Tumblr lets you effortlessly share anything. From photos to videos, the Tumblr dashboard has been the place for you to experience new and exciting content from the Internet. We'll be talking about different services we have built and how our architecture helps us be fault tolerant as we continue to grow. We'll discuss how we've scaled our engineering teams to deal with this growth across several verticals. We'll be going in-depth on how Tumblr uses several key pieces of technology, such as MySQL, Memcached, HBase and Redis, and what efforts were required to maintain those terabytes of data, all while delivering the best possible product for users.
