Open Standards and Open Source in Datacenter Management - OSDC.tw 2014
This document discusses open standards and open source tools for monitoring, managing, and provisioning datacenter resources. It provides an overview of tools like MRTG and Munin for monitoring network traffic and system resources. For management, it discusses IPMI for out-of-band server control and SSH for secure access. Provisioning tools mentioned include DHCP, PXE, kickstart/preseed for automatic installation, and Chef/Puppet for configuration management. The goal is to enable small teams to manage thousands of nodes hands-off using these open standards and tools.
