When systems reach this critical level of dynamism we have to change our way of modelling and designing them. It is now no-longer the static structural properties in space that define them but increasingly the systems relations in time that come to define how it functions. The appropriate systems architecture for this inherent dynamic nature to complex engineered systems is what is called event driven architecture. Event driven architecture or E.D.A. is a design pattern built around the production, detection, and reaction to events that take place in time. Information technology is key to enabling a new world of event driven architecture, when we start putting chips in all kinds of devices and objects, instrumenting our technologies and putting smart phones in the hands of many, the world around us stops being dumb and static and starts being more dynamic, adaptive, and things start happening in realtime. When the lights in my house or my garage door are instrumented with sensors and actuators, they no longer need me to turn them on. Instead they wait in what is called a restless state, listening for some event to occur and then can instantly respond. This is in contrast to many of our traditional system, where the components are constrained by some centralised coordination mechanism with information often having to be routed from the local level to a centralised control mechanism, then batch process and returned to the component to respond after some delay. the components within complex system are able to adapt locally, this means they can often act and react in realtime. Added to this is the fact that many of these complex engineered systems are loosely couples networks of unassociated components, they don’t really have any structure, sometimes they don’t even exist until some event actually happens. When I make a query on a search engine my computer might be coupling to a data centre in Texas but the next time I make the same query I might be interacting with a server in South Korea depending on the systems load balance at that instance in time the network’s structure is defined dynamically during the systems run time. An event-driven architecture consists primarily of event creators, event managers and event consumers. The event creator, which is the source of the event, only knows that the event has occurred and broadcasts a signal to indicate so. An event manager, as the name implies functions as an intermediary managing events, when the manager receives notification of an event from a creator, it may apply some rules to process the event but ultimately events are passed down stream to event consumers where a single event may initiate numerous downstream activities. Consumers are entities that need to know the event has occurred and typically subscribe to some type of event manager. So a quick example of this might be an online accommodation service, where event creators, that is property owners, broadcast the availability of their accommodation to the event manager, the online platform, which would aggregate these and event consumers, people looking for accommodation, could subscribe to the platform’s mailing list sending them notification for any new relevant listings.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Event-driven architecture (EDA), is a software architecture pattern promoting the production, detection, consumption of, and reaction to events. An event can be defined as "a significant change in state". For example, when a consumer purchases a car, the car's state changes from "for sale" to "sold". A car dealer's system architecture may treat this state change as an event whose occurrence can be made known to other applications within the architecture. From a formal perspective, what is produced, published, propagated, detected or consumed is a (typically asynchronous) message called the event notification, and not the event itself, which is the state change that triggered the message emission. Events do not travel, they just occur. However, the term event is often used metonymically to denote the notification message itself, which may lead to some confusion. This is due to Event-Driven architectures often being design atop message-driven architectures, where such communication pattern requires one of the inputs to be text-only, the message, to differentiate how each communication should be handled. This architectural pattern may be applied by the design and implementation of applications and systems that transmit events among loosely coupled software components and services. An event-driven system typically consists of event emitters (or agents), event consumers (or sinks), and event channels. Emitters have the responsibility to detect, gather, and transfer events. An Event Emitter does not know the consumers of the event, it does not even know if a consumer exists, and in case it exists, it does not know how the event is used or further processed. Sinks have the responsibility of applying a reaction as soon as an event is presented. The reaction might or might not be completely provided by the sink itself. For instance, the sink might just have the responsibility to filter, transform and forward the event to another component or it might provide a self-contained reaction to such event. Event channels are conduits in which events are transmitted from event emitters to event consumers. The knowledge of the correct distribution of events is exclusively present within the event channel. The physical implementation of event channels can be based on traditional components such as message-oriented middleware or point-to-point communication which might require a more appropriate transactional executive framework. Building applications and systems around an event-driven architecture allows these applications and systems to be constructed in a manner that facilitates more responsiveness, because event-driven systems are, by design, more normalized to unpredictable and asynchronous environments. Event-driven architecture can complement service-oriented architecture (SOA) because services can be activated by triggers fired on incoming events. This paradigm is particularly useful whenever the sink does not provide any self-contained executive. SOA 2.0 evolves the implications SOA and EDA architectures provide to a richer, more robust level by leveraging previously unknown causal relationships to form a new event pattern. This new business intelligence pattern triggers further autonomous human or automated processing that adds exponential value to the enterprise by injecting value-added information into the recognized pattern which could not have been achieved previously.

The bottom line is: Javascript isn't built for making a page, it's built for a user-interface. It listens for user interaction and responds accordingly. And when that response happens, it doesn't run any unnecessary code...just the code to respond to the user.

Game Demo: 0:13 TJUG Intro: 2:00 Main presentation: 10:20 http://www.meetup.com/Toronto-Java-Users-Group/events/229066387/ This month, Marius Bogoevici will present Event-driven microservices with Spring Cloud. The future of scalable data proccessing is event-driven microservices! They provide a powerful paradigm that solves issues typically associated with distributed applications such as availability, data consistency, or communication complexity, and allows the creation of sophisticated and extensible data processing pipelines. Building on the ease of development and deployment provided by Spring Boot and the cloud native capabilities of Spring Cloud, the Spring Cloud Stream project provides a simple and powerful framework for creating event-driven microservices. They make it easy to develop data-processing Spring Boot applications that build upon the capabilities of Spring Integration. At a higher level of abstraction, Spring Cloud Data Flow is an integrated orchestration layer that provides a highly productive experience for deploying and managing sophisticated data pipelines consisting of standalone microservices. Streams are defined using a DSL abstraction and can be managed via shell and a web UI. Furthermore, a pluggable runtime SPI allows Spring Cloud Data Flow to coordinate these applications across a variety of distributed runtime platforms such as Apache YARN, Cloud Foundry, Kubernetes, or Apache Mesos. You'll see live deployment demos on different platforms ranging from local cluster to a remote Cloud to show the simplicity of the developer experience. About the speaker: Marius Bogoevici is a software engineer at Pivotal, lead of Spring Cloud Stream, and also working on Spring Cloud Data Flow, Spring XD, and other Spring projects.

In this presentation, I will show you how to combine Apache Ignite with Docker to not only build an event-driven microservice platform but also to make this dynamically re-configurable without any downtime at all. The pre-requisites for the platform are banking grade NFRs such as Exactly Once Processing of requests, High Availability -even in case of data center disasters- and no downtime ever. For this, all containers are linked in one big software-defined network in which the contained services form one big distributed grid, and in which new services register themselves during deploy time and are auto-discovered by the grid to process requests. # Sven Beauprez Sven Beauprez is architect at The Glue, a fintech startup that develops a platform for financial institutions to quickly develop innovative financial services. Sven is an expert enterprise application integration architect with 20 years of experience in different functional domains. He was steering member for 7 years at JavaPolis/Devoxx, and helped it grow to what it is today, and is co-founder and vice-chairman of IoTBE.
