All of us have at least some data stored in the cloud. Most of us still have servers locally or perhaps in local data centers or redundant areas all over the world. The process we use when the server is on-premises is usually the same as the process we use in the cloud, but the risks and responsibilities in the cloud are different.
If you have ever wondered what a data center is like, and the protective measures that suppliers take to ensure data security, please check out this virtual tour of the data center. A saying that people often quote is that the cloud is just another person’s server, which is true to a certain extent, but the reality is that the cloud is more than just a server. It provides physical protection, such as access control and monitoring who brings which content into the data center. The physical security level is usually higher than the level we provide for local storage. When we get closer to the data, we can get less protection, but our cloud provider cannot do that. Multiple customers share the same space and may have different risks and needs.
Local server security and data center security
My local server does not have the standard level of backup generator or grid redundancy that most data centers consider. For example, the day before, the local power company needed to perform electrical work on the electricity meters in our area, which required us to turn off the power on that day. We shut down all local computers and servers in the building because the backup battery and power supply will not last for the expected downtime of 12 hours.
