What tech stack would you recommend for building a real-time multiplayer online poker game?
Briefly

Building a real-time multiplayer online poker game requires careful consideration of technology stacks that ensure performance, maintainability, and scalability. Recommended solutions include Node.js with Socket.IO for handling real-time WebSocket communication, and a database combination of PostgreSQL and Redis to efficiently manage game states and temporary data. Front-end options include React for browser-based experiences or Unity for more immersive app-based interfaces. To manage scalability and ease of deployment, embracing Docker and Kubernetes is also advisable, providing both reliability and quick adaptability to player demand.
Choosing Node.js + Socket.IO for WebSocket communication proved to be robust due to its non-blocking I/O, ensuring real-time handling of concurrent player interactions effectively.
Opting for PostgreSQL alongside Redis allows you to manage both persistent data and temporary in-memory states, striking a balance between reliability and speed.
Using Docker and Kubernetes for deployment not only simplifies scaling but also enhances maintainability by standardizing your development and production environments across different platforms.
Incorporating a React front-end can help in building a dynamic user interface, while Unity would add a richer gaming experience, especially if considering a mobile app.
