2. Enter the cloud
Presented By: Rohit Sarkar & Kanishka Roy
A model for delivering information technology services in which
resources are retrieved from the internet through web-based tools and
applications on-demand, rather than a direct connection to a server. Data
and software packages are stored in servers. However, cloud computing
structure allows access to information as long as an electronic device has
access to the web. This type of system allows employees to work
remotely.
3. The Average Cloud user
Connects to the cloud via the Internet
Does computing tasks, or
Runs applications, or
Stores Data

Cloud Computing Services
Software as a Service (SaaS)-End UsersSoftware as a Service (SaaS)-End Users
Platform as a Service (PaaS)- Network ArchitectsPlatform as a Service (PaaS)- Network Architects
Infrastructure as a Service (IaaS)-Application DevelopersInfrastructure as a Service (IaaS)-Application Developers
6. Software as a Service-End Users (SaaS)
Also known as On-demand Service.
Is an application that can be accessed from anywhere on the world as long as
you can have an computer with an Internet Connection.
We can access this cloud hosted application without any additional hardware
or software.
E.g. : G-mail, Yahoo mail, Hotmail, Facebook etc..
Presented by: Rohit Sarkar& Kanishka Roy
7. Platform as a Service (PaaS)
In the PaaS model, cloud providers deliver a computing platform, typically
including operating system, programming language execution environment,
code deployment, database, and web server.
Application developers can develop and run their software solutions on a
cloud platform without the cost.
Some PaaS offers, to match application demand resources need not to be
allocated manually, so that the cloud user faces any problem. Required
services are provided by the vendor.
E.g.: Salesforce.com, Windows Azure etc.

8. Infrastructure as a Service (IaaS)
Also known as hardware as a service.
Is a computing power that you can rent for a limited period of time.
Allows existing applications to be run on a cloud suppliers hardware.
Cloud providers offer computational abilities and computers – as physical or
more often as virtual machines – raw (block) storage, firewalls, load
balancers.

10. Modes of Clouds
Public Cloud
• Computing infrastructure is hosted by cloud vendor at the vendors premises.
• 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.

11. The Cloud Requires
An Internet connection
An account - Created with a user name and a
password
Agree to Terms
Presented By: Rohit Sarkar & Kanishka Roy
12. So what is the cloud?
Computing and software resources that are delivered on demand, as service.

13. From ground to cloud
Presented By: Rohit Sarkar & Kanishka Roy
14. Computer Storage
Computers have internal or hard drive storage(C:
Drive)
CPU has a drive for storing programs, documents,
pictures, videos, presentations, etc…
Cannot access this content from another device or
computer
Central Processing Unit
(CPU)
Inside the Computer
Presented By: Rohit Sarkar & Kanishka Roy
15. Programs
Purchase programs
Load to the computer
Each computer would
need the program
loaded and stored on
the internal drive
Presented By: Rohit Sarkar & Kanishka Roy
External Storage
Allows your content to become
mobile
Save to the storage device
Take device to any compatible
computer
Open and use content
16. Networked Storage
Multiple work stations talk to one unit that stores
information and data.
Data is not saved to the C: drive, but to a network
drive
Can retrieve the data stored to the network from any
of the connected workstations.
Presented By: Rohit Sarkar & Kanishka Roy
17. Cloud Storage
Create an Account –
User name and password
Content lives with the
account in the cloud
Log onto any computer
with Internet to find
your content.
Presented By: Rohit Sarkar & Kanishka Roy
18. Downloads for storage
Download a cloud based app to a computer you own
The app lives on your Computer
Save files to the app
When connected to the Internet it will sync with the
cloud
The Cloud can be accessed from any device with
Internet connection.
Presented By: Rohit Sarkar & Kanishka Roy
19. Upload Documents
Log-in to the online storage account
Click upload a file
Find the file on hard drive, network, or external
storage
Upload to cloud storage
5 GB
5 GB
2 GB
7 GB
Presented By: Rohit Sarkar & Kanishka Roy
22. Download required?
Presented By: Rohit Sarkar & Kanishka Roy
One can even download the created document if the he wants.
Can also edit the document afterwards.
23. Benefits
Saving Large Files
Multiple file types – Photos, videos, presentations,
docs
Back-up of stored files
File Sharing
Access from devices
Nothing to forget (thumb drive, cd)
Project collaboration
Presented By: Rohit Sarkar & Kanishka Roy
24. File Sharing
Presented By: Rohit Sarkar & Kanishka Roy
We can share files if we want.
Or we share a link of a file to any recipient.
25. Other Software services
Photo editing software
Online banking apps
Social media apps
Communication
Presented By: Rohit Sarkar & Kanishka Roy
27. Advantages
Can be less expensive compared to buying software and hardware
Can be used from any computer or device with an Internet connection
The device does not need as large of an internal storage system
Compatible with most computers and operating systems
Updates occur across the service
Presented By: Rohit Sarkar & Kanishka Roy
Disadvantages
Sometimes they hike prices
Security and privacy in the Cloud
Technical Difficulties and Server failure
Limited control and flexibility
28. Cloud computing remains strong and has great
potential for the future. Its user base grows
constantly and more big players are attracted to it,
offering better and more fine tuned services and
solutions. We can only hope that the advantages
will further grow and the disadvantages will be
mitigated, since cloud computing seems to have
made IT a little bit easier.
Happy CLOUD COMPUTING!!!

I hear this question often. It is not easy to explain, because it means different things depending on who you talk to. Today’s Webinar will focus on the basics of what cloud computing is and what it means to the average library user and the library staff member.
I would bet everyone in attendance today uses the cloud. I am going to show a slide with several examples of cloud based applications. I would like you to count up how many from this sampling you use. I will then put up a poll question to get your answers.
Take the poll
Have you used the cloud
For one, two, three, or more of these services
The typical cloud software requires an account.
You are asked to fill out a form like the example here for Google Mail.
You also have to agree to the Terms of Service.
Raise your hand on the dashboard if you have checked agree to Terms of Service without reading.
Thanks for being honest. I highly recommend you go back and read those…you may learn some interesting things. The Privacy policies are also very revealing…check them out.
An Internet connection is necessary for cloud computing
The cloud is actually a bunch of computer servers that store and transmit data
These servers are very large and can hold massive amounts of data
The servers can be housed anywhere in the world
A user accesses the data through a log-in
To understand how we got into the cloud, you need to understand a little about computer storage.
We also use networked storage which is more commonly found in businesses and organizations.
Still internal to the organization
Each brand of cloud storage offers different levels of service. You can find your content and read it from any device with an Internet connection, but you may not be able to edit it from any computer.
Some of these services offer an app download that adds a storage folder to your computer. Some services require that you download the app.
I am curious to know how many people in attendance are using one of the types of cloud storage. I will launch a poll to get your input. I am also wondering what you like about the cloud storage service you use. Please type this response into the chat box.
We will keep using the same four examples to discuss applications, for sake of ease.
Some cloud storage services also offer document creation services.
Cloud storage allows you to share files with anyone. Files can be made public, for anyone to search and find or it can be shared with one person and you can decide if the people the file is shared with can view or edit the file.
