribution can lead to inefficiencies and increased latency.
Innovation Solution
A system that divides a database into shards distributed across multiple data centers, uses a machine learning model trained on labeled input data to predict which data center will have the largest number of leader shards to process a request, and sends the request to that data center to minimize inter-datacenter communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If requests are distributed across multiple data centers in a sharded database system, then system capacity and scalability are improved, but inter-datacenter communication latency increases and security is reduced
Solution Approach 1:
The database is segmented into shards that are distributed across multiple data centers, allowing the system to scale while maintaining manageable data units. Each shard can be independently managed and placed in appropriate data centers based on access patterns.
Solution Approach 2:
A machine learning-based load distributor acts as an intermediary between request sources and data centers. It predicts which data center will have the required shards and routes requests accordingly, reducing inter-datacenter communication by selecting optimal data centers in advance.
2Adaptability or versatility
If shards are distributed across multiple data centers, then system scalability is improved, but the number of inter-datacenter communications increases reducing security
Solution Approach 1:
The system performs preliminary analysis using a trained machine learning model to predict which data center will contain the required shards before routing requests. This advance prediction allows requests to be directed to the correct data center upfront, minimizing inter-datacenter communications and associated security risks.
Solution Approach 2:
The load distributor uses feedback from the machine learning model's predictions to continuously optimize request routing decisions. The system learns from past request patterns and shard locations to improve its ability to direct requests to the correct data centers, thereby reducing inter-datacenter communication frequency.
3Productivity
If a machine learning model is used to predict the optimal data center for request processing, then request processing efficiency is improved, but system complexity increases
Solution Approach 1:
The machine learning model automatically analyzes request patterns, shard locations, and data center performance metrics to make routing decisions without manual intervention. The system self-optimizes by learning from historical data, reducing the need for complex manual configuration and management.
Solution Approach 2:
The patent replaces traditional mechanical load balancing methods (such as round-robin or least-connections algorithms) with an intelligent machine learning-based prediction system. This substitution enables more accurate predictions of shard locations and optimal data center selection, improving request processing efficiency while the automated nature of the ML model keeps operational complexity manageable.
Data Source
AI summary
A system can divide a database into a group of shards that are distributed among a group of data centers. The system can train a machine learning model on a group of labeled input data, wherein the group of labeled input data comprises respective requests to operate on the database, and wherein the respective requests are labeled with respective shards of the group of shards used to process the respective requests, and to produce a trained machine learning model. The system can, after training the machine learning model, receive a request. The system can process the request with the trained machine learning model to predict that a data center of the group of data centers will have a largest number of leader shards of the group of shards to process the request. The system can send the request to the first data center to be processed.
