2. Remember the days when we used to store data in floppy disks? The present
day is different-with the advent of cloud, storage and access of data is no more
an arduous task. Whether it is big corporations or individuals, everyone is
leveraging the power of Cloud.
The impact of Cloud Computing is so high that, Forbes in its Cloud
Computing Forecasts projected it will witness an increase to $162B in 2020
from $67B in 2015attaining a compound annual growth rate (CAGR) of 19%.

4. What is Cloud Computing?
It was not very long ago when people had to maintain a pile of physical documents
which if lost or misplaced could cost a great deal. Cloud Computing has
transformed how the internet was used completely-enabling storing data in a
centralized location which can be accessed from computer and mobile device
anytime anywhere. Whether it is pictures, important data, now with the access of
cloud, sharing files has never been so easy. To sum up, Cloud literally acts as a
virtual drive or maybe more than that.

5. Cloud Computing Service Models
• Cloud services are based and categorized on three service models, namely- Infrastructure as a
Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).
• IaaS in cloud computing: The first layer of Cloud, IaaS or Infrastructure as a Service involves
delivering cloud computing infrastructure where third party providers such as Amazon Web Services,
Microsoft Azure or Google, hosts virtualized computing resources over the Internet.
• PaaS in cloud computing: Platform as a service (PaaS)- the second cloud layer is a cloud computing
model that enables delivering applications over the internet where a developer can easily create, run,
test and manage the applications over cloud.
• SaaS in cloud computing: SaaS or Software as a service is the third layer, which is also popularly
known as ‘on-demand software’, it is a software distribution model where applications can be hosted
centrally on the cloud server and can be accessed directly without downloading or installing.

6. Deployment Models in Cloud Computing
• Private Cloud: Provides its services exclusively to a single enterprise or institution. In
Private Cloud model the cloud infrastructure can be tracked only by the cloud provider
or the user.
• Public Cloud: In the Public Cloud model, the services and infrastructure remain open
to use for the general public. While the users have no control over the location of the
infrastructure, they can access the services over a public network such as the internet.
• Hybrid Cloud: This Cloud model is basically the amalgamation of both Public Cloud
and Private Cloud infrastructure where the particular enterprise or institution using it
can benefit in the aspect of attaining scalability, flexibility, and security.

7. Top Cloud Providers
• The popularity of Cloud is not only among businesses but also general users
that stimulated number of companies to provide cloud services in the recent
years. Today there are numerous cloud providers; however, there are handful of
them who are leading in the cloud market.
• Google Cloud Platform
• IBM Cloud Services:
• Amazon Web Services:
• Microsoft Azure:

8. Why take Cloud Computing Certification?
• Indeed’s search revealed that there are around 25,000 unfilled positions in the U.S. that are relevant to
AWS alone.
• According to the predictions by International Data Corporation IDC that the spending on public
cloud services and infrastructure is projected to exceed $277 billion by 2021 in an annual growth rate
(CAGR) of 21.9 percent.
• There is a rise of 33% in employers expressing interest in cloud computing skills.
• By 2022, the overall development in IT spending on cloud-based offerings will be faster compared to
the traditional (non-cloud) IT offerings- that will make cloud computing count as one of the most
disruptive forces in the IT landscape.
• For Cloud Engineers in India, the average salary as of 2019 is INR 12, 01,527 according to Glassdoor.
