The document discusses Kubernetes and containers. It begins by introducing Kubernetes as the future of operations. It then covers containers, what they are compared to VMs, and how cgroups and namespaces provide isolation. It discusses how containers are managed through schedulers, what problems schedulers solve like provisioning apps across servers and handling node failures. It concludes with a demo and Q&A around these concepts.
OTP20 officially introduced dirty schedulers. In this talk, we'll cover why they're part of OTP and what function they perform. Using Rust NIFs, we'll compare schedulers and dirty schedulers to illustrate the trade-offs between scheduler types. By the talk's end, it should be apparent why dirty schedulers are part of OTP and how and when you should consider using them.

Centralizing Kubernetes Management in Restrictive EnvironmentsKublr
While developers see and realize the benefits of Kubernetes, how it improves efficiencies, saves time, and enables focus on the unique business requirements of each project; InfoSec, infrastructure, and software operations teams still face challenges when managing a new set of tools and technologies, and integrating them into existing enterprise infrastructure.
This is especially true for environments where security and governance requirements are so strict as to come into conflict with the cloud-native reference architectures.
During his presentation, Oleg will outline a plan that leverages open source cloud-native technologies while meeting enterprise security and governance requirements. He’ll summarize common prerequisites for running Kubernetes in production, and how to leverage fine-grained controls and separation of responsibilities to meet enterprise governance and security needs; what’s needed for a general architecture of a centralized Kubernetes operations layer based on open source components such as Prometheus, Grafana, ELK Stack, Keycloak, etc.
The presentation will cover basic requirements for audit, security, authentication, authorization, integration with existing identity management, logging, and monitoring. Additionally, the audience will learn whether cloud-hosted Kubernetes cover these requirements, how to integrate a compliant Kubernetes installation with their existing cloud infrastructure, the limitations of a bare-metal installation, interactions with vSphere’s API, achieving HA, reliability and disaster recovery, as well as handling OS upgrades, security patches, and Kubernetes upgrades.
Kubernetes in Highly Restrictive EnvironmentsKublr
Installing Kubernetes is easy. Ensuring it complies with your organization’s enterprise governance and security requirements isn’t.
How do you use the technologies while meeting enterprise security requirements? We'll summarize common prerequisites for running Kubernetes in production, and how to leverage fine-grained controls and separation of responsibilities to meet enterprise governance and security needs.
This deck includes basic requirements for audit, security, authentication, authorization, integration with existing identity broker, logging, and monitoring. Additionally, we'll go into whether cloud-hosted Kubernetes cover these requirements, how to integrate a compliant Kubernetes installation with their existing cloud infrastructure and how to handle cross-team communication (network/compute/storage/security).
Since on-premise Kubernetes deployments have their challenges, limitations of a bare-metal installation, interactions with vSphere’s API, achieving HA, reliability and disaster recovery, as well as handling OS upgrades, security patches, and Kubernetes upgrades are also considered.
In 2014, users simply expect more from web apps, developers expect less complexity.

Interop 2018 - Understanding Kubernetes - Brian GracelyBrian Gracely
In the world of containers, Kubernetes has emerged as the dominant standard for managing how containers are deployed, monitored and managed. This talk will provide fundamental knowledge of how Kubernetes interacts with containers, storage, networking, security and application frameworks. The audience will learn about the core element of Kubernetes, including etcd, the Kubernetes API, the various types of controllers, and the Kubelet. In addition, we'll discuss the broad ecosystem of projects and technologies that make Kubernetes usable within the Enterprise, and across multiple cloud environments.
We’ve been told the future is automated, orchestrated, service-oriented applications built on top of dynamic, on-demand, massively scalable infrastructure (serverless anyone?). But how do you go from here to there? At Betterment we built a platform that goes beyond “lift and shift”. In this presentation, I’ll share how we built a platform for tomorrow, with support for today’s legacy apps. I’ll also share how we designed the tooling to encourage developers to build for the future, while ensuring security and reliability, going deep into how the tooling ultimately guided our own path, and why the principles behind everything helped us stay the course.
Ever wondered about the new Cloud offerings out there? What is a PaaS? What is this thing called OpenShift?
Whether your business is running on applications based on Java EE6, PHP or Ruby, the cloud is turning out to be the perfect environment for developing your business. There are plenty of clouds and platform-as-a-services to choose from, but where to start?
Join us for an action-packed hour of power where we'll show you how to deploy your existing application written in the language of your choice - Java, Ruby, PHP, Perl or Python, with the framework of your choice - EE6, CDI, Seam, Spring, Zend, Cake, Rails, Sinatra, PerlDancer or Django to the OpenShift PaaS in just minutes. All this and without having to rewrite your app to get it to work the way the cloud provider thinks your app should work.
You can have your business applications running in the cloud on OpenShift Express in seconds, while also making use of the web browser do the heavy-lifting of provisioning clusters, deploying, monitoring and auto-scaling apps in OpenShift Flex.
If you want to learn about OpenShift PaaS and see how investing 45 mins of your time can change everything you thought you knew about putting your business applications in the cloud, this session is for you!
Muita tecnologia, novas ferramentas para cuidar, novos processos, ajustes e uma penca de alteração na forma de desenvolver, entregar e operar software. Muito se fala em se preocupar mais com cultura, mas o que realmente devemos nos preocupar na adoção? Quais os problemas enfrentados nas grandes organizações que deixa o desafio ainda maior. Será que as empresas estão preparadas para a adoção? O fato é que a maioria das empresas não estão preparadas para a adoção de DevOps em seus times. Nessa talk vou falar sobre isso e outras coisas mais, que vão além do PPT e do Blog. Coisas que talvez ninguém te contou.
(java2days) Is the Future of Java Cloudy?Steve Poole
Java – it’s on billions of devices. We think it powers the world. Others disagree.
In this talk we’ll examine a few of the reasons why some developers believe Java is being left behind by younger (or at least different) programming languages. We’ll show where the claims make sense and debunk some of the more outrageous slander. We know the future of Java includes a more polyglot world so we’ll help you understand with practical advice where Java shines today and where you might be better using something else. We’ll also cover the challenges that all runtimes have in the new era of Cloud and how the Java community is leading the way in evolving Java into becoming the Cloud runtime of choice.
This talk will help you become more informed when dealing with those inevitable language cage fights around the water cooler. You’ll be able to refute the fake news and replace it with clear facts. Vote for Java – you know it makes sense

