 BOSH CloudStack CPI
What we have done so far (1/2)
 NATS cluster
 More services
• Hadoop-as-a-service
• Create a Hadoop cluster on the fly
• Jasper-as-a-service
• Jasper Reporting as a service
• Mule-as-a-service
• Integrate Mule as a CF component
• Cassandra-as-a-service

7. 7
 Push CF into production
• Intensive Testing：
• Functional Testing(YETI)
• Stress Testing
• Destructive Testing
• Replace the Ruby router in v1 with Go router
• Make the deployment process aware of topology
What we have done so far (2/2)

We Update Bosh Agent for CloudStack to
get
1 . Address of Registry Endpoint
2. OpenSSH-Key
3. Network Settings
4. Data Disk path
Setup Chroot
We add a firstboot script to get the Nat
Gateway (Virtual Router)’s IP
