> The vast majority of the BBC’s webpages are rendered on AWS, using React. React’s isomorphic nature allows us to render the pages server-side (for best performance) and then do some further updates client-side.

> Increasingly, the rendering happens on AWS Lambda. About 2,000 lambdas run every second to create the BBC website; a number that we expect to grow

That's the piece of information I miss in a lot of those stories. What happened X years later? We all love reading about strange projects, but it's not until someone sits down and writes a blog post about some old, custom system that you get the important insights (X was good, Y didn't work because reasons and nobody ever understood Z).

Sadly so. Still Perl around the organisation though in internal systems from that era which continue to work and still in daily use for producing news if nothing else.

I believe about 10-years ago they moved to PHP. They were one of the biggest PHP shops in the UK when I left the UK 8-years ago.
