I'm looking for something to supplement my fix for system design content from the high scalability blog. The last article[1] was 2 months ago, 6 months before that, 3 months before that. The irregularity of releases leaves me with withdrawal symptoms.
Each post there are multiple things that blow me away. Most recently, 9 on-prem web servers power stack overflow and all stack exchange sites. Then you drill into their source and get blow away again. They use 1.5TB memory SQL Server databases!
