Why Kubernetes as a container orchestrator is a right choice for running spark clusters on cloud?

The intent of this talk is to share the experience of building such a service and deploying it on a Kubernetes cluster. In this talk we will discuss all the requirements which an enterprise grade Hadoop/Spark cluster running on containers bring in for a container orchestrator. This talk will cover in details how Kubernetes orchestrator can be used to meet all our needs of resource management, scheduling, networking and network isolation, volume management etc.

Spark performance tuning for Kubernetes/Serverless workloads

Cloud platforms provide flexibility of creating Spark clusters for short duration either as Function as a server or on Kubernetes. But, it is important to ensure that the spark jobs are written and executed in a way as to get the best mileage from these clusters. Given that the Clusters are billed on the duration of time used, performance of jobs becomes critical not only to improve efficiency but to reduce the Total Cost. This talk covers practical tips and hints on how to tune Spark jobs on popular Resource Managers like Yarn,Kubernetes for best performance. This talk will also address some of the FAQs by users and customers on Spark Clusters on popular Cloud platforms.

Battle of the Circuit Breakers: Hystrix vs Istio

Kubernetes in general, and Istio in particular, have changed a lot the way we look at Ops-related constraints: monitoring, load-balancing, health checks, etc. Before those products became available, there were already available solutions to handle those constraints. Among them is Hystrix, a Java library provided by Netflix. In particular, Hystrix provides an implementation of the Circuit Breaker pattern, which prevents a network or service failure from cascading to other services. But now Istio also provides the same capability. In this talk, we will have a look at how Istio and Hystrix implement the Circuit Breaker pattern, and what pros/cons each of them has.

Good Enough for the Finance Industry: Achieving High Security with Containers and Microservices

Security is a challenge for most companies. Especially those in periods of rapid growth. It is often taken for granted as we trust the frameworks we use to implement the necessary security protocols for us. However, one only needs to pick up the paper to find out that this simply isn't true. Information security is now a chief concern of many small and mid-size companies as well. We'll show you how we use AWS, Calico, OWASP Dependency Checker, CoreOS’s Clair, and Notary to achieve reliable observable security at the code level, container level, cluster level, and even the AWS account level to maintain the Gold Standard of security (authentication, authorization, and auditing.) We will focus on the security mindset and the specific implementation we have at Ygrene to keep data secure.

Automatically TUF about Container Image Security in Kubernetes

The Update Framework (and its sister project from the CNCF, Notary) are a little known gems in the cloud native community. These projects are however extremely vital for making rigorous guarantees about the contents of your software package (read container image) when it is deployed into an environment like Kubernetes. We'll demystify TUF/Notary at the beginning of this talk, and then do a demonstration for setting up image signing through your build pipeline finally ending in Kubernetes where we will restrict the container images that can be deployed to just ones signed by us (using Validating/Mutating Admission Webhook Controllers.) Our goal is to empower you to take the skills you learn from the talk and implement a similar process in your own CI/CD pipeline.

Trust is good, control is better - A (short) story about Network Policies

Probably everybody who uses Kubernetes in a productive environment with multiple users possibly has looked at policies. Often the operators of the cluster(s) just trust the policies but in some cases it might be useful to control if the policies actually have taken action and often there are just to many Policies in the cluster setup to manually test them all (and obviously you don’t want to do this). Testing the effectiveness of the Network Policies can be done in different approaches. In this talk we will show you the benefits and drawbacks of different approaches and what solution we finally chose. Also we will show you some other tools and how they complement our solution. As a takeaway you will get an overview of different testing strategies for policies, as well as understanding challenges in testing policies in general and the Kubernetes ecosystem.

Secure but flexible - Cloud Native Continuous Delivery in the Finance industry

The story of transitioning a large financial company to practice Continuous Delivery on top of Openshift using only open source solutions. Cloud Native is new and rapidly evolving, which makes enterprise clients anxious -- so they jump to large, monolithic vendor solutions in search of an automatic “right answer.” These solutions can be over complicated and rigid, ultimately stifling innovation. This financial institution needed a system flexible enough to support about fifty development teams independently deploying microservices while enforcing strict security and compliance requirements. Using open source tools we were able to give our client exactly the security and flexibility they needed, without locking them into a one size fits all solution. Our solution is built using the Gitops pattern, Jenkins, Docker and Openshift/Kubernetes - all open tools which can be used at any other company. I will explain the design decisions, the technical solution and the challenges of onboarding development teams to the new platform.