DCSF19 How To Build Your Containerization Strategy Docker, Inc.
Lee Namba, Docker
The Docker Enterprise container platform helps organizations deploy and manage applications faster and it secures the application pipeline at a lower cost than traditional application delivery models. But it takes more than just great technology to achieve the desired results. The organization and culture of your enterprise directly impacts what you transform, how it’s done, and who does it. Success requires a strategy for how you will govern the container platform environment, how to assess your application estate, what your delivery pipeline will look like, and how to ensure developers, operators, security teams and others play nicely together. In this talk I will cover topics such as different types of workloads (legacy, microservices, FaaS, big data and more), how your org chart can influence whether you deploy CaaS (Containers as a Service) vs CLaaS (Clusters as a Service), how "shifting left" can determine if you can outsource, centralized vs distributed CI/CD and how containers play a role, transforming your pets into cattle, how giant whale balloons are used for onboarding, and a prescriptive and comprehensive methodology for successfully deploying containers into your enterprise.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

49. What Schedulers Solve
• Provision second app X server
• Node X needs more RAM
• Set up mounts on node
• Set up a new environment
• Node is down, bring app back up
We are here to talk about containers, but we're more here to talk about process and the type of workflows that containers enable.
Before we talk about tomorrow, let's talk about today.
especially in terms of deployments and outages
Today, Let's say Dev Team A adds new functionality to an application.
Today Dev asks ops
some kind of puppet configuration change
and ops installs the library
Except that it was the wrong one.
so we gotta start all over again
But also, Dev Team B also needs another library, which is similar to Dev Team A, but just a bit different, so don't confuse the two or production will light on fire.
But wait, Dev team C has a Blocker request for another application requirement.
<maybe> And all these requirement declarations are managed in the same puppet codebase, and conflicts can occur.</maybe>
Which potato is hottest? who knows.
These delays are just a natural outcome of what happens when complex communication has to happen between two Departments.
The question is how to simplify that communication.
to reduce operational overhead
But before we can make this process simpler, we need to reassess our idea of what an App actually is.
Pages
And sit up all night and try to figure out away to make the best out a shit situation
And the reason for many of those pages
Is that the app has a relationship with a particular node
A very special relationshp, so we have to be worried about the node,
because if it goes away
the app gets sad
then it gets angry.
and engages in all kinds of self destructive behaviour
When maybe the problem was that it was in such a closely coupled relationship in the first place
Maybe App just needed a little more space.
But before we can make this process simpler, we need to reassess our idea of what an App actually is.
is it the code?
well without the runtime or interpreter, nothing's going to happen.
So maybe the app is the code and runtime?
But sometimes the run time and development libraries have system dependencies that have to be configured and installed.
So the app is a combination of all these things.
Especially since if any of these components change, application behavior can change.
But we're managing the app like this
Which necessitates communication like this
But if we treat the app as one holistic unit
And we use containers to manage them
Then we're ready to talk about tomorrow.
Containers encapsulate the application and all of its dependencies in the form of a portable artifact. It's the most repeatable way to build and deploy an application, and minimizes surprises by trying to manage these dependencies separately.
Containers are basically a way to encapsulate the code and depdencies in a repeatable fashion
instead of the "app" being a jar file or a python egg, the app is now the container, which lets you repeat the combo of app+runtime+system config/libs
Bless Docker’s heart, but Containers are NOT better VMs, they’re not any sort of virtual anything.
They're just processes.
But they're isolated processes.
Containers are based on two technologies
Now all this sounds new and scary, but what if I told you that these kernel features were merged into the linux kernel in 2008, and by default you’re using some of these features today.
Here's a production machine running httpd.
Notice that it's already using a namespace!
If we look at another process , it's in the same name space. The same container.
And is that really smart? running all our apps and processes in the same namespace on the same machine?
So the question is:
Whether or not we want to take advantage of what the linux kernel is already doing for us?
same bad patterns
constant catrastophes
haphazard processes that require human intervention and don't scale.
For that you need a scheduler.
what schedulers do is elegantly solve these types of problems
well, we all know what containers look like. everyone's heard of docker
but what's a scheduler look like.
Well, up till today, a scheduler looks like this.
But today, a scheduler looks like this.
Kubernetes is basicaly a lessons-learned project from google's last few years managing containers internally.
But unlike those internal projects, this is open source, and free.
