Great Introductory Video on Scalability from Harvard Computer Science

Professor David Malan gives a very good lecture on scalability for dynamic websites. It's not highly technical, it's an extension course, but it's a great introduction to a wide variety of topics. I really like his teaching style. He continually asks questions, prompts for input, and gives accessible explanations. Some of the topics covered: vertical scaling; horizontal scaling; PHP acceleration; load balancing: DNS, L7, sticky sessions, load balancers; caching; MySQL: replication, load balancing, partitioning, high availability.

This is one lecture in a series of 13 lectures on building dynamic websites. Students learn how to: build dynamic websites with Ajax and with LinuxApacheMySQL, and PHP (LAMP); set up domain names with DNSstructure pages with XHTML and CSS how to program in JavaScript and PHPconfigure Apacheand MySQL; design and query databases with SQL; use Ajax with both XML andJSON build mashups.

For the lecture notes go to the OpenCourseWare site.

This is a great video, but it's still pretty basic stuff. In my opinion, scalability is mostly interesting when it is designed into your app. But I'm a software developer, that's why :-) All the scaling mentioned in this video is done outside the app = outside my domain.

Awesome lecture, I'm filing some of these scalability techniques away for use at my job.

It's decent for a beginning video. Everything covered is theoretical, and he has not actually applied this himself in any real world scenarios.

It sounds all academic. Nothing actual.

This lecture is almost 3000% better than everything taught on german universities...
