CLOUD COMPUTING
3
Introduction
  • Generally a user need Applications, files ,
    videos, music, storage space, ebooks ..

4
Contd.
  • And user constantly faces a problem where to
    store , access these things
  • To come out off this problem we have a solution
    ie
  • CLOUD COMPUTING

5
In this session we learn
  • What is cloud computing?
  • How cloud computing works?
  • What are the pros and cons?

6
History
  • Concept evolved in 1950(IBM) called RJE (Remote
    Job Entry Process).
  • The idea of an intergalactic computer network was
    introduced in the sixties by J.C.R. Licklider,
    who was responsible for enabling the development
    of ARPANET (Advanced Research Projects Agency
    Network) in 1969.
  • One of the first milestones in cloud computing
    history was the arrival of Salesforce.com in
    1999, which pioneered the concept of delivering
    enterprise applications via a simple website. The
    services firm paved the way for both specialist
    and mainstream software firms to deliver
    applications over the internet.
  • In 2006 Amazon provided First public cloud AWS
    (Amazon Web Service)

7
Definition
  • The storing of data and applications on remote
    servers, and accessing them via the internet
    rather then saving or installing them on your or
    office computer.

8
Cloud Components
  • It has three components
  • Client computers
  • Distributed Servers
  • Datacenters

9
CLIENTS
  • Clients are the device that the end user interact
    with cloud.
  • three types of clients
  • 1.) Mobile
  • 2.) Thick
  • 3.) Thin (Most Popular)

10
Datacenter
  • It is collection of servers where application is
    placed and is accessed via internet.

11
Distributed servers
  • Often servers are in geographically different
    places, but server acts as if they are working
    next to each other.

12
Central Server
  • It Administers the system such as monitoring
    traffic, client demands to ensure everything runs
    smoothly.
  • It uses a special type of software called
    Middleware.
  • Middleware allow computer to communicate each
    other.

Third party / Middleware

How cloud computing works?
15
Service Models
  • SaaS(Software as a service) Required software,
    Operating system network is provided.
  • PaaS(Platform as service) Operating system and
    network is provided.
  • IaaS(Infrastructure as a service) just Network
    is provided.

Deployment of Cloud Service
18
Private cloud
  • A private cloud is a particular model of cloud
    computing that involves a distinct and secure
    cloud based environment in which only the
    specified client can operate.
  • However, under the private cloud model, the cloud
    (the pool of resource) is only accessible by a
    single organization providing that organization
    with greater control and privacy.

19
Contd.
  • Private clouds can be expensive with typically
    modest economies of scale.
  • This is usually not an option for the average
    Small-to-Medium sized business and is most
    typically put to use by large enterprises.
  • Private clouds are driven by concerns around
    security and compliance, and keeping assets
    within the firewall.

20
Public Cloud
  • The most recognizable model of the cloud
    computing to many consumers is the public cloud
    model.
  • Under which cloud serivces are provided in a
    virtualised environment, constructed using pooled
    shared physical resources, and accessible over a
    public network such as the INTERNET.
  • Public clouds, however, provide services to
    multiple clients using the same shared
    infrastructure.
  •  

21
Contd..
  •  Examples of public clouds include Amazon Elastic
    Compute Cloud (EC2), IBMs Blue Cloud, Sun Cloud,
    Google App Engine and Windows Azure Services
    Platform. 
  • For users, these types of clouds will provide the
    best economies of scale, are inexpensive to
    set-up because hardware, application and
    bandwidth costs are covered by the provider. 
  • Its a pay-per-usage model and the only costs
    incurred are based on the capacity that is used.

22
Hybrid cloud
  • A hybrid cloud is an integrated cloud service
    utilizing both private and public clouds to
    perform distinct functions within the same
    organization. 
  • Example TCS provides

23
Contd..
  • A leader in global network solutions, Tata
    Communications is uniquely positioned as the only
    telecommunications company with presence across
    six continents, the largest, wholly-owned subsea
    cable network, and more than 1,000,000 square
    feet of data centre space in 44 locations
    worldwide.

24
Community cloud
  • It  involves sharing of computing infrastructure
    in between organizations of the same community.
  • For example all Government organizations within
    the state may share computing infrastructure on
    the cloud to manage data related to citizens
    residing in that state.

25
Cloud Computing Architecture
  • It is comprised into two important parts FRONT
    END and BACK END which are connected by internet.

Cloud computing is
  • not only for storing data but is also
  • Inexpensive
  • Efficient
  • Flexible
  • Alternate to computers

29
ADVANTAGES OF CLOUD COMPUTING
30
You can access your data anywhere and at
anytime..
31
Example
  • User checks mail, only browser is in user side
    and the data related to mail is in cloud

32
Why to choose cloud computing for storage?
33
1. Cloud computing applications are LIMITLESS!
34
2. No need to buy high memory computers, simply
you need a device that is powerful enough, to run
a middleware needed to connect cloud system
35
3. No need to buy a software/ software license
for each employee in a company. If they pay fee
in cloud computing company they can use online.
36
4. No physical space is needed in the front end
tostore like servers, since cloud computing store
your data on their Hardware.
37
Limitations of cloud computing
38
SECURITY , COST PRIVACY

Contd
  • Requires a constant Internet connection. Cloud
    computing is impossible if you can't connect to
    the Internet. Since you use the Internet to
    connect to both your applications and documents,
    if you don't have an Internet connection you
    can't access anything, even your own documents
  • Doesn't 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 apps require a lot of bandwidth to
    download, as do large documents. If you're
    laboring with a low-speed dial-up connection
  • Can be slow. Even on 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

40
Contd
  • Features might be limited. This situation is
    bound to change, but today many web-based
    applications simply aren't as full-featured as
    their desktop-based brethren.
  • For example, you can do a lot more with
    Microsoft PowerPoint than with Google
    Presentation's web-based offering. The basics are
    similar, but the cloud application lacks many of
    PowerPoint's advanced features.

41
Contd.
  • Stored data might not be secure. With cloud
    computing, all your data is stored on the cloud.
  • How secure is the cloud? Can unauthorized
    users gain access to your confidential data?
    Cloud computing companies say that data is
    secure, but it's too early in the game to be
    completely sure of that. Only time will tell if
    your data is secure in the cloud.
  • Stored data can be lost. Theoretically, data
    stored in the cloud is unusually safe, replicated
    across multiple machines. But on the off chance
    that your data goes missing, you have no physical
    or local backup. (Unless you methodically
    download all your cloud documents to your own
    desktopwhich few users do.) Put simply, relying
    on the cloud puts you at risk if the cloud lets
    you down.
