Half a companies lifetime isn't a "<small number> of years ago" for that company. You can't compare tech ecosystems today to those in 2010, so many things has gotten standardized since then, Google was at the forefront back then.

Unlike modern companies Google had to build out everything themselves since nobody had built those systems or even had experience building such systems. That takes time, but today all of the things Google learned is common knowledge in papers and similar.

If you disagree mention one company that had a one button script that abstracted away things like where the data is stored to ensure failsafe, data replication etc, in 2010. I don't think there was any, just the fact that Google made it relatively easy to launch such services, just that you had to manually configure the replication script and the zones your data should be stored in wasn't really a big deal.
