Brown Bag Cloud Architecture “Eco-System” Notes

So I checked out the Brown Bag over at Cody’s Site. I have to say I was very happy with the Cloud Architecture.  It definitely was a different spin to learn about the “Eco-System” and also listen to some of the questions.  Here are the notes I gathered:

  • vSphere which was once the management layer is now more of an application layer
  • vSphere administrators may not be vCloud
  • Architecture shows best practice to have two vCenters one for the Cloud Service the other for management.
  • Automation and Orchestration is more important
  • Different security levels for Cloud and vSphere Management
  • Scaling the cloud out brings additional complexity to traditional virtual BU/DR technologies
  • Most scale-outs of the cloud involve more of use case versus meeting the vCenter maximums.
    • BU/DR requirements
    • PCI Compliance (Particular Security Use-Case)
  • VCD Database is still not “officially” supported when running Oracle RAC in “Active/Active” only “Active/Standby” Configurations
  • Templates are simply “powered off” VM in VCD
  • Network Copy happens between Clusters (different storage)
  • Cloning has always been Block-File copy between host (VAAI Helps)
  • For VCD deploying vApps to the assigned tenant datastores the vApps will deploy on datastores that has the least amount of “USED” space
  • VCD requires DRS – NEVER disable it
  • Linked Clones do not have mis-alignment on NFS
  • NFS seems to be gaining more momentum for VCD deployments

The following to me seemed to make a lot of sense.  I attempted to sort it out by what I would think is needed versus highly recommended.  Need is more of vCloud is dependent on that technology.

  • High availability of certain components – applications.
    • vShield Manager > FT enabled (Fault Tolerance)
    • vCenter Server > Heartbeat (More critical because VCD uses vCenter)
  • Components Needed to use in the Cloud Architecture (VMware Specific)
    • vCenter (one for management and the other for cloud)
    • vShield Manager
    • vChargeback
  • Components Highly Recommended:
    • vCloud Service Manager
    • vCenter Update Manager
    • vCloud Connector
    • vCenter Orchestrator
  • Future Products that will be vCloud ready:
    NOTE: Due to the different API’s in each Product, VMware is playing catch up on getting some of these products “vCloud Ready”

    • vCenter Ops
    • Infrastructure Viewer
  • Skill and Knowledge increase is also needed:
    • vSphere / ESX
    • Deeper Storage Skills
    • Deeper Networking & Firewall Skills
    • Scripting (PowerCLI)
    • Workflow / Automation
    • Capacity Planning

Note: Prior it was ESX, vCenter and some scripting
it is also more about Infrastructure Management now

Cell Network Considerations:

  • Network Design of Interfaces:
    • HTTP/Console Proxy (Front-End end-user aka Portal)
    • OS Management
    • Database (Oracle or MS-SQL)
    • NFS (Transfer Service Storage L2 Network with Jumbo Frames)
    • vSphere (L2 Network with Jumbo Frames)

Note: This is not referenced in the architecture but just recommendations. These may require static or additional routes. Traditionally this has been 2 interfaces. Use VLANS if possible. The NFS and vSphere are mostly for the cloning process or Import/Export processes of VCD. This would allow the cloud to be even more scalable and efficient.
