Guidance for Predicting Player Behavior with AI on AWS
Overview
How it works
These technical details feature an architecture diagram to illustrate how to effectively use this solution. The architecture diagram shows the key components and their interactions, providing an overview of the architecture's structure and functionality step-by-step.
Well-Architected Pillars
The architecture diagram above is an example of a Solution created with Well-Architected best practices in mind. To be fully Well-Architected, you should follow as many Well-Architected best practices as possible.
Operational Excellence
This Guidance employs AWS X-Ray and SageMaker Autopilot to enable observability and model experiment tracking. X-Ray traces AWS Lambda functions and logs the interactions with other AWS services, allowing you to visualize components to identify bottlenecks and troubleshoot errors. SageMaker Autopilot logs model training runs and candidate performance. You can view evaluation metrics and charts to understand how the best model was selected based on the data. Together, these capabilities allow transparency into system and ML model performance over time, facilitating quick diagnosis of issues and informed model and architecture optimization decisions, critical for cost-efficient operations.
Security
Amazon S3 with AWS Key Management Service (AWS KMS) ensures that data is encrypted at rest. Specifically, all ML training data and the trained ML models are encrypted using keys from AWS KMS. SageMaker endpoints encrypts all communication in transit. Together, these capabilities allow secure storage and communication of sensitive data like player information and ML models.
Reliability
SageMaker hosted endpoints automatically distribute hosted models across multiple AWS Availability Zones (AZs). This allows ML model inference requests to sustain AZ failures. SageMaker hosted endpoints effectively load balance inference requests from game clients and servers across multiple copies of the ML models. By spreading requests across AZs, this Guidance ensures continued service uptime and consistent real-time player predictions.
Performance Efficiency
This Guidance optimizes performance efficiency by leveraging SageMaker, which manages an elastic fleet of ML instances that scale up and down based on demand. By load balancing requests across a dynamic number of models, inference latency is reduced significantly compared to a single instance. Rather than overwhelming a single model and causing queueing delays, inferences are handled in parallel to improve throughput. The low latency and scalable capacity ensure real-time predictions that instantly inform game adaptations even under heavy loads, without performance degradation that could negatively impact the player experience.
Cost Optimization
By leveraging serverless and scalable inferences, this Guidance provides player predictions in a cost-efficient manner. Specifically, SageMaker automatically scales inference resources up and down to match real-time request demand. Serverless hosting means you pay only for the duration of each inference request. The ML models are used interchangeably for real-time and serverless hosting. This allows you to switch between modes to best align with the current scale and cost requirements. Games with volatile player activity can rely on inference at scale when hot while recouping costs when cooler. The optimization saves significantly on unused instances while still powering core player insights.
Sustainability
By eliminating resource idle time and right-sizing storage, this Guidance minimizes your carbon footprint to drive sustainability. To start, by using SageMaker serverless technologies for data processing and ML training jobs, you reduce any idle compute resources. And Amazon S3 implements lifecycle policies to archive infrequent access training data into energy-efficient storage tiers. You can select the appropriate Amazon S3 storage class to reduce your carbon impact based on access patterns. An AutoML serverless architecture also limits infrastructure maintenance and unnecessary provisioning. Together, these capabilities minimize resource waste, both compute and storage, to reduce energy demands and environmental impact.
