BtrPlace is an open source VM manager that can be specialized on demand by third party developers to integrate new placement constraints. BtrPlace has already been used successfully to address high-availability, security but also energy-efficiency concerns. It has been developped since 2006 in the Mines de Nantes then with the University of Nice-Sophia Antipolis. It is now a part of the OpenCloudware project that aims at building an open platform for the development and the deployment of distributed application on clouds.

Slice t = core.getAssociatedAction(vm).getDemandingSlice();
if (t != null) {runnings.add(t.hoster());}
}
}
core.post(new BoundAllDiff(runnings.toArray(), true));

This talk presents VESPA, an open self-protection architecture and framework for cloud infrastructures that overcomes the previous limitations. Developed in the OpenCloudWare project, VESPA adopts a policy-based management approach, and allows a two-level regulation of security, both within a software layer and across layers. Flexible coordination between self-protection loops allows enforcing a rich spectrum of security strategies such as cross-layer detection and reaction. A multi-plane, extensible architecture also enables simple integration of commodity detection and reaction components. Evaluation results on a VESPA KVM-based implementation show that the design is applicable for effective and yet flexible self-protection of cloud infrastructures.

The XLcloud project strives to establish the demonstration of a High Performance Cloud Computing (HPCC) platform based on OpenStack that is designed to run a representative set of compute intensive workloads. Two Use Cases will be demonstrated during this presentation. First, the interventional radiology use case of the XLCloud project has the goal to show that the XLCLoud platform can be used to leverage an application requiring both interaction and high performance computing. This simulator, developed by CEA and Esprimed, allows medical staff to prepare or replay an intervention in a 3D interactive environment (manipulation of the radiological system, position of people and their protections) while having the benefit of precise estimation of the dose they are exposed to through a 3D monte carlo simulation optimized in order to provide results in interactive time. The second use case will be based on cloud gaming and 3D visualization. XLcloud is a three-year long collaborative project funded by the French FSN (Fonds national pour la Société Numérique) programme.

Code reuse is a major aspect of Open Source and most development languages have developed dependency management systems to enable this practice in a more efficient and secure way. Licencing is another key aspect of Open Source, as it defines it as such. Convergence of those two aspects is then somehow natural and is embodied in the metadata of the package systems. Combined with the general evolution of licencing compliance and its closer integration into development workflows, this angle seems to gain relevance but is still facing limitations, due to (lack of) metadata quality.

When I was a young engineer, I grew listening to an old software engineer that said too often: "You don't know, what you don't know". As years passed, that strange motto started to make more sense for software development. We send zip files or gits with the code of our products to other people in a professional context, too often without really knowing what kind of third-party code and licenses are inside. In this session we go through simple techniques to clearly list the third-party libraries, code snippets and marking your own software as yours in a standardized manner. So that the next time you share code professionally, it is easy for others to understand the applicable licenses and copyrights within.

The OCCIware project aims at managing in a unified manner all layers and domains of the Cloud (XaaS), by building on the Open Cloud Computing (OCCI) standard. OCCIware Metamodel formally specifies the main OCCI concepts. Today a first EMF metamodel is defined that adds to OCCI new concepts such as Extension, Configuration, and EDataType, addressing some limitations of OCCI. This session highlights OCCIware platform two main components: - The OCCIware Studio Factory, allowing to produce visually customizable diagram editors for any Cloud configuration business domain modeled in OCCI using the OCCI Extension Studio, such as the flagship Docker Studio ; - The OCCIware Runtime, based on OW2 erocci project, including the tools for deployment, supervision and administration, and allowing to federate multiple XaaS Cloud runtimes, such as the Roboconf PaaS server and the ActiveEon Cloud Automation multi-IaaS connector. This talk includes a demonstration of the Docker connector and of how to use the OCCIware Cloud Designer to configure a real life Cloud application (a Java API server on top of a MongoDB cluster)'s business, platform and infrastructure layers seamlessly on both VirtualBox and OpenStack infrastructure.

A few years ago, Heartbleed epitomized a massive open source sustainability problem for critical parts of the internet infrastructure. The bug, which affected the popular OpenSSL cryptographic software library, notably compromised the confidentiality of 4.5 million US patient records and cost the industry an estimated $500M. It was soon revealed that the root cause of the issue was that OpenSSL was precariously understaffed. Open source sustainability became a major theme overnight. Stories of maintainer burn-out made the headlines. And tentative solutions started to emerge, most of them donation-based. In this talk we’ll explore a number of existing strategies to fund open source and make it more sustainable, from patronage to dedicated ad networks. And we’ll defend the idea that the best path to open source sustainability is to help companies understand the tangible business value they can get from contributing to open source.

Presentation by Gael Blondelle, Managing Director at Eclipse Foundation. Abstract: In this talk, we will cover two complementary topics: The different Eclipse projects related to Open Source governance, like Eclipse SW360, SW360 Antenna, and Eclipse Steady, as well as the opportunity to leverage SW360 as the core of a larger Open Source governance initiative. The Eclipse IP Process that has been applied to hundreds of Eclipse projects for more than 15 years and is going through a modernization process that involves both simplification from the developer point of view, and openness to new source of trusted data like Clearly Defined.

