The document discusses PayPal's adoption of Node.js for their web applications. It describes identifying customer needs like unifying teams around JavaScript, conducting a pilot project building an account overview app in both Java and Node.js, and showing that the Node.js version was built faster, with fewer lines of code, and could handle more requests. While adoption was not always smooth, with challenges around mindsets and frameworks, the pilot was successful and more apps are now being built on Node.js at PayPal.

The last two decades have been all about SaaS, with advantages that cannot be overstated. Except SaaS isn’t always an option, nor is it always the right choice: businesses in tightly regulated industries, or where information security is paramount, for example, will not - often can not - consider any software that isn’t under their control. For many software enterprises, this leads to the dreaded inevitability of on-premise deployment. Fortunately, the situation today is dramatically different to a scant few years ago, let alone a decade or two: the same technologies that enable SaaS have also radically transformed on-prem deployment. Modern tools like Docker, Consul, ELK and Kubernetes - to name a few - can be leveraged to completely transform the experience for both customers and vendors. In this talk we’ll contrast the challenges and advantages of SaaS and on-prem, see how things have evolved in recent history, and see how modern on-prem deployment can be, if not pleasurable, at least relatively painless.

There's a lot of cool JS frameworks out there and it seems you can't go more than a couple of weeks without a new one popping up. So what's special about React? In this session I will cover some of the basic principles of React and will show how React fits perfectly into the MVC pattern, giving you all the goodness of React on the client with the stability of .NET on the server. I will end up with some examples of how to implement this an MVC project using React.NET and TypeScript. More details at www.macsdickinson.com/talks/react

Azure Stack is the first product in a new category – the hybrid cloud platform. It is a radical new product that you can think of as delivering the cloud equivalent of a SAN. Delivering a set of IaaS/PaaS Services, APIs, PowerShell and tooling experiences that are consistent with Azure allows it to run solutions from the Azure Marketplace. This allows companies to focus their dev and ops teams on the things that move their business forward, building applications which drive customer value. This session focuses on what Azure Stack is and is not. It articulates the key values it delivers and use cases it enables.

Subject to the CAP theorem, NoSQL distributed systems have mostly chosen availability over consistency. This has been changing, yet many famous databases are still AP only. This talk includes a theoretical overview, and a practical look at the tradeoffs for your application and data between AP and CP modes. Also, how do different levels of consistency actually matter? Distributed data stores are subject to the CAP theorem, and historically NoSQL distributed systems have chosen availability over consistency. This has been changing, yet many famous databases are still AP only. In Eric Brewer's 2012 follow-up article about the CAP theorem he stated: "Availability is obviously continuous from 0 to 100 percent, but there are also many levels of consistency, and even partitions have nuances, including disagreement within the system about whether a partition exists." This talk will include a theoretical overview, but focus on the practical aspects of the theorem. * What are the tradeoffs between AP and CP modes? * How do they affect your application and data? * How do different levels of consistency actually matter?

The term “reactive” has lately become a buzzword, with a variety of definitions around the Web. When you hear reactive, what do you think of? Reactive Streams? The Reactive Manifesto? ReactJS? These terms may seem unrelated, but they share a common core concept. Reactive applications and reactive programming result in flexible, concise, performant code and are a superior alternative to the old standard thread-based imperative programming model. The reactive approach has gained popularity recently for one simple reason: we need alternative designs and architectures to meet today’s demands. However, it can be difficult to shift one’s mind to think in reactive terms due to how accustomed we’ve become to the imperative style. Stephen Pember explores the various definitions of reactive and reactive programming with the goal of providing techniques for building efficient, scalable applications. Steve dives into the key concepts of Reactive Streams and examines some sample implementations—including how ThirdChannel is currently using reactive libraries in production code. Steve looks at some of the open source options available in the JVM—including Reactor, RxJava, and Ratpack—giving attendees an idea of where to begin with the reactive ecosystem. If reactive is new to you, this should be an excellent introduction.

Securing service to service communication was never easy. Can we build a system that enforce good practices like least privilege and secure by default without affecting devlopement velocity? Apparently yes - and in this talk I’ll share how! Micro-services are social beings: they can’t function without talking with other services. Every microservice has its own domain, and it usually relies on other micro-services to function properly. But this also raises an interesting question: do we trust all of our micro-services? The truth is that not all micro-services are the same: some micro-services are more sensitive - for example, services that handle user data. Others are user-facing and therefore riskier. We cannot treat all services as equal. We need a good and robust mechanism to describe who can talk with who. At Soluto, we are dealing with this challenge for a while. In this talk, I’ll share the journey we went through until we found a solution we’re happy with: a simple and declarative system that allows services to define who can access them. Any dev can request access to any service, and the service owner can review it. In talk, I’ll share how we build this solution, using open source tools like Open Policy Agent, so you can easily build something similar.

Infrastructure code can really benefit from some proven object oriented design principles like SOLID and others. Instead of just thinking about automation, we need to design and build infrastructure software systems that are easy to understand, test and maintain Everyone talks about the fact that infrastructure should be programmatic and treated as a code, but often what this means is just writing a bunch of scripts to automate our deployments. By doing so, aspects like proper documentation, separation to modules , abstraction, even version control that are standard for "regular" software projects are omitted from infrastructure systems. This leads to cumbersome, monolith system - the very thing we are trying to resolve in the software design. I would like to discuss the basic software design principles like SOLID and DRY and how to apply them when automating our deployments, writing docker containers or writing our application stack.

This is the presentation given for the Docker Meetup in Cordoba, Argentina. Recording should soon be up on http://www.meetup.com/Docker-Cordoba-ARG/events/226995018/ Key Takeaways: Pick your Metrics! Automate It! Fail Bad Builds Faster! Deliver Faster with Better Quality! To the Docker Audience my main point was that: Just adding Docker doesn't give you free performance and scalability of your app. I walk through many examples of failing apps. What are the metrics that highlight the problem and how to automatically detect bad builds by looking at these Metrics along your Pipeline.

Created by Mozilla Research in 2012 and now part of Linux Foundation Europe, the Servo project is an experimental rendering engine written in Rust. It combines memory safety and concurrency to create an independent, modular, and embeddable rendering engine that adheres to web standards. Stewardship of Servo moved from Mozilla Research to the Linux Foundation in 2020, where its mission remains unchanged. After some slow years, in 2023 there has been renewed activity on the project, with a roadmap now focused on improving the engine’s CSS 2 conformance, exploring Android support, and making Servo a practical embeddable rendering engine. In this presentation, Rakhi Sharma reviews the status of the project, our recent developments in 2023, our collaboration with Tauri to make Servo an easy-to-use embeddable rendering engine, and our plans for the future to make Servo an alternative web rendering engine for the embedded devices industry.
