Grid computing vs Cloud computing
Cloud Computing offers an on-demand and scalable access to a shared pool of resources hosted in a data center at providers’ site. It reduces the overheads of up-front investments and financial risks for the end-user. Regardless of the fact that cloud computing offers great advantages to the end users, there are several challenging issues that are mandatory to be addressed.
Cloud computing is used to define a new class of computing that is based on the network technology. Cloud computing takes place over the internet. It comprises of a collection of integrated and networked hardware, software and internet infrastructures. These infrastructures are used to provide various services to the users. Distributed computing comprises of multiple software components that belong to multiple computers. The system works or runs as a single system. Cloud computing can be referred to as a form that originated from distributed computing and virtualization.
This presentation will highlight the key legal issues associated with cloud computing and some implementation methods for minimizing or mitigating those risks.
There are numerous legal issues in cloud computing like operational, legislative or regulatory, security, third party contractual limitations, risk allocation or mitigation, and jurisdictional issues. Security, privacy and confidentiality remain the biggest concern for the data owner, as when the data is stored on the cloud the same might be accessible to multiple users. There is concern for its safety and protection of valuable data and trade secrets. Then there are intellectual property issues regarding ownership of and rights in information and services placed in the cloud.
Cloud computing is a type of computer technology that allows people to access shared computer resources, such as computing, storage, and applications, through internet-connected devices. These resources can then be used on demand for both business and personal purposes.

Conclusion
Cloud computing is an internet-based computing technology, where shared re-sources
such as software, platform, storage and information are provided to customers on demand.
Cloud computing is a computing platform for sharing resources that include infrastructures,
software, applications, and business processes. The exact definition of cloud computing is A
large-scale distributed computing paradigm that is driven by economies of scale, in which a
pool of abstracted, virtualized, dynamically scalable, managed computing power, storage,
platforms, and services are delivered on demand to external customers over the Internet .
Abstract--The paper identifies the issues and the solution to overcome these problems. Cloud computing is a subscription based service where we can obtain networked storage space and computer resources. This technology has the capacity to admittance a common collection of resources on request. It is the application provided in the form of service over the internet and system hardware in the data centers that gives these services. But having many advantages for IT organizations cloud has some issues that must be consider during its deployment. The main concern is security privacy and trust. There are various issues that need to be dealt with respect to security and privacy in a cloud computing scenario [4].
Keywords--Cloud, Issues, Security, Privacy, Resources, Technology.
A study of reserach paper they investigate the problem of seamless VM migrations in the DCN. Leveraging the benefit of decoupling a service from its physical location in the emerging technique named data networking; we propose a named service framework to support seamless VM migrations. In comparison with other approaches, their approach has following advantages: 1) the VM migration is interruption free; 2) the overhead to maintain the routing information is less than that caused by classic NDN; 3) the routing protocol is robust to both link and node failures; 4) the framework inherently supports the implementation of a distributed load balancing algorithm, via which requests are distributed to VMs in balance. The analysis and simulation results verify these benefits.
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.

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.
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.

3. What is Cloud ????
Term cloud is used as a metaphor for internet.
Cloud computing relies on sharing hardware and
software resources over a network rather than on local
servers or personal devices. This network of servers
and connections is collectively known as the cloud.
The cloud is a next Generation platform that
provides dynamic resource pools, virtualization, and
high availability.

5. Cloud computing
Cloud computing is how data is accessed using
remote servers via Internet.
Cloud computing is internet based computing, where
by shared resources, software and information are proved
to computer and other devices on demand, like the
electricity grid.
It has a business application.
Cloud computing describes both a platform and a type
of application. A cloud computing platform dynamically
provisions, configures, reconfigures, and deprovisions
servers as needed.
6. Why Cloud Computing?
Hide complexity of IT infrastructure management
Massive configurability
Reliability
High Performance
Specifiable configurability
Low cost compared to dedicated infrastructure.
9. Cloud computing Architecture
The two most components of cloud
computing architecture are
1)the front end
2) the back end
The front end is the part seen by the
client, i.e. the computer user.
The back end of the cloud computing
architecture is the ‘cloud’ itself,
comprising various computers, servers
and data storage devices.
11. Cloud Storage
• User send the copies of data
files he wants to store to the
server.
• The user can retrieve this
stored data from the server
as and when required.
• There is only one data
server needed to be
connected to the internet.
12. Cloud Storage
Architecture
A typical cloud
storage system
architecture
includes a master
control server and
several storage
servers, as shown
in the fig.
14. 1. Public Cloud Storage :
∗ Data offered by third party vender.
1. Private Cloud Storage:
∗ Cloud is dedicated to single organization.
1. Hybrid Cloud Storage:
∗ Combination of public and private storage.
1. Community Cloud Storage:
∗ Shared by several organizations having same policies.
Data Deployment models on
Cloud
15. • Cloud computing can provide infinite computing resources on
demand due to its high scalability in nature, which eliminates the
needs for Cloud service providers to plan far ahead on hardware
provisioning.
• The cloud gives access to the data but the challenge is to ensure
that only authorized entities have to access the data.
Security in Cloud Computing
16. ∗ Data-in-Transit
‐ Confidentiality and integrity using secured protocol
‐ Communication between the two hosts is identified,
authenticated, authorized, and private.
∗ Data-at-Rest
‐ data is protected by strong encryption and the key is not
present on the media itself .
∗ Data Lineage
‐ Knowing when and where the data was located within cloud
is important for audit purposes.
Aspects of Data Security
17. * Data Provenance:
‐ Computational accuracy and data integrity
‐ to control access to information and computing resource
* Data Remanence:
‐ Inadvertent disclosure of sensitive information is possible.
* Multi-cloud
‐ Spread the risk
‐Increase redundancy per application
‐Increase chance of mission completion for critical applications
18. ∗ Virtual Cloud Hosting :
‐ offering secured and reliable low cost solutions to cloud
computing clients, round the globe.
‐ maintain the security for every website they cater to
* Cloud Firewall :
‐ It can collect detailed information threats on the Internet
constantly, including the continuous attacks, botnet
harvest , malware outbreaks .
19. 1.Network Level:
‐ Ensuring confidentiality and integrity of your organization’s data‐in‐
transit to and from your public cloud provider
2.Application Level:
‐ End user security
‐ Responsibility for Web application security in the cloud
‐ implements testing and acceptance procedures for outsourced
application code
Infrastructure Security
20. ∗ Identity Management Module
∗ In this approach, an identity has identifiers or attributes that
identify and define the user. The notable idea of user‐centric
approach allows users to control their own digital identities
and also takes away the complexity of IDM from the
enterprises, therefore allowing them to focus on their own
functions.
Authentication
21. Conclusion
Storage of data on the cloud redefines the way
that we construct, access, and manage storage within
an enterprise. Some kind of data is more preferable
to be stored on the cloud than others.
Data stored on clouds is more SECURE than
those stored on transient servers.
