The main advantages are lower costs, improved performance, unlimited storage and easier collaboration. However, it requires a constant internet connection and stored data may not be fully secure.
Cloud computing refers to storing and accessing data and programs over the Internet instead of a local computer's hard drive. It offers on-demand access to a shared pool of configurable computing resources like networks, servers, storage, applications and services. Users can scale resources up or down depending on their needs. Cloud services provide easy access from anywhere via a web browser while automatically handling maintenance and updates behind the scenes. While cloud computing offers opportunities to reduce costs and improve access through economies of scale, it also raises security, control and reliability concerns that need to be addressed.

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise boosts blood flow, releases endorphins, and promotes changes in the brain which help regulate emotions and stress levels.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
The document discusses the benefits of meditation for reducing stress and anxiety. Regular meditation practice can help calm the mind and body by lowering heart rate and blood pressure. Studies have shown that meditating for just 10-20 minutes per day can have significant positive impacts on both mental and physical health.
Virtualization allows multiple operating systems and applications to run concurrently on a single physical machine. It abstracts the physical infrastructure into virtual resources that can be allocated to virtual machines. Recent trends in virtualization include processor, memory, storage, network, data, and application virtualization. Processor virtualization allows VMs to share virtual processors. Memory virtualization provides virtual main memory to VMs. Storage virtualization maintains backups of VM data. Network virtualization abstracts physical network components into a virtual network. Application virtualization isolates individual copies of applications for users. While virtualization offers benefits like reduced costs and improved utilization, it can also demand powerful infrastructure and lead to performance issues or single points of failure.
Cloud computing is a model that provides on-demand access to a shared pool of configurable computing resources. It has characteristics of on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. There are three main service models - Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). The document then discusses Infrastructure as a Service (IaaS) specifically, describing Amazon EC2 as an example of IaaS and its key concepts such as AMIs, regions, storage options, networking, security, monitoring and auto-scaling.

Networking is a telecommunications network that allows computers to exchange data. In
computer networks, networked computing devices pass data to each other along data
connections. Data is transferred in the form of packets. The connections between nodes are
established using either cable media or wireless media.
Online train ticket booking system project.pdfKamal Acharya
Rail transport is one of the important modes of transport in India. Now a days we
see that there are railways that are present for the long as well as short distance
travelling which makes the life of the people easier. When compared to other
means of transport, a railway is the cheapest means of transport. The maintenance
of the railway database also plays a major role in the smooth running of this
system. The Online Train Ticket Management System will help in reserving the
tickets of the railways to travel from a particular source to the destination.
Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

2. What is Cloud Computing?
• Cloud Computing is a general term used to describe a new
class of network based computing that takes place over the
Internet,
– basically a step on from Utility Computing
– a collection/group of integrated and networked hardware,
software and Internet infrastructure (called a platform).
– Using the Internet for communication and transport
provides hardware, software and networking services to
clients
• These platforms hide the complexity and details of the
underlying infrastructure from users and applications by
providing very simple graphical interface or API (Applications
Programming Interface).
2
3. What is Cloud Computing?
• In addition, the platform provides on demand
services, that are always on, anywhere,
anytime and any place.
• Pay for use and as needed, elastic
– scale up and down in capacity and functionalities
• The hardware and software services are
available to
– general public, enterprises, corporations and
businesses markets
3
4. Cloud Summary
• Cloud computing is an umbrella term used to refer to
Internet based development and services
• A number of characteristics define cloud data,
applications services and infrastructure:
– Remotely hosted: Services or data are hosted on remote
infrastructure.
– Ubiquitous: Services or data are available from anywhere.
– Commodified: The result is a utility computing model
similar to traditional that of traditional utilities, like gas
and electricity - you pay for what you would want!

11
12. Basic Cloud Characteristics
• The “no-need-to-know” in terms of the underlying
details of infrastructure, applications interface with
the infrastructure via the APIs.
