Vert.x introductionGR8Conf

Vert.x is an asynchronous and non-blocking event-driven framework that allows building reactive applications on the JVM. It uses the reactor pattern and handles a large number of concurrent connections through asynchronous I/O without blocking threads. Applications can be written in Java or other JVM languages and deployed as microservices that communicate asynchronously through an event bus. This allows for easy horizontal scalability.

Reactive applications and microservices with Vert.x tool-kitVictor Hugo

This document discusses reactive applications and microservices using the Vert.x toolkit. It defines reactive as responding quickly to stimuli. Reactive systems are responsive, rapid, resilient, and scalable. Microservices break applications into smaller, independent services. Vert.x is a toolkit that can build reactive and microservices applications. It is lightweight, fast, modular, and supports multiple programming languages. Vert.x allows building scalable, high-performance microservices and applications.

Development with Vert.x: an event-driven application framework for the JVMDavid Wu

For a long time JVM developers have been sitting out watching web developers write agile and performant applications with frameworks such as node.js. Fortunately this is no longer the case. Vert.x is a powerful, bleeding edge event-driven application framework for the JVM. It features native support for non-blocking I/O and concurrency. It has a distributed event bus that that allows real-time communication between client and server. In addition to including out-of-the-box modules for easy development, vert.x has a module system that enables code reuse. To be even more cool, vert.x is polyglot, supporting components written in different languages such as Javascript, Ruby, and Python. In this speech I will give an overview of the vert.x framework and some of the caveats that you should be aware of.

OpenNebulaConf 2016 - OpenNebula 5.0 Highlights and Beyond by Ruben S. Monter...OpenNebula Project

OpenNebula 5.0 and 5.2 included improvements to VM recovery and management, storage integration, and drivers. The road to 5.0 focused on compatibility while removing less used components. Sunstone was upgraded. Version 5.4 will focus on simplifying HA deployment and improving usability. vCenter integration allows for datastore and VMDK monitoring and management within OpenNebula. Network and storage roadmaps include automatic network and port group creation and improved storage integration.

An Introduction to the Vert.x frameworkzznate

Vert.x is a new JVM based application framework with an event driven, asynchronous programming model. With APIs available in Java, JavaScript, Ruby, Python and Groovy, developers are given complete freedom to implement their application in the language of their choice. Starting with the core Vert.x concepts, this presentation will walk attendees through the components of a simple vert.x based application. Through this process, attendees will gain an understanding of how Vert.x: - provides for a way to use several different languages in the same application - takes advantage of JVMs excellent multi-core capabilities - uses a module-based framework for packaging and hot-deployment - communicates with other processes via a distributed event bus - exposes an asynchronous programming model with very simple concurrency With this presentation, viewers should gain a deep-enough understanding of Vert.x to be able to evaluate the platform for their own projects.

OpenNebulaConf 2016 - Sunstone integration with FreeIPA using Single Sign by ...OpenNebula Project

FreeIPA is an integrated Identity and Authentication solution for Linux and Unix environments. It provides a centralized authentication and authorization information and it also stores user data information such as user names, groups, hosts and many different objects to manage the security aspects of a network of computers. FreeIPA uses different technologies, but the core of the authentication system is based on MIT Kerberos technology. Thanks to this technology the authentication works on the basis of tickets to allow users or nodes communicating over a non-secure network to prove their identity to get access to different services. In this talk we will show how it is possible to integrate Sunstone authentication with the FreeIPA SSO thanks to the new Sunstone remote authentication plugin provided by OpenNebula. We will describe how to setup Sunstone in an easy way to include Kerberos authentication using Apache and Phusion Passenger module. This configuration approach also changes the security mechanism used by libvirt to establish the connection between hypervisors. We will explain how it is possible, using the host keytabs generated by FreeIPA, to improve the security between the hypervisors when we have to migrate virtual machines in an insecure network.

The document summarizes a disaster recovery solution using OpenNebula and StorPool for a financial institution. The solution involved setting up independent primary and DR sites that could migrate virtual machines between each other. OpenNebula was used for centralized management across sites with StorPool enabling site-to-site transfers of VMs and storage. The solution met the customer's requirements of having completely separate but synced environments across two independent sites with disaster recovery capabilities.

