Pranav Vashistha presented on cloud computing. He discussed basic concepts like traditional on-premise computing versus cloud computing. He covered first movers in cloud like Amazon, Google, and Microsoft. Pranav defined cloud computing and explained its components including clients, data centers, distributed servers. He described the three main cloud service models - Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Pranav also covered types of cloud, benefits like scalability and cost savings, and applications like storage and databases.

5. Traditional Approach
Few years ago-
• The user used to back up their data on storage disks. With
few advancements in technology, smart & handy devices are
created to store data on the go.
• To set-up a business successfully, you needed to invest on
setting up devices, technical staff, software & licenses. As
your business grows you need additional investments not only
for keep your business running but also for persisting changes
in technology.
• You need upgrades, renewal of licenses, additional staff for
managing the excessive amount of data.

Microsoft
• Windows Azure
• Microsoft SQL Services
• Microsoft .NET Services
• Microsoft SharePoint Services

7. Definition
Cloud Computing can be defined as a technique which enables
the web hosting service providers to provide their customer an
efficient self-service approach.
It integrates various applications, platforms, infrastructures &
services which can be shared by several people or businesses at
the same time.
It is a blend of communication networks, business applications
& IT resources which is basically implemented to cut off costs
,optimization & synchronization of various resources.

9. 1. Clients
• Mobile- Mobile devices like PDAs, Smart-Phones.
• Thin- Devices not having internal hard drives.
• Thick- Regular computer accessing through web browsers.
2. Datacenter
• It is the collection of servers where the application we subscribe are
housed.
3. Distributed Servers
• Servers are placed at different geographical locations to ensure that
in case of a failure, the service can be accessed from some other site.
Grid Computing is often confused with Cloud Computing, but they
are quite different. In grid computing, a large project is divided
among multiple computers to make use of their resources. Cloud
computing just does opposite. It allows multiple smaller applications
to run at the same time.

10. Cloud’s Service Models [1]
The services of a cloud includes the following traits:-
• Multitenancy
• Device Independency
• Large Scalability
• Low barriers to entry.
It includes the following three models of services:-
1. Software as a Service (SaaS)
2. Platform as a Service (PaaS)
3. Infrastructure as a Service (IaaS)

11. Software as a Service (SaaS)
Cloud Computing
11
In this model an application is hosted as a service to customer
who access it via the Internet. The idea is that you use the
software out of the box as is & do not need to make a lot of
changes or require integration to others systems, The provider
does all the patching & upgrades as well as keeping the
infrastructure running.

Platform as a Service (PaaS)
PaaS supplies all the resources required to build applications &
services completely from the internet, without having to download
or install software. It is also known as “Cloudware”. PaaS services
include:-
• Application Design
• Development
• Testing
• Deployment
• Hosting
• Database Integration
• Security
• Versioning

Cloud Computing
Infrastructure as a Service (IaaS)
It offers the hardware so that your organization can put whatever
they want onto it. Rather than purchase servers, software, racks,
& having to pay for the datacenter space for them, the service
provider rents those resources.
IaaS allows you to “rent” such resources as:-
• Server Space
• Network equipment
• Memory
• CPU cycles
• Storage space

Cloud Computing
Types of Cloud
The cloud computing services can be public or private. A public
cloud sells services to anyone on the internet. A private cloud is
a proprietary network. It is also a data center that provides
hosted services to a limited number of people. When public
cloud resources are used by a service provider to create their
private cloud, the result is called a virtual private cloud.
Private or public, the goal of cloud computing is to provide
easy admittance to computing resources and IT services.
Services can be anything from Web-based email to inventory
control, and database processing. Because the service provider
controls both the applications and the data, the user can use the
service from anywhere freely.

Applications of Cloud
Cloud computing brings us applications, a way of viewing,
manipulating & sharing data.
The basic applications include :-
1. Storage
2. Database
3. Synchronization