• The “flexibility and elasticity” allows these systems
to scale up and down at will
– utilising the resources of all kinds
• CPU, storage, server capacity, load balancing, and databases
• The “pay as much as used and needed” type of
utility computing and the “always on!, anywhere
and any place” type of network-based computing.
12
13. Basic Cloud Characteristics
• Cloud are transparent to users and
applications, they can be built in multiple
ways
– branded products, proprietary open source,
hardware or software, or just off-the-shelf PCs.
• In general, they are built on clusters of PC
servers and off-the-shelf components plus
Open Source software combined with in-
house applications and/or system software.
13
14. Software as a Service (SaaS)
• SaaS is a model of software deployment where an
application is hosted as a service provided to
customers across the Internet.
• Saas alleviates the burden of software
maintenance/support
– but users relinquish control over software versions and
requirements.
• Terms that are used in this sphere include
– Platform as a Service (PaaS) and
– Infrastructure as a Service (IaaS)
14
15. Virtualization
• Virtual workspaces:
– An abstraction of an execution environment that can be made
dynamically available to authorized clients by using well-defined
protocols,
– Resource quota (e.g. CPU, memory share),
– Software configuration (e.g. O/S, provided services).
• Implement on Virtual Machines (VMs):
– Abstraction of a physical host machine,
– Hypervisor intercepts and emulates instructions from VMs, and allows
management of VMs,
– VMWare, Xen, etc.
• Provide infrastructure API:
– Plug-ins to hardware/support structures Hardware
OS
App App App

Virtualized Stack
16. Virtual Machines
• VM technology allows multiple virtual
machines to run on a single physical machine.

etc.
Performance: Para-virtualization (e.g. Xen) is very close to raw physical
performance!
16
17. What is the purpose and benefits?
• Cloud computing enables companies and
applications, which are system infrastructure
dependent, to be infrastructure-less.
• By using the Cloud infrastructure on “pay as used
and on demand”, all of us can save in capital and
operational investment!
• Clients can:
– Put their data on the platform instead of on their own
desktop PCs and/or on their own servers.
– They can put their applications on the cloud and use the
servers within the cloud to do processing and data
manipulations etc. 18
18. Cloud-Sourcing
• Why is it becoming a Big Deal:
– Using high-scale/low-cost providers,
– Any time/place access via web browser,
– Rapid scalability; incremental cost and load sharing,
– Can forget need to focus on local IT.
• Concerns:
– Performance, reliability, and SLAs,
– Control of data, and service parameters,
– Application features and choices,
– Interaction between Cloud providers,
– No standard API – mix of SOAP and REST!
– Privacy, security, compliance, trust…
19
21. Cloud Storage
• Several large Web companies are now exploiting the
fact that they have data storage capacity that can be
hired out to others.
– allows data stored remotely to be temporarily cached on
desktop computers, mobile phones or other Internet-
linked devices.
• Amazon’s Elastic Compute Cloud (EC2) and Simple
Storage Solution (S3) are well known examples
– Mechanical Turk
22
22. Amazon Simple Storage Service (S3)
• Unlimited Storage.
• Pay for what you use:
– $0.20 per GByte of data transferred,
– $0.15 per GByte-Month for storage used,
– Second Life Update:
• 1TBytes, 40,000 downloads in 24 hours - $200,
23
23. Utility Computing – EC2
• Amazon Elastic Compute Cloud (EC2):
– Elastic, marshal 1 to 100+ PCs via WS,
– Machine Specs…,
– Fairly cheap!
• Powered by Xen – a Virtual Machine:
– Different from Vmware and VPC as uses “para-virtualization” where
the guest OS is modified to use special hyper-calls:
– Hardware contributions by Intel (VT-x/Vanderpool) and AMD (AMD-
V).
– Supports “Live Migration” of a virtual machine between hosts.
• Linux, Windows, OpenSolaris
• Management Console/AP
24
24. EC2 – The Basics
• Load your image onto S3 and register it.
• Boot your image from the Web Service.
• Open up required ports for your image.
• Connect to your image through SSH.
