What is Cloud Computing...?
• Cloud Computing is the delivery of computing services, storage, databases,
networking, software, analytics and more over the internet(“the Cloud”)companies
offering these computing services are called cloud providers and typically charge for
cloud computing services based on usage.
• Cloud computing is a general term for the delivery of hosted services over the
internet.
• Cloud computing enables companies to consume a compute resource, such as a
virtual machine (VMS) storage or an application

Eg:
 Cloud computing can be used easily in one’s
personal life as well as in one’s business life. It’s
highly likely that you already use as least one, if not
many cloud computing services.

Types of Cloud Computing services
PaaS
LaaS SaaS

 Most cloud computing services fall into three broad
categories : infrastructure as a service(LaaS)platform as
a(PaaS),and software as a (SaaS).
 These are sometimes called the cloud computing stack
,because they build on top of one another.
 Knowing what they are and how they are different
makes it easier to accomplish your business goals.

Infrastructure-as-a-service (LaaS)
• The most basic category of cloud computing services. With
laaS, you rent IT infrastructure-servers and virtual
machines(VMs),storage ,networks ,operating systems-from a
cloud provider on a pay-as-you-go basis. To learn more,see
What is laaS?

Platform as a service(PaaS)
• Platform-as-a-service(PaaS)refers to cloud computing services that
supply an on-demand environment for developing, testing,
delivering, and managing software application.PaaS is designed to
make it easier for developers to quickly create web or mobile apps
,without worrying about setting up or managing the underling
infrastructure of servers, storage, network, and databases needed for
development .To learn more ,see What is PaaS?

Software as a service(SaaS)
• Software –as-a-service(SaaS) is a method for delivering software
applications over the internet , on demand and typically on a
subscription basis.with SaaS , cloud provides host and manage the
software application and underlying infrastructure , and handle any
maintenance, like software upgrades and security patching.users connect
to the application over the internet ,usually with their phone,tablet or
PC.to learn more see What is SaaS..?

Top benefits of cloud computing
 Cloud computing is a big shit form the traditional way
business think about IT resources. What is it about cloud
computing ?Why is cloud computing so popular?

01.Cost
 Cloud computing eliminates the capital expense of buying
hardware and setting up and running on-site datacenters
the racks of servers, the round the clock electricity for
power and cooling, the IT experts for managing the
infrastructure. It adds up fast.

02.Speed
 Most Cloud computing services are provided self service and on
demand, so even vast amounts of computing resources can be
provisioned in minutes , typically with just a few mouse clicks,
giving businesses a lot of flexibility and taking he pressure off
capacity planning.

03.Globalscale
 The benefits of cloud computing services include the ability to
scale elastically. In cloud speak, that means delivering the right
amount of IT resources-for example, more or less computing
power, storage, bandwidth-right when its needed, and form the
right geographic location.

04.Productivity
 On-site datacenters typically require a lot of “racking and stacking” -
hardware set up, software patching, and other time consuming IT
management chores. Cloud computing removes the need for many
of these tasks, so IT teams can spend time on achieving more
important business goals.

05.Performance
 The biggest cloud computing services run on a worldwide network of
secure datacenters, which are regular upgraded to the latest
generation of fast and efficient computing hardware. This offers several
benefits over a single corporate datacenter, including reduced network
latency for applications and greater economics of scale.

06.Reliability
 Cloud computing makes data backup, disaster recovery, and
business continuity easier and less expensive, because data can be
mirrored at multiple redundant sites on the cloud provider’s
network.

 computing boasts several attractive benefits for business and end users.
Three of the main benefits of cloud computing are:
 Self-service provisioning: end users can spin up compute resources for
almost any type of workload on demand. this eliminates the traditional
need for IT administrators to provision and manage compute resources.
 Elasticity: Companies can scale up as computing needs increase and scale
down again as demands decrease. This eliminates the need for massive
investments in local infrastructure which may or may not remain active.
 Pay per use: Compute resources are measured at a granular level, allowing
users to pay only for the resources and workloads they use.

Types of cloud deployments
 Not all clouds are the same. There are
he three different ways to deploy cloud
computing resources: public cloud,
private cloud , and hybrid cloud.

