What is Cloud Computing?

17. CLOUD COMPUTING
17
Dr. NGPASC
COIMBATORE | INDIA
Cloud Computing is the use of network of remote servers hosted on the
Internet to store, manage & process data rather than a local server

18. CLOUD COMPUTING

Dr. NGPASC
COIMBATORE | INDIA
Cloud Computing
It is the delivery of computing
services (Servers, DB., N/W, S/W
etc.) over the Internet

23. PROPERTIES OF CLOUD COMPUTING
23
Dr. NGPASC
COIMBATORE | INDIA
Cloud Services
• Cloud storage - distributed resources - act as single unit
• Highly fault tolerant through redundancy - distribution of data
• Eventually consistent with regard to data replicas
• Collaboration in cloud

Dr. NGPASC
COIMBATORE | INDIA
• Cloud Computing - foundation of digital business
• Many organizations still struggle to optimize this powerful tool
• Gartner - less than one-third of enterprises have a documented cloud strategy

29. DEPLOYMENT MODEL
29
Dr. NGPASC
COIMBATORE | INDIA
• Public Cloud are exposed to the public and can be used by anyone
• Private Cloud used by single organization not exposed to the public
• Hybrid Cloud distributed among public & private clouds
 Sensitive applications kept inside the organization’s network (private
cloud)
 Other services can be hosted outside the organization’s network
(public cloud)
 Users can them interchangeably use private as well as public cloud
services in every day operations

31. PUBLIC Vs PRIVATE CLOUDS
31
Dr. NGPASC
COIMBATORE | INDIA
Terms Public Private
Tenancy Multi-tenancy: The data of
multiple organizations in
stored in a shared environment
Single tenancy: There’s only
the data of a single
organization stored in the cloud
Exposed to the
Public
Yes: anyone can use the public
cloud services
No: only the organization itself
can use the private cloud
services
Data Center
Location
Anywhere on the Internet - CSP
services located
Inside the organization’s n/w

32. PUBLIC Vs PRIVATE CLOUDS
32
Dr. NGPASC
COIMBATORE | INDIA
Terms Public Private
Cloud Service
Management
The Cloud Service Provider
(CSP) manages the services
The organization must have their
own administrators
Hardware
Components
The CSP provides all the H/W &
ensures it’s working at all times
Organization has to buy physical
servers to build the private cloud
Expenses The CSP has to provide the h/w,
set-up the application & provide
the network accessibility
according to the SLA (Service
Legal Agreement)
Can be quite expensive, since the
h/w, applications & network have
to be provided & managed by the
organization itself

33. PUBLIC Vs PRIVATE CLOUDS
33
Dr. NGPASC
COIMBATORE | INDIA
Terms Public Private
Others • Scalability is very high &
reliability is moderate
• Security matters & dependent
on service provider
• Performance - low to medium
• It has shared servers.
• Scalability is limited, and
reliability is very high
• It gives high class of security
• Performance is high
• It has dedicated servers
Examples Amazon web service (AWS) and
Google AppEngine etc.
Microsoft KVM, HP, Red Hat &
VMWare etc.

36. INFRASTRUCTURE AS A SERVICE
• It often provides the infrastructure as Servers, Virtual Machines,
Networks, Operating System, Storage & much more on a pay-as-you-use
basis
• IaaS providers offer VM from small to extra-large machines
• IaaS gives complete freedom for choosing the instance type as per the
requirements

39. PLATFORM AS A SERVICE
• PaaS model is similar to IaaS, but it provides additional tools like
DBMS, BI services etc.
• It provides elastic scaling - allows developers to build
application & services over the internet & deployment include
public, private and hybrid
