[No PHPun Intended] A Brief History of Web Development
(nophpunintended.com)
Yep, PHP is turning 30 this year! Wondering if "PHP is still relevant?" Ever since we have been hearing that PHP is dead. It was “dead” 10 years ago, 5 years ago, and “is dead” today. But somehow - it isn’t. Anyway... happy birthday!
What if those chains handle thousands of massages per second?
Serious backend is indeed a stretchy term. And I agree with that point b2b java is common. But our b2b backend handles multiple thousands of massages per second. I find the bottleneck to be MySQL and RabbitMQ.
I think it makes sense for a serious backend to have load balancing and nginx cache and horizontal scaling. I reckon QPS doesn't matter as much as you think it does.
I still don't think that java would be considered niche. I rather think that C or C++ would be considered niche. It takes longer to develop, and is not memory safe so I don't think that most backend systems should consider it.