• Execute you application…
25
25. Opportunities and Challenges
• The use of the cloud provides a number of
opportunities:
– It enables services to be used without any understanding
of their infrastructure.
– Cloud computing works using economies of scale:
• It potentially lowers the outlay expense for start up companies, as
they would no longer need to buy their own software or servers.
• Cost would be by on-demand pricing.
• Vendors and Service providers claim costs by establishing an
ongoing revenue stream.
– Data and services are stored remotely but accessible from
“anywhere”.
26
26. Opportunities and Challenges
• In parallel there has been backlash against cloud computing:
– Use of cloud computing means dependence on others and that could
possibly limit flexibility and innovation:
• The others are likely become the bigger Internet companies like Google
and IBM, who may monopolise the market.
• Some argue that this use of supercomputers is a return to the time of
mainframe computing that the PC was a reaction against.
– Security could prove to be a big issue:
• It is still unclear how safe out-sourced data is and when using these
services ownership of data is not always clear.
– There are also issues relating to policy and access:
• If your data is stored abroad whose policy do you adhere to?
• What happens if the remote server goes down?
• How will you then access files?
• There have been cases of users being locked out of accounts and losing
access to data.
27
27. Advantages of Cloud Computing
• Lower computer costs:
– You do not need a high-powered and high-priced computer
to run cloud computing's web-based applications.
– Since applications run in the cloud, not on the desktop PC,
your desktop PC does not need the processing power or hard
disk space demanded by traditional desktop software.
– When you are using web-based applications, your PC can be
less expensive, with a smaller hard disk, less memory, more
efficient processor...
– In fact, your PC in this scenario does not even need a CD or
DVD drive, as no software programs have to be loaded and
no document files need to be saved.
28
28. Advantages of Cloud Computing
• Improved performance:
– With few large programs hogging your computer's
memory, you will see better performance from your PC.
– Computers in a cloud computing system boot and run
faster because they have fewer programs and processes
loaded into memory…
• Reduced software costs:
– Instead of purchasing expensive software applications, you
can get most of what you need for free-ish!
• most cloud computing applications today, such as the Google Docs suite.
– better than paying for similar commercial software
• which alone may be justification for switching to cloud applications.
29
29. Advantages of Cloud Computing
• Instant software updates:
– Another advantage to cloud computing is that you are no longer faced
with choosing between obsolete software and high upgrade costs.
– When the application is web-based, updates happen automatically
• available the next time you log into the cloud.
– When you access a web-based application, you get the latest version
• without needing to pay for or download an upgrade.
• Improved document format compatibility.
– You do not have to worry about the documents you create on your
machine being compatible with other users' applications or OSes
– There are potentially no format incompatibilities when everyone is
sharing documents and applications in the cloud.
30
30. Advantages of Cloud Computing
• Unlimited storage capacity:
– Cloud computing offers virtually limitless storage.
– Your computer's current 1 Tbyte hard drive is small
compared to the hundreds of Pbytes available in the
cloud.
• Increased data reliability:
– Unlike desktop computing, in which if a hard disk crashes
and destroy all your valuable data, a computer crashing in
the cloud should not affect the storage of your data.
• if your personal computer crashes, all your data is still out there in
the cloud, still accessible
– In a world where few individual desktop PC users back up
their data on a regular basis, cloud computing is a data-
safe computing platform!
31
31. Advantages of Cloud Computing
• Universal document access:
– That is not a problem with cloud computing, because you
do not take your documents with you.
– Instead, they stay in the cloud, and you can access them
whenever you have a computer and an Internet connection
– Documents are instantly available from wherever you are
• Latest version availability:
– When you edit a document at home, that edited version is
what you see when you access the document at work.
– The cloud always hosts the latest version of your
documents
• as long as you are connected, you are not in danger of having an outdated
version 32
32. Advantages of Cloud Computing
• Easier group collaboration:
– Sharing documents leads directly to better collaboration.
– Many users do this as it is an important advantages of cloud
computing
• multiple users can collaborate easily on documents and projects
• Device independence.
