Inside Architecture of Neutronmarkmcclain

- Neutron provides network abstraction and connectivity as a service for OpenStack. It uses a pluggable architecture with separate components for networking services like L2, L3, VPN, firewall, and load balancing. - The Neutron server exposes a REST API and uses plugins to interface with networking devices and agents. L2 agents connect virtual ports and isolate tenant traffic. L3 agents route between networks using Linux network namespaces. - When a VM boots, Neutron creates a port, notifies the DHCP agent, wires the port, and boots the instance while isolating network resources for each tenant. Additional services like load balancing are implemented through plugins and dedicated agents.

Key aspects covered include using RabbitMQ clusters with mirrored queues for high availability, deploying Neutron on separate networking nodes, and using a Percona MySQL cluster to provide synchronous replication, data consistency, parallel applying and atomic node provisioning. The goal is an OpenStack architecture that is highly available, reliable, and can recover automatically from faults.

High Availability for OpenStackKamesh Pemmaraju

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.

"Lightweight Virtualization with Linux Containers and Docker". Jerome Petazzo...Yandex

Lightweight virtualization", also called "OS-level virtualization", is not new. On Linux it evolved from VServer to OpenVZ, and, more recently, to Linux Containers (LXC). It is not Linux-specific; on FreeBSD it's called "Jails", while on Solaris it’s "Zones". Some of those have been available for a decade and are widely used to provide VPS (Virtual Private Servers), cheaper alternatives to virtual machines or physical servers. But containers have other purposes and are increasingly popular as the core components of public and private Platform-as-a-Service (PAAS), among others. Just like a virtual machine, a Linux Container can run (almost) anywhere. But containers have many advantages over VMs: they are lightweight and easier to manage. After operating a large-scale PAAS for a few years, dotCloud realized that with those advantages, containers could become the perfect format for software delivery, since that is how dotCloud delivers from their build system to their hosts. To make it happen everywhere, dotCloud open-sourced Docker, the next generation of the containers engine powering its PAAS. Docker has been extremely successful so far, being adopted by many projects in various fields: PAAS, of course, but also continuous integration, testing, and more.

Lightweight Virtualization with Linux Containers and Docker I YaC 2013Docker, Inc.

Why open stack database as a service offerings are doomedopenstackindia

The document discusses two Database as a Service (DBaaS) offerings in OpenStack: Trove and MagnetoDB. Trove aims to provide relational databases but suffers from a large feature gap compared to other DBaaS providers and lacks a clear plan for scalability and availability across its supported databases. MagnetoDB aims to provide a key-value API but its use of multiple backends prevents a unified approach to scalability and availability. The document argues both offerings are flawed and doomed unless their scopes are narrowed.

How analogue intelligence complements AIPaul Rowe

Artificial Intelligence is providing benefits in many areas of work within the heritage sector, from image analysis, to ideas generation, and new research tools. However, it is more critical than ever for people, with analogue intelligence, to ensure the integrity and ethical use of AI. Including real people can improve the use of AI by identifying potential biases, cross-checking results, refining workflows, and providing contextual relevance to AI-driven results. News about the impact of AI often paints a rosy picture. In practice, there are many potential pitfalls. This presentation discusses these issues and looks at the role of analogue intelligence and analogue interfaces in providing the best results to our audiences. How do we deal with factually incorrect results? How do we get content generated that better reflects the diversity of our communities? What roles are there for physical, in-person experiences in the digital world?

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.