Service Mesh Magic for Managed Kubernetes

A service mesh adds new qualities to your container orchestration: It connects, secures, observes and controls service invocations in a language agnostic way that doesn't require any code changes. This presentation starts with a gentle intro to service meshes. Starting with the shortcomings of Docker and Kubernetes. I will show in a live demo how a service mesh implements cross cutting concerns like traffic shifting, blue/green deployments, and observability. We then have a look at how a service mesh bridges to the world of chaos engineering by giving us the possibility to inject errors at a certain rate. As a practical example I will use Envoy with Istio and AWS App Mesh. To conclude I will critically analyze if and how a service mesh should evolve into becoming a standard component of a managed container service.

TestContainers + JUnit5 = elegant end-to-end tests for microservices

This talk suggests to perform automatic testing of the release candidate against other real services started in Docker. TestContainers library facilitates simple start up of services and their dependencies, i.e. (No)SQL databases in containers. The lib has a list of valuable features which significantly simplify a developer’s life. In the demo part a simplified version of a SMS platform is emulated. Apart from Spring Cloud Eureka there are 3 more business services built on Spring Boot. One of them is Acceptor which accepts clients requests, consults Billing on a decision whether to proceed with a request or not. Eventually Sender does an actual submit of an SMS to a mobile operator. Later the operator pushes a delivery report to Sender’s endpoint which should be matched to the submitted message and forwarded to Acceptor and then to client.

6 weeks to migrate!

Few months ago I met a team: 8 developers working on a B2C app of car renting. They were tired, so tired ... Their vagrant was slow, the server crashed two or three times a week without restarting and without any logs, a roll out to production took 2 days to be tested, by hand ... Together we decided to react, let's have the Roll's Royce of the development environnement! Thus I've dockerized the app, I've created a Kubernetes cluster, I've added Spinnaker to the loop and some other stuff. We had some up and down, some smile and tear, but we finally did it and we have no regret. That what's I want to tell you with all the thing we learned along the way.

Caught in the Hype Cycle? - How to make cloud native transformation a success

Platforms such as Kubernetes offer huge benefits in terms of reducing operations efforts and encapsulating complexity. Due to this attractiveness, we built up a large-scale Kubernetes cluster to be used for our public and internal services. However with every new cloud native service deployed we found a new obstacle preventing it from going live. So we had to solve a number of unexpected challenges. In particular coupling cloud native services to the large existing application landscape turned out to be difficult. Also moving artifacts into the container platform comes with challenges. Consequently in the first 12 months we only moved very few services as many users were disillusioned. We iteratively identified the obstacles - technical and cultural - and developed strategies to resolve them. This presentation will discuss them and help you guide your project to success.

A Hitchhiker's Guide to Cloud Native API Gateways

Good APIs are the center piece of any successful digital product and cloud native application architecture. But for complex systems with many API consumers the proper management of these APIs is of utmost importance. The API gateway pattern is well established to handle and enforce concerns like routing, versioning, rate limiting, access control, diagnosability or service catalogs in a microservice architecture. So this session will have a closer look at the cloud native API gateway ecosystem: Ambassador, Gloo, Kong, Tyc, KrakenD, et.al. But which one of these is the right one to use in your next project? Let's find out. Leander will start off by briefly explaining the API gateway pattern and derive a simple criteria catalog. He will then continue by comparing and showcasing the most promising ones.

Enterprise Cloud native is The New Normal

The world of IT and technology is moving faster than ever before. Cloud native technology and application architecture have been influencing and disrupting the software engineering discipline for the past years and there is no end in sight. But according to Gardner we are currently entering the trough of disillusionment. So does this mean we followed the wrong path and that we should turn back? Hell no!!! Despite of all disbelievers and trolls: cloud native is neither a failure nor a hype anymore! It will become mainstream. We already see widespread adoption at all our customers. Of course there still is a lot of room for improvement. No doubt about that. Technology, methodology, processes, operations, cloud native architecture and software development need to mature even further to become boring and ready for the enterprise. This is software industrialization in its purest form. And our skills and expertise are required to make this happen.

Kubernetes Day 3- The State of Kubernetes Development Tooling

With Kubernetes emerging as the de facto standard for service orchestration, discussion is shifting from 'How does Kubernetes work?' to more specific concerns such as 'How do I achieve an optimal development workflow?' The answer lies in finding combinations of tools that work together in synergy. They should produce end to end workflows that perform effectively in the real world, while also covering a wide range of development stages—building, deploying, debugging, and so on. Goal in mind, let's dive into the tooling available in the current landscape—tools such as Helm, Draft, Skaffold, Forge, Telepresence, Garden, and Tilt. We'll map their capabilities to developer needs, then outline workflows developers can use in practice right away.

