In this session we’ll highlight Microsoft’s open source offerings for Azure, and talk about how Java developers could benefit from using Azure services in their applications. The focus will be on real-world examples using Microsoft’s open source SDKs on GitHub and tools available for non-Microsoft developers, with a drill-down into our Java offerings and how they can enhance Java applications. We also want to gather feedback from attendees on some exciting new offerings designed to make it easier to deliver Java in the cloud.

In an era of microservices and cloud computing, Micronaut incorporates support for cloud-friendly reliability patterns - from load balancing and circuit breakers to shared configuration and service discovery - and makes these features available and easily configurable from within your application. From the ground up, Micronaut applications are "natively" cloud-native.
The Micronaut framework values at the core, enabling code simplicity and developer productivity. Micronaut offers many additional features for a new class of applications (e.g., microservices, serverless deployments, etc.) that may not be well-suited for monoliths.
With Java 9, modularity comes to your doorstep (whether you ordered it or not). This isn't your average language feature: making the most out of it may involve rewiring your brain. In this session we explore the benefits of a modular codebase using Java 9 modules. Because who doesn’t like more reliable and secure applications, meanwhile killing the dreaded classpath?
After reviewing the basic concepts of modules, we'll explore modularity patterns that enhance your design and development skills. We all have existing software, so migration of codebases to a modular world is an important topic as well. Automatic modules and other new concepts are added to your toolbox to this end.
Want examples? We've got plenty in this practical and code-driven talk. Even if you intend to use Java 9 without modules, this talk helps you prevent common issues. You'll be ready for Java 9 before you know it.
Both speakers are currently writing “Java 9 Modularity” for O’Reilly, expected early 2017. They have extensive experience under the belt already with the Java 9 Jigsaw early access builds.

Performance of Microservice frameworks on different JVMsMaarten Smeets
A lot is happening in world of JVMs lately. Oracle changed its support policy roadmap for the Oracle JDK. GraalVM has been open sourced. AdoptOpenJDK provides binaries and is supported by (among others) Azul Systems, IBM and Microsoft. Large software vendors provide their own supported OpenJDK distributions such as Amazon (Coretto), RedHat and SAP. Next to OpenJDK there are also different JVM implementations such as Eclipse OpenJ9, Azul Systems Zing and GraalVM (which allows creation of native images). Other variables include different versions of the JDK used and whether you are running the JDK directly on the OS or within a container. Next to that, JVMs support different garbage collection algorithms which influence your application behavior. There are many options for running your Java application and choosing the right ones matters! Performance is often an important factor to take into consideration when choosing your JVM. How do the different JVMs compare with respect to performance when running different Microservice implementations? Does a specific framework provide best performance on a specific JVM implementation? I've performed elaborate measures of (among other things) start-up times, response times, CPU usage, memory usage, garbage collection behavior for these different JVMs with several different frameworks such as Reactive Spring Boot, regular Spring Boot, MicroProfile, Quarkus, Vert.x, Akka. During this presentation I will describe the test setup used and will show you some remarkable differences between the different JVM implementations and Microservice frameworks. Also differences between running a JAR or a native image are shown and the effects of running inside a container. This will help choosing the JVM with the right characteristics for your specific use-case!
Simple tweaks to get the most out of your jvmJamie Coleman
Many developers don’t think about the JVM level when creating applications. It is something that just simply works. Now more applications are becoming cloud-native and we have JVM’s running in every microservice container, each performance gain can have massive benefits when scaled up. Some tweaks are very easy to implement and can have huge impacts on start-up time and performance of your applications. This talk will go through all the different JVM options and give you some easy and simple advice on how to get the most out of your JVM to save not only money but also energy on the cloud.
The new GraalVM from Oracle supports multiple language including JavaScript, Python, Ruby, R, C++ as well as Java and other JVM languages. This opens up interesting possibilities for polygot enterprise applications. Now you can use a Node library in a Java application or call an R statistical function from an EJB. Previously, this type of integration was extremely challenging. This session will provide recipes to get up and running along with best practices and some cool demos.

By the time we’re finished, you’ll have a good understanding of the features of the framework and be ready to start building and deploying your own apps with Micronaut. Buckle up and start the countdown!

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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

» Definition: a technique used by the GWT compiler to
create and select a specific implementation of a class
based on a set of parameters.
» GWT produces a different application permutations for
each browser environment.
Only one of these permutations is downloaded and executed
by the browser.
Permutations can be created for each Locale.
Additional custom parameters can be configured.
Deferred Binding
DOMImpl impl = GWT.create(DOMImpl.class);

» Branching is done in compile time rather than runtime.
No runtime penalty for lookup.
» Download and evaluate only the minimum needed
code.
Reduce download size.
Reduce execution time.
» Saves development time by automatically generating
code to implement an interface or create a proxy class.

» Relies entirely on JavaScript.
Cannot work if JavaScript is disabled.
Accessibility issues (especially with older readers etc).
Limited reflection.
Limited SEO (search engine optimization).
» HTML Markup is harder to tweak.
» Longer design-refresh development cycles compared to
pure HMTL/CSS/JavaScript development.
» Almost impossible to debug production client-side code.

» When using RPC, model passed to the client must be
“hand-picked”.
i.e when working with JPA/Hibernate.
Might need to create TOs.
» Relatively slow bootstrap on page load compared to
plain HTML/CSS pages.
Which is eventually faster, if application only loads once.
But might be annoying if application is reloaded on every page
change.
