Image SpeakervJUG - A​ ​Craftsman’s​ ​Guide​ ​to​ ​Designing​ ​a​ ​Clean Architecture
2018-04-19
Welcome to the a Virtual Java User Group screening at the Dublin Java User Group ##Marcus Biel # **A​ ​Craftsman’s​ ​Guide​ ​to​ ​Designing​ ​a​ ​Clean Architecture** ##Doors Open 16:30 for 17:00 start. . In 2018, it seems like Microservices are the de facto standard for a system architecture, but do they really live up to the hype? The talk will show you an alternative approach - how we can tame complexity with the help of a clean, monolithic architecture that is modular to the core. Java has been deliberately built from the ground up on a modular basis: Methods, classes, packages. Additionally, the module system was introduced in Java 9. Modularity is based on the fundamental concepts of high cohesion and low coupling. We will look at these concepts, as well as some further measures, in detail. We'll check out what they are, how they are related to one another, and what the best practices are for applying them on all levels of the architecture. The talk will show you how you can apply these basic concepts to develop a clean, monolithic architecture, based on Java 9 modules and the hexagonal architecture pattern. Finally, we'll learn how to achieve a clean microservice architecture based on a modular architecture. About Marcus Biel Marcus is a Clean Code evangelist who has authored a series of video tutorials that focus on teaching others how to create the cleanest and most well-structured code possible. As a conference speaker, he shares his ideas on Java Clean Code development. Marcus is also an author, technical book reviewer and JCP member. In 2017, Marcus was named TOP 13 Java influencer worldwide by jaxenter.com (http://bit.ly/top20JavaInfluencers).

Image SpeakerClass Loaders, Spring and Java with Simon Maple
2018-03-28
Our March event is special! We are hosting Java Champion and JavaOne Rockstar, Simon Maple, Virtual JUG founder and London Java Community co-leader and RebelLabs author. Oh, and Duke’s Choice award winner! ##Simon is presenting.... # **Do You Really Get Class Loaders** ##and # **Productive and Effective Development with Spring and Java EE** ##Doors Open 18:15 (evening session) . Simon is an experienced speaker, having presented at JavaOne, JavaZone, Jfokus, DevoxxUK, DevoxxFR, JavaZone, JMaghreb and many more including many JUG tours. His passion is around user groups and communities. When not traveling, Simon enjoys spending quality time with his family, cooking and eating great food. You can follow him on twitter at [**@sjmaple**](https://twitter.com/sjmaple) and[**@virtualjug**](https://twitter.com/virtualjug) . ##**Do You Really Get Class Loaders** Class loaders are at the core of the Java language. Java EE containers, OSGi, NetBeans modules, Tapestry 5, Grails, and many others use class loaders heavily. Yet if something went wrong, would you know how to solve it? This session takes a tour of the Java class loading mechanism, from both the JVM and developer points of view. It looks at typical class loading problems and how to solve them. ClassNoDefError, IncompatibleClassChangeError, LinkageError, and many others are symptoms of specific things going wrong that you can usually find and fix. For each problem, the presentation goes through a hands-on demo with a corresponding solution. It also takes a look at how and why class loaders leak and how you can remedy that. ##**Productive and Effective Development with Spring and Java EE** This live coding session shines some light on a range of productivity tools that make software development a pleasure rather than a chore. Simon will live-code two applications. The first, a Java EE application with JBoss Forge that uses JPA, Bean Validation, REST, and Angular, is tested with Arquillian from within JBoss Forge. You’ll see how a Java EE microservice can be developed in Forge and run with JBoss Swarm. The second application is developed on Spring Boot, and you’ll see how to develop and run a Spring application with JRebel. You’ll learn how to write code productively with tools designed for developers. . # **The Dublin Java User Group - Sponsor Messages** **Stackand.Co** enrich the professional lives of Java / Scala software professionals - with over 20 years experience in the Irish ICT market, they have helped many great people elevate their careers.

