Solution Workflow

1. Begin with application in private cloud only2. Ramp up application traffic until it exceeds performance threshold3 “Burst” to public cloud dynamically adding application nodes3. Burst to public cloud, dynamically adding application nodes

– Traffic management is globally balanced between private and public clouds

4. Continue ramping up traffic and expanding capacity in public cloud5. Decrease application traffic, contracting the application by

removing public nodes and eventually returning to steady state inremoving public nodes and eventually returning to steady state in private cloud

WAN Optimization Module™WAN Optimization Module™ Acceleration of VMotion and Storage VMotion

• F5 tested many different bandwidth/latency combinations

• Base Scenario:• 1 GB Virtual Machine• Windows & Linux Servers• Source host CPU 100% utilizedSource host CPU 100% utilized• 10 individual test runs averaged for each scenario• First Pass only (deduplication)

• SSL encryption

• AccelerationAcceleration– TCP Optimization– Byte-level deduplication

Dynamic compression– Dynamic compression

60

Requirements

• Duplicates in Primary & Secondary sites:– F5 BIG-IP Local Traffic Manager– F5 BIG-IP Global Traffic Manager– F5 BIG-IP WAN Optimization Module– LTM iRule collecting any TCP connections that arrive to primary site after VM has

been migrated, and forwards these connections to the secondary site.– vSphere, VMotion, Storage VMotion– Shared storage mounted via iSCSI or NFS that both ESX servers can mount

• TCP Ports 8000 (VMotion) & 443 (LTM) must be open• Guest IP & Network config (e.g. port groups) on hosts in migration must be

identicalidentical• For VMotion, VMware officially supports 622Mbps or higher WAN (type of

WAN is irrelevant)

Common Desktop Virtualization Challenges

• User Experience– Performance over the Wide Area Network– Access methods / complexityAccess methods / complexity– Login steps / annoyance

S it• Security– Encryption of all WAN traffic– Unified Access (Local vs. Remote, Desktop vs. Smart Phone)– Integration with existing authentication infrastructure– Endpoint integrity inspection

• Scalability/Availability– Scaling VDM servers without more power or rackspace– Ensuring total availability of connection brokers

VMware Recommends UDP Native Support

• Scott Davis, CTO End User Computing Business Unit• October 25, 2010• http://communities.vmware.com/blogs/cto-scott/2010/10/25/a-simple-experiment

• “There are numerous ways to configure such VPN’s, however PCoIP utilizes UDP for the graphics packets and optimizes parallelism and retransmits at the higher layers of th t l H d i VPN t h l th t t UDPthe protocol. Hence we recommend using a VPN technology that support UDP packets natively, not to tunnel the UDP traffic over TCP/IP as doing so will typically cause responsiveness issues…”

• Native UDP support is available in F5 FirePass and BIG-IP Access Policy Manager.
