Partly because AWS give out a lot of free credit for start ups, and basically allow them to grow without planning any infrastructure. VCs who are invested into Amazon also wants to push the cloud narrative. Starts up who dont want to deal with servers, want massive scale when they think the website and later an app went viral.

That was in the late 00s and early 10s. PHP, Python, Ruby and even Java were slow. Every single language and framework has had massive performance improvements in the past 15 to 20 years. Anywhere from Java 2x to Ruby 3 - 10x.

When a server max out at 6 - 8 with Xeon core, compare to today at 192 Core. Every Core is at leats 2 - 3x faster per clock, with higher clock speed we are talking about 100x difference. Especially when IO used to be on HDD, SSD is easily 1000x faster. What used to wait for I/O is no longer an issue, the aggregate difference when all things added together including software could be 300x to 500x.

What you would need 500 2U server in 2010, you could now do it in one.

Modern web developers are so abstracted with hardware I dont think many realise what sort of difference in hardware improvements. I remember someone posted before 2016 Basecamp had dozens of Racks before moving to cloud. Now they have grown a lot bigger with Hey and they are only doing it with 8 racks and room to spare.

AWS on the other hand is trying to move more workload to ARM Graviton where they have a cost advantage. Given Amazon's stock price are now dependent on AWS, I dont think they will lower their price by much in the future. And we desperately need some competition in that area.
