Challenges with previous load balancer
First experience with Avi
Migration concerns/considerations
No disruptive strategies for migration
Benefits realized after migration
Agenda

4. ©2020 VMware, Inc. 4
200+ LTMs/GTMs Legacy F5 Infrastructure
500+ requests per month for load balancing modifications
• Add/remove pool member, change priority
• New LTM vip/GTM wip
• Most requests were completed manually using tmsh commands
Incidents from manual changes were common
4-6 month backlog of requests
Banking Customer - Background

5. ©2020 VMware, Inc. 5
Manual load balancer configs, high volume of requests
Banking Customer - Challenges That We Needed to Solve
Trouble Tickets
Caused by Manual
Changes
Complex Load
Balancer
Configurations
Huge backlog took 6-8
weeks for app deployment
Manually provisioned all
load balancer configs
Miscommunications
created incident tickets
Miscommunication between
app & LB teams
What can be done?

FinTech Customer – From Legacy LB to Modern Application Services
• Two physical appliances deployed in
Active/Standby HA
• Shared Control/Data plane on same hardware
• Control Plane resource limitations due to
sharing
• Event notifications : SNMP Traps and Syslog
• Metrics Gathering: SNMP Polling
• Manual Horizontal Scaling
• Service Impacts when Scaling
• Inflexible deployment, VIP tethered to physical
hardware
• Metrics rolled up to device level
• Troubleshooting requires obtaining Network
Operations resource
• Use cases requiring custom scripting; iRules
• Service Engine (software LB) pool dispersed amongst ESXi cluster
members, Active/Active
• Separated Control Data plane
• Independently scalable Control Plane with dedicated
resources
• Event notfications : SNMP Traps and Syslog
• Metrics Gathering: Rest API
• Automatic Horizontal and Vertical Scaling
• Zero Service Impact Scaling
• Flexible deployment, VIP is able to float and migrate between
Service Engines
• Advanced metrics and analytics down to the VIP level
• Analytics/Visibility allows for AppOps to be able to
troubleshoot without involving NetOps.
• Majority of iRule use cases are native configurations; VIP ACLs,
content switching, redirections
From – Legacy LB To – Avi

Migration Process Life-Cycle
Automated config
conversion
 Select apps for migration
 Review existing LB configuration
 Identify config conversion strategy /
methodology
 Perform config conversion &
optionally import the same
 Onboard converted configuration
Customization
 Create complex application policies & profiles,
convert iRules / traffic manipulation rules &
perform other advanced configuration
customization like custom monitors, pool group
associations etc.
 Onboard additional or customized configuration
(Optional)
Validation and
functional testing
 Verify imported configuration
 Identify cutover & rollback strategies
 Verify health-monitor operations
 Perform application functional testing
Consulting Pre-Sales Project planning
and scheduling
 Kick off meeting
 Team identification
 Migration project plan
proposal & acceptance
 Infrastructure readiness
assessment
Cut-over/Go-Live
 Perform application traffic
cutover
 UAT and sign-off from
application owners &
other associated teams
 Release system to end
users
Pre-Sales Program governance

Migration Experience and Best Practices
 Migrated 10,000 virtual services from the F5 LTMs to Avi via self-service offerings to the app owners.
 Reduction in the wait time for implementation from ~8 weeks to same day. Non-prod implementations
typically completed in under 10 minutes from customer submission.
 App owners started using the analytics/logs to troubleshoot their own issues, reducing incident
volumes.
 Define the support process early, who will handle an incident if automation breaks during a
migration?
 Document, document, document! An hour spent documenting the process to use the automation is
at least 10 hours saved answering user questions.

The bank experienced:
• A 60% reduction in change-related incidents. All incidents caused by the automation were the
result of user error.
• Bottom line savings of roughly $2 million per year in labor costs related to load balancing
implementations. Some load balancer platform engineers were able to transfer to more
rewarding automation or architecture work.
• Reduction in the wait time for implementation from ~8 weeks to same day. Non-prod
implementations typically completed in under 10 minutes from customer submission.
• Happier users, happier management.
