In großen Unternehmen entwickeln viele Teams REST APIs. Dabei gibt es einige Aufgaben, die sich wiederholen: z.B. Validierung, Test und Publikation. Der Aufbau einer API Operations Pipeline zur Automatisierung dieser Aufgaben ist aufwändig. Dieser Talk zeigt am Beispiel von Azure DevOps Templates, wie so eine Pipeline als Service angeboten werden kann. So kümmert sich ein spezifisches Team um die Entwicklung und Wartung der Pipeline, während alle anderen sich auf das Design und die Entwicklung…

As more organizations are moving to the cloud, cloud architectures are getting more sophisticated by having a kind of technology diversity. This includes for example container orchestrators, database services, networking components & virtual machines.
When it comes to security, observability on this diversity is paramount. The main question here is, do you really perceive when your app landscape is under attack?
In this session, you'll have the opportunity to see various attack vectors & ways to…

"Which programming language is the fastest" usually is everyone's first thought when green software is mentioned! It's a common deduction that the fastest code is, therefore, the most efficient, which then, of course, can save us from this climate disaster. However, code efficiency is not even half of the story! In this talk, Sarah will review the three approaches that make software green. She will also introduce efficiency-achieving practices that can take us closer to fighting this pesky…

Data, the way that we process it and store it, is one of many important aspects of IT. Data is the lifeblood of our organizations, supporting real-time business processes and decision-making. For our DevOps strategy to be truly effective we must be able to safely and quickly evolve production databases, just as we safely and quickly evolve production code. Yet for many organizations their data sources prove to be less than trustworthy and their data-oriented development efforts little more than…

Organizations are drawn to migrate their systems into the cloud, but in practice, cloud transformations do not always succeed in achieving the advantages often promised by cloud providers, such as scalability, availability, and cost effectiveness.
We give an overview over Kevin Hoffmann's fifteen factors for cloud-native applications and how they help us achieve success in our cloud migrations.

Target Audience: Architects, Developers, Operations, DevOps
Prerequisites: Basic understanding of web…

"Σπεύδε βραδέως" in ancient Greek, or "festina lente" in Latin translates as "hurry slowly" an oxymoron saying to indicate the need for balancing deliberation and urgency.
In this talk we comment on the prevailing perceptions relating to speed of software development and how in a DevOps context what sometimes is perceived as fast from an individual's perspective has a deleterious effect on team performance while practices traditionally viewed by developers as cumbersome have in fact a positive…

Eine explizite Softwarearchitektur ist der Garant für erfolgreiche Softwareprojekte. Zur Unterstützung der Kommunikation braucht es eine inhaltlich hinreichende und aktuelle Dokumentation. Der Docs-as-Code-Ansatz unterstützt, indem die Dokumentation in Form leichtgewichtiger Text- und Grafikformate näher an den Quellcode gebracht, in der Versionsverwaltung abgelegt, mit leichtgewichtigen Entwicklerwerkzeugen (IDE/Texteditor, Build-Tools, CI/CD-Pipelines) bearbeitet und in die…

Kubernetes ist omnipräsent. Entweder laufen die Anwendungen in Kubernetes oder sollen in Kubernetes laufen. Entwickler mögen sich jetzt denken "Aber was hat die Kubernetes-Infrastruktur mit mir als Entwickler zu tun?"
Dieser Vortrag gibt eine Kurzeinführung, was Kubernetes ist und aus welchen Komponenten es besteht. Beim Durchgehen der Komponenten und Konzepte steht die Sichtweise eines Entwicklers im Vordergrund. Am Ende nehmen die Zuhörer Good Practices anhand von Beispielen mit nach Hause.

Warum reden Entwickler und Operator so oft aneinander vorbei?
Warum können sich viele Entwickler gar nicht vorstellen, wie die IT abseits ihrer JVM tickt?
Warum stoßen Entwickler auf Probleme, sobald es hardwarenaher wird?
Warum ist das Anbinden von Hardware für viele Entwickler ein Problem?
Warum versuchen viele Entwickler, alle Fehler mit dem Debugger in ihrer IDE zu finden?

Zielpublikum: Architekt:innen, Entwickler:innen, Projektleiter:innen
Voraussetzungen: Projekterfahrung als Entwickler…

At Tchibo we wanted to reduce our server and energy consumption with our product development teams. But why would we care? We all like fast snappy development and test systems. And our shop needs to survive Black Friday’s shopping traffic. Annual Google Cloud consumption forecasts do not trigger us to consume less. But when we started to show teams their related carbon dioxide footprint, we created a feedback loop that will help us to become better CO₂-developers.
As developers, we have an…

DevOps isn't dead yet and it will not die in the future. Platform engineering comes to leverage DevOps practices horizontally to support developers, operations and those in between. In this session, I will give you a perspective on how to move on from DevOps to Platform Engineering, how to design and shape your internal platform and build a vibrant community sharing best practices and enabling each other to overcome faster issues. In the end you will understand how we can reduce the cognitive…
