Please don't lecture on experience, it reeks of hubris. The fact the you suggest someone buys their own hardware to run a database to support their business is somehow cheaper shows a lack of understanding in regards to the difficulties companies face and the risks of managing a database inhouse.

You speak in absolute terms that are simply not true. Choosing DynamoDB as your datastore does not mean you have to pay Amazon forever. Databases can be exported successfully. Costs can vary dramatically so don't assume it will blow the budget.

Amazon has a large repository of documentation in regards to exporting data and there is huge online community for AWS support and third-party tools. If you are as experienced as you claim to be, you would know these are big factors when choosing a platform to serve your data.

These benefits along with an incredible array of services, reliability, security, ease of configuration, reduced licensing costs, scalability and support coupled with the wealth of talented people available who are well versed in AWS would be enough to persuade most companies towards this choice. Thus why it is the most popular choice to host data at the moment and why most companies are moving away from in house databases. Thats not an opinion, thats fact.
