IoT and OSGi – 20 years in the making

Day 3 - 29th Nov 10:30-11:20 Hall 7 #CM Advanced Novice

For some of us the IoT journey started almost 20 years ago. The term “Internet-of-Things” was not even invented at that time. The world of Java was also much different with just a few big player especially in the Web- and Enterprise-world. Except for Java CLDC enabled mobile phones you rarely found Java in embedded devices. In 1999 the OSGi Alliance started its mission to specify a Java based, modular software architecture for gateways enabling to connect devices in smart homes or offices. The fact that the OSGi framework was Java-based and also an open standard made the adoption difficult in the beginning. Fortunately the world of technology has changed significantly over the years. IoT is mainstream in many domains, others are in a phase of adoption. This presentation will compare the challenges of adopting IoT technologies today vs. 20 years ago as well as our strategy to tackle this challenges. Furthermore this presentation will focus on the role of the OSGi Alliance and Eclipse Foundation as well as how we use these technologies to build an open end-to-end IoT ecosystem. This presentation will conclude with some practical examples where these technologies are already deployed.

Microservices – Just Another Spaghetti Sauce Recipe

Day 1 - 27th Nov 16:20-17:10 Hall 3.1 #J2D Advanced Advanced

Microservices are becoming a de facto standard for software architecture. Business demands to shorten time to market and the constant needs to roll quick updates are primary advocates for microservices.
Microservices showcased they are the appropriate approach to roll fast releases.

However, microservices introduce a lot of complexity that might represent a trap for inexperienced teams, that might easily cause a completely opposite effect. Without appropriate design the code can become even worse that the dreaded monolith and the releases will suffer continuous delays.

Microservices require discipline, experience and broad technical knowledge in order to successfully incorporate them in practice.

In this talk I’m about to present how not to fall in the traps accompanying this approach.

Bug fixing in IoT: Tackling challenges during connected device Integration

Day 1 - 27th Nov 13:30-14:20 Hall 8 #AIST Advanced

Day by day, we are getting more and more excited about the ideas behind the Internet of Things – IoT always brings a picture of a fully-automated surrounding world where connected devices substitute us in many daily activities. It is a fact that our world has already become flooded by smart devices and, as a natural consequence of this fact, many companies are trying to conquer a bigger part of the market, offering the customers their own bespoke IoT platforms that integrate a large number of connected devices produced by renowned manufacturers. However, because there is no such standard accepted for the connected device APIs, as well as the means of device connectivity and communication are almost unlimited, the process of smart device integration turns out to be making the IoT platform providers face a great challenge – the lack of standardization and the various device communication methods, which results in many possibilities for bugs to sneak into the platform. So, the main question stands – how to prevent our smart device integration platform from bugs and make it safe enough?

In order to at least partially answer this outstanding question, being part of the team that is responsible for integrating new devices into a big leading IoT platform for 4 years now myself, I will share my experience how we managed to resolve a lot of issues related to connected device integration and what actions and adaptations our team had to undergo in order to improve the quality of our products. During the session, we are going to have a deeper look over the bugs we fixed in the last year in a statistical manner – what was their type, what components they affected, what time was needed to discover the cause and fix a given defect, what percent of them were real blockers, etc. Further ahead, we will take a look over what structural changes our team had to go through and what mistakes we could have easily avoided in advance. Finally, practical advice is going to be shared in order to clarify how to spot potential bugs and how to improve the quality of the connected device IoT platform we are developing.

Starting with Lisp programming at the University, and then moving into the world of business computing, Alex has worked with a wide variety of technologies. From imperative, object oriented programming, to functional/declarative programming. Alex’s expertise spans developing software solutions for healthcare, financial and e-commerce industry sectors. While still at the University, Alex read a seminal book “Gödel, Escher, Bach: An Eternal Golden Braid” by Douglas Hofstadter and become fascinated by the Artificial Intelligence research. Soon after that came the strong interest in the neural networks research. After spending some time building solutions utilizing the web 2.0 technologies (REST and HATEOAS), Alex got involved in the nascent web 3.0 initiatives (the so-called ‘semantic web’). The web standards fostered by the W3C ‘web app manifest’ ushered the new era of Progressive Web Apps (PWA). In addition to this vast improvement in the web technology, web 3.0 also enables the emergence of Conversational User Interface (CUI). Alex has done extensive work in formulating and implementing conversational interface on the web. He had delivered a talk on that topic at the first European Chatbot conference, held in Vienna, Austria in October 2016 (https://www.youtube.com/watch?v=IzNT1NPlVJU&t=120s).

Because of the explosive growth of the internet, performance requirements for web applications
have grown accordingly. A few years ago the C10K problem was a huge challenge… servers handling
10000 connections at the same time. Nowadays, Twitter gets 300000 requests per second.
Vert.x is a lightweight, asynchronous, event-driven, scalable application framework for reactive
applications on the JVM. It is Open Source and is currently one of the most popular JAVA projects on
Github.
We will together investigate, on the basis of a real architecture, its potential and give you a head
start on this technology.

The secrets of innovation applied to software

Day 2 - 28th Nov 17:20-18:10 Hall 7 #CM Advanced Novice

There is only one path to sustainability : avoid the so-called commodity magnet. New products are -after some time- pulled to this virtual magnet which increases cost, and reduces income for these products. To avoid this, every company has to continuously invest in Innovation to bring new products to the market place.
So, how can one innovate ? What are the secrets to stay ahead of competition ? Why are many companies not able to grow using innovation ? What is the secret to come to the Eureka moment that will push the organization and its employees up the ladder?
