A few years ago, we set out to rebuild server and log monitoring from the ground up. Today marks a new and exciting chapter in the story. To tell it properly, let me take you back to a simpler time: the year 2005.
I had just co-founded Writely — “The Web Word Processor!” — and usage was skyrocketing. We ran the whole thing on four leased servers in Texas. It was the clunkiest setup you’d ever seen, but there were few moving parts and it wasn’t much trouble to manage.
Within a year, we were acquired by Google, merged with a spreadsheet app, renamed “Google Docs”, and relaunched on Google infrastructure. The new system was infinitely more scalable, but quite complex. We depended on a slew of independent services: load balancing, data storage, user identity, email, spell checking, and more.
