Cloud Native Security for the Rest of Us - Tiffany Jernigan, VMware

Your mission is to secure the vast tracts of land of the Cloud Native security landscape. Where do you even start?!? It would be preposterous to cover that whole topic in a single session, but we can at least map it out. Our plan is to break it down into three key areas and review each in turn. * Platform - securing and upgrading our control planes and nodes; isolating compute, storage, and network resources; managing privileges and secrets. * User management and permissions - various ways to authenticate and authorize user access; leveraging tools like RBAC and Namespaces, and some common "gotchas". * Software supply chain - what that means; some actual threat models are; how to mitigate them. You will leave this session with a stronger understanding of the breadth and depth of Cloud Native security and resources to further develop your knowledge.

Confidential Computing and Privacy-Enhancing Technologies - The Landscape - Mike Bursell, Profian

“If the cloud is just somebody else’s computer, then how can I trust my sensitive apps and data to it?” This question – which inhibits adoption of public cloud computing for many organizations in security-sensitive or highly regulated industries – finally has some answers, provided by a variety of technologies. This session covers the (TLA-laden) landscape of key technologies, from FHE (Fully Homomorphic Technologies) to TEEs (Trusted Execution Environments, the basis for Confidential Computing), and beyond. We will compare the various approaches, the underlying technologies, and the properties that they can offer to organizations working out how to manage the risks associated with deploying to the cloud, the Edge and beyond. We will also look at why open source is playing such an important role in some of the projects embracing these technologies, including a demo of a sensitive application using the Enarx project, an open source project which is part of the Confidential Computing Consortium (Linux Foundation). This talk does not require deep technical knowledge, though it will lead pointers. Nor will it try to paint any technology as “the answer”, but will provide some guidelines about which approaches may be best suited to your organization’s environment and requirements.

Sponsored Session: Policy as Code with Open Policy Agent - Anders Eknert, Styra

Should user Alice be allowed to read credit reports? Should a cloud instance be deployable without basic security configuration in place? Should service X be allowed to query the database? Policy defines the rules of our systems, but how do we ensure our policies are enforced consistently in increasingly distributed and diverse tech stacks? In this talk we’ll explore the benefits of decoupling policy from our applications, deployment pipelines and platforms, and how Open Policy Agent (OPA) can help unify the way we work with policy across the stack.

Distributed Tracing Integration with OpenTelemetry and Knative - Daniel Oh, Red Hat

Scaling application platforms give site reliability engineers a significant burden on collecting telemetry data from a single cluster to multiple clouds. You’re probably handy to observe metrics with comprehensive dashboards by 3rd party application performance monitoring tools in the traditional environments. However, the application topologies are getting more complex due to distributing cloud-native microservices. Infrastructures have also been varying from Linux containers to IoT edge devices, public cloud, and Kubernetes. This is a new challenge for dev and ops to trace application chains. This talk guides you through the distributed tracing integration with OpenTelemetry for serverless functions. OpenTelemetry allows you to collect telemetry data such as metrics, logs, and traces then enables you to analyze applications’ performance and behavior. I’ll also showcase a live demo of how to trace metrics of reactive RESTful APIs with step by step instructions below: - Collect local telemetry data by OpenTelemtry collector and Quarkus Dev mode - Visualize the telemetry data through the Jaeger console locally - Deploy the reactive serverless functions to verify telemetry data using OpenTelemetry and Jaeger operators

Is OpenStack Still Needed in 2022? - Thierry Carrez, Open Infrastructure Foundation

Over the past 10 years, OpenStack has become the de-facto standard for providing cloud infrastructure using open source solutions. But in the past 5 years, the ecosystem focus has shifted higher in the stack onto cloud-native solutions, which run on top of an existing cloud infrastructure. Does that mean that open source cloud infrastructure solutions, like OpenStack, are no longer relevant? In this talk, Thierry Carrez, the General Manager for the Open infrastructure Foundation, the non-profit hosting the OpenStack project, will explore this question. After examining the motivation and history of OpenStack over the past decade, we will explore what makes OpenStack relevant in the next decade, with a special attention to the European context. While it is not for everyone, new use cases like Digital Sovereignty or Edge computing are driving renewed adoption of OpenStack, especially in combination with Kubernetes (what is called the Linux OpenStack Kubernetes Infrastructure, or LOKI).

