Is Serverless just running functions in a cloud? It’s more than that! Serverless computing refers to the concept of building and running applications that do not require server management. It describes a deployment model where applications, bundled as one or more functions, are uploaded to a platform and then executed, scaled, and billed in response to the exact demand needed at the moment. During the talk I’ll show how to use Knative both on Kubernetes and on OpenShift platform. Hopefully we will see why your organization should consider using Knative as one of its primary deployments models on hybrid cloud world.

Nico will show how to hijack a Kubernetes cluster based on common attack vectors. You'll also learn why it's important to implement zero-trust to prevent data leaks and malicious workloads from being executed on a hijacked cluster. Furthermore, he will show you how to protect your cluster from being taken over by sharing useful insights, configurations, and toolsets. This talk is not intended to be an in-depth security talk, but to provide you with best practices and also make you aware of certain attack vectors and how to prevent them.

Everyone's talking about Microservices. Everyone's considering doing Microservices. Everyone's starting to use Microservices. And then everyone discovers how hard it is to develop Microservices on your local machine. Join me as we discover project "Tye," which simplifies Microservices development and flattens the learning curve of getting your services into production up and running.

Some years ago development of Java Desktop applications was easy: We just downloaded Java 8 from Oracle and got a set of useful tools and framework to develop Java desktop applications: AWT & Swing WebStart JavaFX JFX Packager If you now download a Java version from Oracle (or any other vendor) several of the mentioned tools and frameworks are gone. Some JDKs only contain AWT & Swing for desktop development and miss all the newer tools. But even if they include such tools or frameworks you have sometimes no idea about their state. In this session I will give an overview about the differences between JDKs that you can use today and how frameworks like JavaFX are really supported by the vendors. Next to this we will have a look at all the tools that are important for building and installing desktop development. Since some like WebStart are gone you can find quite good alternatives.

What does GraphQL and Traditional REST API have in common? Shouldn't the GraphQL be connected to some graphs or similar? What is actually GraphQL all about? Join me in this talk, while I try to answer all this questions and much more. In this talk I will explain what GraphQL is, what are differences and similarities compared to more traditional REST API and show you this on working examples, since code worth more then words only ;)

Presented at CASE27 Conference in Zagreb, Croatia. Abstract: Most of today’s mobile applications use one or more communication technologies to send and retrieve data stored online. In majority of these cases applications actually communicate with back-end web service which sends and receives the data. Today’s most popular architecture that deals with this functionality, is called REST (Representation State Transfer) architecture, but, implementing REST client in native Android applications usually takes a lot of time, and if it is not implemented by using some architectural pattern, time needed to modify the implementation grows proportionally with application complexity. Industry recognized one helpful framework, Retrofit, which aims to speed up the process and leaves developers more time to focus on the other important activities in the system development process. To reduce even more boilerplate code, Retrofit uses Java annotations which speed up the development process even more. Thus, in this paper we present Retrofit framework and we compare it with native implementation of Android REST client.

Proprietary performance testing platforms can be complex, expensive, and difficult to scale. With the right approach, everything from continuous integration, to continuous deployment pipelines, to full-scale production loads can be supported, but a dizzying array of platforms, services, and approaches available in AWS and the open-source community must be navigated to arrive at solutions that work. Join Gopal Brugalette and explore how to build a performance testing platform in the cloud using open source tools. Gopal shares what he has learned from his failures and successes, explains why he's made the technical decisions he did, what he might have done differently, and how to create a roadmap for success. Attendees will gain insights into building a cloud-based performance testing platform using open-source and cloud tools to improve capabilities, increase efficiency, and reduce costs.

Implementing a continuous delivery (CD) pipeline is not trivial, and the introduction of container technology to the development stack can introduce additional challenges and requirements. In this talk, we will look at the high-level steps that are essential for creating an effective pipeline for developing and deploying containerized applications. Topics covered include the impact of containers on CD, adding metadata to a container image, validating NFR changes imposed by executing Java applications within a container, and lessons learned the hard way (in production).

HTML5, CSS3, JavaScript, jQuery, Angular JS, Bootstrap, Mobile, CoffeeScript, GitHub, functional programming, Page Speed, Apache, JSON with Jackson, caching, REST, Security, load testing, profiling, Wro4j, Heroku, Cloudbees, AWS. These are just some of the buzzwords that a Java web developer hears on a daily basis. This talk is designed to expose you to a plethora of technologies that you might've heard about, but haven't learned yet. We'll concentrate on the most important web developer skills, as well as UI tips and tricks to make you a better front-end engineer. Some of the most valuable engineers these days have front-end JS/CSS skills, as well as backend Java skills.

Azure Native Qumulo scales elastically for common High Performance Compute (HPC) workloads based on application requirements for: Financial Services, Automotive, Genomics / Life Sciences, Media and Entertainment, Energy, Oil and Gas, and more. Performance can be increased (and elastically decreased) much higher than the examples shown here. These slides offer a glimpse into ANQ's HPC capabilities, although at a smaller scale. We invite YOU to do your own testing (with a free ANQ trial) and work with us to test your HPC workloads in Azure.
