Cloud is not a technology advancement. Its only a shift of location. Whatever software running in a premise, can be shifted to cloud. Its a inevitable shift, nobody can stop that. Lot of money is involved in Cloud Structure. But the main issue is they own our "Data". Whatever NDA are signed, events happens in leakage of Data. Although thats a different topic altogether, but this is happening. Its like putting the human memory data in the "Cloud of Universe". Whoever made this system, the data is safe in the Akashik Records, however we have forgotten the "Password". Most of the people cannot access their own memory beyond the current lifetime. Similarly if something happens in the cloud, we lost the data. I give you an example. I created a mail ID, the person was also using the mail ID without any problem. His mail data was kept as a copy on Cloud storage. When the person left, we deleted the mail ID and tried to recover the Data from the cloud. Whew!! 70% of the mail data was missing. Something went wrong in the cloud. This is what is happening in many cases. People are ignorant, having less knowledge. The cloud owner person/company who maintains the Data suffers from the same disadvantage. If I can lost the data, cloud can also lost. And the real fact is nobody is responsible. If we cannot recall our past life, to whom we can blame ? Same thing happens. They say, your fault or they do not reply.
