Overview
This Guidance demonstrates how to build an event-driven, serverless sportsbook application to help sports betting operators handle spiky, seasonal traffic. It addresses challenges like rapid market entry, development inconsistencies, complex integrations, and scaling difficulties. Leveraging microservices, serverless computing, and event-driven messaging, the Guidance helps operators overcome limitations of traditional online sportsbook platforms, such as the inhomogeneity of development environments and the need to over-provision to meet the unique demand characteristics brought on by seasonal sporting events. By using this Guidance, sports betting operators can deploy a flexible, cost-optimized, player-centric approach that reliably scales to improve the customer experience.
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.
Step 1
Players connect to the application through a web user interface.
Step 2
An Amazon CloudFront distribution serves the user interface. Amazon Simple Storage Service (Amazon S3) provides the origin for static content.
Step 3
AWS AppSync resolves all queries, mutations, and subscriptions for both the front-end and back-end using GraphQL APIs. Amazon Cognito provides secure access to various APIs and data sets.
Step 4
AWS Lambda functions provide the application layer for business processes like player account management (PAM), betting, wallet, trading, live market applications, and events. Amazon DynamoDB stores user and market data, which the application uses to power the application.
Step 5
Amazon Simple Queue Service (Amazon SQS) and Amazon EventBridge provide notifications about state changes across the system such as wallet deposits or the end of sporting events. AWS Step Functions orchestrates state changes between different parts of the system.
Step 6
Third-party data providers push data streams containing fixture updates and live market odds to EventBridge. The application layer updates players' views through subscription.
Step 7
AWS AppSync allows admins to suspend markets in near real-time, immediately stopping players from placing bets on selected markets to reduce risk exposure.

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
Amazon CloudWatch helps you gain deep insights into your application's performance and behavior. CloudWatch monitors your system's health, helping you quickly identify and resolve issues. Automate your deployments using AWS CloudFormation for consistent and repeatable infrastructure provisioning to support your evolving business needs.
Security
Protect your application with AWS Identity and Access Management (IAM), Amazon Cognito, and DynamoDB. IAM enables fine-grained access controls, Amazon Cognito secures user access by providing mechanisms for controlling external API access, and DynamoDB encrypts data at rest, safeguarding your sensitive information.
Reliability
Build a resilient, fault-tolerant architecture using EventBridge, Lambda, DynamoDB, Amazon SQS, and CloudFront. EventBridge and Amazon SQS decouple your components to reduce single points of failure. Lambda scales automatically so you don’t have to provision or manage servers. CloudFront delivers static content reliably from a global network, improving availability and reducing latency.
Performance Efficiency
Lambda allows you to run lightweight code on highly available compute infrastructure to help you respond quickly to events. DynamoDB offers a fast, serverless NoSQL database with consistent millisecond performance, maintaining performance regardless of scale. Amazon SQS and EventBridge allow non-blocking integrations between applications.
Cost Optimization
Serverless services like Lambda and AWS AppSync align costs with actual usage, following a pay-as-you-go pricing model, meaning you only pay for the services you use. DynamoDB has an on-demand mode and automatic scaling so that you only pay for the capacity required at any given time. CloudFront offers a global edge network that minimizes data transfer costs by reducing the distance data needs to travel to reach end-users.
Sustainability
Enhance the sustainability of your workload by using Lambda and DynamoDB. Lambda minimizes idle compute resources, and DynamoDB scales on-demand, reducing over-provisioning.
