Key takeaways include designing stateless applications, keeping environments similar between development and production, and preferring managed services for persistence. The document encourages decoupling infrastructure complexity from application code and ensuring applications can scale and are monitored properly.
Breaking tradition the future of package management with kubernetesLibbySchulze
This document discusses the future of package management for Kubernetes applications. It envisions declarative Kubernetes APIs that enable automated updates of packaged software. Packages would be distributed as immutable bundles in OCI registries so the exact software versions are known. A layered approach is proposed where different tools can be used for their intended purpose, such as using Kubernetes resources, YAML, or the kapp CLI. The imgpkg CLI is demonstrated as a tool for pushing, copying, and pulling bundles stored in OCI registries. The document encourages readers to help build the future of package management through the Carvel project.
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.
Openstack days sv building highly available services using kubernetes (preso)Allan Naim
This document discusses Google Cloud Platform's Kubernetes and how it can be used to build highly available services. It provides an overview of Kubernetes concepts like pods, labels, replica sets, volumes, and services. It then describes how Kubernetes Cluster Federation allows deploying applications across multiple Kubernetes clusters for high availability, geographic scaling, and other benefits. It outlines how to create clusters, configure the federated control plane, add clusters to the federation, deploy federated services and backends, and perform cross-cluster service discovery.
CSI snapshots provide a consistent backup method for Kubernetes applications. Snapshots capture all files in an application's persistent volume claim at the same time, avoiding data discrepancies that can occur with filesystem copies. While snapshots are crash consistent, they may not be application consistent without flushing data. The CSI driver framework allows storage vendors to integrate with Kubernetes without modifying the Kubernetes codebase, improving extensibility and manageability of storage backups.

VMware & Pivotal’s Pivotal Container Service (PKS) is a container management platform that provides a Kubernetes container orchestration service. PKS runs Kubernetes clusters on vSphere and VMware Cloud Foundation. It provides high availability, security and multi-tenancy capabilities. PKS integrates deeply with NSX for network and security services.
When we think about establishing a Kubernetes capability for our organization, our instinct, or perhaps just habit, might lead us to stand up a single cluster that will then be a shared resource across numerous tenants. Kubernetes offers namespaces that are intended to carve up the capacity across different users or groups of users. And while this may work well in some scenarios, it does impose certain constraints and limitations on its use. For example, it is well understood that the multitenancy in Kubernetes is soft, meaning it does not guard against deliberately malicious attacks from one tenant to another.
If instead, we align tenant boundaries to Kubernetes clusters, effectively creating many single tenant clusters we can not only avoid certain limitations but we gain some significant advantages. Add a control plane for managing these sets of clusters and we have a powerful solution built on decades of maturity in machine virtualization.
In this session we will present both models, multi-tenant clusters and multi-clusters and study the tradeoffs of each.
Securing and Automating Kubernetes with KyvernoSaim Safder
Kyverno is a CNCF Sandbox Project Created by Nirmata.
Kyverno is a policy engine designed for Kubernetes. With Kyverno, policies are managed as Kubernetes resources and no new language is required to write policies. This allows using familiar tools such as kubectl, git, and kustomize to manage policies. Kyverno policies can validate, mutate, and generate Kubernetes resources. The Kyverno CLI can be used to test policies and validate resources as part of a CI/CD pipeline.
In this session Shuting Zhao and Jim Bugwadia, both of whom are Kyverno maintainers will provide an overview of Kyverno and describe how you can get started with using it.
Serverless is a good pattern when it comes to saving infrastructure resources: why should you run apps when there’s nothing to do? The open source project Knative is often used to run functions as serverless apps in Kubernetes clusters.
In this talk, you’ll see how to leverage Knative for Kubernetes apps, not only functions. Check out how to apply serverless patterns to an existing Spring Boot / Nodejs app (backend / frontend) with a live demo.

