Disclaimer – This is a live blog from the CloudStack Collab Conference. Might have a bunch of errors in formatting, etc.  I’m just typing as fast as I can.  Also, I work for Citrix and I focus on CloudPlatform, the commercial version of CloudStack.  Just want to be up front with everyone

Title: What’s the use Case by Paul Angus @ ShapeBlue

  • Use Cases: Test & Dev (of course), Highly Scalable public facing applications, high speed server resource deployment, anytime there is reduced reliance on corporate infrastructure teams
  • First One: create replicas of production environment, create replicas on the fly
  • This environment is cloned, used for development, then Q&A, then it becomes production
  • The code isn’t moved, the environment is moved
  • This is a media site
  • 10 million unique visitors per month, average of 833 million page views, CloudStack environment is in development
  • This use case has very time sensitive use cases, when are people looking at site, peaks at predictable times of the day
  • Scaling is happening as the data goes up and down
  • Two physical sites, here is the logical architecture:

  • RightScale is also used govern between an AWS environment and a internal environment, time based today during predictable patterns
  • Second One: overseas gambling site
  • The key here is environment templates, rolls out Tomcat, NOSQL, new app to develop – creation, destroy, very easy
  • They use Chaos Monkey & Simian Army to test the environment

  • Very fast transitions from development to production
  • Every thing is automated to flip from one to the other
  • Third Customer: Satellite Broadcaster in UK
  • VERY LARGE environment
  • They had a problem, they wanted multi-tier applications, traffic through the VPC routers wouldn’t stand up to traffic
  • Solution, created tiers with policies and broke traffic down into a better flow more than just in/out
  • Another issue – they want everything to be as fast as possible, no network hops if possible, looking into affinity and anti-affinity rules in upcoming release to solve this problem

  • Bursting to Amazon – Requires VPN/direct link to maintain database consistency, change rules in the load balancers
  • Feature Requests – What are customers asking for?  More Strage options, Kerberos, RBAC, better affinity / anti-affinity / vApps concepts, public/private cloud integration, security groups in Advanced Zones, multiple VLANS with SG separation, post deployment actions without virtual router DHCP
