When Instagram joined Facebook in 2012, we quickly found numerous integration points with Facebook’s infrastructure that allowed us to accelerate our product development and make our community safer. In the beginning, we built these integrations by effectively bouncing through Facebook web…
Fascinating read. Infrastructure migrations don’t get much bigger, more complex, or more ambitious than this.
Today I learned that the total number of tweets ever made on Twitter is roughly 4x the total number of posts ever made on Tumblr.
The number of database servers they have is far, far more than 4x, and ditto for the number of staff members working on their databases. Also keep in mind the average Tumblr post is quite a bit larger than a tweet.
Not knocking Twitter by any means — their work is extremely impressive, especially their open source contributions. But given visibility into the raw numbers, I’m especially proud of the database work my former teams (tiny, tiny teams!) accomplished at Tumblr.
At no point did I move to California, or plan on moving to California, or ever state that I was moving to California.
If you see me, please stop asking me why I’m not in California or when am I returning to California. And most importantly, please stop telling other people that I moved to California. I have not moved to California.
