  1. Private Cloud at Wipro Cloud computing based on Condor

  2. Agenda Background Wipro Private Cloud System architecture Use of Condor 1 2 3 4

  3. Background • Need: • Share physical infrastructure between multiple projects and CoE's (Center of Excellence) to reduce server sprawl and number of physical labs • Provide an environment for evaluating new technologies, developing solutions and enabling collaboration between multiple labs • Centralize infrastructure procurement and management • Reduce infrastructure cost of CoE's by enabling multiple development environments • Solution: • Setup a private cloud for virtual compute and application infrastructure • Build a self-service portal for on-demand provisioning to reduce process overheads • Support multiple types of virtualization software • Reuse existing physical infrastructure, procure minimal new infrastructure

  13. Use of Condor

  14. Why Condor? • Trusty old features • Flexibility – ClassAd mechanism, configurations and policies • Web Services API • High availability • Resource utilization of jobs • Newer features we like • VM Universe • Partitionable Slots • Lease management • Integration with Amazon EC2 (public cloud) • Proven in large scale deployments • Condor-users and condor-admin support • Open source

  15. How are we using Condor? • Mostly standard configuration • A few custom class ads in jobs and machines • Schedd and Collector configured in HA mode • Condor spool for VM persistence • Virtual machine provision request handled by Condor • VM job to physical machine match-making, file transfer • Partitionable slots for dynamic partitioning of physical machine resources • Customized condor_vm_* files for configuring and starting VM's • VLAN control, Swap disk and additional storage creation, ... • Lease management for limiting the number of running instances of a licensed image

  16. Observations, Workarounds, Wish list • Working with Condor: • With advanced Condor skills, a lot can be achieved without modifying condor code Workarounds: • Passing number of virtual CPUs to VMware • Patch to pass proxy username and password to gSOAP for EC2 integration • Patch to get VM resource usage details on ESX • Special configuration to handle 2 hour delay in detecting a few execute node failures (Thanks Todd!) Feature wish list: • Remote IWD support for VM universe, to avoid any file transfer • Live migration of VM jobs
