This is quick introduction to Cloud Computing & its Growth in India

1. Ver 1.0

2. What is Cloud ?
 cloud computing is a model for enabling ubiquitous,
convenient, on-demand network access to a shared pool of
configurable computing resources (e.g., networks, servers,
storage, applications and services) that can be rapidly
provisioned and released with minimal management effort or
service provider interaction.“ ( Source NIST )
Deployment Model:
 Public Cloud - Your IT infrastructure hosted in the Cloud
Service provider
 Private Cloud - Cloud orchestration in your private IT Data
Centre
 Hybrid - Combination of Public and Private Cloud, Typically
use as DR/BCP
 Community Cloud: Cloud Infrastructure shared between
multiple organization from a specific community with common
portfolio, Either hosted by third party and manage internally.

3. Service Model:
 Infrastructure-As-A-Service ( IaaS) : This is very basic form, Where provider
od Iaas provides Computers – Virtual machines & other resources which can
scale service up & down as per requirement. Cloud user install their
Operating System Images, application on top of it and maintain it.
 Platform-As-A-Service ( PaaS) : It provides computing platform with includes
operating system, Database, Web server & Programming language execution
enviroment. Developers can develop and run their application on top of this
cloud platform with no worry of managing underline hardware and software
layer.
 Software-As-A-Service ( SaaS) : This is one more step further where Cloud
service provider provides the software application to end user & typically
charge per user. In this Environment Cloud user just need basic network
connectivity to access their application in Cloud. All software, hardware
platform manage by the Cloud Service provider.

4. Cloud Computing Simple or Complex ?
 The main benefit cloud computing is on demand self service.
 The End users/Consumer can provision the computing capability
such as setting up a server, Attaching a storage, Configuring a
network, as needed automatically with out any technical support.
 Broad network access to cloud using any avilable end point with
network access.

5. Cloud & Virtualization
Cloud computing is not equal to Virtualization, But Virtualization
is your first step towards Cloud computing.
Cloud service are expensive ?
No, Pay as you use, which makes the Cloud computing cheapest
solution available in the world. e.g Server with 32 CPU, 244GB of
RAM Cost 2.8$/Hr & No need to pay when services are not
being use during Non business hrs.

6. Here to stay:
 Cloud is current generation big wave in IT industry & will stay for
decades
Transform:
Let it be Enterprise, Corporate, SME's They all will have to move
towards Clouds soon and get adapted at earliest.
New Jobs:
Cloud Computing will create 15 Million new jobs globally by 2015.
India Alone there will be 2 Million new Jobs created by 2015. Are
you ready?

7. Challenges and New Opportunity:
 Though cloud attract few million IT jobs and big cost saving to
company, There is also a debate, What will happened to
existing IT infrastructure, specialist and experts career path and
future?
 Bangalore is consider to be biggest IT support and services HUB
for the world, Cloud being game changer for many companies, it
will also change the way IT department operates.
 The traditional system administrator, storage admin & networks
engineer should use this opportunity to enhance their skill and
understand "titles" available in this cloud era to retain the career
on silent cloud tsunami.
 Evolution in cloud is being contributed by expert community so
the academic availability or learning opportunity is limited & one
has to develop if what is available.

8. Facts and Figures:
 The growth of cloud services varies by country and specific
cloud service type.
 India market is unique in that demand is consistently high
for all types of cloud services & there is tremendous growth
expected in near future.
 As per study, Public Cloud Services revenue in India will
reach near $1 billion by end of 2015.
 Spending on IAAS will total near $100 Million
 Business process as a service (BPaaS) is expected to grow
from $100+ million in 2014 to $350 million in 2018.
 SaaS is expected to grow from $246 million in 2014 to $707
million in 2018.

9.  Cloud computing Merged compute, storage & Network
infrastructure integration, It also contributed for fine & effective
Capex and Opex planning,
 It really saves great amount of time, Cost for any business needs.
 It simplifies the Planning, provisioning & Deployment of Data
Centre IT infrastructure.
 It would create new Job opportunity and Individual has to keep
them self updated with this technology.
 There is tremendous growth expected in near future.
 Cloud is a real evolution of this Millennium & Thanks to Amazon
for their contribution.
