The origin of the term cloud computing is unclear but it refers to computing resources that are dynamically provisioned over the internet. Early concepts of cloud computing involved time-sharing mainframe computers in the 1950s and virtual machines in the 1970s. Telecommunications companies started offering virtual private networks in the 1990s. Grid computing, utility computing, SaaS, and cloud computing evolved the concept further, providing on-demand access to computing resources and applications delivered as a service.
Cloud computing refers to flexible, on-demand access to shared computing resources via the internet. Resources such as memory, storage, and processing power can be allocated as needed without direct involvement of IT staff. This allows organizations to scale their infrastructure up or down easily based on current needs. The term "cloud" originated as a symbol used to represent the public internet in network diagrams. Moving applications and services to cloud providers over the internet is now commonly referred to as migrating to the "cloud".

The enterprise landscape is rapidly changing. Data is ubiquitous. Information is flowing into an organization’s applications from more sources than ever before. Business expec-tations are also changing. Corporations today demand speed and flexibility from their applications. Enterprise want services that allow them to make better business decisions, create more satisfied customers, and react ever more quickly to evolving market condi-tions. Current economic circumstances and increased competition are also driving the demand for a more effective model to deliver applications and services.
This relentless push for a faster, better and more cost-effective technology delivery model has set the stage for new approaches to application development, deployment and management. Several technologies such as grid computing, virtualization, and service-oriented architecture (SOA) have offered partial solutions for enterprises that require applications with greater scalability, agility and easier management capabilities. However, these alone have not been enough.
Enter cloud computing, an innovative model for delivering IT infrastructure, applications and data that shifts the emphasis from static, stand-alone application silos to dynamic, shared environments, dynamically allocated among various tasks and accessed via a network.
Today, many forward-thinking enterprises are using cloud environments to take advan-tage of the increased scalability, agility, automation, and efficiency that this technology can deliver.

Cloud computing basically involves delivering hosted services over the Internet to store, manage, and process data, instead of using local server or a personal computer. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). In scientific terms, cloud computing is a synonym for distributed computing over a network which means the ability to run a program on many connected computers at the same time. Therefore it involves a large number of computers that are connected through a real-time communication network.
Cloud computing delivers computing services as utilities over the internet, similar to how electricity or water are provided. There are different types of cloud deployment models including public, private, hybrid, and community clouds. Additionally, there are three main service models - Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides virtual computing resources, PaaS provides development platforms, and SaaS provides complete software solutions delivered over the internet. Cloud computing offers benefits like on-demand provisioning, elastic scaling, pay-per-use billing, workload resilience, and migration flexibility.

