Hop on the Serverless adventure

Serverless is the new black - I can deploy my application to the cloud without ever worrying about infrastructure. We all remember the days when we had to spend hours and hours configuring and debugging web servers when all we wanted was to just code and test our app. Those days are long gone and it’s time for us to unlearn how to provision and manage infrastructure while focusing on building and scaling applications.

“Serverless architectures refer to
applications that signiﬁcantly
depend on third-party services
(knows as Backend as a Service
or "BaaS") or on custom code
that's run in ephemeral
containers (Function as a Service
or "FaaS")”

“Serverless computing has made
its way into the enterprise because
it simpliﬁes deployment and
allows developers to focus more
on application features than on
tasks such as provisioning VMs.
Emerging uses for serverless
technology include image
processing, task management,
workﬂows and notiﬁcations.”

Why Node.js?

@simona_cotin
•Javascript has a rich
ecosystem of libraries
and tools
•Enable FE developers to
build scalable backends
•Large use base -
javascript is the English
of languages
Why Node.js?

@simona_cotin
•Lightweight - helps reduce
cold start
•Commonly run in a
distributed, horizontally
scaled fashion
•Scripting means no
compilation required to
start from a portal
•Runs equally easy on most
OS’s
Why Node.js?

Progressive web apps (PWA) are becoming an industry standard for building web applications. With reliability, speed and immersive user experience in mind, PWAs help you reach a broader audience. In this session we will take an existing web app and convert it into a PWA. First, we'll make our application installable to homescreen by adding a Web App Manifest json file. Next, we'll focus on making our app reliable by enabling service workers inside our application and caching resources. Throughout this session we'll also learn how to use Lighthouse to test the performance of our PWA.

Getting started with Angular is now easier than ever... said no one ever. Yet with the right tool-set we too can create magic. When I code with Angular I can deploy to Azure within minutes. We'll go through a simple development to production workflow. First, we code with a little help from the Angular CLI. Then we build for production - Webpack to the rescue. We then push our code to Github and deploy it to Node on Azure. Mission accomplished, the application is now up in the cloud!

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system. About authorWith two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing.

Dubai, often portrayed as a shimmering oasis in the desert, faces its own set of challenges, including the occasional threat of flooding. Despite its reputation for opulence and modernity, the emirate is not immune to the forces of nature. In recent years, Dubai has experienced sporadic but significant floods, testing the resilience of its infrastructure and communities. Among the critical lifelines in this bustling metropolis is the Dubai International Airport, a bustling hub that connects the city to the world. This article explores the intersection of Dubai flood events and the resilience demonstrated by the Dubai International Airport in the face of such challenges.

Corporate and higher education. Two industries that, in the past, have had a clear divide with very little crossover. The difference in goals, learning styles and objectives paved the way for differing learning technologies platforms to evolve. Now, those stark lines are blurring as both sides are discovering they have content that’s relevant to the other. Join Tammy Rutherford as she walks through the pros and cons of corporate and higher ed collaborating. And the challenges of these different technology platforms working together for a brighter future.

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.
