Building Elastic Infrastructures
summary
Claims an auto-scaling platform built from open source pieces that actually runs at scale: Flipkart Hostdb + Puppet with PXE autodiscovery and small agents. It provisions racks and VMs, auto-writes DNS and monitoring, and drives orchestration for 5,000 servers across two data centers. Components are simple, scriptable, in production for years, and agents either generate configs or fail safe so automation remains reliable.
