Le feedback rapide offert par le monitoring est un element essentiel des bonnes pratiques de Continuous Delivery. Java dispose dans son ecosysteme d'un composant robuste dedie a cela : JMX.
Cependant, la difficulte de raccordement de JMX a des outils de supervision et de graphe a longtemps ete un frein a son adoption.
Jetez aux orties les solutions bancales a base de logs applicatifs ou d'interface web mal protegees, et venez decouvrir une voie ouverte. Une nouvelle generation d'outils Open Source permet de grapher simplement les metriques de vos applications et de les fournir a un systeme de supervision et d'alerte.
Dans une logique DevOps, nous verrons ensemble comment integrer la dimension Monitoring dans un projet : de la conception des metriques par les developpeurs, a l'integration des besoins des equipes Ops et Q&A, en deploiement traditionnel ou dans le Cloud. JmxTrans, Graphite et Nagios, ce tryptique peut vous faciliter la vie, venez decouvrir comment.

The applications we build have to deal with more and more data and users and having them perform poorly could hurt business pretty bad.
Yet, performance testing is usually not properly dealt with. Too many organizations just throw this brick over the wall to a team that knows nothing of the project, and do so only once the project is almost complete and it's too late to fix it.
While implementing multiple scenarios, we will go through most issues our users encounter and show you how to solve them.

Latest version of the 'Front end microservices' talk
--
Modern frontend has grown in complexity and technologies diversity dramatically last decade. Usual case are apps of >100KLOC with multiple teams shipping code daily. One of the ways to deal with support and further growth of such projects is to apply microservices approach to frontend stack.
There are several solutions in the ecosystem that can enable multiple frameworks run seamlessly within one main uber-SPA. This enables common benefits of microservices approach: freedom of technology choice, separate deployments, faster new developers on-boarding due to reduced complexity of each sub-module, etc. Also this might be a migration path for large frontend monoliths.

Open Source Monitoring for Java with JMX and Graphite (GeeCON 2013)Cyrille Le Clerc
Fast feedback from monitoring is a key of Continuous Delivery. JMX is the right Java API to do so but it unfortunately stayed underused and underappreciated as it was difficult to connect to monitoring and graphing systems.
Throw in the sin bin the poor solutions based on log files and weakly secured web interfaces! A new generation of Open Source tooling makes it easy to graph java application metrics and integrate them to traditional monitoring systems like Nagios.
Following the logic of DevOps, we will look together how best to integrate the monitoring dimension in a project: from design to development, to QA and finally to production on both traditional deployment and in the Cloud.
Come and discover how the JmxTrans-Graphite ticket can make your life easier.
Nodeconf AR 18 Decomposition of the Main thread in Node.js to increase throug...Nikolay Matvienko
I’ll tell about new best practices of large Node.js apps, which allow to increase throughput by 10X times (with demo).
The growth of functionality in Enterprise applications often leads to a decline in throughput. We start with the dispersion of the Main Thread and spread it into a spectrum of operations. We learn which of these operations we can offload from the Main Thread to threads/workers/processes, and how to do that. We select successful ways of parallelization for each type of operation, consider the benefits and limitations. Compare the throughput after the Main Thread decomposition.
The presentation introduces tools and best practices that will help you introduce the SRE principles for PostgreSQL monitoring.
What to expect:
- An introduction to tools and best practices that will help you introduce SRE principles for PostgreSQL monitoring
- We define the four SRE “golden signals,” and explain how they’re used in PostgreSQL
- A relatively-detailed look at our software stack used for monitoring
- A look at high-level differences between traditional monitoring stacks and modern solutions
- An introduction to Prometheus and how it works with PostgreSQL
- Specific examples of Alertmanager rules for alerting
- A comprehensive walkthrough of Grafana dashboards
- Details on our logging pipeline, including our ELK stack and a few other Showmax specialties
This is a talk on how you can monitor your microservices architecture using Prometheus and Grafana. This has easy to execute steps to get a local monitoring stack running on your local machine using docker.

