This is Sysadmin Sunday, a post of interesting links from throughout the previous week.
- Using MySQL as a NoSQL – A story for exceeding 750,000 qps on a commodity server
- Googlenet traffic now 6% of interwebs – Google now handles more interwebs traffic than all but one of the world’s ISPs, after gaining more than one per cent of the net’s total traffic over the past nine months
- How To Use SSL To Secure Your Rails App Against FireSheep And Other Evils – protecting your site from Firesheep
- Scaling DISQUS To 75 Million Comments And 17,000 RPS – 100 servers; 30% web servers (Appache + mod_wsgi); 10% databases (PostgreSQL); 25% cache servers (memcached); 20% load balancing / high availability (HAProxy + heartbeat); 15% Utility servers (Python scripts)
- Overclocking SSL – If there’s one point that we want to communicate to the world, it’s that SSL/TLS is not computationally expensive any more. Ten years ago it might have been true, but it’s just not the case any more. You too can afford to enable HTTPS for your users.
- Free Content Delivery Network using DNS cache – Why spend money on expensive CDN hosting when there’s a perfectly good, free, global one available?