Image SpeakerJava EE 7 Meets Java 8 / Clustering MicroProfile Application using CDI and JCache
2018-01-17
With Java 8 EE taking way longer to release than first expected, it could be some time off before we see Java 9 EE, and since there are many companies in Dublin using Java 7, their engineers will be interested in our first DubJUG event of 2018 which sees Senior Java EE Engineer Roberto Cortez from the Seattle based start-up, Tomitribe, talking about how Java EE 7 meets Java 8, and clustering MicroProfile applications using CDI and JCache. ##Roberto is presenting..... # **Java EE 7 Meets Java 8** ##and # **Cluster your MicroProfile Application using CDI and JCache** ##Doors Open 18:15 (evening session) . . #**About Roberto Cortez** Robert was born in Venezuela, but has spent most of his life in Coimbra, Portugal. With a degree in Informatics Engineering (equivalent to the Bologna Master’s degree) from the Department of Informatics Engineering of the University of Coimbra, he has been working as a Java Developer for 10 years in business areas like Finance, Insurance and Government. Roberto works with many Java based technologies like JavaEE, Spring, Hibernate, GWT, JBoss AS and Maven just to name a few, always relying on IntelliJ IDEA, which he says is his favourite IDE. As a Freelancer / Independent Contractor he travels the world to customers, but also to speak at Java conferences. The direct contact with the Java community made him want to become an active member in the community itself. For that reason, he created the Coimbra Java User Group, and started to contribute to Open Source on Github so he can share some of the knowledge that he has gained over the years. After working for a few major corporations, he became eager to help and grow something from the ground up, so currently works with Seattle based start-up Tomitribe which focus on developing and supporting TomEE, a Java Application server based on Tomcat with Java EE support. Follow Roberto on twitter at [**@radcortez**](https://twitter.com/radcortez) . . # **Java EE 7 Meets Java 8** The last few years have been pretty exciting for Java with new versions of EE and SE platforms. Java EE, introduced a new API to build WebSockets; a new API to parse, process and generate JSON; a new Client API in JAX-RS to invoke REST services, and finally the Batch Processing API to build batch applications. Java SE brought us the long awaited Lambda expressions; the powerful Streams API to perform operations like filtering, mapping or sorting in a very easy and fluent way, and a brand new Date Time API, to deal with the complexities of Timezones and Periods. This session will combine all of these elements together and show you how to easily develop an application using Java SE 8 with Java EE 7, with live coding and samples. . . # **Cluster your MicroProfile Application using CDI and JCache** Microprofile is a new platform definition that optimizes Enterprise Java for a Microservices Architecture and delivers application portability across multiple runtimes. You can use a subset of the Java EE specifications to develop Microprofile applications, with JAX-RS, CDI and JSON-P. Now you need to make it highly available and scalable across a large number of machines. The session will feature a live coding demo where we will turn this Microprofile application, into a fully clustered application using only standard Java API’s. Finally, to show you how light it is, we will run the entire cluster in a set up of Raspberry PI’s. ##**REGISTRATION NOTES** The Dublin Java User Group meetups are designed to enhance the knowledge of developers and technology professionals.

Image SpeakerApache Kafka: A Streaming Data Platform
2017-10-12
We are incredibly privileged to welcome back Tim Berglund, Director of Developer Experience at Confluent, the company that brings you the distributed messaging system and streaming data platform, Apache Kafka. ##Tim is Presenting.... #**Apache Kafka: A Streaming Data Platform** ##and # **Heraclitus, the Metaphysics of Change, and Streaming Data** ##Doors Open 18:15 / Doors Close and Presentation Begins 19:00 Tim can frequently be found at speaking at conferences in the United States and all over the world. He is the co-presenter of various O’Reilly training videos on topics ranging from Git to Distributed Systems, and is the author of Gradle Beyond the Basics. He is also the co-host of the http://devrelrad.io podcast, and lives in Littleton, CO, USA with the wife of his youth and their youngest child; the other two having mostly grown up. You can follow him on twitter at [**@tlberglund**](https://twitter.com/tlberglund). . ##**Apache Kafka: A Streaming Data Platform** When it comes time to choose a distributed messaging system, everyone knows the answer: Apache Kafka. But how about when you’re on the hook to choose a world-class, horizontally scalable stream data processing system? When you need not just publish and subscribe messaging, but also long-term storage, a flexible integration framework, and a means of deploying real-time stream processing applications at scale without having to integrate a number of different pieces of infrastructure yourself? The answer is still Apache Kafka. In this talk, we’ll make a rapid-fire review of the breadth of Kafka as a streaming data platform. We’ll look at its internal architecture, including how it partitions messaging workloads in a fault-tolerant way. We’ll learn how it provides message durability. We’ll look at its approach to pub/sub messaging. We’ll even take a peek at how Kafka Connect provides code-free, scalable, fault-tolerant integration, and how the Streams API provides a complete framework for computation over all the streaming data in your cluster . . **STOP PRESS.....