Putting The PaaS in OpenStack with Diane Mueller @RedHat OpenShift Origin
RedHat has created it's own OpenStack distribution that is now in preview and still a bit rough around the edges, but promises to include what is needed to deploy & evaluate a truly & complete Open Cloud environment. In addition, Red Hat wants there to be a widely used open-source community developed PaaS model for the cloud which includes being open to participation by a community of peers.
To really create a open cloud environment and to make it useful, you need to complete the stack with an PaaS. Just getting a cloud environment up and running is no longer enough. The challenge that OpenStack faces is how to get people, applications and services working on OpenStack out of the box.
One approach to the problem is to combining all the necessary pieces that go into building an OpenStack cloud (compute, storage, networking, management) with a platform as a service (PaaS) into your OpenStack distribution.
OpenShift Origin project is licensed under the Apache License 2.0, a permissive and widely-used open source license, which was selected so that the code would be available for use by the broadest range of
individuals and organizations. This is the same license chosen by the OpenStack project, for much the same reason. This license is already well known and understood by individuals and organizations already involved in cloud computing and in enterprise scale open source development.
In this session, I'll discuss RedHat's efforts with OpenStack, Fedora, & OpenShift Origin to create a more complete OpenStack distribution. Our community initiatives to ensure Origin easily and seamlessly integrates on any OpenStack distribution and how to you can add Origin into your own OpenStack distributions.

OpenStack in an Ever Expanding World of Possibilities - Vancouver 2015 SummitLew Tucker
Over the past several years we have seen the continued adoption of OpenStack and it’s expansion into new areas: from cloud service providers, enterprise private clouds to large media companies, telecommunication giants, and big science. At the same time, open source based platforms for network functions virtualization (NFV) are fueling a movement toward cloud computing in almost all major telco’s.
In the developer world, open source projects, such as Docker, Mesos, Kubernetes, and Spark are gaining a lot of attention and being integrated into OpenStack through projects Kolla and Magnum.
This session will cover how these projects and activities relate to each other and further expand the utility and adoption OpenStack.
This is an Introductory presentation about Docker and Openstack, where they come together. This also give details about community projects in this area (Docker + Openstack) and more details about Nova-Docker. It assumes background of both Dockers and Openstack in general.
Presentation give at the Melbourne Docker Meetup on container related projects within OpenStack. Specifically looking at Project Magnum and Project Kolla and how they are leveraging technologies like Docker, Kubernetes and Atomic.

Episode 02 of "OpenShift in a nutshell" presentations in Iran OpenStack community group
This episode is about different layers, architecture, security in OpenShift.
I hope you will find it useful.
In addition to authorization policies that control what a user can do, OpenShift Container Platform gives its administrators the ability to manage a set of security context constraints (SCCs) for limiting pods and securing their cluster.
Default security context may be too restrictive for containers pulled down from DockerHub, thorugh this talk we'll explore the various steps to execute for enabling required permissions on selected OpenShift's pods.
The primary requirements for OpenStack based clouds (public, private or hybrid) is that they must be massively scalable and highly available. There are a number of interrelated concepts which make the understanding and implementation of HA complex. The potential for not implementing HA correctly would be disastrous.
This session was presented at the OpenStack Meetup in Boston Feb 2014. We discussed interrelated concepts as a basis for implementing HA and examples of HA for MySQL, Rabbit MQ and the OpenStack APIs primarily using Keepalived, VRRP and HAProxy which will reinforce the concepts and show how to connect the dots.

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. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery.

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.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

OpenShift Infrastructure
●
Within OpenShift, Kubernetes manages containerized applications across a
set of containers or hosts and provides mechanisms for deployment,
maintenance, and application-scaling.
●
Docker packages, instantiates, and runs containerized applications.
6. IRAN Community| OpenStack.ir
OpenShift Infrastructure
A Kubernetes cluster consists of one or more masters and a set of nodes.
You can optionally configure your masters for high availability (HA) to ensure that
the cluster has no single point of failure.
8. IRAN Community| OpenStack.ir
The master manages nodes in its Kubernetes cluster and schedules pods to
run on nodes.
The master is the host or hosts that contain the master components, including
the API server, controller manager server, and etcd.
OpenShift Infrastructure
10. IRAN Community| OpenStack.ir
API Server
The Kubernetes API server validates and configures the data for pods, services,
and replication controllers. It also assigns pods to nodes and synchronizes pod
information with service configuration.
API Server Can be run as a standalone process.
OpenShift Infrastructure

https://docs.openshift.org/latest/rest_api/kubernetes_v1.html
More details:
12. IRAN Community| OpenStack.ir
etcd
etcd stores the persistent master state while other components watch etcd for
changes to bring themselves into the desired state. etcd can be optionally
configured for high availability, typically deployed with 2n+1 peer services.
OpenShift Infrastructure
13. IRAN Community| OpenStack.ir
Controller Manager Server
The controller manager server watches etcd for changes to replication controller
objects and then uses the API to enforce the desired state. Can be run as a
standalone process. Several such processes create a cluster with one active leader
at a time.
OpenShift Infrastructure
14. IRAN Community| OpenStack.ir
Virtual IP
Optional, used when configuring highly-available masters with the pacemaker
method. There is one virtual IP (VIP) and it is managed by Pacemaker.
The VIP is the single point of contact, but not a single point of failure, for all
OpenShift clients that:
●
cannot be configured with all master service endpoints, or
●
do not know how to load balance across multiple masters nor retry failed master
service connections.
OpenShift Infrastructure
15. IRAN Community| OpenStack.ir
Pacemaker
Optional, used when configuring highly-available masters with the pacemaker
method.
Pacemaker is the core technology of the High Availability Add-on for Red Hat
Enterprise Linux, providing consensus, fencing, and service management. It can be
run on all master hosts to ensure that all active-passive components have one
instance running. Pacemaker is also available in CentOS 7 and Fedora.
Another option is to use HAProxy load balancer to switch between API endpoints.
OpenShift Infrastructure
16. IRAN Community| OpenStack.ir
HAProxy
Optional, used when configuring highly-available masters with the native method to
balance load between API master endpoints.
The advanced installation method can configure HAProxy for you with the native
method. Alternatively, you can use the native method but pre-configure your own
load balancer of choice, or use the pacemaker HA method instead.
OpenShift Infrastructure
18. IRAN Community| OpenStack.ir
OpenShift Infrastructure
While in a single master configuration, the availability of running applications
remains if the master or any of its services fail. However, failure of master services
reduces the ability of the system to respond to application failures or creation of
new applications. You can optionally configure your masters for high availability
(HA) to ensure that the cluster has no single point of failure.
19. IRAN Community| OpenStack.ir
OpenShift Infrastructure
Runbook:
A runbook entry should be created for reconstructing the master. A runbook entry
is a necessary backstop for any highly-available service. Additional solutions merely
control the frequency that the runbook must be consulted. For example, a cold
standby of the master host can adequately fulfill SLAs that require no more than
minutes of downtime for creation of new applications or recovery of failed
application components.
20. IRAN Community| OpenStack.ir
OpenShift Infrastructure
Use a high availability solution to configure your masters and ensure that the
cluster has no single point of failure. The advanced installation method provides
specific examples using either the native or pacemaker HA method, configuring
