The document discusses the infrastructure challenges faced by Edison Nation, an old Rails 2.3 application with over 100,000 members and a distributed team. It covered topics like moving to newer Linux distributions, improving automation, upgrading Rails, implementing load balancing, and switching to Unicorn and Nginx for better performance under heavy load after the site was featured unexpectedly on Nightline TV. It also discussed using Puppet for configuration management, MCollective for orchestration, Graylog2 for log management, and other techniques for scaling the infrastructure.
Oscon 2012 : From Datacenter to the Cloud - Featuring Xen and XCPThe Linux Foundation
Do you dream of being able to spin up ten or twenty (or a thousand) virtual machines in an instant? Discover and repair resource bottlenecks without moving a finger? Dodge the loss of an entire storage array with no-one noticing? Span across data centers with a fleet of virtual machines? This is no sales pitch; during this tutorial, we’ll demonstrate how to leverage truly FOSS tools to build a powerful, scalable cloud that easily competes with those proprietary solutions!
This deep-dive into Xen, Xen Cloud Platform, and other FOSS cloud tools and concepts is intended both for those ready to wholeheartedly embrace virtualization and for those already seasoned in general virtualization practices. You’ll leave with a collection of pre-made tools that you can use right out of the box or modify to your liking. You’ll also leave with immediately useful knowledge on best practices and common pitfalls, presented by actual FOSS practitioners like you.
We begin this tutorial by discussing Xen, Xen Cloud Platform (XCP), and XCP cloud concepts (pools, hosts, storage, networks, etc.). We then explore in detail the API that makes Xen so useful for building a cloud, explore provisioning of hosts and guests using PXE, and discuss templating and installing guest virtual machines. Critical to understanding potential bottlenecks, identifying tuning opportunities and planning for the future, we will discuss performance monitoring and methodologies. Next, we teach you how to make the most of your new FOSS cloud capabilities and discuss in detail high availability infrastructure for storage and networking, advanced networking capabilities like bonding/VLANs, and the cloud orchestration tools that save you time and money. All of this with a focus on XCP in enterprise environments. Tools discussed include DRBD, Pacemaker, Open vSwitch, Cloudstack, Openstack, and more.
We conclude by shedding light on exciting developments: Xen 4.2 has recently been released, with just over a year of development time and nearly 3,000 changesets. We will discuss many of the new features introduced in 4.2, as well as what changes we have in store for the 4.3 release as well as other exciting developments.
Sergey Dzyuban "To Build My Own Cloud with Blackjack…"Fwdays
Cloud providers like Amazon or Google have a great user experience to create and manage PaaS. But is it possible to reproduce the same experience and flexibility locally, in the on-premise datacenter? What if your own infrastructure grows to fast and your team can’t deal with it in the old way? What does Jenkins, .NET microservices and TVs for daily meetings have in common?
This talk shares our experience using DC/OS (datacenter operating system) for building flexible and stable infrastructure. I will show the evolution of private cloud from the first steps with Vagrant to the hybrid cloud with instance groups in Google Cloud, the benefits it gives us and the problems we get instead.
In this talk, Damien describes the infrastructure Nuxeo has built around Docker containers, which is mainly based on CoreOS and Docker, and how it provides a way to generically run applications not only on a single host, but across a whole cluster of hosts. The resulting architecture can be used to implement a PaaS approach for any application.
Xen, XenServer, and XAPI: What’s the Difference?-XPUS13 Bulpin,PavlicekThe Linux Foundation
Many people have difficulty understanding the difference between the Xen Hypervisor, XenServer, and XAPI. In this session, James Bulpin, Director of Technology for XenServer, and Russell Pavlicek, Evangelist for the Xen Project, will attempt to clarify what each project is, what it does, and how it compares with the others. We will cover some of the basic features and functions, the tasks for which each is suitable, and where the projects overlap. Attendees will come away with a better sense of where these three projects fit in the world of Xen virtualization.

The Xen Hypervisor was built for the Cloud from the outset: when Xen was designed, we anticipated a world, which today is known as cloud computing. Today, Xen powers the largest clouds in production.
This talk explores success criteria, architecture, trade-offs and challenges for cloudy hypervisors. It is intended for users and developers and starts with a brief introduction to Xen and XCP, their architecture and on common challenges for KVM and Xen.
I will introduce the concept of domain disaggregation as an approach to increase security, robustness and scalability: all important factors for building clouds at scale and show how advanced security features suchas Xen Security Modules and SELinux can help secure your cloud further.
The talk will conclude with exciting developments in the Xen community, such as Xen for ARM servers, a new virtualization mode for Xen, running applications without OS in a Xen guest and point out their implications for building open source clouds.
Rackspace has years of experience with running Xen at scale, starting with Xen and migrating to XenServer. We will share why we use Xen/XenServer along with some of the issues that we've experienced. We will touch on our experience with migrating from Xen to XenServer and the challenges there. We will share information about Rackspace Cloud Servers architecture, and touch briefly on OpenStack when doing so. We will explain how we use Xen to quickly deploy new Openstack services with what we call Nova on Nova. And finally, we will discuss what additional features and improvements are needed and why.
The Xen 4.3 release we will experiment with a roadmap: an informal set of features and changes that we as a community will be aiming at for the 4.3 release. The roadmap is flexible, but will be used as a guide to coordinate our efforts, as well as a benchmark to let us know when 4.3 will be ready to release.

First, we will examine interesting features of XAPI, such as events, pools etc. that allow easy administration of virtualized environment. Then, we will see how these features fit into the Xen Orchestra architecture, which has been completely redesigned to reduce connections, bandwidth waste, storing of structured data, allowing persistence and so on. Finally, we will show how we display all that information (ergonomics choices from an ergonomist). We will conclude quickly on how you can engage and contribute to the Xen Orchestra project and make sure it helps fulfil your needs.

Leonid Vasilyev "Building, deploying and running production code at Dropbox"IT Event
Reproducible builds, fast and safe deployment process together with self-healing services form the basis of stable and maintainable infrastructure. In this talk I’d like to cover, from the Site Reliability Engineering (SRE) perspective, how Dropbox addresses above challenges, what technologies are used and what lessons were learnt during implementation process.
Cloud providers like Amazon or Goggle have great user experience to create and manage PaaS and IaaS services. But is it possible to reproduce same experience and flexibility locally, in on premise datacenter? This talk describes success story of creation private cloud based on DC/OS cluster. It is used to host and share different services like hadoop or kafka for development teams, dynamically manage services and resource pools with GKE integration.
Why Kubernetes as a container orchestrator is a right choice for running spar...DataWorks Summit
Building and deploying an analytic service on Cloud is a challenge. A bigger challenge is to maintain the service. In a world where users are gravitating towards a model where cluster instances are to be provisioned on the fly, in order for these to be used for analytics or other purposes, and then to have these cluster instances shut down when the jobs get done, the relevance of containers and container orchestration is more important than ever.
Container orchestrators like Kubernetes can be used to deploy and distribute modules quickly, easily, and reliably. 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. We will discuss how we have replaced our home grown container orchestrator with Kubernetes which used to manage the container lifecycle and manage resources in accordance to our requirements. We will also discuss the feature list as container orchestrator which is helping us deploy and patch 1000s of containers and also a list which we believe need improvement or can be enhanced in a container orchestrator.

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.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

• Less complexity managing certificates
and Nginx configs
