Why move data to the cloud ?

With the evolution of the cloud platform, Enterprises are moving data from their private data centers to platform offerings and Software Services offered on signup of Azure Cloud platform.

1. Why are small / medium / large enterprises moving to the cloud?

Cloud computing is continuing across a host of industry sectors as more and more organizations recognize the benefit, this movement can offer.  

Main benefits of cloud technologies are

1.1 Fully utilized hardware

Cloud computing brings natural economies of scale. The practicalities of cloud computing mean high utilization and smoothing of the inevitable peaks and troughs in
workloads. Your workloads will share server infrastructure with other organizations' computing needs. This allows the cloud-computing provider to optimize the hardware needs of its data centres,  which means lower costs for you.

1.2 Lower power costs

Cloud computing uses less electricity. That's an inevitable result of the economies of scale.  Better hardware utilization means more efficient power use. When you run your own data center, your servers
won't be fully-utilized (as you would be catering to peak traffic when that occurs). Idle servers waste energy. So a cloud service provider can charge you less for energy used than what you're spending in your own data center.

1.3 Lower people costs

Staffing budge often attribute a significant chunk to the computing costs as good human resources are expensive. When you move to the cloud, some of the money you pay for the service goes to the provider's staffing costs. But it's typically a
much smaller amount than if you did all that work in-house. Yet again, we have to thank: economies of scale. Redeploy your scare valuable IT resources to areas that can make more money for the business.

1.4 Zero capital costs

Buying servers, provisioning and configuration is a lot of effort and money. Though the costs are distributed through the expected years, upfront costs are sizable. With cloud infrastructure, you could start off with only a fraction of
the upfront costs

1.5 Resilience without redundancy

It is impossible to buy just the required hardware. It is quite a cumbersome processes to procure and add additional compute and storage. So IT departments usually start with spare hardware which would last for a year or two. This is
an expensive way to maximize uptime. Letting the cloud computing service to deal with redundancy, High Availability is an easy and comparatively inexpensive solution.

1.6 Bonus benefit: climate change

Many organizations want a greener foot print and include measures to offset their carbon foot print.  First, you are saving on energy with the economies of scale and secondly the service provider would
find it easier to put measures in place for greener planet.
