By now we all know about cloud computing. As we speak of clouds, more and more clouds are moving into our lives with excellent services. With cloud computing exclusive access to programs and services from anywhere with Internet often without having to install other software makes it real efficient, and above all getting access to the services from any device capable of reaching the network is even more better. With this power are we actually ready for the costs that this virtual machine offers? It has been reported that at a cloud computing conference in New York, many experts pointed out that the cloud is moving past the hype stage and is beginning to bring more solid profit to businesses and it includes better agility. Because of these types of costs it actually don’t prevent companies from getting real worth out of cloud services however they will have an blow on the whole cost-benefit study of these computing services.

Transferring or storing information can cost many lakhs a year to shift large volumes onto public cloud services and to store for longer periods of time. Most organizations may not realize the charges as the unpredicted cost of transferring data is for network bandwidth, cloud providers might charge upload and download fees and other costs, including internal labor. “People think there are no labor costs, but as you scale up … handle workload, there’s a complexity with managing large numbers of cloud instances, just like managing a large number of servers,” says Hernan Alvarez, senior director of IT and operations at WhitePages Inc. Definitely another big cost is for long-term storage of data on the cloud.

Software testing is another major feature as all applications are not ready for the cloud which can further increase the costs for cloud users. So be ready for any unexpected testing or debugging for one of your vendor apps that had not been run in a cloud configuration before like checking versions of different OS and database compatibility.

What about some data “trust”. To keep your information secure, you want to protect your files from prying eyes while also preventing them from being lost or inadvertently destroyed. If your primary concern is making sure that nobody but you ever sees your data, the cloud may not be for you. While most reputable cloud services offer strong guarantees that your data will be heavily encrypted and that no one inside the company has direct access to your files, you can never be 100 percent certain that something won’t go wrong. Even when cloud burst, they often keep the server’s active long enough for customers to recover or delete their files. And then is the service reliability. However the answer to the Cloud service provider’s privacy and low cost is that your data is more vulnerable to loss by a fire or other unexpected calamity, and even a simple power outage can knock the device offline. So think about it!
