`
`Uber’s driver and rider numbers around the world have been ballooning, and so has its
`revenue. The mobile ride-hailing company has also been expanding into adjacent
`markets, such as scooters and food delivery.
`
`Along with all that growth comes demand for data center capacity to handle all the data
`flowing between driver and rider smartphones and the company’s computing network.
`To make sure Uber can scale its infrastructure on pace with demand growth, Dean
`Nelson, its executive in charge of infrastructure, has been making rounds on the data
`center conference circuit, explaining Uber’s needs to potential data center builders.
`
`Head of Uber Compute did this first in June, at Datacloud Europe in Monaco. His
`second appearance came this Monday at DCD London, where in a keynote presentation
`he once again outlined the company’s infrastructure strategy and the basic parameters
`of a standard Uber data center, according to DCD, the event’s producer.
`
`RECENT
`
`Like most young companies that have scaled quickly, Uber has been using a mix of
`cloud services and commercial data center providers to host its data.
`
`Per DCD:
`
`They call this ‘the tripod strategy:’ “It is not on-prem versus cloud, it’s not an or,
`it’s an and. When you get to scale, you have volumes where you can get to price
`performance that rivals cloud. But you can’t move like cloud can, we want to be
`able to say ‘turn it up’ and they have massive scale to do that immediately.”
`
`Nelson hasn’t said which cloud provider or providers Uber has been using. As he
`explained, the top cloud providers’ global scale enables their customers to expand into
`new territories (Uber is now in almost 80 countries) or increase capacity in existing
`ones quickly.

`Once a customer reaches certain scale, however, it starts to make financial sense for
`them to deploy their own data centers. In Uber’s case that means leasing facilities from
`data center providers, which the company then fills with its own computing equipment:
`
`
`
`Said Nelson:
`
`“The thing that has kept me up for the last two years is keeping up with this
`demand. Every forecast has been wrong, it’s been too small. The ability for us to
`leverage the best of and the speed of the cloud, but the price of on-prem is a
`really big strategic advantage.”
`
`Because of that cost advantage, most Uber data center workloads are hosted in the
`company’s own data centers, he said. Today, those data centers are in the US, according
`to Data Center Frontier, but Nelson wants to expand dedicated Uber infrastructure to
`Latin America, Europe, the Middle East, North Africa, and Asia-Pacific.
`
`RECENT
`
`His goal is to get to tens of regions – three data centers per region – and 100s of
`availability zones (single sites). Availability zones can be edge sites far away from core
`regions, deployed to improve application performance for local users.
`
`Nelson outlined some very specific basic requirements for a standard non-edge Uber
`data center he’d like developers to build for him. Each site should provide 5MW of
`power across 10,000 to 15,000 square feet of space to accommodate 576 IT racks.

`capacity it expands in (a single Uber pod is 16 racks), and a single data center fits 30
`such pods. That’s 480 racks. There are also 32 networking racks and 64 to be ready for
`the unexpected.
`
`
`
`Uber has separate racks for compute, database, various storage tiers, and GPUs (used
`for machine learning).
`
`According to a photo of one of the slides Nelson displayed at DCD, the company uses
`Apache Mesos, the open source compute cluster management system, in its compute
`racks; the Apache Cassandra open source database; and the Apache Hadoop open
`source distributed storage framework for “warm storage” (it also has a cold storage
`tier).
