• 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.

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.

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.

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.

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

Why take Cloud Computing Certification?

• Indeeds 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.
• There are several dignified positions open for
  professionals with cloud computing skills,
  ranging from Cloud engineer to Software architect
  and Full stack developer to Development
  operations engineer, to name a few.