Public cloud
 Public clouds are owned and operated by a third-party cloud
service provider, which deliver their computing resources
like servers and storage over the internet. Microsoft Azure is
an example of a public cloud. With a public cloud, all
hardware, software and other supporting infrastructure is
owned and managed by the cloud provider. You access
these services and manage your account using a web
browser.

Private cloud
 A private cloud refers to cloud computing resources used exclusively
by a single business or organization. A private cloud can be physically
located on the company’s on-site datacenter. Some companies also
pay third-party service provides to host their private cloud. A private
cloud is one in which the services and infrastructure are maintained on
a private network.

 Hybrid clouds combine public and private clouds, bound together by
technology that allows data and applications to be shared between them.
By allowing data and applications to move between private and public
clouds, hybrid cloud gives business greater flexibility and more
deployment options.

How cloud computing works
 Cloud computing services all work a little differently, depending on
the provider. But many provider a friendly, browser-based dashboard
that makes it easier for IT professionals and developers to order
resources and manage their accounts. Some cloud computing
services are also designed to work with REST APIs and a command-
line interface (CLI), giving developers multiple options.

Cloud computing security
 Security remains a primary concern for business contemplating cloud
adoption—especially public cloud adoption. Public cloud providers share
their underlying hardware infrastructure between numerous customers,
as public cloud is a multi-tenant environment. This environment
demands copious isolation between logical compute resources. At the
same time, access to public cloud storage and compute resources is
guarded by account logon credentials.

Social Networking
 Perhaps the most famous use of cloud computing , which does not strike people as
“cloud computing” at first glance is social networking websites, including facebook,
linkedin, MySpace ,Twitter, and many,many others. The main idea of social
networking is to find people you already know or people you would like to know and
share your information with them. Of course, when you share your information with
these people, you are also sharing it with the people who run the service.
 While the primary purpose of social networking previously was connecting people,
businesses can use social networking too. By creating a facebook fan page , a
business can connect with its customers, and at the same time, those customers will
be promoting your business. Also , viral marketing tactics can be used in combination
with social networks. There are public relations experts who specialize in social media
marketing.

E-Mail
 Some of the biggest cloud computing services are web-based e-
mail. As of January 2009, over 500 million people used Microsoft’s
Web-based e-mail , Hotmail or Windows Live Mail, using a cloud
computing e-mail solution allows the mechanics of hosting an e-mail
server and maintaining it to be taken out of your hands. It also
means that your e-mail is accessible from anywhere.

Document/Spreadsheet/Other Hosting Services
 As made famous by Google Docs, a number of services like Zoho Office exist on the Internet
that allow you to keep and edit your documents online. By doing so, the documents will be
accessible anywhere, and you can share the documents and collaborate on them. Multiple
people can work in the same documents simultaneously.
 A new online project management tool, Onit, is for “anyone and everyone who manage
projects-big, small, business, legal.” For Robert Ambrogi’s preview. Legal Project
Management in the cloud, or access the link below to go directly to Onit’s homepage.
 Yahoo!’s Flickr and Google’s Picasa offer hosting for photographs that you want to share
with friends, family, or the world. People can comments on the photographs, much like they
can on Facebook, but these specialized photo hosting services offer some perks for the
photography enthusiast.

Backup Services
 Even if you do use services to keep all our documents and photos, chances are you still
have data on your personal computer.one of the biggest problems with personal
computing has been the tendency to lose that data if your computer is stolen,
destroyed, or the storage device damaged. This is where backup comes in. sometimes
,even backing up to media you have isn’t good enough –you need to store the data off-
site for more complete protection.services like JungleDisk, Carbonite and Mozy allow
you to automatically back up all your data to servers spread around the country or world
for a surprisingly low price. Of course , your data is then susceptible to security
breaches.
 Similarly, services like Syncplicity and Dropbox (both offer free versions) make it easy to
keep local copies of files on multiple computers synchronized while keeping a copy in
the “cloud”. Some of these services will even keep previous versions of files or deleted
files in case you happen to delete or mess up an important file.

Banking and Financial Services
 Consumers store personal financial information to cloud
computing service provides. In addition, consumers store tax
records using free or low cost online backup services.