He’ll close with a quick outlook of what’s next, including infrastructure as code, immutable infrastructure, and GitOps.
Cloud-Native Operations with Kubernetes and CI/CDVMware Tanzu
Operations practices have historically lagged behind development. Agile and Extreme Programming have become common practice for development teams. In the last decade, the DevOps and SRE movements have brought these concepts to operations, borrowing heavily from Lean principles such as Kanban and Value Stream Mapping. So, how does all of this play out if we’re using Kubernetes?
In this class, Paul Czarkowski, Principal Technologist at Pivotal, will explain how Kubernetes enables a new cloud-native way of operating software. Attend to learn:
● what cloud-native operations are;
● how to build a cloud-native CI/CD stack; and
● how to deploy and upgrade an application from source to production on Kubernetes.

Kubernetes Policy As Code usando WebAssembly | Flavio CastelliKCDItaly
Mettere in sicurezza un cluster Kubernetes richiede l'uso di diverse strategie e di strumenti per attuarle.
Tra queste, i Dynamic Admission Controllers giocano un ruolo fondamentale per garantire non solo la sicurezza di un cluster, ma anche la sua compliance. Infatti tramite di essi è possibile definire, ed applicare, regole personalizzate.
Nonostante molte organizzazioni riconoscano l'importanza di abbracciare la "filosofia" Policy As Code, sono purtroppo poche le realtà in cui questa metodologia viene utilizzata in ambienti di produzione.
Durante questo talk mostrerò come WebAssembly, una tecnologia nata originariamente per il Web, possa essere utilizzato per implementare strategie di Policy As Code in Kubernetes.
Vedremo come l'adozione di WebAssembly semplifichi il processo di creazione, mantenimento e distribuzione di queste policy.

AllTheTalks 2020: "The Past, Present, and Future of Cloud Native API Gateways"Daniel Bryant
The edge gateway has undergone several evolutions driven by changes in application architecture. Early gateways focused on load balancing and availability but evolved to support APIs and microservices. Adopting microservices and Kubernetes changes the architecture and development workflow, challenging edge management and requiring support for diverse workloads. There are three strategies for managing the edge with Kubernetes - deploying an additional gateway, extending an existing gateway, or deploying an in-cluster edge stack to simplify management. The optimal solution depends on the specific architecture and aims to scale edge management while supporting cloud-native practices.
DevOpsCon 2020: The Past, Present, and Future of Cloud Native API GatewaysDaniel Bryant
An API gateway is at the core of how APIs are managed, secured, and presented within any web-based system. Although the technology has been in use for many years, it has not always kept pace with recent developments within the cloud native space, and many engineers are confused about how a cloud native API gateway relates to Kubernetes Ingress or a Service load balancer.
Join this session to learn about:
– The evolution of API gateways over the past ten years, and how the original problems they were solving have shifted in relation to cloud native technologies and workflow
– Current challenges of using an API gateway within Kubernetes: scaling the developer workflow; and supporting multiple architecture styles and protocols
– Strategies for exposing Kubernetes services and APIs at the edge of your system
– A brief guide to the (potential) future of cloud native API gateways

