Developing iRules for BIG-IP

DESCRIPTION

This course provides networking professionals a functional understanding of iRules development. The course builds on the foundation of the Administering BIG-IP or Configuring LTM course, demonstrating how to logically plan and write iRules to help monitor and manage common tasks involved with processing traffic on the BIG-IP system. Extensive course labs consist of writing, applying and evaluating the effect of iRules on local traffic. This hands-on course includes lectures, labs, and discussions.

Target Audience

This course is intended for system administrators, network administrators and application developers responsible for the customization of traffic flow through a BIG-IP system using iRules.

Duration: 3 Days

Course Topics

  • Setting up the BIG-IP system
  • Getting started with iRules
  • Leveraging DevCentral resources for iRule development
  • Exploring iRule elements, including events, functions, commands, variables, and operators
  • Using control structures for conditional branching and looping
  • Mastering whitespace, grouping, and special symbols
  • Measuring iRule efficiency using timing statistics
  • Logging from an iRule using syslog-ng and high-speed logging (HSL)
  • Optimizing iRules execution, including implementing efficiency best practices
  • Modularizing iRules for administrative efficiency, including using procedures
  • Securing web applications with iRules, including preventing common HTTP attacks, securing
  • HTTP headers and cookies, and implementing HTTP strict transport security (HSTS)
  • Working with strings, including using Tcl parsing commands and iRules parsing functions
  • Accessing and manipulating HTTP traffic, including applying selective HTTP compression
  • Working with iFiles and data groups
  • Using iRules with universal persistence and stream profiles
  • Gathering statistics using STATS and ISTATS
  • Incorporating advanced variables, including arrays, static variables, and the session table
