OSGi Community Event 2018 Presentation by Jurgen Albert (Data In Motion Consulting GmbH) Abstract: OSGi is often conceived as a tool to write efficient Java Applications for resource limited Devices or If resources are a real issue in complex applications. On the other hand Microservices became the buzzword of the cloud and is often implemented using Spring or other Programming languages. OSGi carries the concept of microservices in its core and is therefore much better suited to the task then most other approaches. This talk will show you how a service can be built with a real-worldish use case, leveraging the power of OSGi R7. It will show the combined usage of PushsStreams, the JaxRS Whiteboard, the configurator, remote deployment and a lot of the other cool things OSGi has to offer.

OSGi Community Event 2018 Presentation by David Bosschaert (Adobe) Abstract: OSGi lends itself well to develop extensible applications assembled from reusable modules, where a set of bundles together with a set of configurations deployed to a provisioned OSGi framework is the application. While this works very well for the originally intended use-cases, maintaining and building large applications developed by multiple teams often requires to assemble multiple larger components for which there is limited support in OSGi as of today. This is especially true in cases where multiple groups of bundles, configuration, metadata, and other artifacts need to be combined. In this talk we will introduce you to OSGi RFP-188, named OSGi Features, which defines the requirements on providing a solution. We'll establish a shared understanding of the problem space and how it relates to already available mechanisms in OSGi (like e.g. subsystems, deploymentadmin, startlevels, etc.) and will subsequently, review it in the context of some of the current (open source) solutions like Apache Karaf Features and Apache Sling Features and Bnd.

OSGi Community Event 2018 Presentation by Amit Kumar Mondal (Deutsche Telekom AG) & Jochen Hiller (Deutsche Telekom AG) Abstract: QIVICON is an Eclipse SmartHome based solution from Deutsche Telekom AG. It utilises OSGi to provide a modular Java runtime. Since the beginning, QIVICON leveraged Eclipse PDE with Maven & Eclipse Tycho as its build technology but over the time, the complexity increased. It became hard to get an overview and manage the runtime and build dependencies. Especially maintaining target configurations for IDE and CI/CD build, having different embedded gateways for installation increased complexity significantly. Bndtools is the 'swiss army knife' in the context of OSGi development since it takes the nitty-gritty pains and loads off the developer's chest. And that's why we decided to avail the benefits of Bndtools. But, many other OSGi-based projects still cannot avail the benefits as they are very tightly coupled with Eclipse PDE. Want to make a switch from your existing PDE source base to Bndtools? This talk would give you an overview to proceed towards this. We would like to further demonstrate in this talk how to set up a Bndtools workspace from an existing PDE workspace, convert all current projects to Bnd projects and embrace the OSGi-way of developing bundles. Since QIVICON containing more than 350 projects utilised this solution to move to a higher modularity maturity level, this talk would, therefore, outline the pros, cons and the learnings using Bndtools in such a big OSGi project for embedded development.

OSGi Community Event 2018 Presentation by Jörn Tümmler (SMA Solar Technology) Abstract: SMA is a leading global specialist in photovoltaic system technology with more than 3,000 SMA employees in 20 countries. In 2015 SMA decided to develop the ennexOS platform - a cross-sector platform for holistic, intelligent energy management. An important part of this platform is the data-manager - an IoT gateway that acquires information from various energy generators, storages and loads and performs commissioning and management tasks. This new generation of data-managers demanded for new approaches in software-architecture to: run on a broad range of hardware platforms, and be extendible e.g. to support different protocols for easy integration, and to enable a broad range of applications in the energy-management field that may be customized by apps installed during runtime After an exhaustive investigation on existing solutions, OSGi was chosen as the key technology for this new generation of devices - a quite challenging decision, because at this point there was only limited experience in Java and OSGi development in the company. This talk will present the key factors that lead to this decision, how we very carefully build up Java and OSGi knowledge, and started with an initial design. OSGi enRoute and the support of OSGi experts helped us to accelerate our development and become familiar with OSGi - although we also had times when we were struggling because of the new technology. The talk will demonstrate what we have reached until now and we will tell you if OSGi has kept it's promise ...

OSGi Community Event 2018 Presentation by Lukasz Dywicki (Code-House) Abstract: During this short presentation I will revisit existing mechanisms and approach towards OSGi and JEE development. I will show how many manual steps can be avoided and how to maintain project in effective manner. I will try to find a balance between execution environment requirements and programmer happines at same time. I believe that OSGi and Eclipse ecosystem experience troubles gaining people from outside for few reasons. Beside overall impression of OSGi complexity there is equally old and invalid complain about quaility of developer tooling. Since invention of BND development experience can be really pleasant and independent of text editor/IDE preferences. Sadly lots of people still rely on former experiences spreading black/bad PR. I would like to clarify their point. After this presentation attendees will learn: How to use Maven to build OSGi projects (without Tycho). How to automate manual tasks. How to build custom software distributions with Maven artifacts and run it with Apache Karaf. That OSGi development doesn't differ much from regular day-to-day usage of application servers or microservice runtimes. This talk is intended for people who know basics of OSGi as it will show few basic technics towards better developer productivity.