Atlanta JUG - Integrating Spring Batch and Spring IntegrationGunnar Hillert
This talk is for everyone who wants to efficiently use Spring Batch and Spring Integration together. Users of Spring Batch often have the requirements to interact with other systems, to schedule the periodic execution Batch jobs and to monitor the execution of Batch jobs. Conversely, Spring Integration users periodically have Big Data processing requirements, be it for example the handling of large traditional batch files or the execution of Apache Hadoop jobs. For these scenarios, Spring Batch is the ideal solution. This session will introduce Spring Batch Integration, a project that provides support to easily tie Spring Batch and Spring Integration together. We will cover the following scenarios:
Launch Batch Jobs through Spring Integration Messages
Generate Informational Messages
Externalize Batch Process Execution using Spring Integration
Create Big Data Pipelines with Spring Batch and Spring Integration
Troubleshooting Java applications has the reputation of a dark art and is often compared to finding the needle in a haystack. Using tools bundled with the JDK and the OS, a few open source packages and lightweight approaches can help you zero in on a some common scenarios. We will explore working with local and remote JVMs, the myriad of startup flags, analyzing and correlating thread dumps with cpu consumption, system vs application level instrumentation, considerations for multi-tenant JVMs, getting around in an unfamiliar production environment and if we don’t forget, memory games.
If you could use more visibility into your Java application during development and production runs this talk is filled with practical tips, from the high level to the gritty details.

Modernisation of legacy PHP applications using Symfony2 - PHP Northeast Confe...Fabrice Bernhard
PHP and its community has evolved really fast in the last few years to allow for professional architectures and solutions. However, there are thousands of existing PHP applications which have not evolved in the meantime and are now crippled and unmaintainable because of that. These applications represent a real threat to the competitiveness of the business that relies on them.
The best approach in terms of business to solve this problem is progressive rewrite. Symfony2 and its modular architecture make it possible. This talk covers the main technical difficulties of the progressive approach when rewriting legacy PHP applications, and the corresponding solutions, some of which rely on the modularity of Symfony2.

Cache distribué, Network Attached Memory, Data Grid ou Cloud Computing sont des termes très à la mode qui s’inscrivent dans la même tendance.
Nous présenterons pendant cette soirée le chemin qui nous à conduit d’un simple EH Cache à des grilles de centaines de giga octects de données qui s’étalent sur des data center.
CACHES DISTRIBUES
Les Cache Distribués se sont banalisés avec les frameworks Open Source Jboss Cache et EH Cache distribué. Où en sommes nous aujourd’hui ?
- Quels sont les cas d’utilisation d’un cache distribué ? Quels gains en attendre ?
- Comment migrer d’un cache local à un cache distribué ? Nos frameworks sont-ils adaptés à ces caches distribués ?
- Comment fonctionne un cache distribué ?
NETWORK ATTACHED MEMORY
Le concept de Network Attached Memory a décollé dans l’univers Java avec Terracotta et offre à nos applications un espace mémoire encore inimaginable il y a peu. Que se cache-t-il derrière ?
- Quels sont les cas d’utilisation des technologies de Network Attached Memory ?
- Cette mémoire virtuellement infinie n’introduit-elle pas des contraintes ?
- Si la mémoire est partagée, qu’en est-il des traitements ?
- Quelles sont les perspectives des technologies de Network Attached Memory ?
DATA GRID
Le concept de data grid s’est popularisé avec les services Google Big Table ou Amazon S3 mais aussi avec des sites comme eBay qui annoncent des data center gigantesques. Cela va-t-il arriver dans l’informatique classique ?
- Qu’est-ce qu’une grille de donnée ? Comment ça marche ?
- Qui a besoin de Data Grid ? Est-ce réservé aux hyper scalable comme eBay ou Facebook ? Comment faisait-on avant ? En ai-je besoin ?
- Comment structurer une application pour utiliser une grille de données ? Cela la change-t-il la façon de programmer ?
- Map Reduce est-il un pattern utilisable avec une grille de données ? Est-ce le seul ?
- Les grilles de données vont-elles remplacer les bases de données traditionnelles ? Comment peuvent-elles cohabiter ?
DATA GRID, CLOUD ET LES AUTRES
Data Grid, Grid Computing, Cloud Computing et eXtreme Transaction Processing (XTP) sont fréquement associés.
Comment positionner Data Grid par rapport à ces technologies ?
Quels positionnements ont les acteurs de cet univers ? Amazon S3&EC2 ? Coherence ? Gigaspace ? Google App engine & Big Table ? Grid Gain ? Terracotta ? Websphere eXtreme Scale ?

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
