The document describes the twelve-factor app methodology for building software-as-a-service applications. The twelve factors are: codebase, dependencies, configuration, backing services, build-release-run, processes, port binding, concurrency, disposability, logs, admin processes, and dev/prod parity. The methodology advocates designing apps that are optimal to deploy on modern cloud platforms by separating an app from its infrastructure, using declarative formats for setup automation, and enabling continuous deployment for maximum agility.

Continuous Lifecycle | ContainerConf, November 2020, Vortrag von Mario-Leander Reimer (@LeanderReimer, Chief Software Architect bei QAware) === Dokument bitte herunterladen, falls unscharf! Please download slides if blurred! === Abstract: Wenn es darum geht, Kubernetes auf Hardware mit eingeschränkten Ressourcen wie einer lokalen Entwickler-Workstation oder Edge- und IoT-Geräten zu betreiben, ist eine volle Kubernetes-Distribution nicht die ideale Wahl. Viel besser dafür geeignet ist stattdessen eine neue Generation von leichten und dennoch zertifizierten K8s-Distributionen. In diesem Vortrag werden wir uns zwei beliebte Optionen genauer ansehen: MicroK8s und K3s. Nach einem kurzen Überblick der jeweiligen Funktionen unterziehen wir beide Kandidaten einem Live-Praxistest auf realer Hardware. Dieser Vortrag ist Hands-on und unterhaltsam zugleich, und zeigt, dass man als Entwickler keinen Doktortitel in K8s Clusterology benötigt.

With the growing adoption of Kubernetes, organizations want to take advantage of containerized Microsoft SQL Server 2019 to optimize transactional performance and accelerate time-to-insights from their business-critical data. However, as enterprises embrace hybrid cloud strategy, they need to consider several aspects based on the performance, cost and data protection requirements for running enterprise-grade SQL Server databases. In this webinar, we will compare and contrast various cloud-native platforms for SQL Server that would help CIOs, DevOps engineers, database administrators and applications architects to determine the most suitable platform that fits their business needs. Join us as we explore some exciting results from a recent performance benchmark study conducted by McKnight Consulting Group, an independent consulting firm, to compare the performance of Microsoft SQL Server 2019 on the best possible configurations of the following Kubernetes platforms: Diamanti Enterprise Kubernetes Platform Amazon Web Services Elastic Kubernetes Service (AWS EKS) Azure Kubernetes Service (AKS) Topics will include: Platform considerations and requirements for running Microsoft SQL Server 2019 Performance comparison and analysis of running SQL Server on various platform Best practices for running containerized SQL Server databases in Kubernetes environment

Last year we tasted the very first bits of the NET Core platform. The RTM is out and we are close to the next 2.0 version. Is this the right moment to adopt the platform? What are the changes of the new project system brought from Visual Studio 2017? What is new in the tools, sdk and packaging? Adopting the new NET Core doesn’t necessarily mean migrating everything in a single step but mixing it with the regular .NET Framework thanks to the new net standard which is evolving to the 2.0 version as well. During this code-first session, we will try to see the developer’s and architect’s perspectives in a variety of scenarios, including the cross-platform and Raspberry.

- Operators are applications that extend Kubernetes to manage complex stateful applications. They use custom resource definitions (CRDs) to configure and automate tasks. - Helm is a good starting point for creating operators as it is widely used and easy to learn. Operators created with Helm can later be used to manage resources in other operators. - The demo showed creating a Helm operator from a Nginx chart and combining two operators with ArgoCD to deploy example apps based on custom resources.

Kubernetes allows organizations to achieve economies of scope by providing consistent operations and a developer experience across infrastructure. It enables a shift from operator-driven IT to intent-driven IT managed through APIs rather than tickets. Kubernetes can function both as a platform for modern applications and as a modern application platform by providing the highest level of abstraction while allowing for lower-level configurations. This decouples systems and teams with APIs serving as the unit of collaboration, effectively delivering software as a service. However, adoption may be limited by skills, accessibility, and inertia within organizations.
