Cloud computing is a type of Internet-based computing that provides shared computer processing resources and
data to computers and other devices on demand.
Oracle Cloud is the industry's broadest and most integrated public cloud.
It offers best-in-class services across software as a service (SaaS), platform as a service (PaaS), and
infrastructure as a service (IaaS), and even lets you put Oracle Cloud in your own data center.
Why move to cloud ?
The payment charge is subscription based and also the payment charge is monthly and cheaper
comparing to server licensing cost
First advantage is also the machine .The machine can be running 24 hours
and also you can be saving on electricity cost etc .
Supose you have a proecss and you need it to be run quickly
Or you need your application to run on a different operating system
with huge amount of memory
Instead of buying a systme you can run your application in cloud.
The cloud pc memory or cpu power can be increased .
Suppose you need your data to be present every where
You can put the data in cloud .. Once in cloud it can be acessed any where.
A software running on cloud can be made easily available on internet
and so people from multiple branches can acess the data.
You are billed monthly for the cpu power and memory
You need a central store where you store your data acessible by every user and devices cloud is a better solution.
You can use your cloud machine to check performance of a software with a particular hardware configuration.
Only for the test shall the machine be remotley available.
You need to test how the appplicatio nwill perform with huge memeory lets say 32 gm ram,etc
It can helped me in reducing the licensing cost .The payment is monthly basis so its easy

Risks to consider before moving to cloud
What if internet is shut ?
No entity is 100% safe from some type of disaster or emergency.
In fact, a powerful storm in June of 2012 knocked out an entire data center which was owned by Amazon.
What was hosted in that data center? Amazon Web Services.
All affected AWS businesses in that data center were effectively down.
Cloud-centric companies like Instagram, Netflix, and Pinterest were all made production ineffective for over six hours.
To paint a clearer picture, there was a recent study conducted by the International Working Group on Cloud Computing Resiliency.
This report showed that since 2007, about 568 hours were logged as downtime between 13 major cloud carriers.
This has, so far, cost the customer about $72 million.
In case your cloud machine has been impacted by malware or
by hackers the bandwidth can be robbed and also that
can increase your cost.
Considering Backup and restore of data in cloud.?
You might have the backup in cloud machine but what if you need the data in your server or your personnel machine?
Underestimating the time and bandwidth required to move large data sets.
Setup and administration of storage is getting easier every day, but network speeds are more limiting.
The more data moving in and out of the data center on a daily basis, the higher the bandwidth charges could be
depending on the provider and pricing plan. Plus moving just 1 TB of data into the cloud could take anywhere from
minutes to hours to days, depending on the company connection. Often times for large data sets we’ll request that
customers send hard drives with copies of data directly to the data center.
For example, what if cloud is breached?
Can cloud administrators see confidential data?
What if the cloud provider goes out of business or has a disaster of their own?
These questions, and more, must be addressed. Customers therefore need to think
about the security and control measures to mitigate these risks.
Ideally, they need a solution that’s easy to deploy and transparent to business users,
but doesn’t require a huge IT investment to implement. Essentially, they must plan for the unexpected.
What if hacker is able to get your cloud account ?
Do you have facility to have your data encrypted ?
Does your cloud support two factor authentication?
Do you have a method to check suspicious ip address logging your application?
Do you have a effecient Data migration strategy?
