Conference Milan 2023 | Back-end

Description:
Deploying Node.js at scale is an art mastered by few. The most common problem is an exhaustion of resources that allows the application to denial of service itself. The result is Node.js systems that are massively overprovisioned, wasting enormous amounts of computing and memory - keeping most of them idle. In this talk, we will do some math, discover hard truths, and implement a fix.

Description:
Web applications are commonly vulnerable to several Distributed Denial of Service attacks, sometimes in unexpected ways. An example is the SlowLoris attack, an exploit that leads to service interruption by simply sending the data to the server as slowest as possible. In this talk I will tell the tale of how it took almost 13 years for Node to be completely protected by SlowLoris attack. I will also show that sometimes prioritizing performance can lead to incorrect fixes that can result in a false sense of protection. Check here the material of the speaker.

Description:
When your job title should be “bug fixer”, you eat spaghetti code for lunch and your logs are useless, then it’s time to stop and refocus: a Data-Driven approach is what you need to turn your day around! This is why we developed Trace Lib, an AWS serverless based service designed to provide a high-capacity log storage and query system, hosting millions of tracing events and offering easy querying through an SQL-like API. Our use case addresses the need for observability in complex flows that exist within a hybrid product ecosystem, in a cost effective solution that definitely made our day!

Description:
Bun, Deno, and many other JavaScript runtimes have been hyped, but do you know why? In this talk, attendees will learn the concepts used to create a new JavaScript runtime. They're going to go through an example of how to make a JavaScript runtime by following what's behind the scenes on the Node.js project using C++. They'll learn the relationship between Chrome's V8 and Libuv and what makes one JavaScript runtime better than others. This talk will cover the following topics: - What's a JavaScript Engine - V8 - Why Node.js uses Libuv - How to create a JS Runtime from scratch
