Challenges in Building Multi-Cloud-Provider Platform With Kubernetes

I am a Programmer — Thu, 25 Mar 2021 02:17:58 +0000

Building a cloud-agnostic platform used to be a challenging task as one had to deal with a large number of different cloud APIs and service offerings. Today, there are many managed Kubernetes solution (e.g., Openshift, GKE, AKS, or EKS), it seems like developers could simply build a platform based on Kubernetes and be cloud-agnostic. While this assumption is mostly correct, there are still a number of differences and pitfalls when deploying across those managed Kubernetes solutions.

This talk discusses the experiences made while building the ArangoDB Managed Service offering across different Kubernetes distributions.

High Performance NodeJS Powered by Rust and WebAssembly

I am a Programmer — Mon, 01 Mar 2021 02:26:20 +0000

In the post Moore’s Law era, we need to squeeze more performance from existing hardware. Native code provides the best performance. However, the prevalence of native code on the server-side presents challenges to application safety and manageability. The advent of Rust and WebAssembly offers new ways for developers to write high performance yet safe Node.js applications. The Rust programming language is Stackoverflow’s most beloved programming language for the past 4 years. WebAssembly, on the other hand, provides a fast and lightweight virtual machine for running and managing Rust programs. Through open source bridges between Node.js and WebAssembly / Rust, we can now create JavaScript and Rust hybrid applications for Node.js, and shift computing loads to Rust functions. In this talk, I will go over the basics of Rust and WebAssembly, as well as their integration into Node.js. You will learn when and how to design a hybrid web application, how to code the high performance functions in Rust, and how to tie everything together in a Node.js JavaScript application. At the end of this talk, you will have all the open source tools and resources you need to get started on your own.

Modern JavaScript for Python Developers

I am a Programmer — Sun, 08 Nov 2020 08:12:47 +0000

JavaScript is the lifeblood of the modern web application. You need it to do anything remotely complex on the web.

But, for many Python developers, the modern JavaScript ecosystem is intimidating. The tools feel complex. There are often several ways to achieve the same goals. It's hard to choose a framework—and then once you do, it's hard to know exactly how to integrate it into a Flask or Django project.

This talk aims to demystify modern JavaScript for Python-minded developers. It will cover major advances that have been made to JavaScript in recent years and how you can use the JavaScript ecosystem - including tools like npm, webpack and babel - to write Python applications for the modern web.
