Kafka for JUnit enables developers to start and stop a complete Kafka cluster comprised of Kafka brokers and distributed Kafka Connect workers from within a JUnit test. It also provides a rich set of convenient accessors to interact with such an embedded or external Kafka cluster in a lean and non-obtrusive way. Kafka for JUnit can be used to both whitebox-test individual Kafka-based components of your application or to blackbox-test applications that offer an incoming and/or outgoing Kafka-based interface. This presentation gives a brief introduction into Kafka for JUnit, discussing its design principles and code examples to get developers quickly up to speed using the library.

RabbitMQ is an open-source message broker software written in Erlang that implements the AMQP protocol. It supports multiple messaging protocols and follows FIFO methods. RabbitMQ is commonly used to build distributed systems that communicate via asynchronous messaging. It provides high availability, scalability, reliability, and security for enterprise systems and has good performance. RabbitMQ acts as a message broker that accepts messages from producers and forwards them to queues. It gives applications a common platform to send and receive messages.

gRPC can help minimize the barrier of cross-system communication by providing language-agnostic API definitions, backward and forward compatible versioning with protocol buffers, and pluggable load balancing and tracing. You will see how to quickly get up and running with the gRPC framework using Node.js from creating a protocol definition, creating meaningful health checks, and securing the endpoint. Additionally, this session will go over best practices and how to take full advantage of what gRPC has to offer.

1. The document discusses application development challenges for the Internet of Things (IoT), including heterogeneity of devices, large scale, lack of separation of concerns, and life-cycle issues. 2. It proposes a conceptual model that classifies IoT concepts and relates development concerns to promote reusability. 3. A multi-stage model-driven approach is presented using a set of modeling languages to abstract heterogeneity, scale, and support automation across development stages.

1) Event-driven microservices involve microservices communicating primarily through events published to an event backbone. This loosely couples microservices and allows for eventual data consistency. 2) Apache Kafka is an open-source streaming platform that can be used to build an event backbone, allowing microservices to reliably publish and subscribe to events. It supports streaming, storage, and processing of event data. 3) Common patterns for event-driven microservices include database per service for independent data ownership, sagas for coordinated multi-step processes, event sourcing to capture all state changes, and CQRS to separate reads from writes.

This document provides an overview of HTML5 WebSocket technology. It discusses limitations of traditional HTTP and how WebSocket enables full-duplex communication by reducing overhead and latency compared to alternative techniques like polling. The WebSocket API and protocol are introduced, along with browser support and server library options. Key benefits of WebSocket include unlimited connections per server, very small overhead, and true real-time bidirectional communication across the web.

High level overview of CoAP or Constrained Application Protocol. CoAP is a HTTP like protocol suitable for constrained environment like IoT. CoAP uses HTTP like request response model, status code etc.

Domain Driven Design provides not only the strategic guidelines for decomposing a large system into microservices, but also offers the main tactical pattern that helps in decoupling microservices. The presentation will focus on the way domain events could be implemented using Kafka and the trade-offs between consistency and availability that are supported by Kafka. https://youtu.be/P6IaxNcn-Ag?t=1466

Scale changes everything. What once was quite adequate for enterprise messaging can't scale to support "Internet of Things". We need new protocols, patterns and architectures to support this new world. This session will start with basic introduction to the concept of Internet of Things. Next it will discuss general technical challenges involved with the concept and explain why it is becoming mainstream now. Now we’re ready to start talking about solutions. We will introduce some messaging patterns (like telemetry and command/control) and protocols (such as MQTT and AMQP) used in these scenarios. Finally we will see how Apache ActiveMQ is gearing up for this race. We will show tips for horizontal and vertical scaling of the broker, related projects that can help with deployments and what the future development road map looks like. Martyn Taylor is a senior software engineer at Red Hat, with over 7 years’ experience working on cloud, middleware and messaging software. Martyn currently works on the Apache ActiveMQ suite of projects.

MongoDB scales data horizontally using a technique called sharding where the data is partitioned across independent database nodes called shards in a way that distributes the data and load. The document discusses how MongoDB automatically partitions and distributes data and queries across shards as the data size and throughput increase, and how it considers factors like cardinality, write distribution and reliability when selecting a shard key to optimize this distribution. It provides an example of how assetId could be used as a shard key for IoT sensor data to partition the data by asset across shards.

Connected world solutions combine sensors and technologies to enable objects and infrastructure to interact over networks through monitoring, analytics and control.

Responsive Design's is a way of making a single website that works well on mobile, tablet, and desktop browsers. Back in 2010 Ethan Marcotte, first coined the term "responsive design" and described it as having 3 components: Flexible Images Fluid Grids CSS Media Queries Well it seems Ethan let quite a few cats of out bag with this one, and we've been trying to herd those cats ever since. What started as exclusively a front-end web design technique has expanded to include a whole new range of both front-end and server-side programming techniques. The real challenge came when we also suddenly discovered that tried and true practices for project management, and creative concept development all started to fall apart. It’s not practical to create photoshop mockups of ever page in a site at every device size - There’s simply too many variables to account for in graphic design software. Responsive Design requires a new process for creating websites, and new ways of interacting with teams and clients. This presentation will outline a birds-eye-view of Responsive Techniques, Strategies, Tools, and Gotchas of RWD. It will focus on some of the new workflow techniques needed and cover some suggestions for where to go to learn more. Slide Summary 1-25: History of Responsive Design 26-50: Coding Basics (Developer Focused) 51-57: Progressive Enhancement 58-70: Mobile First 71-93: Responsive Workflows 96-99: Selling Responsive Design

The document discusses M2M protocol interoperability using an IoT Toolkit and Smart Object API. The IoT Toolkit aims to provide interoperability across any application, connected object, and M2M protocol through a simple API and data/information models. The Smart Object API defines a virtual representation of a physical smart object using an object model, REST API, data models, and event model to link data with actions and enable pub-sub event handling.

The document describes an IoT Toolkit and Smart Object API that aims to enable interoperability between IoT applications, connected objects, and machine-to-machine protocols. The API defines a virtual representation of physical smart objects using an object model, REST API, data models, and event model. It allows applications to connect to any thing via any M2M protocol by abstracting the underlying protocols and providing a common interface through the Smart Object API.

Different messaging and data sharing standards, such as AMQP, CoAP, DDS, MQTT, and REST have been proposed as candidate for addressing the data sharing challenges of the Internet of Things (IoT) and the Industrial Internet (I2). In technical forums and social media there is no lack of passionate discussions that praise the merits of one standard over the other. Yet, to date, there are little or perhaps no analysis that look at the details of the different standards and perform an in depth, qualitative, analytic and empirical evaluation. This presentation, will (1) introduce the key standards that are being proposed for the Internet of Things and the Industrial Internet, such as AMQP, CoAP, DDS, MQTT and REST, (2) present a qualitative comparison that highlights the different features provided by the various standards, (3) present an analytic comparison looking at the efficiency and scalability of the various protocols and (3) report the results of an empirical evaluation comparing the actual performances of the various standards.
