A description of how we built Open Cloud System (OCS), an OpenStack-powered complete cloud operating system. With a focus on AWS and GCE interoperability, we describe why hybrid cloud interoperability matters and how we got there. Anyone can do it and we think you should too.

 Like AWS (and GCP) Randy Bias, Founder & CEO! OpenStack Juno Design Summit! May 14th, 2014 @randybias OpenStack’s future is hybrid to public clouds!
  • 2. Who OpenStack Foundation Board of Directors! ! Scale Builder:! 100k+ sq ft datacenters @ 14MW! 1000s of servers, 100s of switches! ! Prod. OpenStack pioneer, Cloudscaling:! Part of OpenStack community since July 2010 (launch)! Firsts:! OpenStack Public Compute Cloud in U.S., Public Storage Cloud in U.S. and KR! ! Top 10 Cloud Computing Pioneer 2
  • 3. A Leader in Production Deployments* 3 * e.g. Currently actively supported clouds; legacy clouds from PS days are not included (multiply by 2-3x if you care) supported clouds total cores total storage 10+ 8,000+ ~8.5PB total servers ~600 # of Fortune 15? 2
  • 4. Today’s Goals Why an AWS-like “elastic” cloud?! Hybrid Cloud Interoperability! AWS Flavored OpenStack! Bring It Home 4 1 2 3 4
  • 5. Why Elastic Cloud?
  • 6. Top Clouds Are Elastic 6
  • 7. Epitomized by AWS/GCE! Scale-out model over scale-up model! Small failure domains! Foundation for Cloud Native Apps! Apps that “route around failure”! Manage own data replication/redundancy! Automated deployments! Economics are King! Open source software! Vanity-free commodity hardware! Low-cost, scale-out networking 7 What is an Elastic Cloud? For more information see the Chicago DevOps presentation at http://tinyurl.com/elasticcloud!
  • 8. Elastic Cloud is a Mindset Change 8 Attribution: Bill Baker, Distinguished Engineer, Microsoft bowzer.company.com (pets) web001.company.com (cattle) Cloud is the era of the disposable server vs.

 ➡ cost of experimentation and agility drives innovation As cost ➡… consumption
  • 12. Why Should the Enterprise Care? “Seventy percent of the companies that were on the Fortune 1000 list a mere 
 10 years ago have now vanished – 
 unable to adapt to change … ”! ! ! — Forrester analyst Craig Le Clair* 12 * SOURCE: http://blogs.forrester.com/craig_le_clair/13-09-09-make_business_agility_a_key_corporate_attribute_it_could_be_what_saves_you
  • 13. OpenStack: For ALL Clouds 13 Although … the best fit is elastic cloud Metering / Billing Platform Elastic Private / Public Cloud PaaS Platform Storage Platform OpenStack! Components Cloud App Mgt Framework
  • 14. Hybrid Cloud Enables Biz Agility Top public clouds are elastic! Elastic clouds have similar attributes! essentially they share a “reference architecture”! Agility is primary value for enterprise! Cloud native apps + DevOps drive agility! they “route around failures”! Elastic cloud is ideal platform for these apps! doesn’t matter if it’s private or public! Businesses need choice -> hybrid cloud 14 1 2 3 4 5 6
  • 15. Hybrid Cloud Interoperability
  • 16. Hybrid Cloud Value Proposition 16 Application Portability ~ Independence! Move apps between clouds with impunity! Advanced capabilities such as Cloud-bursting/bridging! Future-proofing and reduction of vendor lock-in! Pick the right cloud for the job!! Portability Requires Interoperability! API compatibility is a subset of what is required!! Interoperability Is NOT Easy! (details to follow)
  • 17. Pub Cloud Interop Matters 17 Private Clouds Must be Interoperable with Public Cloud Leaders OpenStack’s Future is Hybrid

 and Availability Guarantees VM uptime (hypervisor availability) API endpoint availability Storage system availability Performance & 
 QoS Guarantees VM vCPU, networking & local storage performance Block storage system performance matching Object storage aggregate throughput Infrastructure 
 Feature Parity Must have a majority of same primary features AWS -> EC2, S3, EBS, VPC, ELB GCP -> VMs, persistent block/object, virt. networks, etc. Similar Cost Economics & Economies of Scale Within ½-2x of wholesale costs/pricing TCO must be similar, particularly for operational costs API Compatibility Support for public cloud APIs At the least: AWS, GCE, Azure, and OpenStack Behavioral Compatibility Implied, non-API behavior is same or similar example 1: VMs start in <30 mins example 2: floating/elastic IP auto-assignment 1 2 3 4 5 6

  • 31. Behavioral Compatibility Testing Implicit non-API behavior crucial to test! We have already been testing it w/ Tempest! Tempest has a pretty sweet set of AWS tests (see next)! Some of them are turned off by default! OpenStack default settings don’t pass it seems! Cloudscaling has created more! Ultimately we need exhaustive Tempest AWS behavioral test suite! Then GCP, then Azure 31 6
