Module 13: Networking Applications

Duration: 4-Hour Live Online Training

Alpinum’s Networking Applications Training is a practical live online module within the Software Development Programme. It builds on network programming fundamentals and helps participants engineer complete production-grade networked applications.

Build production-grade networked applications on top of the socket and protocol fundamentals from Module 6. Where Module 6 teaches the primitives how to move bytes over a connection this module engineers complete systems with them: servers and services that many clients depend on at once. The theme is concurrency, performance, reliability, and operating a networked application in production.

What You Will Learn

By the end of this training, you will be able to:

• Design application-layer protocols with framing, request/response, and streaming
• Choose server concurrency models: thread pools versus event-driven I/O (epoll, kqueue, io_uring)
• Engineer high-performance servers with non-blocking I/O, backpressure, and zero-copy
• Build HTTP and gRPC services at scale, including HTTP/2 and streaming RPC
• Implement real-time services with WebSockets and publish/subscribe
• Scale out with load balancing, reverse proxies, and service discovery
• Apply reliability patterns: timeouts, retries, circuit breakers, and graceful shutdown
• Secure and observe services with TLS, rate limiting, metrics, tracing, and load testing

Topics Covered

Session 1: Concurrency & High-Performance Servers

From Sockets to Services

• • Application-layer protocol design (framing, request/response, streaming)

• • Server concurrency models: thread-per-connection, thread pools, event-driven I/O

High-Performance Design

• • Non-blocking I/O, backpressure, connection pooling, zero-copy

• • epoll, kqueue, io_uring

Session 2: Scaling, Reliability & Observability

Services at Scale

• • HTTP and gRPC at scale: keep-alive, HTTP/2, streaming RPC

• • Real-time and streaming: WebSockets, publish/subscribe, chat and notifications

• • Load balancing, reverse proxies, service discovery

Reliability, Security & Observability

• • Timeouts, retries, circuit breakers, graceful shutdown, health checks

• • TLS termination, authentication, rate limiting, denial-of-service resistance

• • Logging, metrics, distributed tracing, load testing, and benchmarking

Practical Labs

• • Concurrent TCP server: compare a thread-pool model against an event-driven model under load

• • WebSocket real-time service (broadcast / chat)

• • Reverse proxy or load balancer sitting in front of several backends

• • Load test and benchmark throughput, latency, and connection scaling

Module Project: A high-performance, concurrent application server — Option A: a scalable chat / messaging server, or Option B: an HTTP / API gateway — handling many concurrent clients with graceful shutdown, timeouts and retries, TLS, and a documented throughput and latency benchmark. Reference tooling includes libuv or Boost.Asio (C/C++), Tokio with hyper or axum (Rust), FastAPI with uvicorn (Python), NGINX or Envoy, and wrk or k6. Prerequisite: Module 6 — Network Programming.
