Later this year, Twitter is moving our technical operations infrastructure into a new, custom-built data center in the Salt Lake City area. We’re excited about the move for several reasons.
First, Twitter’s user base has continued to grow steadily in 2010, with over 300,000 people a day signing up for new accounts on an average day. Keeping pace with these users and their Twitter activity presents some unique and complex engineering challenges (as John Adams, our lead engineer for application services, noted in a speech last month at the O’Reilly Velocity conference). Having dedicated data centers will give us more capacity to accommodate this growth in users and activity on Twitter.
Second, Twitter will have full control over network and systems configuration, with a much larger footprint in a building designed specifically around our unique power and cooling needs. Twitter will be able to define and manage to a finer grained SLA on the service as we are managing and monitoring at all layers. The data center will house a mixed-vendor environment for servers running open source OS and applications.
Importantly, having our own data center will give us the flexibility to more quickly make adjustments as our infrastructure needs change.
Finally, Twitter’s custom data center is built for high availability and redundancy in our network and systems infrastructure. This first Twitter managed data center is being designed with a multi-homed network solution for greater reliability and capacity. We will continue to work with NTT America to operate our current footprint, and plan to bring additional Twitter managed data centers online over the next 24 months.
