Backend

We use Amazon Web Services for the Back End in the development of Battle Of Leader. We use AWS Lambda, which is an event-driven, serverless computing platform provided by Amazon as part of Amazon Web Services. Therefore, we can automatically manage the computing resources required and manage the running code in response to events.

GraphQL provides a complete and understandable description of the data in your API, gives customers the power to ask exactly what they need, nothing more, makes it easy to develop APIs over time, and provides powerful developer tools. For game applications it is very important to have this client-side flexible implementation.

· Managed Blockchain: To support our diverse needs in gaming applications, we need a central ledger database that maintains an immutable and cryptographically verifiable record of transactions. The notebook technology will be selected later.

· Analytical Zone Technologies:

- Database Structure: (Recommended with Kafka and MongoDB) ClickHouse is a fast, open source, column-oriented database management system that allows to generate analytical data reports in real time using SQL queries.

- Dashboard: Grafana is a multiplatform open source analytics and interactive visualization web application.
