How good is Ada though for something that most programmers might work on in their day to day ? Something like building a REST service ?
Well here’s the hello-world of a REST service in Ada.
If you’ve never seen Ada code before but you have built a web-service before, it’s fairly easy to make sense of this code. Now let’s look at the performance of this code on a mid-range desktop with an AMD Ryzen Threadripper 2950X.
Having built a few global-scale distributed systems in various languages at Amazon and AWS, getting this kind of performance and stability (9000 tps with 300 concurrent clients @ 99.9% success rate) on a single-machine so easily without having to sacrifice safety and security is rare. Even with such a simple example.

The name “Ada” is not an acronym; it was chosen in honor of Augusta Ada Lovelace (1815-1852), a mathematician who is sometimes regarded as the world’s first programmer because of her work with Charles Babbage. She was also the daughter of the poet Lord Byron.
