Image SpeakerServerless Deep Dive with Bert Ertman
2018-04-24
Our April event welcomes fellow, and Director of Technology Outreach at Luminis, Bert Ertman. A frequent speaker on Java, Cloud, and software architecture all over the world, Bert is a book author, and serial conference organizer. Bert Ertman was awarded the coveted title of Java Champion in 2008, and is a JavaOne RockStar speaker and Duke’s Choice award winner. ##Bert is presenting.... # **Serverless Deep Dive** ##Doors Open 18:15 (evening session) . ##**Serverless Deep Dive** No server can be more easily managed than no server. Therefore: meet Serverless, a paradigm that truly approaches the Pay-as-You-Go philosophy once promised by the Cloud. In this deep dive Bert will explore the Serverless paradigm by diving into the Serverless manifesto first and by explaining the differences between Serverless, FaaS, and PaaS., and then looking at the different Cloud vendors and what they have to offer in the Serverless space. After the theoretical first part, Bert will start developing some functions with AWS Lambda, since it is, he says, by far the easiest entry point into the world of Serverless. Then he will take a step back to discuss how existing architectures (ie modern web applications) will be impacted. Where does it actually make sense to use this kind of technology and where doesn't it. Finally Bert will end with a number of drawbacks to consider and to make it a balanced story of both pros and cons. Besides AWS Lambda, he'll look at alternatives like Apache OpenWhisk and recently announced Project Fn as well. This talk thoroughly explores Serverless, its impact on existing architectures, and assesses it's usability for Mobile Back-ends as a Service (MBaaS), Functions-as-a-Service (FaaS) and for Microservices hosted in the cloud. Internet connectivity permitting, there will be lots of demos too..

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). On his website Clean Code Academy, he offers comprehensive online training for Java Clean Coding (https://join.cleancodeacademy.com/).