** [**Check out the new Dublin Java User Group Website**](http://dubjug.org) . ##**Heraclitus, the Metaphysics of Change, and Streaming Data** Hailing from the Persian city of Ephesus in around 500 BC, the Greek philosopher Heraclitus is famous for his trenchant analysis of stream processing systems, saying “You never step into the same river twice.” Central to his philosophy was the idea that all things change constantly. His close readers also know him as the Weeping Philosopher—perhaps because dealing with constantly changing data at low latency is actually pretty hard. It doesn’t need to be that way. Almost as famous as Heraclitus is Apache Kafka, the de facto standard open-source distributed stream processing system. Many of us know Kafka’s architectural and pub/sub API particulars as well as we know the philosophy of Heraclitus, but that doesn’t mean we’re equipped to build the kind of real-time streaming data systems that the next generation of business requirements are doing to demand. Like Heraclitus was telling us 2,500 years ago: we need to get on board with streams. This talk is a thorough introduction to the Streams API, an important recent addition to Kafka that lets us build sophisticated stream processing systems that are as scalable and fault-tolerant as Kafka itself, and also happen to align quite well with the microservices sensibilities that are so common in contemporary architectural thinking. We’ll talk about how to deploy Streams applications and look at actual working code that will bring your thinking about streaming data systems from the ancient history of pub/sub paradigms into the current era. . # **The Dublin Java User Group - Sponsor Messages** **Stackand.Co** enrich the professional lives of Java / Scala software professionals - with over 20 years experience in the Irish ICT market, they have helped many great people elevate their careers.

##Presenting # **From Scripts to Serenity - Refactoring test script spaghetti to patterns** ##**Jan Molak / Smartcode** This month, we're welcoming back London-based Jan Molak [**@JanMolak**](https://twitter.com/janmolak) who will show you around the latest release of Serenity/JS, a new and innovative acceptance testing library. In fact, attendees will be the first in the world to hear this new presentation, a walk through of the latest release, followed by a live coding demonstration. He will show you the steps that can be taken to refactor traditional Protractor E2E tests to patterns to make them easier to understand, extend and cheaper to maintain. You'll learn why the Screenplay Pattern is a "logical progression from the Page Objects" and how one line code change can improve the reporting on your existing projects. Even though Serenity/JS builds on Protractor, it can be used to test non-Angular apps too! So if you're using React, Ember or any other framework - come along and see what's new in the world of automation! ##**REGISTRATION** Meetups in TechMeeetp.Space are designed to enhance the technical knowledge of attendees, and due to the overwhelming demand to attend our events they are always full. **PLEASE NOTE - Entry is by registration on this page only** Join the waitlist when tickets are sold out - our sponsor [**Stackand.Co**](http://stackand.co) will be releasing a few more in around a week's time.

# **Building Java Applications with Cassandra** ##AND # **Spark and Cassandra** ## with # **DataStax Global Director Of Training, Tim Berglund** ### (Doors 18:15 and Presentation at 19:00) Running a little later than scheduled, we're incredibly pleased to welcome back Tim Berglund to the Dublin Java User Group's September stage at TechMeetup.Space. **Session 1 – Building Java Applications with Cassandra** So you’re a JVM developer, and you’ve got a big problem to solve. You’ve got way more data than can fit on a single database server, and it’s no passive collection of facts to analyze: this is a transactional application that modifies data frequently and with unforgiving latency SLAs. You need Cassandra. In this talk, we’ll look at how Cassandra operates as a distributed database, and what sorts of challenges it presents to the application developer. Even better, we’ll see what the code actually looks like to perform ordinary database queries against a database like Cassandra. Come to this session to see what a distributed, non-relational database really looks like. **About Tim** Tim is a teacher, author, and technology leader with DataStax, where he serves as the Director of Education. He can frequently be found at speaking at conferences in the United States and all over the world. He is the co-presenter of various O’Reilly training videos on topics ranging from Git to Distributed Systems, and is the author of Gradle Beyond the Basics. He tweets as [**@tlberglund**](http://www.twitter.com/tlberglund) , blogs very occasionally at [**TimBerglund.com**](http://timberglund.com) , and lives in Littleton, CO, USA with the wife of his youth and their youngest child # **A Message from Our Beer and Pizza Sponsor [**Stackand.Co**](http://Stackand.Co)** ## Are you a Java Developer who wants X-Training to Scala? You Bet!! We are now interviewing for a new funded multinational making its place in Ireland. Check the [**'brief' here now**](https://recruit.zohopublic.com/recruit/ViewJob.na?digest=7NZDPrAwelZRR7pgbV1JQv7KazfG.7la5@T8YJItxo0) and then call me, Gerry Nolan, on +353 (0)1 209 1919 for full company details. **Session 2 – Spark and Cassandra** Apache Cassandra is a leading open-source distributed database capable of amazing feats of scale, but its data model requires a bit of planning for it to perform well. Of course, the nature of ad-hoc data exploration and analysis requires that we be able to ask questions we hadn’t planned on asking—and get an answer fast. **Enter Apache Spark.** Spark is a distributed computation framework optimized to work in-memory, and heavily influenced by concepts from functional programming languages. It’s exactly what a Cassandra cluster needs to deliver real-time, ad-hoc querying of operational data at scale. In this talk, we’ll explore Spark and see how it works together with Cassandra to deliver a powerful open-source big data analytic solution . **WHY YOU SHOULD COME TO DUBJUG** We present the content our community truly want and need. The personal insights to cutting edge technology gained at our meetups will not only enhance your knowledge but also lead you to employment opportunities and career satisfaction. This one will be no exception! If you are working in the eCommerce, high availability space, this is a session that will enhance your knowledge of Robustness Testing from one of the most highly respected engineers in Germany. **BEFORE BOOKING** DubJUG events are always over-subscribed and therefore attendance to the events is "Strictly by Registration".

