Virtualisation is a technology that abstracts ICT services from underlying hardware, allowing more efficient use. Server virtualisation in particular allows organisations to increase physical server efficiency from 30% to over 80% usage on average, reducing server needs by 30%, and quickly provision new services. Virtualisation makes use of existing computing capacity or consolidates services onto new hardware platforms in a more efficient manner.
Virtualization 2.0: The Next Generation of VirtualizationEMC
In this paper, Frost & Sullivan define virtualization 2.0 and show the enhanced benefits that the latest virtualization platforms can deliver to the business.
You will learn how the virtualization 2.0 can:
- Improve your business agility, productivity, and application performance
- Provide new benefits of next generation virtualization platforms, including capacity management, predicitive analytics and data protection
The process of creating a virtual version of something be it an operating system, a storage device, a server or network resources is known as virtualization. With virtualization, enterprises and companies succeeded in integrating administrative tasks, enhancing scalability, managing workloads, and reducing operational complexities.
The benefits of employing virtualization in the corporate data center are compelling – lower operating
costs, better resource utilization, increased availability of critical infrastructure to name just a few. It is an
apparent “no brainer” which explains why so many organizations are jumping on the bandwagon. Industry
analysts estimate that between 60 and 80 percent of IT departments are actively working on server
consolidation projects using virtualization. But what are the challenges for operations and security staff
when it comes to management and ensuring the security of the new virtual enterprise? With new
technology, complexity and invariably new management challenges generally follow.
Over the last 18 months, Prism Microsystems, a leading security information and event management
(SIEM) vendor, working closely with a set of early adopter customers and prospects, has been working on
extending the capability of EventTracker to provide deep support for virtualization, enabling our customers
to get the same level of security for the virtualized enterprise as they have for their non-virtualized
enterprise. This White Paper examines the technology and management challenges that result from
virtualization, and how EventTracker addresses them.

How virtualization leads to Cloud Computing?
Cloud Computing Stack
In a general sense, virtualization, is the creation of a virtual, rather than an actual, version of something.
For example:
Google Earth, It is a virtual image of Earth which hold every detail about earth.
From a computing perspective, we might have already done some virtualization if you’ve ever partitioned a hard disk drive into more than one “virtual” drive.
Virtualization in a computing environment can be present in many different forms, some of which are:
Hardware virtualization
Storage and data virtualization
Software virtualization
Network virtualization
Virtualization refers to the creation of a virtual resource such as a server, desktop, operating system, file, storage or network.
The main goal of virtualization is to manage workloads by radically transforming traditional computing to make it more scalable.
The server administrator uses a software application to divide one physical server into multiple isolated virtual environments.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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).

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.
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.
Epistemic Interaction - tuning interfaces to provide information for AI support
Logicalis - Virtualisation overview
1. Virtualisation Overview
Virtualisation is a technology set that allows for the abstraction of ICT services from the underlying
hardware platforms. The most popular implementation of virtualisation (after network virtualisation)
is that of Server Virtualisation.
Driven primarily by the desire to maximize the efficiency of server/data centre estates, server
virtualisation allows organisations to increase the efficiency of physical server platforms. Typically,
server virtualisation achieves at least a 30% reduction in physical servers and drives server
performance efficiency up from an average of 30% usage to over 80% usage. Coupled with this is
the ability to quickly provision new services on existing physical platforms, brings speed and agility
to what was once an elongated procurement cycle before new services were brought on-line.
Simply put, virtualisation is a means by which to make more efficient use of either existing
computing capacity or consolidate services on to new hardware platforms.
This is better explained by the following example:
An x86 server running virtualisation software can host virtual machines running, for
instance, Linux or Mac OSX. The physical x86 server would be the host machine and the
virtual machines are guest machines.
Under this scenario, it would be possible to run an Exchange Server on Windows, Apache
web server on centos and a File server all on the same machine.
This approach allows the host hardware to work at nearer 90% capability.
There are a number of types and applications of virtualisation:
Hardware virtualisation or platform virtualisation. The above case is an example of this;
one item of hardware is used to emulate several - this can also be known as hardware
emulation.
Network virtualisation provides the ability to abstract logical networks from the underlying
hardware, allowing for the creation of virtual networks, which span physical devices and
boundaries.
Storage Virtualisation is the pooling of physical storage from multiple network storage
devices into what appears to be a single storage device that is managed from a central
console.

2. Application virtualisation provides a mechanism to distribute applications to desktop
machines, and for software to run in non-native environments, e.g. running a Windows app
in a Linux environment. The application is tricked into thinking it is in a native OS.
Data virtualisation presents data as an abstracted layer separate from the underlying
systems and storage structures, allowing access to multiple data sources from a single
access point.
Desktop Virtualisation - Desktop Virtualisation is the detachment of the desktop, the
operating system and the end-user applications from the underlying endpoint or device.
This enables standard thin-client end user device, tablets and other devices to access a
centrally hosted desktop environment.
Business benefits of Virtualisation
Saves money on hardware costs, as more services can be provided with less physical
hardware.
Environmentally sound. Server virtualisation consumes less power, whilst less heat is
emitted and fewer resources are needed overall.
Saves physical rack-space and the energy involved in cooling the servers.
Increases the efficiency of administration, as automation and self-service tools can be
deployed.
Deployment cost and time is reduced. There is no need to install new hardware or network
connectivity - it is simply a case of adding a new virtual server or application, which can
take minutes.
Hardware utilisation is increased from around 15-30% to 80-90%.
Back up and redundancy can be significantly more affordable. Often existing servers can
be used following a virtualisation roll out.

3. Considerations
With virtualisation comes complexity, and without a robust management framework and
automation process in place, many virtualised server estates either stall, or sprawl, replicating in
the virtual environment what occurred in the physical environment. This can often result in
increased physical estate and an inefficient virtual environment.
Managing complexity at this layer can be challenging. The focus must be on automating for
efficiency, managing to ensure the infrastructure meets the needs of the business and securing
and protecting critical resources.
Moving to virtualisation can be perceived as challenging, particularly if:
Organisations do not have the skills in-house to deploy virtualisation
Organisations do not have the tools to deploy and manage virtualisations
Network managers are wary of the complexity of virtual machines
Application owners have concerns about virtual performance.
Server virtualisation should be approach in the same way as any other IT project, with a clear
definition of the objectives, an evaluation as to what virtualisation elements the organisation will
see benefit from, and with clear roll out plans in place.
Virtualisation Glossary
“Bare Metal” installation: Where the virtualisation software is installed directly to the
hardware rather than on an operating system.
P2V (Physical to Virtual): The process of migrating from a physical environment to virtual.
Hypervisor: The software or layer that allows you to create a virtual installation on the host
hardware.
VM: Virtual Machine
Snapshot: An image of the state of a virtual machine at a specific point in time. A
snapshot includes all the data and configuration information for the VM, which allows the
machine to be rolled back to that previous state after making changes.
