The astonishing value of speed
Intraday lead times? Bringing a new idea out to your users in just a few hours? Irrelevant for you? Deployment once a week is sufficient? That is what many companies in Germany still think. In this session we will discuss why this conception is wrong. We will discuss how intraday lead times are basically inevitable even if you do not live in a highly dynamic market. We will see how you can save lots of money, become more flexible, how you can simplify your organization and processes, how you can reduce stress (!) and a lot more, just by going for intraday lead times. Be prepared for some surprises and get ready for a speed boost.

Lessons Learned: arc42 in einem DevOps Team
In diesem Vortrag berichte ich von meinen Erfahrungen, Erfolgen und Fehlern mit dem arc42-Architekturtemplate in einem DevOps-Team im Konzernumfeld mit Produktentwicklungsfokus. Produktentwicklung ist geprägt von kurzen Iterationszyklen und wird darum gerne agil betrieben, wie im Team des Sprechers. Dort wurde die vorhandene unstrukturierte Dokumentation in das arc42-Template überführt und in einem Wiki abgelegt. Im Laufe der Zeit stellte sich heraus, dass das Tooling eine entscheidende Rolle für die Qualität der Dokumentation bedeutet und deswegen auf Docs-as-Code umgestellt. Im Laufe des Vortrags wird auf die wichtigsten Entscheidungspunkte für die aktuelle Iteration der technischen Softwarearchitektur eingegangen. Darunter unter anderem der Umgang mit "Entwicklerprosa", veralteter Dokumentation und der für ein DevOps-Team besonders wichtigen Architekturentscheidungen. Die Einbindung in das methodische Vorgehen Kanban wurde mit arc42 und einer Microsite basierend auf AsciiDoc möglich. Nicht ausgespart werden die gemachten Fehler, wie zum Beispiel fehlende Qualitätssicherung erstellter Dokumentation oder die Vermischung von fachlichen und technischen Themen.

[LIVE CODING] REST in peace, Apache Kafka is alive
Nowadays every Java Developer can write a REST microservice, but it's also possible to use messaging with Apache Kafka! Messaging is typically used for event streaming and can be compared by a pipeline of sending or receiving (big) data. It's quicker, can handle a lot of data and is easy to use. Let's create a Spring Boot application with a producer and consumer. Time to see it in action!

Howto: Options Galore to Get from Source Code to Container
A typical workflow in a modern software dev project can look like: Build code, put built artifact into container image, put container image into registry, deploy to Kubernetes. Each step has it’s own requirements and pitfalls alike. The overall goal is most often to bake those steps into easily repeatable pipelines and enable a high degree of automation and standardisation. Dockerfiles seems to be the choice with the highest adoption when it comes to containerizing code artifacts. However there are options, which might remove some of the pitfalls and standardize the entire process even more. The talk will give deeper insights by comparing (multi-stage) Dockerfiles to Cloud-Native Buildpacks (buildpacks.io/paketo.io) and Google’s JIB under the evaluation criteria of build time, build size, standardisation, robustness and security. The examples and live demo will have certain focus on Java-based frameworks (Spring Boot, Quarkus, Java EE), but coverage of other languages will also be included and highlighted. The intended take-away of the session is a better overview of container building and deployment options along with understanding of requirements, advantages and drawbacks.

How the SRE fit´s into the DevSecOps World?
DevOps and SRE seem to be two approaches to the same obstacle. Both approaches aim to close the gap between development and operations teams, with the unified goal of optimizing the production and operation cycle without compromising its efficiency and effectiveness. Both titles coexist in the same room and are an integral part of the development team. How do they differ, and what does each one mean? And how can the topic of security be established in such a constellation?

Bridging the Gap Between Ops and Developers with CI/CD
Software development has changed dramatically in recent years; no longer can you afford to say, “That’s how we’ve always done it.” Applications are evolving rapidly, which requires you to move fast and fix things. And don’t neglect the cultural shift inherent in any technical change. (Some developers, for instance, reject build-break notifications, going so far as removing themselves from the email list.) If you’re just starting your CI/CD journey, you must ensure everyone understands the benefits, including increased speed-to-market, stable builds, and reduced drama around releases. That way, CI/CD won’t just help you deliver for your customers—it will help you sleep better at night.

Which JVM Version are you using and why is it still Java 8?
These simple questions can reveal a lot about your software development process. So, this talk is not about the features of an specific Java Version nor a comparison among different Java releases but rather about the path to the holy grail of software: feedback based development. What is that exactly? How can you reach such a high stage of software development? What are the common pitfalls? How can you tackle them? Do you really need to do feedback based development? All of these topics and more will be discussed in this talk.