# **Reactive Apps with Akka and AngularJS** ## and # **Discovering how to Decompose a System into Actors** ### (Doors 18:15 and Presentation at 19:00) So we asked you, and you told us. Akka is the flavour of the month and and we're thrilled to be joined by two awesome speakers ready to take to the stage at our meetup on June 30th at TechMeetup.Space. . **Session 1 – Reactive Apps with Akka and AngularJS** **Heiko Seeberger** [**(@hseeberger)**](http://twitter.com/@hseeberger) Akka and AngularJS are a great combination for Reactive Apps. Akka takes care of vertical and horizontal scaling as well as resilience, and with AngularJS it's easy to implement a rich and highly responsive UI talking to an Akka backend via messages. In this session Heiko will build an exemplary Reactive App step by step: starting from the stanalone UI he will first introduce Akka HTTP and Server-Sent Events running on a single node and then move on to an elastic and resilient service built with features like Akka Distributed Data (CRDTs), Akka Cluster Sharding and Akka Persistence.. Heiko Seeberger is a Fellow at Lightbend's German partner, codecentric. With more than 20 years of experience in consulting and software development Heiko is an internationally renowned expert on Scala and Akka. He blogs under [**(heikoseeberger.de)**](http://heikoseeberger.de). # **Interval - Irish Craft Beers and Pizza courtesy of this month's TechMeetup.space Sponsor [**Stackand.Co**](http://Stackand.Co)** . **Session 2 – Discovering how to Decompose a System into Actors** **Iain Hull** [**(@IainHull)**](https://twitter.com/IainHull) On the recommendation of Lightbend's Gary Browne, our second session will be presented by Principle Software Engineer Iain Hull who, incidentally, was introduced and trained in Scala and Akka by Heiko some five years ago. Presently, Iain is a software engineer at Workday, using Scala and Akka to deliver their next generation elastic grid. His twin passions are large scale distributed computing and applying clean code to complex problems. He is interested in good library and api design and how this can improve system design, reliability and reduce friction during development. By attending Iain's presentation you can discover the lessons he learned migrating a multithreaded java server application to Akka. Adopting actors was a journey and, in his own words, some of Iain's early assumptions would create issues later on. He realised he had not fully embraced the let-it-crash philosophy, and didn’t understand how the atomic nature of actors effects data sovereignty or how parts of his application would have to be eventually consistent. In this talk Iain will share his mistakes, how he arrived at those mistakes and how he eventually resolved them. [**Who's Iain?**](https://ie.linkedin.com/in/iainhull) **REASON TO COME** These are two sessions that will enhance your knowledge of Akka from two of the most highly respected engineers known to man. **WHY & WHEN YOU SHOULD REGISTER TO COME TO DUBJUG** We present the content our community truly want and need. The personal insights to cutting edge technology you can gain at our meetups will not only enhance your knowledge, but also lead you to employment opportunities and career progress.

Image SpeakerDublin Java User Group November Meetup - A Paddy Power 3-Way!
