Put your IT hardware in the cloud and focus on the data. I can create and support this cloud hardware. During my IT career the server rooms were often very large, especially for organisations with a mainframe. Today we can move all this hardware into the cloud, you don't need to maintain server rooms anymore. Amazon Web Services, Google Cloud Platform and Microsoft Azure offer cloud hardware which can store your data and run your applications. Some people have security concerns with cloud computing, but data security is logical using passwords and encryption. Companies that provide cloud hardware also claim to be physically secure. If you are concerned about the data's physical location maybe you should keep your own hardware so that you know where your data physically is, which machine it's on. However it remains data. Humans previously thought of security in terms of lock and key but now need to think cyber. Data security is never a certain thing with hackers but the companies that provide cloud hardware are also aware of the most recent threats and mitigations. You would also have such risks with your own physical hardware. Perhaps your data will be more secure with IT security professionals. Security threats and techniques are always changing, maybe in future we will use fingerprint authentication.
AWS Use AWS to replace your IT hardware with cloud hardware. Reduce cost leaving the maintenance and storage of such equipment to the experts. What's important is your data.
