  1. GENICloud

  2. Types of Clouds

  3. GENICloud Architecture

  4. Challenge 1: Security Policy • Experimenters have public-facing VMs • What can go wrong? • Sites have specific firewall policies

  5. Challenge 2: Availability • All types of failures • Machine room (nature, mechanical) • Expiring DHCP leases • Software problems • Obstacles to fast recovery • Distributed administrative domains • Restricted physical access • Default services turned off

  6. Challenge 3: Understanding Your Audience • Physical Hosts, Virtual Machines or Processes? • Custom images / hardware/ Kernels? • Performance isolation? Privacy? • How much scale do we need per host? • Do you care about the xyz interface?

  7. Challenge 4: Federation • Site-specific firewalls/proxies • International laws about content, liability • Sustainability

  8. Challenge 5: Miscellaneous • Naming • Rspec • Educating users / Documentation

  9. Naming Service <instance>.<slice>.<site>.geni-cloud.net boss.<site>.geni-cloud.org • Bind9 server at each authority • AM Sends updated list of instance.slice.site ex: foobar.myslice.hp.geni-cloud.net

  10. Best Practices / Lessons Learned • Framework for monitoring/accounting • Need to treat machines as throw-away • Leverage mature management software

  11. Questions – Chaos!! • On-node virtualization interface: containers vs. virtual machines. • What are the tradeoffs? • Security in GENICloud, including ABAC, • certs, • sign-on restrictions • Use of private networks • restrictions, and how do we use them • from machines connected to the public Internet? • Integration with OpenFlow: • what do we need • how do we do it?
