Time warp 1996 Today
• The Internet had 20 million users in 1996 (most connecting via 14.4k or
28.8k dialup). Today in India alone there are 150 million households that
are connected.
• In 1996 the average user spent 30min / month online (today this is more
like 27hrs / month).
• The average household today creates more Internet traffic than the
entire Internet back in 1996.
• Today most people have a Terabyte of content in their homes (I-pod,
backup HDD, digital photos, thumb drives etc). In 1996 we had a 40MB
HDD and moved things around using a 1.44MB floppy disks.
• Evolution of online productivity (e.g. e-Commerce, You-tube, Social
Networking, real-time applications etc)

What’s my point?
• Initially the Internet was uncomplicated
• Over time our usage of the Internet has evolved
• Innovations are facilitating new online services/applications
• Users and consumers have expectations that they can complete tasks and transactions online
• Static infrastructures don’t accommodate change very well
• Customers are less responsive to demands
• Rapidly accelerating complexity
Right now there is a large shift towards
IT Agility for online applications

Challenges in Application Delivery
Enterprise application traffic flows both ways between every tier of the datacenter
These tiers are often designed/implemented individually
– Interoperability challenges
– Performance issues are hard to pinpoint
– Distributed architecture decisions

Control Point #5 – Web Application Performance
Previous Attempts
1. Fix application performance issues by upgrading network
2. Throw more bandwidth at it - the problem still exists?
3. Add more CPU and Memory
4. Add more servers
5. Add Quality of Service
6. Symmetric Acceleration - appliances on both ends of pipe
Why are web apps are still slow?… What about remote users?
7. Restrict the functionality of the application
8. Remove rich content

Use API calls to associate VM with vCenter in Site B.
During this transfer, GTM & LTM maintain connectivity to
VM. Since all new connections are routed directly to Site
B, and the old connections gradually bleed off, eventually
all connections are made directly into Site B. Process
complete.
GTM reroutes any new app connections/sessions
directly to Site B. Existing sessions are routed
indirectly through Site A to Site B until they complete.
VMotion VM from cloud 1 to cloud 2, using the same
iSession tunnel. vCenter A still in control.