2013-11-07
The Dublin Java User Group welcomes Paddy Power's Application Platforms teamsters **John Turner, Noel King** and **Augusto “Gus” Evangelisti** as our guest speakers in November meetup. **Session 1 - Killing off the Dinosaurs** In this double act, John, has been developing software in the financial and betting industry since 1999, and Noel, has led and developed software solutions across financial, travel and gaming industries over the last 8 years start by setting the Jurassic scene. The evolution of software development practices and principals has been accelerated by the “Adapt and Overcome” mantra of a vibrant start-up community. They have rejected rigid heavyweight project management frameworks for lightweight agile alternatives. They have broken down the walls between product management and development, development and operations. And with widespread adoption of Cloud services like RackSpace and AWS the infrastructure landscape is also changing. Despite the obvious benefits resulting from this rapid evolution, there exist a few backwaters that have been left behind. There, dinosaurs still roam the plains in blissful ignorance of what is happening beyond them there hills. Focusing on IaaS and PaaS adoption, John and Noel will discuss some of the dinosaurs they have encountered on their journey and how they are killing them off. John has a huge interest in the changing ways in which software projects are being delivered, leading him to discover, learn and apply the practices and principles fundamental to Agile software development particularly those of Scrum and Lean. Noel too is focussed on driving excellence through team orientated development utilising the best industry standards including software quality assurance, development automation, continuous delivery and leveraging cloud to get your product to market quicker. Between them, their presentation will even get Spielberg will be hopping out of his seat **Session 2 - Get in shape! Yes, I am talking to you, agile engineer.** Following a short break, Gus, who is passionate about software quality, agile and lean practices, and helping agile teams exceed customer expectations while having fun, invites you to discover how to get in the right shape to become the perfect agile engineer. He says if you really want to be a valuable agile engineer then you need to forget about traditional software development phases and responsibilities. Real agile engineers are able to support the team in all its activities. **On the House** Beer and pizza courtesy of [**Paddy Power Jobs**](http://www.workwithpaddy.com/), Coffee by [**DESlock+**](http://tcubedublin.com/tcube-supporters/deslock/) and Buzzing Great WiFi by [**Magnet**](http://tcubedublin.com/tcube-partners/magnet) on the house!

Image SpeakerDublin Java User Group Meetup October 2013
2013-10-15
The Dublin Java User Group is privileged to have Tim Berglund as our guest speaker in October, with beers and pizzas provided by [**Paddy Power Jobs**](http://www.workwithpaddy.com/) Tim has presented at scores of Java conferences worldwide, including here in Ireland, and is now a training evangelist in GitHub. His appearance on Tuesday October 15th follows a full day [**Git & Github Foundation Workshop**](https://tito.io/tcube/github-training) on 14th October. Tim is a full-stack generalist and passionate teacher who loves working with people as much as he loves to code. He believes the best developer is one who is well-informed of specifics and can also make deep connections between software development and the broader world. He has recently been exploring non-relational data stores, why professionalized product management is a global suboptimization, and of course everything related to Git. He does not really believe that it is possible to teach, but rather believes that it is his responsibility to create an environment in which people can learn. **First, Let's Kill All the Product Owners** By now, we are all familiar with the new orthodoxy: the product owner discerns the needs of the customer and feeds them to developers in the form a prioritized backlog. Developers pull work from that backlog, always confident that they're working on the highest-priority feature at the moment, and never having to worry about how those priorities are allocated. This system is simple, efficient, and has helped many teams function better than they used to. Shakespeare wrote, "The first thing we do, let's kill all the lawyers." It might be time to apply this aphorism to product management. A few revolutionary companies are experimenting with the idea that developers should be in charge not only of when they build new features, but what features to build. Rather than mere code technicians following the will of a product and marketplace expert, developers themselves become experts in their product domain, building the tools users need—by conceiving of those tools themselves. Dispensing with the product owner creates an entirely new organizational tenor: one in which everyone is encouraged to master the business's domain, to organize their work in autonomous ways, and to take ownership of the purpose for which the organization exists. For Tim's first presentation of the night, you'd better come ready to hear ground-breaking ideas and engage in group discussion about how these ideas might be put into practice in your workplace. **Introduction to Gradle** Gradle is a compelling new build tool that incorporates the lessons learned from a decade of Ant and Maven. More than just a compromise between declarative and imperative build formats, or between convention and configuration, Gradle is a sophisticated software development platform that simple builds easy and complex, highly automated continuous software delivery pipelines possible to build. Using its extensible APIs and expressive DSL, you're equipped to build your next build. In his second presentation, Tim will give you a fast-paced introduction to this exciting new tool. Tim is author of the Gradle Liquibase Plugin, and co-author of 2011 [**Building and Testing with Gradle**](http://www.amazon.com/Building-Testing-Gradle-Tim-Berglund/dp/144930463X/ref=sr_1_1?s=books&ie=UTF8&qid=1377975058&sr=1-1) with Matthew McCullough, and [**Gradle Beyond the Basics**](http://www.amazon.com/Gradle-Beyond-Basics-Tim-Berglund/dp/1449304672/ref=sr_1_2?s=books&ie=UTF8&qid=1377975058&sr=1-2) a book released only a few weeks ago. Tim is also author of the [**Gradle Liquibase Plugin**](https://github.com/tlberglund/gradle-liquibase-plugin). **On the House** Beer and pizza courtesy of [**Paddy Power Jobs**](http://www.workwithpaddy.com/), Coffee by [**DESlock+**](http://tcubedublin.com/tcube-supporters/deslock/) and Buzzing Great WiFi by [**Magnet**](http://tcubedublin.com/tcube-partners/magnet) on the house!