It begins with discussing the need for data protection of stateful workloads on Kubernetes and challenges with current approaches. It then provides an overview of Kanister, an open source tool for application-level data protection on Kubernetes. Kanister uses custom resources and functions to abstract away complex data protection workflows. It also works with Argo Workflows to scale parallel data operations. The document concludes with a demo of using Kanister's CSI functions to create and restore snapshots and scaling snapshots with Argo Workflows.
This document discusses 10 common fallacies in platform engineering. It begins by introducing the speaker and topic, which are 10 fallacies seen in platform engineering and how to mitigate them. Some of the fallacies discussed include prioritizing the wrong procedures, relying only on visualizations, trying to replace all tools at once, providing too much freedom without constraints, and trying to compete directly with large cloud providers. The goal of platform engineering is to standardize processes and reduce cognitive load on developers and operations teams.
This document introduces Fluvio, an open-source data streaming platform founded by the creators of Nginx's open-source service mesh. It provides a programmable platform for data in motion that can be used to build analytics pipelines, track user behavior and sensor data, and enable fraud detection. Fluvio offers better performance and lower costs compared to Kafka. The roadmap details ongoing development of Fluvio and its cloud offering from InfinyOn, including adding smart modules, connectors, and pipelines.
This document discusses Sigstore, a new standard for signing, verifying, and protecting software. It provides three key pieces - Cosign for signing things, Fulcio for signing with short-lived certificates, and Rekor for verification and monitoring. Sigstore allows signing of software artifacts, documents like SBOMs and attestations, and git commits. Attestations provide signed statements about software, and Sigstore ensures their integrity. Sigstore supports achieving different levels in the SLSA framework for supply chain security. It also aligns with frameworks from NIST and CIS. Tools like Gitsign allow "keyless" signing of git commits to meet requirements for verified history and two-person review.
This document summarizes a presentation on avoiding configuration drift with Argo CD. It introduces configuration drift as differences between environments that are supposed to be similar, such as undocumented changes or "cowboy deployments". It then discusses how configuration drift can occur in Kubernetes and strategies like GitOps and Argo CD that use bidirectional synchronization between code repositories and clusters. This helps guarantee clusters always deploy the desired configuration from Git and can self-heal if manual changes are made. The presentation includes a live demo of these concepts using Rancher and Argo CD.
This document summarizes a virtual meetup on app modernization. It discusses that 79% of app modernization efforts fail, with the average cost being $1.5 million and time being 16 months. App modernization aims to improve scalability, engineering velocity, and remove technical debt. Common obstacles include complexity, technical debt, and lack of resources. Modernizing just the UI without the business logic is ineffective. The document recommends prioritizing modernizing the business logic first to achieve the most benefits, and provides guidance for successful modernization projects such as defining requirements, securing resources, training teams, and providing the right tools.
CNCF Live Webinar: Low Footprint Java Containers with GraalVMLibbySchulze
GraalVM Native Image can compile Java applications into native executables for improved performance and lower resource usage compared to the traditional Java Runtime. It works by ahead-of-time compiling Java applications into native images that have a smaller footprint when deployed in containers and start faster than traditionally interpreted Java applications. Native images generated by GraalVM Native Image were shown to use half the memory and achieve better throughput than the same application running on the Java Runtime when deployed to Oracle Kubernetes Engine.
This document summarizes a workshop about using EnRoute and Open Policy Agent (OPA) to enforce policies at the ingress level.

The advent of social media has revolutionized communication, transforming the way people connect, share, and interact globally. At the forefront of this digital revolution are visionary entrepreneurs who recognized the potential of the internet to foster social connections and create communities. This essay explores the founders of some of the most influential social media platforms, their journeys, and the lasting impact they have made on society.
Mark Zuckerberg, along with his college roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes, founded Facebook in 2004. Initially created as a social networking site for Harvard University students, Facebook rapidly expanded to other universities and eventually to the general public. Zuckerberg's vision was to create an online directory that connected people through their real-life social networks.
Twitter, founded in 2006 by Jack Dorsey, Biz Stone, and Evan Williams, brought a new dimension to social media with its microblogging platform. Dorsey envisioned a service that allowed users to share short, real-time updates, limited to 140 characters (now 280). This concise format encouraged rapid sharing of information and fostered a culture of brevity and immediacy.
Kevin Systrom and Mike Krieger co-founded Instagram in 2010, focusing on photo and video sharing. Systrom, who studied photography, wanted to create an app that made mobile photos look professional. The app's unique filters and easy-to-use interface quickly gained popularity, amassing over a million users within two months of its launch.
Instagram's emphasis on visual content has had a significant cultural impact. It has popularized the concept of influencers, giving rise to a new industry where individuals can monetize their popularity and reach. The platform has also revolutionized digital marketing, enabling brands to connect with consumers in more authentic and engaging ways. Acquired by Facebook in 2012, Instagram continues to be a dominant force in social media, shaping trends and cultural norms.
Reid Hoffman founded LinkedIn in 2002 with the goal of creating a professional networking platform. Unlike other social media sites focused on personal connections, LinkedIn was designed to connect professionals, facilitate job searches, and foster business relationships. The platform allows users to create professional profiles, network with colleagues, and share industry insights.
LinkedIn has become an indispensable tool for job seekers, recruiters, and businesses. It has transformed the job market by making it easier to find and connect with potential employers and employees. LinkedIn's influence extends beyond job searches; it has become a hub for professional development, thought leadership, and industry news. Hoffman's vision has significantly impacted how professionals manage their careers and build their networks.
