2 0.34242466 1329 high scalability-2012-09-26-WordPress.com Serves 70,000 req-sec and over 15 Gbit-sec of Traffic using NGINX

Introduction: This is a guest post by  Barry Abrahamson , Chief Systems Wrangler at Automattic, and Nginx's Coufounder  Andrew Alexeev. WordPress.com  serves more than 33 million sites attracting over 339 million people and 3.4 billion pages each month. Since April 2008, WordPress.com has experienced about 4.4 times growth in page views.  WordPress.com VIP  hosts many popular sites including CNN’s Political Ticker, NFL, Time Inc’s The Page, People Magazine’s Style Watch, corporate blogs for Flickr and KROQ, and many more. Automattic operates two thousand servers in twelve, globally distributed, data centers. WordPress.com customer data is instantly replicated between different locations to provide an extremely reliable and fast web experience for hundreds of millions of visitors. Problem WordPress.com, which began in 2005, started on shared hosting, much like all of the  WordPress.org  sites. It was soon moved to a single dedicated server and then to two servers. In late 2005, WordPress.com

Introduction: This is a guest a post by Alvaro Videla describing their architecture for Poppen.de , a popular German dating site. This site is very much NSFW, so be careful before clicking on the link. What I found most interesting is how they manage to sucessfully blend a little of the old with a little of the new, using technologies like Nginx, MySQL, CouchDB, and Erlang, Memcached, RabbitMQ, PHP, Graphite, Red5, and Tsung. What is Poppen.de? Poppen.de (NSFW) is the top dating website in Germany, and while it may be a small site compared to giants like Flickr or Facebook, we believe it's a nice architecture to learn from if you are starting to get some scaling problems. The Stats 2.000.000 users 20.000 concurrent users 300.000 private messages per day 250.000 logins per day We have a team of eleven developers, two designers and two sysadmins for this project. Business Model The site works with a freemium model, where users can do for free things like:  Search

Introduction: Our last article on Disqus:  How Disqus Went Realtime With 165K Messages Per Second And Less Than .2 Seconds Latency , was a little out of date, but the folks at Disqus have been busy implementing, not talking, so we don't know a lot about what they are doing now, but we do have a short update in  C1MM and NGINX by John Watson and an article  Trying out this Go thing . So Disqus has grown a bit: 1.3 billion unique visitors 10 billion page views 500 million users engaged in discussions 3 million communities 25 million comments They are still all about realtime, but Go replaced Python in their Realtime system: Original Realtime backend was written in a pretty lightweight Python + gevent. The realtime service is a hybrid of CPU intensive tasks + lots of network IO. Gevent was handling the network IO without an issue, but at higher contention, the CPU was choking everything. Switching over to Go removed that contention, which was the primary issue that was being se

Introduction: nginx is a high performance smtp/pop/imap proxy that lets you do custom authorization and lookups and is very scalable. (just add nodes) Nginx by default is a reverse proxy and this is what it is doing here for pop/imap connections. It is also an excellelent reverse proxy for web servers. Advantage: You dont have to have a speacial database or ldap schema. Just an url to do auth and lookup with. A url that may be accessed by a unix or a tcp socket. Write your own auth handler - according to your own policy. For example: A user called atif tries to login with the pass testxyz. You pass this infomation to a URL such as socket:/var/tmp/xyz.sock or http://auth.corp.mailserver.net:someport/someurl The auth server replies with either a FAILURE such as Auth-Status: Invalid Login or password or with a success such as Auth-Status: OK Auth-Server: OneOfThe100Servers Auth-Port: optionalyAPort We have implemented it at our ISP and it has saves us a

Introduction: A man had a dream. His dream was to blend a bunch of RSS/Atom/RDF feeds into a single feed. The man is Beau Lebens of Feedville and like most dreamers he was a little short on coin. So he took refuge in the home of a cheap hosting provider and Beau realized his dream, creating FEEDblendr . But FEEDblendr chewed up so much CPU creating blended feeds that the cheap hosting provider ordered Beau to find another home. Where was Beau to go? He eventually found a new home in the virtual machine room of Amazon's EC2. This is the story of how Beau was finally able to create his one feeds safe within the cradle of affordable CPU cycles. Site: http://feedblendr.com/ The Platform EC2 (Fedora Core 6 Lite distro) S3 Apache PHP MySQL DynDNS (for round robin DNS) The Stats Beau is a developer with some sysadmin skills, not a web server admin, so a lot of learning was involved in creating FEEDblendr.

1 0.94385666 1033 high scalability-2011-05-02-The Updated Big List of Articles on the Amazon Outage

Introduction: Since The Big List Of Articles On The Amazon Outage  was published we've a had few updates that people might not have seen. Amazon of course released their  Summary of the Amazon EC2 and Amazon RDS Service Disruption in the US East Region . Netlix shared their Lessons Learned from the AWS Outage  as did Heroku ( How Heroku Survived the Amazon Outage ), Smug Mug ( How SmugMug survived the Amazonpocalypse ), and SimpleGeo ( How SimpleGeo Stayed Up During the AWS Downtime ).  The curious thing from my perspective is the general lack of response to Amazon's explanation. I expected more discussion. There's been almost none that I've seen. My guess is very few people understand what Amazon was talking about enough to comment whereas almost everyone feels qualified to talk about the event itself. Lesson for crisis handlers : deep dive post-mortems that are timely, long, honestish, and highly technical are the most effective means of staunching the downward spiral of media attention.

Introduction: Please see The Updated Big List Of Articles On The Amazon Outage  for a new improved list. So many great articles have been written on the Amazon Outage. Some aim at being helpful, some chastise developers for being so stupid, some chastise Amazon for being so incompetent, some talk about the pain they and their companies have experienced, and some even predict the downfall of the cloud. Still others say we have seen a sea change in future of the cloud, a prediction that's hard to disagree with, though the shape of the change remains...cloudy. I'll try to keep this list update as more information comes out. There will be a lot for developers to consider going forward. If there's a resource you think should be added, just let me know.

3 0.83898246 311 high scalability-2008-04-29-Strategy: Sample to Reduce Data Set

Introduction: Update: Arjen links to video Supporting Scalable Online Statistical Processing which shows "rather than doing complete aggregates, use statistical sampling to provide a reasonable estimate (unbiased guess) of the result." When you have a lot of data, sampling allows you to draw conclusions from a much smaller amount of data. That's why sampling is a scalability solution. If you don't have to process all your data to get the information you need then you've made the problem smaller and you'll need fewer resources and you'll get more timely results. Sampling is not useful when you need a complete list that matches a specific criteria. If you need to know the exact set of people who bought a car in the last week then sampling won't help. But, if you want to know many people bought a car then you could take a sample and then create estimate of the full data-set. The difference is you won't really know the exact car count. You'll have a confidence interval saying how confident

Introduction: How do you keep a system small enough, while still being successful, that a simple scale-up strategy becomes the preferred architecture? StackOverflow , for example, could stick with a tool chain they were comfortable with because they had a natural brake on how fast they could grow: there are only so many programmers in the world. If this doesn't work for you, here's another natural braking strategy to consider: charge for your service . Paul Houle summarized this nicely as: avoid scaling problems by building a service that's profitable at a small scale . This interesting point, one I hadn't properly considered before, was brought up by Maciej Ceglowski, co-founder of Pinboard.in , in an interview with Leo Laporte and Amber MacArthur on their their net@night show. Pinboard is a lean, mean, pay for bookmarking machine, a timely replacement for the nearly departed Delicious. And as a self professed anti-social bookmarking site, it  emphasizes speed over socializing . Maciej
