Yes I read your blog and it seems like you've written plenty of shell scripts and utils to try and abstract and automate away infrastructure, but it feels a lot like you are trying to re-invent the wheel when all of this and much more is available in major cloud providers as a service. One item that stands out for me is that your backup is a couple of shell scripts and you mention that you would dump your database to a different RAID array. That means you are now on the hook to procure/rent, manage, update and monitor that RAID array. And you even call out that you don't include offsite backups so you are at risk of total loss because you are using a single physical site for your prod data AND backup data. You mentioned above that you are "not locking myself in proprietary frameworks" - but in the process you have built custom one off scripted systems that are bespoke. If you leave or your consulting engagement ends it will be very hard for someone to take over and manage and maintain your systems - because your design, configuration and implementation is effectively lock in to YOU as a person and your consulting company. Personally I would rather trust a cloud provider to offer something like backup as a service where they can handle geographic replication, snapshots, restores for me as a service and deal with all the hardware, disk replacements, hardware monitoring and network fun that comes with it. The human cost of moving to another cloud provider is not that large and I can easily hire a person or consultancy that has knowledge of Cloud Provider A and Cloud Provider B to make that transition because their services and systems are well documented, conform to a contract and there are training and certifications for how they work. I still hold my opinion that taking advantage of services offered by cloud providers is value add in the context of running a business. Also I would much rather trust a cloud provider with a big team of security experts to run my infrastructure than a random company renting me some servers. If you are getting them as a service then there is still a shared admin control plane, likely management type networks and infrastructure around it that are managed for you by a third party. Trusting their team, processes and security capabilities is a very high bar to meet.