The Challenges and Solutions of Open Edge Infrastructures - Ildiko Vancsa, Open Infrastructure Foundation

During the past decade cloud computing outgrew the walls of traditional large data centers and started to take over the edge. This technology evolution opened up endless opportunities to create new applications along with better utilizing hardware resources that are closer to the end users. These new opportunities also brought in new challenges, such as complexity, and put well-known ones, like interoperability, back into the spotlight. End-to-end edge infrastructures often grow to a massive scale in a geographically distributed fashion, which results in innovative, but complex solutions that requires high level of automation to handle. Along with the high demands in the software space, hardware solutions are also becoming more diverse that the software layer has to seamlessly support from the core out to the edge. This talk will use current and upcoming use cases to describe the challenges of building and operating infrastructure from core to edge. It will also introduce an open source edge cloud solution, StarlingX, that is already running in production around the globe. The presentation will show how the project is addressing the needs of geographically distributed systems on a large scale.

Open Source Ops Fast Track with Operate First - Marcel Hild & Oindrilla Chatterjee, Red Hat

Open source has become the defining way of developing software. But what’s next after releasing the code? Building an infrastructure for a project is hard. What CI/CD pipelines should I use, how to deploy - can I integrate with other services, where are my users? The Operate First community cloud is an environment for developing and operating Cloud Native software and a community of developers, DevOps, and SREs to learn from each other. Built on git-ops and open-source principles with open deployments and operational knowledge, the community provides a solid foundation for your project, so that you can focus on your solution. When the Open Source Climate initiative started out building an open data science platform that aggregates open climate data sets, they required an environment that supports complex data ingestion, processing, and quality management. You will learn how the team took advantage of the Operate First community-supported infrastructure, resolving foundational problems quickly and freeing time to work on the climate and data science problems. We’ll take you on a ride through cloud operations, by re-visiting the journey of the OS Climate community, explaining how your project or community can also become part of a fully open source community cloud.

Sponsored Session: Killing the Reverse Proxy from the Inside: the Evolution of NGINX Unit - Liam Crilly, NGINX

NGINX as a web server and reverse proxy has been integral to the architectural patterns for web services and applications for over a decade. From the LEMP stack, to containerized apps, to Ingress Controllers for Kubernetes. But in another open source NGINX project, there is a mission to kill the reverse proxy because it represents an unnecessary layer in the application stack that results in application behaviour being described in several places. In this session we explore the challenges of distributed configuration in cloud-native infrastructure, and the complexities that this leads to. We contrast this with the benefits of killing the reverse proxy and designing for a simpler application stack. Finally, we introduce NGINX Unit, created by the original NGINX team on an evolved architecture with a vision of delivering a simpler architecture for web applications.

Scaling SLOs with Kubernetes and Cloud Native Observability - George Hantzaras, Citrix Systems

Defining Service Level Objectives and Service Level Indicators is a really important aspect of implementing SRE. Through service metrics (SLOs, SLIs, Error Budgets), SRE can help us measure our system’s performance and improve customer experience. They not only enable your teams to monitor and plan around reliability, but can also be early predictors of customer satisfaction, NPS, churn rates, and more. With the rise of cloud native technologies, it has become more and more relevant to automate our observability, extending it to an SLO-as-code model. In this session we’ll see how SLOs have evolved and can be used in a Cloud Native world. We’ll then explore how technologies like Kubernetes and Prometheus can help us scale SLOs, while promoting best practices and standards using Observability as code. Finally, we’ll see how to put all these together with Jenkins and Rancher, to operationalize error budgets.

Kubetest2: Because Now You Can Test Kubernetes on Your Bespoke Cloud Too! - Priyanka Saggu, VMware

Do you want to test Kubernetes end-to-end on your cloud? Also curious to know how other projects in the Kubernetes ecosystem do this? If so, you will love our Kubetest2 session. Kubetest2 is a testing framework maintained by Kubernetes SIG Testing that allows you to test Kubernetes both locally and on the cloud. It manages cluster configuration, e2e testing, log collection, and test environment disposal. Kubetest2 natively supports GCP, GKE & KinD deployers, but also enables writing custom deployers out-of-tree. A custom Kubetest2 deployer is possible, but it needs some prior context & knowledge of Kubetest2 internals. To that end, this talk will provide attendees with the following takeaways: * What is Kubetest2, how it is architected, and its evolution from its predecessor Kubetest * Benefits of using Kubetest2 as a testing tool for your project * Reasons to use a bespoke Kubetest2 deployer Finally, we will demo how to develop a custom deployer for your own cloud provider.

The Force Awakens: Managing Millions of Kubernetes Clusters at the Edge - Di Xu, Tencent

The benefits and paradigms offered by cloud native, such as observability, loosely coupled systems, declarative APIs, robust automation and etc, have made Kubernetes an ideal go-to platform for the edge. And Kubernetes is extending to the edge rapidly. The challenge with the edge is to take all these learnings and benefits from Kubernetes and transfer them to the edge. How does a single/small organization manage thousands of millions of clusters and thousands of millions of applications running on disparate and disaggregated infrastructure without the need to juggle different management tools for each environment? In this presentation, they will bring in a novel engineering perspective to unveil the power of millions of Kubernetes clusters to the edge. Also they will share all the lessons learnt and practical tips & tricks on such massive clusters management. In the end, a benchmarking will be given.

