7. F5 Products used
• LTM used in 5 of our ten datacenters
– Corporate HQ

– Disaster Recovery/Internal environments
– Austin Datacenter replacing Netscalers
• Waltham datacenter will be converted to use LTM
• Virtual LTM being considered for lab environments
• Other datacenters will be consolidated
• We use WhiteHat and looking into ASM

8. How we load balance
• Round Robin
– Stateless applications virtuals/cloned
– until products have issues or need persistence
• Dynamic methods
– Observered member/node
– Depends on the number of pools
• Priority Group Activation
– Prefer to have at least 3 servers per pool (n+2)
– 1 Cron Server, 2 web servers
– Weblogic Reverse Proxy 3/6
– WP1 Pools 1/1/1

9. Persistence
• Universal
– iRule, jsessionid
• Cookie
– Default insert and tried passive
• SSL Persistence
– when using Client and Server SSL profiles
• Source IP
– Bad, but we still do it in places (easy)

10. iRule Lessons learned
• iRule Editor
– Now has bigip.conf and bigip_base.conf
– Offline iRules
• iRule naming convention, versioning
– TCP Connection
• iRule HTTP Events Flowchart
• TCL Errors
• Scripted bigpipe iRule changes
– bigpipe virtual rule diffs before/after
– Version 9 vs. version 10 changes (grep rule)
– Postfix to email/page upon differences

11. iRules used to solve problems
• .NET/SQL application upgrade split
– Using classes, switch glob
– Akamai challenges
• Company name change/combination
– Almost 1000 lines, nested if and switch
– Allows URLs to remain hosted on the same servers (3+
versions)
• Maintenance Pages
– Allow class of IP addresses through for QA validation
– Static/dynamic responses and redirects (client name changes)
– robots.txt, Google site verification
– Graphics/icons with hex conversion
• Block/Allow
– URL, IP user-agent, HTTP verb, etc.
,
– Faster and easier than firewall changes with our vendor

12. iRules used to solve problems (cont.)
• Referer replace
• Server Resource Cloaking
– Removing Server headers
– BigIP noserver
• Apache Killer prevention (range headers)
• TS-Edge JavaScript injection
• Load Balance Failure
• Low-cipher detection
• Mobile/iPad application redirect
• CAAMS pool switching
• AUS Throttling users (using stats profile)
• Pool Member Status
– From DevCentral (upgrading to Joel Moses’ version)

13. iRules and Mmmm cookies
• Akamai Cookie
– Prevents bypassing Akamai
– Secures/restricts resources by IP
– Not using Akamai’s site shield, so iRules and Akamai
configuration must be in sync
• QA Test cookie
• eLearning cookie
– Validate users
– Referring host switch directs to appropriate
resource
– Allows a single VIP to host all of our environments
• Home Cookie Clean
• VMS Cookie Crumb Clean

14. Other things we are doing with LTM

• WAN/LAN optimization
• Reviewing TCP and HTTP profiles for more
improvement
• Fix slow connectivity with Chrome (bug)
• Health Monitors
– Receive String
– Session creation

15. What is our plan going forward?
• Gomez Real User Monitoring
– Implement via iRules
• Priority for iRules
• Splunk
• Upgrade to version 11
• iApps/iControls
• Implement Partitions?