Open source contribution policies are long, boring, overlooked documents, that generally suck. They're designed to protect the company at all costs. But in the process, end up hurting engineering productivity, and morale. Sometimes they even unknowingly put corporate IP at risk. But that's not inevitable. It's possible to write open source contribution policies that make engineers lives easier, boost morale and productivity, reduce attrition, and attract new talent. And it's possible to do so while reducing the company's IP risk, not increasing it. In this talk, we'll look at the general structure of contribution policies, examples in the wild, and tactics to make them suck less. We'll also look at how to turn these policies into self-service software, preventing the tedious email back and forth between engineering and legal in most cases and making open source contribution a breeze.

Presentation by Jose Manrique, CEO at Bitergia. Abstract: 2020 has started intense for many countries. It's been just a few months, but the things we have lived make us feel like it's been years. Covid-19 pandemic has hit everywhere and forced many people to work from home. If you were lucky enough to be in one of these modern companies that have adopted digital transformation years ago, would that be a problem? Many people have thought it wasn't, but it has really been. And what about the rest of the software developers involved in companies not ready for remote work at all? It's been said that nothing has boosted more companies' digital transformation than covid-19. But, are their managers ready for such change? Managing software development at scale is not an easy task, and this pandemic has disrupted the way projects are being developed in many companies. During this talk, I would like to share lessons learned from open source development at scale that might help companies to adapt to these changes. But more specifically, lessons about how software development analytics help managers to understand collaborative remote work.

Presentation by Boris Baldassari, Consultant, Castalia Solutions. Abstract: While Open Source Software has become mainstream, the understanding of its key principles, from ethics and collaboration to governance and community management, is gaining more interest and attention. There is a comprehensive volume of studies and reports backing up our individual and collective experience, yet we still cannot reliably measure these characteristics, and even less clearly define or assess them. In an attempt to build up confidence and foster maturity in this area, this talk will look at the various existing models and metrics related to OSS compliance and governance, and build upon them to propose methods and tools for their evaluation and analysis. We will discuss the requirements and essential questions to ask, offer guidelines for implementation and suggest efficient ways to present results.

Presentation by Hui Song, Senior Scientist, SINTEF. We would like to share our research journey towards enabling DevOps for IoT applications, and how Open Source makes the journey feasible and fun. DevOps is widely adopted for developing cloud applications, which supports developers in continuously placing software changes directly to production. As companies are including IoT and Edge devices into their IT infrastructures, supporting DevOps for IoT is a must. However, IoT challenges some fundamental assumptions behind DevOps, such as the homogeneous infrastructure and centralized governance, and therefore, breaking-through research is needed. Funded by H2020, 30 people from 12 partners crossing academia and industry gathered to solve these fundamental challenges, which results in full-stack open source tools for automatic deployment, learning-based operation and security monitoring of IoT applications, and risk management of the development process. The tools are evaluated on industrial use cases in intelligent transportation, smart building, and eHealth. The mass open source tools and communities around IoT development provides the sound foundation for this design research and the opportunities for the further exploitation of the results. In particular, we are proud of spinning off a start-up to commercialize the risk management services in the open source + SaaS model.

We propose a walkthrough of current utilization of Open Source Software in capacity planning for the Orange network infrastructure. The objective of our project is to have a platform that helps engineers to carefully plan the resources available to them as well as to correlate different incidents within remote parts of the infrastructure. In order to achieve this we started using Cacti with the Spine collector which worked great, but Orange France is a very large company with many entities, each with its own governance, and so we began to see some limitations. There was a need to centralize some information from different parts in Orange France as well as to integrate the equipment capacity and load values into BigData Orange. In order to achieve this we developed the “Puits de donneés” platform completely based on Open Source Software. The visualization and statistical analysis part is handled by Grafana while the ETL runs on Apache Software Foundation products like NiFi, Zookeeper and Ambari with a storage solution from MariaDB for which we did extensive performance tuning and customization due to the large amounts of data.

Created by Mozilla Research in 2012 and now part of Linux Foundation Europe, the Servo project is an experimental rendering engine written in Rust. It combines memory safety and concurrency to create an independent, modular, and embeddable rendering engine that adheres to web standards. Stewardship of Servo moved from Mozilla Research to the Linux Foundation in 2020, where its mission remains unchanged. After some slow years, in 2023 there has been renewed activity on the project, with a roadmap now focused on improving the engine’s CSS 2 conformance, exploring Android support, and making Servo a practical embeddable rendering engine. In this presentation, Rakhi Sharma reviews the status of the project, our recent developments in 2023, our collaboration with Tauri to make Servo an easy-to-use embeddable rendering engine, and our plans for the future to make Servo an alternative web rendering engine for the embedded devices industry.
