The Client:
NDA. Our client is a European game development company operating a large-scale, real-time online multiplayer game platform.
Scalable Architecture for a High-Load Online Game Platform
The Business and Technical Challenges:
-
the primary challenge was scaling the platform to support high traffic without compromising performance or stability
-
the platform needed to support thousands of concurrent users with minimal latency, reliable fault tolerance, and the ability to scale rapidly as the user base grew
-
backend of high load website/games platform
The Solution:
Our senior engineer was embedded into the client’s development team to design and implement of backend microservices using Scala. These services were responsible for real-time communication between players, game state synchronization, and session management. Although the focus was primarily backend, the work also extended into front-end interaction layers to ensure seamless integration with the real-time infrastructure.
The Tech Stack Used in the Project:
-
Microservices
-
Scala
-
AWS
-
Kubernetes
-
Kafka
-
WebSockets
The Result:
Key Outcomes:
-
Designed a scalable architecture with fault-tolerant microservices.
-
Handled real-time user interaction using WebSockets and event-driven patterns.
-
Prepared the backend for data warehousing, enabling future analytics and personalization features.
-
Enabled the client to scale rapidly without sacrificing performance or stability.
We implemented scalable microservice patterns, message queues, and WebSocket handling mechanisms to ensure low-latency communication at scale.
Our architectural decisions were made with a data-first mindset — laying the groundwork for centralized data pipelines, real-time analytics, and future integration with a data warehouse to become the single source of truth for gameplay metrics, user behavior, and monetization insights.
The Data Security:
-
Encryption in Transit
-
Anonymised users metrics
By designing the data-oriented architecture of an online game platform, our client has got to make data-driven decisions and analyze users behaviour in detail, which allows them to increase sales.
