Cloud Foundry
 What is Cloud Foundry?
• Cloud Foundry is an open platform as a service, providing a choice of clouds,
developer frameworks and application services. Cloud Foundry makes it faster
and easier to build, test, deploy and scale applications. It is an open source
project and is available through a variety of private cloud distributions and
public cloud instances.
 How can I use Cloud Foundry? Cloud Foundry is available as:
• An open source project where developers and community members can
collaborate and contribute to the project
• A complete version of Cloud Foundry that runs in a virtual machine on a
developer’s Mac or PC (Micro Cloud Foundry)
• Multiple hosted instances provided by Pivotal and partners
• An on-premise software edition provided by Pivotal (coming soon)

Operating A Service – Common Priorities
 Uptime
• If running a cloud service, it must be available
• Some amount of downtime is to be expected so applications must compensate
 Manageability
• Modular – multiple types of components in a pre-defined unit of measure
• Isolated – one type of component in a pre-defined unit of measure
 Performance
• Shared (Limit) – unknown minimum and known maximum
• Dedicated (Reservation) – known minimum and potential maximum
 Scalability
• Scale-out – more resources only
• Scale-out + Redistribution – more resources and spread out the load

10. 10
Operating A Service – Non-priorities
 Hardware configuration and protocols
• Server versus blade
• 2-socket versus 4-socket
• FC versus iSCSI versus NFS
 Really does not matter
• Cost
• Requirements

11. 11
Public vs. Private vs. Hybrid Cloud
 Every cloud has advantages and disadvantages
 Benefits of leveraging multiple types of clouds
 Requirements, requirements, requirements
• Uptime
• Manageability
• Performance
• Scalability

12. 12
Cloud Foundry v1
Our experiences running cloudfoundry.com

13. 13
Cloud Foundry – Intensive Tasks
 Cloud Foundry Upgrade
• Cloud Foundry performs upgrades 2-3x per week. During an upgrade, a
portion of the environment is impacted, while the majority of the environment
can remain online
• The architecture must be able to support the upgrade with VM response times
achieving acceptable latency in order not to disrupt users which are still online
• The upgrade must complete within published maintenance windows
 Health Manager Restart
• The Health Manager service is responsible for keeping applications alive and
ensuring that if an application crashes then the processes it ran are restarted
• Latencies must remain within acceptable limits in order not to impact the
environment during this process
 Replication
• In order to support a DR strategy, a replication solution must allow for quick
recovery and minimal impact to the environment while protecting data

14. 14
Cloud Foundry – Testing
 Workloads tested
• Stemcell upgrade and downgrade with 10,000 “bad” applications
• Restart 20 applications with 512 instances of each application
• Failover to another datacenter
 Scenarios tested
• Storage goes offline
• ESXi host goes offline
• vCenter Server goes offline
• Disaster recovery

Cloud Foundry – Observed Storage Characteristics
 IO sizes vary
• 4KB predominant
• 128KB
• 256KB
 Mostly random with some sequential patterns
 Bursty for small periods of time (< 20 seconds)
• Ex. 3.5x more IOPS needed in 10 seconds
 Mostly writes
• 20/80 - Read/Write Ratio

VMware Private Cloud Advantages

21. 21
High Availability and Disaster Recovery

22. 22
Physical
 Achieve higher than three 9s availability
• Meet enterprise SLAs
• Components with low failure rates
 HA Built into the components
• No need to design into the application
 Disaster Recovery
• Site-to-Site protection
• Robust failover mechanisms
• Consistency for applications

23. 23
Virtual
 HA
 FT
 SRM
• SRM does not support vCloud Director!
• True, but other ways exist (e.g.
http://blogs.vmware.com/vcloud/2012/02/overview-of-disaster-recovery-in-
vcloud-director.html)

25. 25
Performance and Scalability

26. 26
Physical
 Meet specific IO SLAs
 Tenancy control
 Intelligent features
• Caching
• Automated tiering
• Non-disruptive volume migration
 Ability to quickly mitigate performance issues
 Easier to scale all or specific parts of the underlying infrastructure

27. 27
Virtual
 Resources
• Add hosts
• Add storage
• Add networks
• Hot-add
 Provisioning
• Linked clones
 VMware
• HA enhancements (master/slave)
• Storage enhancements (ATS, VAAI, VASA)
• Multiple clusters to provider VDC (VCD)

28. 28
Cloud
 Resources
• Pools
• Tiers
 Software-defined
• Complete blue prints (vCloud Automation Center)
• Complete workflows (vCenter Orchestrator)
• API driven components (Nicira / NSX)

Predictable IaaS Operations

30. 30
Overview
 IaaS controls the performance of the PaaS
 What does your infrastructure give you?
 Is performance consistent?
 Are certain operations faster/slower than others?
 Do things happen as you expect?
“Many things can be said about vSphere and its API, but it is very consistent in
response times, and it hardly ever lies to you.” – Martin Englund
(http://blog.cloudfoundry.com/2013/06/18/dealing-with-eventual-consistency-in-
the-aws-ec2-api/)

31. 31
Physical
 Customization
• Leverage best practices
 Redundancy and HA
• Redundant components
• Automatic failover
 Efficiencies

• Remote

32. 32
Converged Infrastructure
 What is converged infrastructure?

unit of delivery
• Examples: Vblock, FlexPod, VSPEX
 Advantages of converged infrastructure
• Time to deployment
• Simplification of management
• Lower TCO
• Improved utilization
• Known fault domains
• Determinist performance and capacity

33. 33
Virtual