Brand new for 2019, this is the workshop to attend if you want to harden your Kubernetes clusters, configure a service mesh, securely deploy internal and external workloads and implement security metrics and observability to catch malicious behaviour in the act. Each attendee will have a GKE cluster and a microservices-based web app deployed into it. Attackers have compromised your app and are mining cryptocurrency on your public cloud bill. Your job is to identify how they got in, get them out and keep them out. You will install and configure a range of native Kubernetes security features and cloud native tools including Istio, OpenTracing, Elasticsearch, Prometheus, Weave Flux and more as we power through this intensive, hands-on workshop.

How to run a JupyterHub on Kubernetes

One of the most popular tools among data scientists are Jupyter Notebooks. The open source web application provides an environment to document and execute code, inspect the results and visualize data without leaving the environment. We show, how Docker and kubernetes enable the deployment of a pre-configured data science environment, the so-called JupyterHub. The shared resources of the multi-user version of the notebooks can be managed efficiently by kubernetes. This makes it easy for business analysts and data scientist to access computational environments and resources in the cloud without having to worry about dependency management, installation and maintenance tasks. #kubernetes #jupyterhub #datascience

What does the kubelet say?

Etcd goes 'store', kube-proxy goes 'route', API server goes '418', what does the kubelet say? Kubelet is one of the central components in the kubernetes cluster. Most of us are taking it for granted that is would just work and start our containers. CNI handles the networking part, kube-proxy the service part, but kubelet does more than just starting containers. In this talk, I cover kubelet on a high level before deep diving in the belly of the beast and its interfacing with CNI, container runtime and ultimately Linux kernel.

Secure Software on Azure Kubernetes Services

By applying some essential security measures, you can make your Azure Kubernetes Service solution a much harder target for hackers. But how do you do that, while still deploying to production multiple times a day? You can do this by embedding application security into your development process. For example, you model threats your application may face and add countermeasures up front. And inside the delivery pipeline, you monitor your repository for vulnerabilities. But there's more! In this talk I'll show you what you need to know.

Creating Platform Agnostic Packages that Can Run Anywhere

One of the dreams of development is to build a software package once, then be able to deploy it anywhere. With current Open Source projects, this dream is closer than ever. In this session, you will learn how to create software packages that run almost anywhere. You will see how the same application can be run on bare metal, on a VM or in a container — with everything needed to automate that application already built into the package itself. This even works with a mixed infrastructure - metal for your static compute heavy loads, VMs for your persistent data stores and ephemeral short-lived containers for your applications that are managed by Kubernetes or other container scheduling services. You’ll also learn how to build and deploy these packages with the intelligence to self-organize into topologies, with no central orchestrator needed. Learn how the dream of platform agnostic and self-organizing packages is fulfilled today and how it will evolve in the future.

Managing large scale networks using Salt and Docker

Network automation: there’s more to it than just configuration management - it’s a perfect opportunity for event-driven infrastructure. Numbers speak for themselves: the network has never been that stable before. But this comes with a complexity cost, which is what we’ll analyse in this talk. Cloudflare runs one of the largest and the best connected global networks. Thanks to a variety of advantages, including scalability and flexibility, we chose Salt as the principal tool to manage our network infrastructure. The price paid for these advantages is the management complexity: one Salt Proxy Minion process is required for each network device managed. As our fleet consists on over a thousand network devices (and growing), we therefore need to manage thousands of process, distributed globally. Additionally, the architecture requires one or more Salt Master processes. Due to scalability and redundancy reasons, we have deployed over 100 Salt Masters. Using Docker we have managed to nicely scale this entire conglomerate and prepare the environment for future growth.

Container Isolation Approaches for Multi-Tenant Container Workloads and Serverless Computing

Container virtualization has become the tool of choice for running isolated applications in cloud environments. Linux-Containers virtualize at the operating system level, with multiple containers running atop the operating system kernel directly. Therefore, threats to one container are potentially threats to many others. Especially for PaaS and Serverless providers, the secure execution of untrusted workloads on their platform in order to mitigate software vulnerabilities from spreading has high priority. Containers face a variety of different threats, vulnerabilities and historical weaknesses that need to be considered and defended against. In this talk we will look at different approaches for securing container workloads. gVisor, Kata Containers, Nabla Containers and Firecracker are presented and compared with each other.