WebAssembly FundamentalsKnoldus Inc.

WebAssembly (Wasm) is a binary instruction format for a stack-based virtual machine that allows deployment of web and server applications. Wasm is not a transpiling target for JavaScript or a replacement for JS, but rather a compilation target for programming languages to enable deployment on the web. The key aspects of Wasm include its stack-based architecture, core data types like integers and floats, control flow constructs, and use of linear memory. WABT is a toolkit that helps manipulate Wasm files, allowing generation of text format (wat) from binary (wasm) and vice versa. Building a Wasm app involves understanding its architecture and using tools like WABT.

Contrail Virtual Execution PlatformNETWAYS

The Contrail Virtual Execution Platform (VEP) allows Cloud administrators to manage data centers and monitor the usage of resources. Users can manage their distributed applications on IaaS Cloud providers under the control of Service Level Agreements (SLA). VEP applications are packaged in the standard OVF format and they are deployed inside Constrained Execution Environments (CEE) derived from the SLA, to support the specification of SLA contracts between users and providers. These CEE environments allow to define constraints concerning virtual hardware performance, localization and affinity allowing the administrator to configure the monitoring system in order to feed external SLA enforcement services. VEP integrates elasticity management capabilities which can be controlled by external SLA enforcement services. A resource allocator service is integrated to dispatch the virtual components on the physical resources of the provider in accordance with the SLA terms. The first version of VEP is currently implemented on OpenNebula. This talk presents the implementation of VEP on OpenNebula and discusses some implementation choices such as the resource allocator.

Real World Enterprise Reactive Programming using Vert.xMariam Hakobyan

Vert.x – The problem of real-time data bindingAlex Derkach

As the popularity of any event-driven application increases, the number of concurrent connections may increase. Applications that employ thread-per-client architecture, frustrate scalability by exhausting a server’s memory with excessive allocations and by exhausting a server’s CPU with excessive context-switching. One of obvious solutions, is exorcising blocking operations from such applications. Vert.x is event driven and non blocking toolkit, which may help you to achive this goal. In this talk, we are going to cover it’s core features and develop a primitive application using WebSockets, RxJava and Vert.x.

Plugging holes — javascript memory leak debuggingMayflower GmbH

This document discusses JavaScript memory leaks and how to debug them. It defines a memory leak as occurring when memory is allocated but not freed by a program. In JavaScript, memory allocation happens through object creation, and garbage collection frees memory. Memory leaks can happen if objects remain referenced and cannot be collected. The document provides tips on how to use Chrome DevTools to analyze heap snapshots and timelines to find leaks, including cases around scopes, properties, closures, events, and detached DOM trees. It suggests strategies like naming functions, tracking individual objects, and handling leaky libraries.

Exceptional Behaviors: How Frequently Are They Tested? (AST 2025)Andre Hora

Exceptions allow developers to handle error cases expected to occur infrequently. Ideally, good test suites should test both normal and exceptional behaviors to catch more bugs and avoid regressions. While current research analyzes exceptions that propagate to tests, it does not explore other exceptions that do not reach the tests. In this paper, we provide an empirical study to explore how frequently exceptional behaviors are tested in real-world systems. We consider both exceptions that propagate to tests and the ones that do not reach the tests. For this purpose, we run an instrumented version of test suites, monitor their execution, and collect information about the exceptions raised at runtime. We analyze the test suites of 25 Python systems, covering 5,372 executed methods, 17.9M calls, and 1.4M raised exceptions. We find that 21.4% of the executed methods do raise exceptions at runtime. In methods that raise exceptions, on the median, 1 in 10 calls exercise exceptional behaviors. Close to 80% of the methods that raise exceptions do so infrequently, but about 20% raise exceptions more frequently. Finally, we provide implications for researchers and practitioners. We suggest developing novel tools to support exercising exceptional behaviors and refactoring expensive try/except blocks. We also call attention to the fact that exception-raising behaviors are not necessarily “abnormal” or rare.
