The document outlines the agenda for a programming conference on November 7-9, featuring workshops on building an ideal betting stack led by Chandru Mullaparthi, a veteran in the telecom and betting industries. It discusses various programming languages and technologies vital for modern application development, including Erlang, Go, Apache Kafka, gRPC, Prometheus, and OpenTracing. The focus is on creating a robust, legacy-free architecture for betting applications that incorporate essential database and middleware solutions.

- 2. Building an ideal betting stack Chandru Mullaparthi
- 3. About me • Started programming when I was about 12 • Started getting paid to do it when I was 21 • Spent 18 years in Telecoms • Involved in the betting industry since 2014 • Currently working on an advertising startup • Provide consulting for Erlang Solutions
- 4. What would a betting stack with no burden of legacy look like?
- 6. Erlang / OTP • Concurrency oriented • Functional Programming • Expressive • Optimised for multicore • Erlang is the language • OTP is a set of applications truewave.io www.erlang-solutions.com
- 7. • Hip young offspring of Erlang • Ruby-like syntax • Compiles down to Core Erlang • Runs on the BEAM VM truewave.io www.erlang-solutions.com
- 8. Go • A better C • Good support for concurrency • Excellent cross-platform support • Excellent tool chain truewave.io www.erlang-solutions.com
- 10. Apache Kafka • High performance messaging platform • Ideal glue for interconnecting systems asynchronously • Persistent, replicated queues • “At least once” or “exactly once” semantics • Event sourcing Source: https://confluent.io truewave.io www.erlang-solutions.com
- 13. • Generic RPC mechanism • Programming language agnostic • HTTP/2 transport protocol • Bi-directional streaming & integrated auth • gRPC-REST gateway Source: https://grpc.io truewave.io www.erlang-solutions.com
- 14. GRPC • Unary RPC (traditional client-server request / response) • Server Streaming RPCs (client sends request, servers sends a stream of messages as response) • Client Streaming RPCs (client writes a sequence of messages as request, and waits for server response) • Bidirectional streaming (like when you and your spouse have an argument)
- 16. Prometheus • Monitoring and Alerting system • Multi dimensional data model • Powerful query language • Single binary - requires only disk • Pulls metrics • CNCF project Source: https://prometheus.io truewave.io www.erlang-solutions.com
- 17. OpenTracing • An open standard for distributed tracing • Enables easy visualisation of execution flow in distributed systems • Visualisation using Zipkin, Jaeger etc. Source: https://opentracing.io
- 21. • Distributed Key/Value store • Useful as a centralised configuration store • Ability to push updates to config • Useful to implement distributed coordination truewave.io www.erlang-solutions.com
- 23. PostgreSQL • High performance • Large installed base • Actively developed • License free! truewave.io www.erlang-solutions.com
- 24. Riak KV • Distributed NoSQL database • Various control levers to tradeoff consistency for availability • Built-in CRDT support! • Based on Amazon’s dynamo paper • Multi datacenter replication to be available as open source soon! truewave.io www.erlang-solutions.com
