We are providing computational capability for the future of urban transportation.The Compute Platform Team is building the orchestration layer for Uber’s datacenters. We runthe “private cloud” for Uber infrastructure, and our vision is to be able to run everything(including stateless, stateful and batch workloads) on a shared platform efficiently and reliably.The team brought container infrastructure to Uber and has drastically changed the way howapplications are run. Right now we are leveraging open source technologies and working on thenext generation of scheduling / containerization / automation solutions to manage massivelylarge datacenters.We’ve already built the foundational components of a cohesive, loosely coupled service-oriented architecture. What’s next is to build new infrastructure platforms on top of this groundwork and transition existing services to them. This architecture needs to propel us into a future of 10x growth — an infrastructure scale only few companies can boast of.
