This document discusses cloud computing, including what it is, the services it provides, and its advantages and disadvantages. Cloud computing relies on sharing computing resources over the internet rather than local hardware. The main types of cloud services are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Cloud computing offers benefits like lower costs, improved performance and access, but also risks like security and reliability depending on internet connectivity.

3. Introduction
• With traditional desktop computing, we run copies of software
programs on our own computer. The documents we create are stored
on our own pc.
• With cloud computing, the software programs one use aren’t run
from one’s personal computer, but are rather stored on servers
accessed via the Internet.
4. What Is Cloud Computing
• Cloud computing is a type of computing that relies on sharing
computing resources rather than having local servers or
personal devices to handle applications.
• In simple Cloud computing is using the internet to access someone
else's software running on someone else's hardware in someone else's
data center.
5. Cloud Computing Services
There are mainly 3 computing services given as:
1. Software as a Service (SaaS)
2. Platform as a Service (PaaS)
3. Infrastructure as a Service (IaaS)
6. Defined as service-on-demand, where a provider will license software
tailored.
In the SaaS model, cloud providers install and operate application
software in the cloud and cloud users access the software from cloud
clients.
Examples of SaaS include: Google Apps, Microsoft Office 365, Onlive,
GT Nexus, Marketo, and TradeCard.
SaaS
7. PaaS
In the PaaS model, cloud providers deliver a computing platform
typically including operating system, programming language
execution environment, database, and web server.
Examples of PaaS include: AWS Elastic Beanstalk, Cloud Foundry,
Heroku, Force.com, EngineYard, Mendix, OpenShift, Google App
Engine, Windows Azure Cloud Services and OrangeScape
8. IaaS
In the most basic cloud-service model, providers of IaaS offer
computers physical or (more often) virtual machines and other
resources. IaaS clouds often offer additional resources such as a virtual-
machine disk image library, raw (block) and file-based storage,
firewalls, load balancers, IP addresses, virtual local area networks
(VLANs), and software bundles.
Examples of IaaS providers include: Amazon EC2, Google Compute
Engine, HP Cloud, iland, Joyent, LeaseWeb, Linode, NaviSite, Oracle
Infrastructure as a Service
9. Cloud Storage
• Cloud storage means "the storage of data online in the cloud," wherein
a company's data is stored in and accessible from multiple distributed
and connected resources that comprise a cloud.
• Cloud storage can provide the benefits of greater accessibility and
reliability; rapid deployment; strong protection for data
backup, archival and disaster recovery purposes.
10. Types of Cloud Storage
1. Public Cloud
2. Private Cloud
3. Hybrid Cloud
11. Types of Cloud Storage
Public Cloud
• Computing infrastructure is hosted by cloud vendor at the vendors premises.
• and can be shared by various organizations.
• E.g. : Amazon, Google, Microsoft, Sales force
Private Cloud
• The computing infrastructure is dedicated to a particular organization and not
shared with other organizations.
• more expensive and more secure when compare to public cloud.
• E.g. : HP data center, IBM, Sun, Oracle, 3tera
Hybrid Cloud
• Organizations may host critical applications on private clouds.
• where as relatively less security concerns on public cloud.
• usage of both public and private together is called hybrid cloud.
12. Advantages
1. Lower computer costs.
2. Improved performance.
3. Reduced software costs.
4. Improved document format compatibility.
5. Unlimited storage capacity.
6. Increased data reliability.
7. Universal document access.
8. Latest version availability
9. It reduces global warming and E waste
13. Disadvantages
1. Requires a constant Internet connection.
2. Does not work well with low-speed connections.
3. Features might be limited.
4. Stored data might not be secure.
5. Stored data can be lost.
14. • Thus cloud computing provide a super-computing power .
• 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.
