The stark reality of cloud computing is that it is far from perfect and skeptics often cite reliability, security and privacy as some of their biggest concerns. Many of these challenges are already being addressed by cloud services providers, and as cloud technologies continue to be more widely adopted, they will inevitably evolve into being more usable, reliable and secure.
Cloud services aim to deliver 99.95% or higher availability. This translates to less than 5 hours a year of downtime. You would be hard pressed to deliver the same reliability with your own systems and staff. While outages do occur, it is important to factor redundancy and contingency plans into the mix where possible.
Security is certainly not a concern that is exclusive to the cloud, as practically any Internet connected system is fair game for a security breach. The idea of having your systems in a secure data center and under the watchful eye of dedicated IT security experts is certainly one advantage of being in the cloud.
Admittedly, the implications of cloud services on privacy can be a daunting task. If your organization needs complete control of its data or has very specific regulatory requirements, opting to create a private cloud may be a better option. You may also wish to consider choosing a cloud services provider whose terms of service can be adapted to your needs.
Getting more capacity in the cloud is as easy as flipping a switch. You won’t have to worry about the lead time to purchase a new server or install more storage because you can ramp up or downsize as needed to meet demand.