Wednesday, October 6
 

10:00 CEST

Do You Need Kubernetes or a PAAS?
Kubernetes can manage the containers that run your application more easily than if you need to handle them individually. A Platform As A Service (PAAS) solution takes away the burden to deep dive into a framework and can handle many tasks for you. Since Kubernetes has its own challenges, is a PAAS solution preferred? The answer to this question depends on your situation, of course. In this session we go a bit deeper in comparing the process of setting up a Kubernetes Cluster yourself with using a PAAS that manages it for you. We will also demonstrate the simple steps to bring your Jakarta EE application to the cloud with Payara Cloud, with no Kubernetes knowledge needed.

Cloud Security in Action ! - ein Finanzdienstleister geht in die Cloud
Die Digitalisierung traditioneller Unternehmen und damit meist zwingend verbundene Modernisierung der IT macht auch vor dem Sektor der Finanzdienstleister nicht Halt. In diesem Vortrag berichtet die SüdLeasing - eine 100% Tochter einer Landesbank - von ihrem Weg von der “legacy IT” zur modernen cloud-basierten Umgebung. Aufgrund der Sensitivität der Daten lag von der ersten Sekunde ein besonderer Fokus auf dem Thema Cloud Security. Hier berichten Tamira Horn und Thorsten Jakoby von der Reise eines BaFin regulierten Finanzdienstleisters in die Cloud. Statt "das sichern wir durch eine Firewall und Netzwerke", wurden Multi-Tenant-Zero-Trust-Architekturen aufgebaut. Business Continuity und Disaster Recovery wurden voll automatisiert mit Hilfe von Terraform, Access Control Lists und Microsoft Azure aufgebaut. Wir zeigen mit Beispielen und Demo's wie wir es technisch umgesetzt haben, nicht das Rechenzentrum in die Cloud zu migrieren, sondern eine sichere und flexible Plattform zu designen, um uns auf den Weg in die Cloud vorzubereiten.

APIOps - Automatisierte Prozesse für bessere APIs
Die Entwicklung von APIs beginnt immer mit der alten und mittlerweile langweiligen Schlacht von API oder Code first. Aber die Arbeit mit APIs bezieht sich auf einen Prozess, der Design, Entwicklung und Betrieb umfasst. Mit diesen Gedanken im Hinterkopf und den Möglichkeiten von API-Gateways und -Plattformen, diese Prozesse zu unterstützen, stellt sich sehr schnell die Frage, wie diese Prozesse automatisiert werden können. Daniel Kocot zeigt in seiner Session auf, wie API-Gateways oder -Plattformen den Entwicklungsprozess von APIs nach der DevOps-Idee und dem CALMS-Modell positiv beeinflussen können, um den Konsumenten bessere APIs zu liefern.

Rolling Stones – vom Release überrollt
Jeder macht es, manche sogar mehrmals täglich. Aber nur wenige kennen die komplexen ineinander greifenden Mechanismen, die ein vollständiges Software Release ausmachen. Deshalb kommt es hin und wieder vor, das sich ein Paket in der automatisierten Verarbeitungskette querstellt. Mit ein wenig Theorie und einem typischen Beispiele aus dem Java Universum zeige ich, wie man ein wenig Druck aus dem Softwareentwicklungsprozess nehmen kann, um zu schlanken leicht automatisierten Prozessen gelangt.

Automation is simple now using Devops
The data held in your Databases is an integral part of every application, so why aren’t we talking about it more when it comes to DevOps, and including DBAs in this important conversation? In this session learn why the database has been left behind and the special challenges it presents when it comes to delivering value quickly. Explore the similarities to application development and see that even though there are challenges, it is possible to include your database in DevOps processes such as version control, continuous integration, and continuous delivery.

The Quick Wins of DevSecOps
I always like to be out in the forest, enjoy the quiet, and pursue my thoughts undisturbed. And recently, a question occurred to me that I get asked again and again at conferences, meetups or workshops: The question is almost always: What are the quick wins or low hanging fruits if you want to deal more with the topic of security in software development? And I want to answer this question right now!

State of the Java Metrics Libraries
Java developers have to choose from a variety of libraries when they want to export metrics in their Java applications. There is the MicroProfile standard that emerged out of the popular Dropwizard library. There is Micrometer which was developed as part of the Spring framework but is more and more adapted beyond the Spring ecosystem. And there is the Java client library provided by the Prometheus project itself. This talk gives an overview of the current state of Metrics libraries in the Java ecosystems. We present the differences, pros, and cons of the current options, and highlight some points that should be considered when deciding which library to choose.

Expanding the scope of refactoring to fix Java security problems
Refactoring code is a second nature primarily for Java developers, because Java IDEs embraced refactorings pretty early. But, why limit refactoring only to make code maintainable and understandable? What if there were refactorings that go beyond behavior preservation and make code more secure, more reliable, and run faster? That would require tools that rewrite code with surgical precision, such that the undesirable behavior of the code is fixed, while the good path behavior of the code remains intact. Being integrated with source code and development process, refactorings and program transformations not only help maintain good code, but also teach developers about how to write and appreciate good code.
