Businesses across industries are fast adopting cloud. In addition to government organizations such as CIA/ NASA, verticals such as Healthcare, Banking and Financial Services which are known to give critical importance for data security, privacy and regulations too have been early adopters of cloud. However, there are businesses who are yet to take a step forward into cloud, essentially, not being able to overcome the cloud barriers or rather as I may call it “misconceptions”. Data security, data privacy, loss of control, and latency are some of the reasons why organizations hesitate to move to cloud. I would like to highlight a few points which shows why these features scores while storing data on cloud rather than storing data on-premise.
Let me start by asking how many cases of security breaches have you heard of, for data on cloud as compared to the data on-premise. The reason why security breaches on cloud is not as common as those that we see on-premise can be attributed to the fact that cloud security is in the hands of people who manage thousands of servers, who puts data security at the core of their business. In addition to this, from an enterprise perspective, location of data, regulations, choosing of vendors who provide flexibility of locating data within the region/ country is a big challenge in itself. There are cloud vendors who provide data location flexibility - choosing the right vendor depending on your data security needs and regulations is important.
Sometimes due to multi-tenancy, there are concerns on data privacy. However, there are vendors like Amazon who provide Virtual Private Cloud (VPC). Most of these cloud providers are compliant to privacy regulations like HIPAA which makes them adhere to strict rules.
Loss of control
It may appear that IT has lost the control over hardware by moving hardware to cloud and is no longer responsible for maintaining it. But this actually opens new opportunity for IT. IT can now better align to business and spend more time in understanding business requirement rather than spending efforts on provisioning and maintaining hardware.
Most of the cloud technologies run on technologies like MPP and have very high performance with a latency of micro seconds. For those requiring milliseconds of latency like the stock exchanges, they may need to have their servers close to their premises.
Driving my point further, there are multiple benefits that an organization can avail once it moves to cloud. Talking about space, it provides support for petabytes of data with elastic storage leading to skyrocketing data volumes. It also speeds up value realization leading to more revenue per year. It helps organization to cut down on operational cost and better utilize IT resources as it follows pay-per-use model making seasonal analysis worth their money. Also, it simplifies the entire process by focusing on business priorities and not worrying about procuring infrastructure and setting up data centers. It is self-sufficient in nature, provides fully managed services and provides an environment for innovation and prototyping.
