Key to the definition of cloud computing is the “cloud” itself. Here , the cloud is a large group of interconnected computers. These computers can be personal computers or network servers; they can be public or private. This cloud of computers extends beyond a single company or enterprise. The applications and data served by the cloud are available to broad group of users, cross-enterprise and cross-platform. Access is via the Internet. Any authorized user can access these docs and apps from any computer over any Internet connection.
This PPT provides an introduction to cloud Computing. It briefly talks about fundamental cloud services, deployment models and the factors that made it an emerging paradigm.
Cloud computing :
Accessibility: Cloud computing facilitates the access of applications and data from any location worldwide and from any device with an internet connection.
Cost savings: Cloud computing offers businesses scalable computing resources hence saving them on the cost of acquiring and maintaining them.
Security: Cloud providers especially those offering private cloud services, have strived to implement the best security standards and procedures in order to protect client’s data saved in the cloud.
Disaster recovery: Cloud computing offers the most efficient means for small, medium, and even large enterprises to backup and restore their data and applications in a fast and reliable way.
ABSTRACT
Cloud computing promises to significantly change the way we use computers and access and store our personal and business information. With these new computing and communications paradigms arise new data security challenges. Existing data protection mechanisms such as encryption have failed in preventing data theft attacks, especially those perpetrated by an insider to the cloud provider. For securing user data from such attacks a new paradigm called fog computing can be used. Fog Computing is a paradigm that extends Cloud computing and services to the edge of the network. Similar to Cloud, Fog provides data, compute, storage, and application services to end-users. The motivation of Fog computing lies in a series of real scenarios, such as Smart Grid, smart traffic lights in vehicular networks and software defined network .This technique can monitor the user activity to identify the legitimacy and prevent from any unauthorized user access. Here we have discussed this paradigm for preventing misuse of user data and securing information.
Cloud Computing is the internet-based computing wherby shared resources, software, and information are provided to computers and other devices on demand, like the electrcity grid

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

3. INTRODUCTION
Cloud computing is Internet-based computing, whereby shared resources,
software, and information are provided to computers and other devices on
demand, like the electricity grid.
Cloud computing is a paradigm shift following the shift from mainframe
to client–server in the early 1980s. Details are abstracted from the users,
who no longer have need for expertise in, or control over, the technology
infrastructure "in the cloud" that supports them.
6. PUBLIC CLOUD
Public clouds are made available to the general public by a
service provider who hosts the cloud infrastructure.
Generally, public cloud providers like Amazon AWS,
Microsoft and Google own and operate the infrastructure and
offer access over the Internet.
With this model, customers have no visibility or control over
where the infrastructure is located.
It is important to note that all customers on public clouds
share the same infrastructure pool with limited
configuration, security protections and availability
variances.
7. PRIVATE CLOUD
Private cloud is cloud infrastructure dedicated to a
particular organization.
Private clouds allow businesses to host applications in the
cloud, while addressing concerns regarding data security
and control, which is often lacking in a public cloud
environment.
It is not shared with other organizations, whether
managed internally or by a third-party, and it can be
hosted internally or externally.
8. HYBRID CLOUD
Hybrid Clouds are a composition of two or more clouds
(private, community or public) that remain unique
entities but are bound together offering the advantages
of multiple deployment models.
In a hybrid cloud, you can leverage third party cloud
providers in either a full or partial manner, increasing
the flexibility of computing.
Augmenting a traditional private cloud with the
resources of a public cloud can be used to manage any
unexpected surges in workload.
9. ARCHITECTURE
Cloud architecture, the systems architecture of the software
systems involved in the delivery of cloud computing,
typically involves multiple cloud components communicating
with each other over application programming interfaces,
usually web services.
10. COMPONENTS
SaaS(Software as a Service): SaaS refers to software that’s made
available as a web-based service.
PaaS(Platform as a Service): Delivers development environment as a
service.
IaaS(Infrastructure as a Service): IaaS refers to computer
infrastructure (e.g., virtualization) that’s delivered as a service.
Cloud-based web services: Similar to Saas, web services in the cloud
allow you to offer services online, such as credit card processing
services, employee payroll processing or viewing an interactive map.
MSP (Managed Service Providers): The grandfather of cloud
computing, an MSP delivers applications to IT instead of end-users.
11. ADVANTAGES
FLEXIBILITY: There is a high rate of flexibility when using cloud
computing because people can opt out of using it whenever
they want too.
LOW COST: Companies can save big by employing cloud
computing as it eliminates cost for hardware and software.
SPEED & SCALES: Traditional methods to buy and configure H/W
and S/W are time consuming. There is no need to purchase and
setup H/W manually when using the cloud computing method.
CUSTOMIZE SETTING: Cloud computing also allows you to
customize your business app. This is a great benefit because the
world of online business is very competitive.
12. DISADVANTAGES
DEPENDENCY: One major disadvantages of cloud computing is
user’s dependency on the provider. Internet users don’t have
their data stored with them.
RISK: Cloud computing services means talking services from
remote servers. There is always insecurity regarding stored doc.
because users don’t have control over their S/W.
REQUIRES A CONSTANT INTERNET CONNECTION.
MIGRATION ISSUE: Migration problem is also a big concern about
cloud computing. If a user wants to switch to some other
provider then it is not easy to transfer huge data from one
provider to another.
13. CONCLUSION
So, while cloud computing is really great
and you’re probably already using it,
either for business or for personal means.
It’s a much better way to spread your
resources, and it becomes easier to
access things from longer distances.
