High Load Messaging Service for a Gaming Company

Client Our customer is a startup that created iOS and Android native apps combining real-time multiplayer gaming with a messenger. In these apps, people can play and at the same time communicate with friends one-on-one and in group chat rooms or make new friends in public chat rooms. Challenge As the number of users and their message history were growing, the customer started experiencing operational challenges related to the server-side and the performance of an Android native app. To scale and deliver new features faster, the company decided to replace the monolith server-side written in the Dart programming language with microservices. The customer’s team also needed an admin panel to maintain the app more effectively. Apart from the server-side migration, the customer wanted to add new functionality to the Android client app and resolve issues such as bugs, crashes, and slow rendering. The engineers at EffectiveSoft joined the client’s team to: write lightweight microservices using the Go programming language (also referred to as Golang), create an admin panel for managing all microservices, and participate in the further development of an Android app. Result Our engineers have been working as part of the customer’s team for almost 4 years. After migration to microservices: -the time to market shortened as it became easier to develop, test, and deploy the app -the app’s resilience improved as independent communicating services are easier to change, maintain, and scale. The work on stabilization, optimization, and advancement of the Android client app resulted in: -a higher crash-free rate – from 95% to 99.7% -a consistently high frame rate for users with a lot of data on the screen -organic growth of the app’s audience -revenue generation from in-app purchases.