Image SpeakerDublin Java User Group Meetup August 2013
2013-08-01
In this, the first meetup of the newly formed Dublin Java User Group, Ian Kelly, a highly experienced and passionate Enterprise Consultant presents "Anatomy of an Enterprise Integration Project", followed by Waratek CTO John Matthew Holt who will present "Java Virtualization and Java Virtual Containers". In his presentation, Ian will talk about the technologies and challenges that occur in large scale, multi-platform integration projects. From early discovery phases through to production go-live, Ian discusses in detail the popular technology options available (SOA, ESB, JMS / AMQP, CSV / FTP) and draws on his experiences on their benefits and limitations. Over his 10 years working on a diverse and wide ranging suite of technologies and platforms to help achieve scalable and redundant systems, Ian has managed a number of large scale, multi-tenancy SAP and Oracle integration projects throughout USA, Latin America and Europe for corporations including Home Depot, Volvo and Best Buy. Throughout his presentation, he will talk about his experiences around the complexities, methodologies and politics of being involved in large scale, multi-company projects. Following a short break, John Matthew holt (CTO of Waratek) will walk through how Waratek has introduced virtualisation at the ground level, into the JVM itself and will show how this technology can save any Java developer operating in todays environments huge amounts of time and effort. Are you facing issues with scaling your Java environment and introducing multi-tenancy into your environment? Most solutions to these issues require architectural choices from the start or require extensive updates to your existing code base. What's worse is all of the app server and platform solutions available today behave like an ancient OS, one fault and it all comes crashing down. What if you could get these solutions built in to your JVM, requiring no code changes what so ever? Furthermore what if the solution provided the isolation desperately missing from the JEE environment and other platforms? This would free you to concentrate on the code that matters, the business logic.

Image SpeakerCloudStack Clients and Wrappers
2013-07-10
Paddy Power are proud to announce EMEA Open Source Cloud Computing evangelist for Citrix, Sebastien Goasguen, will make a presentation at TCube on 10th July, and every attendee will receive a pair of Paddy Power pants as modeled by Arsenal hitman Nicklas Bendtner in his recent outing as striker for Denmark's clash with Portugal. As well as his daytime work in Citrix, Sebastien is also an Apache committer on Apache CloudStack. He is in Dublin supervising Paddy Power's interns on the Google Summer of Code project. Join Sebastien for his acclaimed presentation entitled "CloudStack Clients and Wrappers, survey and demos." CloudStack comes with a very rich API. Most users directly access the API in the language of their choice using the approximately 15 clients available on github. In this talk Sebastien will review the basics of the CloudStack API and go through a few clients: CloudMonkey, Libcloud, Boto, jclouds-cli and then dive into more high level wrappers like knife-cloudstack which in addition to provision virtual machine management adds a layer of configuration by integrating Chef. Sebastien will also introduce Apache Whirr and jclouds based tool to deploy big data clusters on cloud providers and see how it interacts with CloudStack. Attendees will come out with a clear view of the various clients available, the limitations and key strengths. To round the night off, Ian Duffy will talk about his experience to date with the Google of Summer Code Project and how he has been getting on with the Cloudstack Community. Along with his project titled "LDAP user provisioning". Did we mention Pizza and Beer? Of course we didn't! Who cares when you can get a pair of these striking Paddy Power Y-Fronts? Doors Open 6.30pm Pizza and beer served too ;) Photo Courtesy of http://www.thesun.co.uk/sol/homepage/sport/football/ [**SORRY EVENT FINISHED - CLICK HERE TO VIEW UPCOMING JAVA EVENTS**](https://ti.to/dublin-java-user-group/)
