Keynote: Is it Reactive or Eventful? Aren't they the Same? - Mary Grygleski, Senior Developer Advocate, DataStax

Reactive and Event-driven Systems appear to have different definitions, but a closer examination of both sets of principles shows that they share a lot in common. So is that just a matter of semantics, or what are their differences, if any? We'll go through each and also find their similarities and the goals that they share in the current Cloud Native era in computing history. We'll also take a look to see the challenges that these systems have, not so much as the algorithms inside them, but the adoption by more developers, and what we may be able to help to increase a wider adoption, especially in the business world.

Keynote: We Are Drowning in Complexity. Can We Do Better? - Jonas Bonér, President and Chief Executive Officer, Lightbend

Today’s vast cloud-native infrastructure ecosystem is excellent. Unfortunately, it has grown very complex and hard to navigate. What tools to use for what job? How to compose them into a single coherent system? How to ensure the application’s guarantees and SLAs holistically? It can easily be overwhelming, and a lot falls on the Ops/SRE team that needs to manage it all.

Serverless to the rescue? Yes and no. It does provide a fantastic promise of a better DX for developers. But it has fallen short of this promise, stopped in its tracks halfway there.

Can we do better? Definitely. What we need is a new category of managed platforms that do full “vertical integration” of all infrastructure; providing a simple and high-level programming model allows the developer to focus on just three things: API definition, domain data, and business logic—i.e., working on direct business value. The rest, all of the rest, should be outsourced to the platform itself. Let me show you what I mean.

Streaming Graphs, Because We Can't Afford to Query Any More - Ryan Wright, thatDot

If you've ever tried to interpret data from an event stream, you've probably had to join multiple events into larger combinations that explain more. So where do you store the parts while assembling the whole? In RAM forces time-windowing that drops results, relational stores need expensive joins, key-value stores are hard for complex patterns, and graph databases are expressive but way too slow. Quine (https://quine.io) is a new open source "streaming graph" which feels like using a graph database but scales to millions of events per second. It works by putting the query execution inline with the event stream. High-volume events stream in, real-time answers to graph queries stream out. Built on top of Akka with an event-sourced persistence model, Quine is a new reactive architectural component for next generation streaming data pipelines.

WebAssembly for a Reactive Internet of Things - Colin Breck, Tesla

WebAssembly was originally used to run code in languages other than JavaScript in a web browser. The browser demands efficient and secure computation which makes WebAssembly equally promising for cloud services and edge computing. This talk will introduce WebAssembly from the point of view of a systems programmer, rather than a web developer. It will include an example of using WebAssembly in the cloud to continue the trend of abstracting more of the run-time into the infrastructure and a motivating example to demonstrate how WebAssembly can be used to flexibly and securely move code from the cloud to the edge. It will conclude with observations and advice and highlight unsolved problems with this emerging technology. WebAssembly has the potential to be the platform executing an enormous amount of IoT computation. It can be used as a product differentiator to provide a competitive advantage by helping design systems with reactive principles like efficient execution, accepting failure, decoupling space and time, and allowing code to be adapted quickly and responsively.

The End of the Data Ice Age - Hugh McKee, Lightbend

Why, in the third decade of the 21st century, after 80 years of writing software, data continues to live in two states, hot data in the compute space and cold data in the persistence state? Of course, data is created and manipulated while in a hot state. Ideally, all data would exist entirely in a hot state when you think about it. However, the reality is that due to the way most computers work, it is necessary to keep only the data that is actively in use in a hot state and push all inactive data out to a cold state persistence layer. This hot and cold data perspective raises the question of why we still have to focus so much attention and effort on dealing with data movement between these two states at the software level. In this talk, we will examine what has led us to this point, why we seem stuck here and look at some possibilities for moving forward. You also see real Java demo examples of an event-driven hot state software approach that inspired this rant and line of thought about seeing data in a hot and cold state way and the profound impact on how we develop software.

The Two-and-a-Half Ton Digital Twin: Automotive Applications of the Actor Model and Reactive Streams - Doug Mutart, General Motors

The next generation of connected, electric, and autonomous vehicles are driving the automotive industry to adopt digital twin technology and reactive architectures at significant speed and scale. This is happening in broad and challenging contexts such as automotive assembly, the software-defined vehicle, active safety and autonomous driving systems, and even motorsports racing and spans embedded, edge, cloud, and enterprise environments. Actor systems and reactive streams now enable device-level diagnostics and prognostics, machine learning, simulation and training, activity-based and crowd-sourced intelligence, and so much more. Doug's talk will discuss the domain-driven design of digital twins in several of these scenarios, investigate some of the reactive streams integrations that inform their behavior and state, and then conclude by providing some perspective on the opportunities, obstacles, and possible outcomes of this exciting journey.