OSGi Community Event 2018 Presentation by Christian Schneider (Adobe) Abstract: We will look at common cloud and design patterns and see how the special properties of the OSGi environment allows us to rethink these patterns. The talk shows some well known patterns like the service registry and the whiteboard but also some unique patterns like out of band circuit breaker or graceful degregation. The patterns are shown with some examples using declarative services(DS). So some basic OSGi and DS knowledge is of advantage but not required. For OSGi beginners the well established OSGi patterns will help getting started the right way. Experienced OSGi developers will find some new patterns to think about. Cloud or enterprise developers will get a new approach to some patterns they are used to which hopefully inspires them to take another look at the current state of OSGi.

OSGi Community Event 2018 Presentation by BJ Hargrave (IBM) Abstract: OSGi Compendium R7 provides a major update to the OSGi LogService specification. A new logging API is added which supports logging levels and dynamic logging administration. A new Push Stream-based means of receiving log entries is also added. But it is quite often the case you need to use other code such as open source projects which are using slf4j for their logging API. This session will explore the new OSGi LogService changes and how you can integrate code using both slf4j logging and OSGi LogService logging.

OSGi Community Event 2018 Presentation by Tim Verbelen (imec) Abstract: Nowadays AI is reaching new heights on the hype cycle, especially due to recent advances in deep learning techniques. A lot of deep learning frameworks exist for creating and training deep neural networks, the most popular ones being PyTorch and TensorFlow. However, how to integrate, deploy and manage these neural networks in complex software systems is often overlooked. In this talk we show how OSGi can be used as a modular runtime for deep learning models. We embed those models inside OSGi bundles, and use the extender pattern to make these available as OSGi services. You can then use your favorite OSGi specs such as DS and PushStreams to integrate these into your application.

OSGi Community Event 2018 Presentation by Tony Walsh (ESA) & Hristo Indzhov (Telespazio Vega) Abstract: The European Space Operations Centre (ESOC) is the main operations center for the European Space Agency (ESA), operating a number of earth observation and scientific missions. Monitoring and control functions needed by spacecraft operators are provided by software systems which are reused across missions, but tailored and extended for mission specific needs. The current generation of monitoring and control systems are becoming obsolete and a European wide initiative called the European Ground Systems Common Core (EGS-CC) (http://www.egscc.esa.int) has been started to develop the next generation. This talk will explain why OSGi was chosen and how it is used in the development of next generation of monitoring and control software. It will describe how OSGi provides the necessary framework that enables the software to be extended for the different space systems it is expected to support. The overall software architecture will be discussed, some of the challenges faced and the benefits gained by using OSGi. The first target mission for the system is JUICE (http://sci.esa.int/juice) which will explore the moons of Jupiter and which is scheduled for launch in 2022.

OSGi Community Event 2018 Presentation by Bruce Jackson (Myriad) Abstract: Node-RED is often used as a protyping tool for IoT systems. However, there are also a large number of OSGi components that have already been built to interface to devices, sensors and systems. In this talk I will show how two completely different runtime environments (OSGi and Node-RED) can be combined into a single platform for prototyping (and more) combining the strengths of both languages and systems. Being able to quickly and simply prototype IoT application is extremely useful, and to this end many people have adopted Node-Red, a Node.js based runtime with extensive support for plugins to interface to various IoT hardware and protocols. However, this requires these services/protocols to be developed in Javascript, and there is already a significant body of code developed in Java/OSGi that it would be desirable to re-use. The talk will explain how it is possible to: Create and manage a Node-Red runtime from within an OSGi bundle  Share OSGi components and object into the Node-Red runtime  Interact and build Node-Red flows that exchange data and call methods between Node.js and OSGi This is obviously useful for the original purpose: prototyping IoT systems, but also demonstrates some interesting techniques for bridging between different languages and runtimes.

With OSGi there are several ways to accomplish this, as there are different specifications to achieve this. In this talk we will look at some of these specifications to show what options there are and which might fit your requirements. Starting from an architecture that makes use of the HTTP Whiteboard pattern, over Remote Services to finally showing the usage of the JAX-RS Whiteboard specification introduced with R7. We will show the general usage of these specifications and explaining the advantages and disadvantages of each solution.

