It’s like putting something in someone’s desk drawer under the guise of convenience at the expense of security.
Why?
Too often, someone other than the data owner has or can get access to the drawer directly or indirectly.
Also, Cloud vs self hosted to me is a pendulum that has swung back and forth for a number of reasons.
The benefits of the cloud outlined here are often a lot of open source tech packaged up and sold as manageable from a web browser, or a command line.
One of the major reasons the cloud became popular was networking issues in Linux to manage volume at scale. At the time the cloud became very attractive for that reason, plus being able to virtualize bare metal servers to put into any combination of local to cloud hosting.
Self-hosting has become easier by an order of magnitude or two for anyone who knew how to do it, except it’s something people who haven’t done both self-hosting and cloud can really discuss.
Cloud has abstracted away the cost of horsepower, and converted it to transactions. People are discovering a fraction of the horsepower is needed to service their workloads than they thought.
At some point the horsepower got way beyond what they needed and it wasn’t noticed. But paying for a cloud is convenient and standardized.
Company data centres can be reasonably secured using a number of PaaS or IaaS solutions readily available off the shelf. Tools from VMware, Proxmox and others are tremendous.
It may seem like there’s a lot to learn, except most problems they are new to someone have often been thought of a ton by both people with and without experience that is beyond cloud only.