Building a Pluggable, Cloud-native Event-driven Serverless Architecture - Daniel Farrelly, Inngest

Building out Reactive systems can be a lot of work. There’s a lot of infrastructure to set up and designing a system to be resilient, responsive, and elastic requires experience and time that not every team has. We built Inngest to be an open source, cloud-native system that enables anyone to build Reactive architectures. Designed to be pluggable with your favorite messaging service like Kafka, NATS or PubSub and your favorite container orchestration like Kubernetes, Nomad, or ECS. We’ll walk through how the system was designed, how you can deploy it yourself, and the plans to make it runnable on any cloud (and even your laptop!).

COTS in a Reactive Architecture - James Lovell, Improving Ottawa (YoppWorks)

We will be discussing a pattern to integrate a COTS (Commercial Off The Shelf) solution within an enterprise in a reactive way. In many cases it makes sense for a business to acquire a COTS solution to solve a particular business need. However, rarely are these systems implemented in a reactive way, making it challenging to work with when you are trying to make your enterprise more reactive. This pattern identifies a system within an enterprise landscape that the business finds value in and elevates it without rewriting it. The issue we are trying to solve is to make it fit safely within the rest of the enterprise, not strangle it out. We are trying to clarify its place and magnify its value for the enterprise. In other words, we want to bring appropriate focus to the system by defining its purpose, detangling it from the rest of the enterprise, and elevating it to a position where it can provide the value it was acquired for.

Serverless - The Problem Reactive Was Looking For - James Roper, Lightbend

For many years Reactive systems were a niche solution that helped a handful of companies that had harder problems than everyone else to solve. For everyone else, Reactive was a solution looking for a problem. Well that problem has now arrived in the mainstream. Serverless platforms may well abstract away the responsibility of developers and administrators to run and maintain servers, but for a system to work in that environment, it has to be architected to handle that. It has to stay responsive when platform automation underneath it is scaling up, scaling down, rebalancing, applying updates, and failing as all systems fail. Serverless is the perfect problem that Reactive architectural patterns were designed to solve. In this talk we'll run through how Lightbend's new Reactive serverless offering, Kalix, makes building reactive systems on a serverless platform simple, by abstracting away state as a platform managed resource, and allowing developers to write Reactive systems that need only focus on the business logic of their application.

Building Sports Betting Systems with Akka - Trevor Burton-McCreadie, Lunatech

The world of sports betting is a David and Goliath battle between the price setters and the price takers, with both sides looking to make a profit. Setting the prices are the Bookmakers - organisations with hundreds, sometimes thousands of employees. They must constantly tune those prices to balance profit against risk whilst shouldering a constantly-evolving regulatory burden. On the other side there’s a wide spectrum of people taking those prices: at one end there are those who place a bet to support their favourite team, whatever the expected outcome at the other a tiny minority who make a living by exploiting every mistake, mis-step or late move the Bookmakers make. This is a domain where the Reactive principles are vital to success: * Responsiveness - Systems must identify and act on opportunities that may only be available for seconds or less * Resilience - A single failure can wipe out several days' worth of profit * Elasticity - The number of markets varies considerably over time In this session I’ll present real-world use-cases that demonstrate how Akka has been used on both sides of this battle.

A Reactive Architecture Approach for a Tax Information System Modernization - Sergio Maurenzi, Peperina Software

Leading internet players like Amazon, Google, Netflix and others are raising expectations for the user experience of their applications. On the other hand, paying taxes is not inherently a pleasant experience for taxpayers. Therefore, designing a tax information system that is responsive, resilient and scalable is a duty rather than an option. Sergio Maurenzi will present his experience in modernizing a Tax information system through statefull services using technologies and architecture patterns such as Event-driven, Akka Actor Model, Akka Streams, Event Sourcing, CQRS, and others to improve the taxpayer experience.

BoF: Reactive Systems Fundamentals - Executive Overview - James Lovell, Improving Ottawa (YoppWorks)

How do you best introduce the concepts of reactive architectures to your executive team and technical leadership? How do you inspire technical teams to change the way they have been doing things for their entire career? How do you take all these ideas and condense them down in a way that is both consumable and exciting? How can you effectively convert fear, uncertainty, and doubt (FUD) into Fear of Missing Out (FOMO)? In this session we will have a conversation about things that have worked, and things that have not worked when proposing reactive architectures to an audience that isn't familiar with reactive fundamentals. We will explore new ideas to help communicate these big ideas in a way that inspires forward momentum. We will talk about the particular concepts that seem to cause concern when people are learning about reactive architectures and how to overcome these hurdles. We hope you all will join and add your voice to the conversation!
