What It Takes To Properly Build Reactive Web Applications For The JVM

Manuel Bernhardt knows a thing of two about building distributed, Reactive web applications for the modern enterprise. Having recently published his own book on the subject, I wanted to sit down with him to ask him about what architects and developers should know about the traits of Reactive systems, why it's important to build Reactive systems using Play, Akka, and Scala rather than Spring and Java EE, how the open source community has wonderfully impacted the growth of these technologies, and whether he'd ever consider writing another book again. Enjoy the Q/A!

A New Trilogy: The Enterprise Architect's Intro to Microservices

Earlier this summer, Lightbend CTO & Co-founder (and creator of Akka) Jonas Bonér  and Enterprise Advocate Kevin Webber were seeing their vacation time more as a far-off dream than a plausible reality. Jonas had just published the free O'Reilly book titled Reactive Microservices Architecture––called "the best single source of the key ideas needed to design modern Reactive systems" by John Nestor––and we wanted to make it even easier to get the principles of microservices architectures into the hands of Enterprise Architects, CTOs, App Dev Managers and other decision makers. With the story of going Reactive with microservices in place, Jonas and Kevin set to work breaking down this concise, valuable book into a three-part series...

What Architects Should Know About Reactive Design Patterns

In this presentation by Dr. Roland Kuhn, we explore several architecture elements that are commonly found in reactive systems, like the circuit breaker, various replication techniques, and flow control protocols. These patterns are language agnostic and also independent of the abundant choice of reactive programming frameworks and libraries. They are well-specified starting points for exploring the design space of a concrete problem: thinking is strictly required!

Case Study: Samsung Strategy And Innovation Center Executes IoT Vision At Startup-Speed With Reactive Architecture

Jerome Dubreuil and his colleagues on the SAMI (Samsung Architecture Multimedia Interactions) team at Samsung saw a number of technical obstacles holding IoT developers back. The SAMI group made some key architecture decisions in the earliest days of building out an innovative ioT data platform, and from day one they knew that they would be building their platform following Reactive principles. Central to their efforts were the Scala and Play Framework for rapid prototyping and developer productivity, and Akka for the data transformation and WebSocket layers. Our case study looks at some of those key decisions that allowed SAMI to ship such an ambitiously scoped platform in less than two years.

The 7 Ways to Wash Dishes and the Case for Message-driven Reactive Systems

I’ve been working for several years to try to find a meaningful way to describe the core concepts of building efficient, Reactive applications - being asynchronous and non-blocking while minimizing concurrency and supporting linear scalability by enhancing parallelism. That is a veritable soup of esoteric terms that are difficult to grasp for even the most experienced developers. Yet understanding them is critical to building truly Reactive applications.

In the past few months, I think I may have found a way to express these concepts more clearly. It also highlights some other interesting concepts, such as pipelining, batching, fork/join and Amdahl’s Law via an everyday metaphor. This kind of real-world analogy has always helped me understand concepts, and when I’ve run through this one with customers, they’ve found it to be helpful as well.

Introducing "Reactive Revealed" - A Technical Webinar Series on Going Reactive for Architects and Developers

With the Reactive Manifesto now embraced by over 11,000 people and the Reactive Streams initiative in full swing with a 1.0.0 launch, we are seeing more interest in "Going Reactive" than ever before. Organizations large and small ask us questions like:

  • What does Reactive really mean and why should we care?
  • What does “Going Reactive” mean for our Development and Operations teams?
  • How can Reactive systems help us improve system resilience and scale elastically to accommodate bursty traffic? 
  • What are the business drivers and market forces that we should be aware of, and how can my organization start the journey towards modernizing our existing applications and infrastructure?

From Jonas Bonér, Viktor Klang and Konrad Malawski, co-authors of the Reactive Manifesto and contributors to the Reactive Streams initiative, we have set out to produce a three-part “Reactive Revealed” series to give an interactive opportunity for enterprise architects and software developers (we even have some goodness for Operations and Executives too) to get started with understanding Reactive from the beginning, providing an overview of the technological foundation behind it all.

12 Tips for Enterprise Adoption of Typesafe Reactive Platform with Play, Akka, sbt, Scala and Java

In April, 2013, we published a blog post about Enterprise Scala Adoption Tips, but the time has come for an update. Not only that, we need to focus on how to help enterprise organizations adopt Scala and also the Typesafe Reactive Platform in general. Many enterprises make the decision to leverage Akka and Play Framework from the Java API, which we fully support.

As more enterprise organizations adopt Scala/Akka/Play, we find it important to help them engage the community effectively. This involves providing them with information about where they can find resources to empower their developers to learn as much about these technologies as possible, as well as to directly engage with the community on a daily basis. By following these steps, the likelihood of successfully adopting these technologies is much higher.

Why managing Reactive systems is keeping your Operations team up at night

While Reactive application development is off to a roaring start and becoming mainstream, this leads to demands on Operations that are simply not met by yesterday’s software architectures and technologies. The pressure facing enterprises to manage resilient, responsive systems is brutal, yet most existing technologies available today are not designed to deploy and manage Reactive systems running on clusters. It’s due to this fact that Operations face a higher risk of downtime by using inappropriate tools/practices at a time when being unavailable is more costly than ever. So why is this happening? Well, it's not 2005 anymore–and why that's a problem for Operations is explained here...