– You are no longer tethered to a single computer or network.
– Changes to computers, applications and documents follow
you through the cloud.
– Move to a portable device, and your applications and
documents are still available.
33
33. Disadvantages of Cloud Computing
• Requires a constant Internet connection:
– Cloud computing is impossible if you cannot connect to
the Internet.
– Since you use the Internet to connect to both your
applications and documents, if you do not have an
Internet connection you cannot access anything, even
your own documents.
– A dead Internet connection means no work and in areas
where Internet connections are few or inherently
unreliable, this could be a deal-breaker.
34
34. Disadvantages of Cloud Computing
• Does not work well with low-speed connections:
– Similarly, a low-speed Internet connection, such as that
found with dial-up services, makes cloud computing
painful at best and often impossible.
– Web-based applications require a lot of bandwidth to
download, as do large documents.
• Features might be limited:
– This situation is bound to change, but today many web-
based applications simply are not as full-featured as their
desktop-based applications.
• For example, you can do a lot more with Microsoft PowerPoint
than with Google Presentation's web-based offering
35
35. Disadvantages of Cloud Computing
• Can be slow:
– Even with a fast connection, web-based applications can
sometimes be slower than accessing a similar software
program on your desktop PC.
– Everything about the program, from the interface to the
current document, has to be sent back and forth from
your computer to the computers in the cloud.
– If the cloud servers happen to be backed up at that
moment, or if the Internet is having a slow day, you would
not get the instantaneous access you might expect from
desktop applications.
36
36. Disadvantages of Cloud Computing
• Stored data might not be secure:
– With cloud computing, all your data is stored on the cloud.
• The questions is How secure is the cloud?
– Can unauthorised users gain access to your confidential data?
• Stored data can be lost:
– Theoretically, data stored in the cloud is safe, replicated
across multiple machines.
– But on the off chance that your data goes missing, you have
no physical or local backup.
• Put simply, relying on the cloud puts you at risk if the cloud lets you
down.
37
37. Disadvantages of Cloud Computing
• HPC Systems:
– Not clear that you can run compute-intensive HPC
applications that use MPI/OpenMP!
– Scheduling is important with this type of application
• as you want all the VM to be co-located to minimize communication
latency!
• General Concerns:
– Each cloud systems uses different protocols and different
APIs
• may not be possible to run applications between cloud based systems
– Amazon has created its own DB system (not SQL 92), and
workflow system (many popular workflow systems out there)
• so your normal applications will have to be adapted to execute on
these platforms.
38
38. The Future
• Many of the activities loosely grouped together under cloud
computing have already been happening and centralised
computing activity is not a new phenomena
• Grid Computing was the last research-led centralised
approach
• However there are concerns that the mainstream adoption of
cloud computing could cause many problems for users
• Many new open source systems appearing that you can install
and run on your local cluster
– should be able to run a variety of applications on these systems
39
Editor's Notes
Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
cloud computing customers do not own the physical infrastructure.
Cloud computing users avoid capital expenditure (CapEx) on hardware, software, and services when they pay a provider only for what they use.
Low shared infrastructure and costs, low management overhead, and immediate access to a broad range of applications
ScalabilityInfrastructure capacity allows for traffic spikes and minimizes delays.
ResiliencyCloud providers have mirrored solutions to minimize downtime in the event of a disaster. This type of resiliency can give businesses the sustainability they need during unanticipated events.
Homogeneity: No matter which cloud provider and architecture an organization uses, an open cloud will make it easy for them to work with other groups, even if those other groups choose different providers and architectures.
On-demand self-service. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service’s provider.
Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling. Multi-tenant model.. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, network bandwidth, and virtual machines.
Rapid elasticity. Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured Service. Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts).
IaaSdelivers computer infrastructure, typically a platform virtualization environment, as a service. Rather than purchasing servers, software, data center space or network equipment, clients instead buy those resources as a fully outsourced service.
PaaSdeliver a computing platform where the developers can develop their own applications.
SaaSis a model of software deployment where the software applications are provided to the customers as a service.