Two Roads Diverged in the Observability Woods: I Took the E2E One - Prashansa Kulshrestha, Postman Inc.

In the past few years, we have seen rapid development in system designing where multiple services coordinate with each other to form a whole end-to-end architecture. Along with this, our testing methodologies have also improved by using end-to-end tests. What about observability though? End-to-end observability is still a dream for many organizations. How do we know which application is underperforming? What causes it to underperform? Is it taking other applications down with it? Which users are getting affected? It’s high time that we stop tailing logs or worse, deriving metrics out of these logs to understand our system’s bottlenecks. Application Performance Monitoring (APM) can help us here. It can not only provide you with the necessary metrics but also other benefits like understanding your application’s transactional behaviour via traces, visualising how your application communicates with external entities, etc. Do you want to know how your users are reacting to your application’s performance? Yes, that’s possible. In Prashansa’s experience of working with APM for the past year, she has done enough mistakes so that you don’t have to repeat them. With this talk, she wants to share how APM along with OpenTelemetry can help to debug problems before they occur.

Deep Dive into Building Streaming Applications with Apache Pulsar - Timothy Spann, StreamNative

In this session I will get you started with real-time cloud native streaming programming with Java, Golang, Python and Apache NiFi. If there’s a preferred language that the attendees pick, we will focus only on that one. I will start off with an introduction to Apache Pulsar and setting up your first easy standalone cluster in docker. We will then go into terms and architecture so you have an idea of what is going on with your events. I will then show you how to produce and consume messages to and from Pulsar topics. As well as using some of the command line and REST interfaces to monitor, manage and do CRUD on things like tenants, namespaces and topics. We will discuss Functions, Sinks, Sources, Pulsar SQL, Flink SQL and Spark SQL interfaces. We also discuss why you may want to add protocols such as MoP (MQTT), AoP (AMQP/RabbitMQ) or KoP (Kafka) to your cluster. We will also look at WebSockets as a producer and consumer. I will demonstrate a simple web page that sends and receives Pulsar messages with basic JavaScript. After this session you will be able to build simple real-time streaming and messaging applications with your chosen language or tool of your choice.

How to Get Your Application Developers to Fall in Love with Kubernetes & Cloud Native Applications - Lukonde Mwila, SUSE

As per the latest CNCF survey, Kubernetes and containers have gone mainstream! This is exciting for most DevOps and SRE operators. However, it also introduces new and different challenges for application developers who, for example, just care about building out a great React.js frontend application. In many cases, the widespread adoption of certain technologies doesn’t necessarily equate to the wide spread adoption of best practices. The latter is an issue for developers who don't believe that the Kubernetes world should fall within their purview. These application developers are having to quickly adopt cloud native approaches and tools to development whilst still fulfilling development of business requirements, and it's a recipe for implementing bad Kubernetes practices. So how can teams successfully adopt cloud native application modernisation without a negative impact on developer experiences and workflows, and still deliver best practices of K8s resources? Lukonde will discuss and demonstrate tools that support the optimisation of the inner development loop, abstraction of local building and delivering of containers to a local Kubernetes cluster, and policy enforcement practices to safeguard against committing insecure and badly formed manifests and helm charts.

How Geo-Distributed Apps Use Global Cloud Infra for Speed and Compliance - Denis Magda, Yugabyte

An infrastructure of major cloud providers spans dozens of geographical regions and availability zones. With this infrastructure, any application can serve user requests with low latency regardless of whereabouts, bringing the application experience straight to users’ doors. It can also easily comply with data residency requirements when expanding to new territories. Come and learn how to design geo-distributed applications that achieve low latency and comply with GDPR regulations (and similar) by: * Spreading data across multiple availability zones, regions, and even cloud providers. * Serving user requests with microservices closest to the user location. * Using a combination of synch and async communication channels to replicate data and exchange events between cloud regions of different proximity.

How to Coordinate Your Multi-cluster Kubernetes Environment with Ease - Laszlo Bence Nagy & Varga Zsolt , Cisco

Kubernetes is great for single cluster use cases, but organizations often need to manage multiple clusters together. Unfortunately, the same declarative approach and feature set extended across multiple clusters is not available yet. Most projects proposed by the Multicluster SIG for solving this problem use a centralized approach. Cluster Registry is an open-source, non-centralized, fully decoupled and highly customizable tool, which helps you solve most multi-cluster related goals.
