Twitter 新機房,以及數據...

Twitter Engineer Blog 上的「The Great Migration, the Winter of 2011」這篇文章裡提到了 Twitter 預定搬機房的行程,裡面有些數據...

目前維護的人數:

Today, the feed and care of Twitter requires more than 200 engineers to keep the site growing and running smoothly.

機器數量超過 1000 台:(用 thousands 這個詞)

Simultaneously, our operations engineers divided into new teams and built new processes and software to allow us to qualify, burn-in, deploy, tear-down and monitor the thousands of servers, routers, and switches that are required to build out and operate Twitter.

Tweet 的資料量:

Once we proved our replication strategy worked, we built out the full Twitter stack, and copied all 20TB of Tweets, from @jack’s first to @honeybadger’s latest Tweet to the second data center.