CLOUD COMPUTING AND SERVICES BY SAIKIRAN PANJALASaikiran Panjala
Cloud computing refers to accessing computer applications via the internet rather than a local server or personal device. It allows users to access applications from anywhere using any device. There are different types of cloud computing models including infrastructure as a service, platform as a service, and software as a service. Cloud computing provides advantages like scalability, availability, and only paying for resources used, but also risks around security, privacy, and vendor lock-in.
This Presentation will give you the introduction to Cloud Computing. This PPT was presented by me as an assignment in my final year of B.Tech degree. I hope it would prove beneficial to your understanding of this subject. Thank You!
Cloud computing uses remote servers accessed via the internet to store and manage data rather than local drives. It allows organizations to store information in the cloud and access it from anywhere using an internet connection. Cloud computing architecture has a front end accessed by clients and a back end managed by service providers, with components including client infrastructure, applications, services, runtime environments, storage, security, and the internet connecting them. Common cloud service models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
Cloud computing provides on-demand access to shared computing resources like applications and storage over the Internet. It allows users to create, configure, and customize applications online. Cloud services include email, web conferencing, and customer relationship management applications. Cloud computing offers benefits like flexibility, disaster recovery, collaboration, and mobility by allowing access to resources from anywhere. However, it also presents risks like downtime, security issues, and vendor lock-in.
Cloud computing provides on-demand access to IT resources and applications from the Internet. There are three service models - Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides fundamental computing resources, PaaS supplies platforms for developing and deploying applications, and SaaS delivers software applications to users. Cloud computing offers advantages like reduced costs, improved performance and collaboration, but also disadvantages such as reliance on internet and potential security and speed issues.
The term Cloud refers to a Network or Internet. In other words, we can say that Cloud is something, which is present at remote location. Cloud can provide services over network, i.e., on public networks or on private networks, i.e., WAN, LAN or VPN.
Applications such as e-mail, web conferencing, customer relationship management (CRM), all run in cloud.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Introduction of cloud By Pawan Thakur
1. Introduction of Cloud Computing
By : Prof. Pawan Thakur
HOD Computer Department ,
Vidyasagar Institute of Management (VIM), Bhopal
At the end of this presentation we will be able to understand:
Overview
Definition of Cloud Computing
Characteristics of Cloud Computing
Service Delivery Models (IAAS, PAAS and SAAS)
Cloud Deployment Models/ Types of Cloud
Pros and Cons of Cloud Computing
2. The term Cloud refers to a Network or
Internet.
In other words we can say that Cloud is
something which is present at remote
location.
Cloud can provide services over network,
i.e., on public networks or on private
networks, i.e. WAN, LAN or VPN.
The applications such as e-mail, web
conferencing, CRM all run in cloud.
Instead of keeping data on your own hard drive we use a service over
the Internet at another location to store your information or use its
applications.
When we store our photos online instead of on our home computer, use
webmail, a social networking site you are using a “Cloud computing”
service
Overview of Cloud
3. Many companies are delivering services from the cloud. Some
notable examples as of July, 2014 include the following:
4. DEFINITIONS OF CLOUD COMPUTING
The Cloud computing is delivery of computing services over Internet.
It allows individuals and businesses to use software and hardware that are
managed by third parties at remote locations.
Cloud Computing refers to manipulating,
configuring, and accessing the applications
online. It offers online data storage,
infrastructure and application.”
We need not to install a piece of software on our
local PC and this is how the cloud computing
overcomes platform dependency
Cloud computing means on demand delivery of IT
resources via the internet with pay-as-you-go
pricing. It provides a solution of IT infrastructure
in low cost.”
5. NIST Characteristics of Cloud Computing
1. On-demand self-service. A consumer can
use computing capabilities such as server time
and network storage automatically without
requiring human interaction with each service
provider.
2. Broad network access. The capabilities are
available over the network .
They can accessed through standard
mechanisms by heterogeneous thin client
platforms e.g., mobile phones, tablets, laptops,
and workstations.
3. Resource pooling. The provider's computing resources are pooled to serve multiple
consumers using a multi-tenant model.
The different physical and virtual resources dynamically assigned and reassigned
according to consumer demand.
4. Rapid elasticity. The capabilities can be elastically provisioned and released.
5. Measured service. Cloud systems automatically control and optimize resource.
It leverage the metering capability at some level of abstraction appropriate to the type
of service e.g., storage, processing, bandwidth and active user accounts.
6. Service Delivery Models
(SaaS, Paa S and IaaS,)
“The cloud service models are Software as a
Service (SaaS), Platform as a Service' (PaaS) and
Infrastructure as a Service (IaaS).”
1. Software as a Service (SaaS). The
capability provided to the consumer is
to use the provider’s applications
running on a cloud infrastructure.
There are several SaaS applications some of
them are listed below:
Billing and Invoicing System
Customer Relationship Management (CRM)
applications
Help Desk Applications
Human Resource (HR) Solutions
7. 2. Platform as a Service (PaaS). PaaS offers
the runtime environment for applications. It also
offers development & deployment tools, required to
develop applications. Examples of PaaS offerings
include:
Google App Engine. The platform is used to develop and
run Java, Python and Go applications on Google’s
infrastructure.
Microsoft Windows Azure. It is on-demand compute and
storage services as well as a development and deployment
platform for applications that run on Windows.
Salesforce Force.com. This platform is used to build and run
applications and components bought from App Exchange or
custom applications.
3. Infrastructure as a Service (IaaS). The capability
provided to the consumer is to provision processing,
storage, networks, and other fundamental computing
resources where the consumer is able to deploy and run
arbitrary software, which can include operating systems and
applications. IaaS also offers:
Virtual machine disk storage, Virtual local area network (VLANs)
Load balancers. IP addresses, Software bundles
8. CLOUD DEPLOYMENT MODELS /TYPES OF CLOUD
Public cloud. The public cloud allows
systems and services to be easily accessible
to general public e.g., Google, Amazon,
Microsoft offers cloud services via
Internet.
Private cloud. The private cloud allows
systems and services to be accessible within
an organization.
The Private Cloud is operated only within a single organization. However It may be
managed internally or by third-party.
Hybrid Cloud. The hybrid cloud is a
mixture of public and private cloud .
Non-critical activities are performed
using public cloud while the critical
activities are performed using private
cloud.
Community Cloud. The community cloud allows system and services to be accessible
by group of organizations. It shares the infrastructure between several organizations from a
specific community. It may be managed internally or by the third-party .
9. Pros:
Lower-cost computers for users
Improved performance
Lower it infrastructure costs
Fewer maintenance issues
Lower software costs
Instant software updates
Increased computing power
Unlimited storage capacity
Increased data safety
Improved compatibility between operating
systems

Cons:
•Requires a constant internet
connection
•Does not work well with low-speed
connections
•Can be slow
•Features might be limited
•Stored data might not be secure
• If the cloud loses your data you are
screwed
