ARM is cheaper on AWS per the unit of work done, in the general case. But there should be no assumption that ARM is that snappy little brother that will launch your lambdas in no time while x86 is still starting up, this is the kind of idea that I get when reading the comments mentioning ARM. It won’t launch your virtualized environment that noticeably faster. It’ll just do more work for less money, and 40% is probably not the figure that you’ll see in real life.

- pletnes 5y agoThe latency reduction might be worth more than the money saved on AWS, is what I’m thinking.

Including Twitter. To the point AWS are currently not meeting demands for those instances. Not every workload will benefits, but it certainly isn't a niche market.
- alberth 5y agoLet's be fair here, AWS in general is fairly expensive. So is it really a surprise that customers are clamoring to use a reduced priced (while equally performant) offering?