OSGi Community Event 2018 Presentation by Lisa Nafeie (DLR) Abstract: Classic software architecture visualizations such as UML diagrams are widely used in practice but are not always the best solution, for example to get an high level overview of large component-based software systems. In this talk, we show other suitable technologies for software visualization to understand complex software architectures. Especially, we show how to visualize OSGi based software architectures in Virtual Reality (VR) using VR headsets. We address the question, how software visualizing can help during the development process and what are the resulting benefits for developers and software testers. We focus on four aspects: Development, evaluation, quality assurance, and visualization technology. We demonstrate software visualization using the software ”IslandViz”, which visualizes OSGi based software systems using an island metaphor, where islands on a virtual water level represents OSGi bundles, regions on the islands represents packages, and buildings represents classes. We describe how to get all relevant data for the visualization by repository mining on the whole source tree and data mining on source code level. We store all data in a graph database for further analysis and visualization. Through software visualization we were able to answer many important questions, which have already taken a lot of time in development and test-phases. In addition, it’s very important to make the software architecture tangible, which makes it easier way to talk about technical problems in teams formed by people with different knowledge, communications skills, and backgrounds.

OSGi Community Event 2018 Presentation by Tim Ward (Paremus) Abstract: The model of centralized cloud compute is changing. As large-scale IoT deployments have started to become real organizations are realizing that a single central cloud can’t cope with the data security, data volumes, latency or robustness that they need for their businesses. Centralizing in a single cloud also offers a huge operational risk – if the cloud fails, their business must continue! This talk will introduce BRAIN-IoT, an EU Horizon 2020 funded project. BRAIN-IoT uses the latest OSGi R7 specifications to create an adaptive modular “Fog” environment with decentralized data processing and decision making. We’ll review the current design decisions made by the BRAIN-IoT team, including the issues concerning generic Edge Device discovery & integration, and see how they can be applied across different IoT use cases, including Smart Utilities and Industry 4.0 Factories of the Future.

OSGi Community Event 2018 Presentation by Alasdair Nottingham (IBM). Abstract: The OSGi framework, and the service specifications, is a powerful and simple way to build modular software. However writing modular software is hard and even a simple framework doesn’t necessarily make things easy, especially when you are writing an application server consisting of over 100 discrete features. When that application server needs to dynamically respond to configuration changes, provisioning (or deprovisioning) features as required. Even worse when it has to support Java EE applications which are written with a totally different modularity (cough-cough) model. Open Liberty was designed from the ground up to use OSGi as it’s core modularity framework, making extensive use of declarative services, metatype, and subsystems. We did a lot right, we made mistakes, some we fixed some not so much, we fixed a lot of bugs including a number in Felix SCR. Come along to hear a lessons learned about how we used OSGi to build the most flexible application runtime for building web and cloud applications.

OSGi Community Event 2017 Presentation by Emanoel Xavier (Intel) and Tim Ward (Paremus) Open Security Controller (OSC) aims to increase the security of workloads running in cloud and data centers by orchestrating security virtual network functions (VNFs). To achieve that, one of the main design goals of OSC is to allow vendor customization while keeping its core code neutral. Additionally, as an open source project, another import design principal for OSC is code habitability. Evolving from a legacy monolithic application to a modularized one through OSGi has enabled OSC to implement these goals. Bringing together a diverse group of security services and software defined network (SDN) providers was key to building the OSC community. This was possible due to the OSC plugin model using OSGi which allows specific vendors to integrate OSC with their existing solutions with minimum effort. Beyond its plugin model OSC also makes use of OSGi in its core components. This enables better extensibility, testability and overall maintainability of its code base. These aspects are key to OSC as it relates to the new and dynamic areas of SDN and security VNFs in cloud and data center environments and it must be able to easily adapt to the constantly changing requirements and technologies pertaining these fields. In this talk we will explore the journey for turning OSC into a modularized application using OSGi, highlighting some of the achieved results, key learned lessons and the next steps for this work. https://www.opensecuritycontroller.org/

OSGi Community Event 2017 Presentation by Emily Jiang [IBM] Eclipse MicroProfile Config defines a Java programming model for microservices. It offers the capability of configuring microservices without repacking the microservices; microservices reacting differently based on the deployment environment; dynamic configuration feeding into the microservices without restarting the microservices. OSGi Config Admin exists for many years and offers an efficient configuration model to OSGi applications. MicroPorfile Config can work well in OSGi applications. It doesn't contradict but instead compliments Config Admin. Come to this session to find out the common and different features between the two technologies, as well as the possibility of integrating Eclipse MicroProfile Config to OSGi applications.
