Berkeley DB Architecture - NoSQL Before NoSQL was Cool - High Scalability -
Absolutely, BerkeleyDB is amazingly fast if your scenario is a non-sharded single web server. I've used BerkeleyDB on BookMooch.com for 6 years, and real-world query speeds of 2 million queries per second, for a single web page, are typical. Those aren't simulated speeds: that's real world, after locking, overheard, etc... That kind of speed lets me use BerkeleyDB in place of in-memory arrays, and
The Design of 99designs - A Clean Tens of Millions Pageviews Architecture - High Scalability -
99designs is a crowdsourced design contest marketplace based out of Melbourne Australia. The idea is that if you have a design you need created you create a contest and designers compete to give you the best design within your budget. If you are a medium sized commerce site this is a clean example architecture of a site that reliably supports a lot of users and a complex workflow on the cloud. Lar
How Twitter Stores 250 Million Tweets a Day Using MySQL - High Scalability -
Jeremy Cole, a DBA Team Lead/Database Architect at Twitter, gave a really good talk at the O'Reilly MySQL conference: Big and Small Data at @Twitter, where the topic was thinking of Twitter from the data perspective. One of the interesting stories he told was of the transition from Twitter's old way of storing tweets using temporal sharding, to a more distributed approach using a new tweet store c

Stack Overflow Makes Slow Pages 100x Faster by Simple SQL Tuning - High Scalability -
The most common complaint against NoSQL is that if you know how to write good SQL queries then SQL works fine. If SQL is slow you can always tune it and make it faster. A great example of this incremental improvement process was written up by StackExchange's Sam Saffron, in A day in the life of a slow page at Stack Overflow, where he shows through profiling and SQL tuning it was possible to reduce
Netflix: Use Less Chatty Protocols in the Cloud - Plus 26 Fixes - High Scalability -
In 5 Lessons We’ve Learned Using AWS, Netflix's John Ciancutti says one of the big lessons they've learned is to create less chatty protocols: In the Netflix data centers, we have a high capacity, super fast, highly reliable network. This has afforded us the luxury of designing around chatty APIs to remote systems. AWS networking has more variable latency. We’ve had to be much more structured abou
What the heck are you actually using NoSQL for? - High Scalability -
It's a truism that we should choose the right tool for the job. Everyone says that. And who can disagree? The problem is this is not helpful advice without being able to answer more specific questions like: What jobs are the tools good at? Will they work on jobs like mine? Is it worth the risk to try something new when all my people know something else and we have a deadline to meet? How can I mak
Product: Scribe - Facebook's Scalable Logging System - High Scalability -
In Log Everything All the Time I advocate applications shouldn't bother logging at all. Why waste all that time and code? No, wait, that's not right. I preach logging everything all the time. Doh. Facebook obviously feels similarly which is why they opened sourced Scribe, their internal logging system, capable of logging 10s of billions of messages per day. These messages include access logs, perf
Flickr Architecture - High Scalability -
Update: Flickr hits 2 Billion photos served. That's a lot of hamburgers. Flickr is both my favorite bird and the web's leading photo sharing site. Flickr has an amazing challenge, they must handle a vast sea of ever expanding new content, ever increasing legions of users, and a constant stream of new features, all while providing excellent performance. How do they do it? Site: http://www.flickr.co
Amazon Architecture - High Scalability -
This is a wonderfully informative Amazon update based on Joachim Rohde's discovery of an interview with Amazon's CTO. You'll learn about how Amazon organizes their teams around services, the CAP theorem of building scalable systems, how they deploy software, and a lot more. Many new additions from the ACM Queue article have also been included. Amazon grew from a tiny online bookstore to one of the
