Why move to cloud ?

If you need to move your application online 24 hours.Cloud is a better solution.
Suppose you are based in London and your clients are all in California.
You need your data server to be hosted in California instead of having a seperate server running 24 hours.
in California,with employees, Electricity cost you move to cloud,
In Cloud you can decide online how many cpu you need, you can also increase the memory with no down time if yu
have a application process which shall take time and you need to increase its performance.

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.

Also you can use it for training a particular software say a server requires minimum 33 gb ram and you need it for
understanding the particular working of the software.


Some of the important cloud providers are

Amazon Cloud
Rackspace Cloud
Profit bricks Cloud
azure cloud

Oracle has its own cloud solution.

Steps while building a cloud server
First you set your machine .
This involves deciding the memory,the numbers of core cpu,network ,hard disk capacity.
Once it is set you shall use a browser tool through which you shall connect to the the main machine.
The browser tool will require latest java version enabled.
Different cloud server has different solution to connect to the server.



Risks to consider before moving to cloud
What if internet is shut ?
Cloud outages.
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 website?
