What is Application Acceleration Manager?
• Web Accelerator Manager
• WAN Optimization Manager
• Web Accelerator will optimize your web applications and
decreases page load time anywhere from 10 to 90%
• WAN Optimization Manager will optimize network traffic
and reduce latency
What happens if I already own WA or WOM?
• You will be licensed as AAM with 11.4
• Since WA and WOM are AAM, you get both features
6
What is Centralized Policy Matching?
• Policy matching framework enables creation of flexible L7
policies:
• Centralized policy matching across BIG-IP modules
• Protocol-neutral matching for HTTP and other L7/L4
protocols
• Replaces HTTP class in v11.4

VXLAN Functionality
What does this really mean?
• Simplify the Expansion of Virtual Networks
• Apply Services across
Heterogeneous Networks
for Optimized Performance
• Improve Application
Mobility and Business
Continuity
12
Configuring VXLAN from the CLI
create net vlan vxlancontrol { interfaces add { 1.1} mtu 1550 }
create net self myvtep { address 10.1.1.1/32 vlan vxlancontrol }
create net tunnels tunnel vxlan5000 { local-address 10.1.1.1 remoteaddress 239.0.0.1 profile vxlan key 5000 }
create net vlan legacy5000 { interfaces add { 1.2 } }
create net vlan-group vxlan5000-bridge { members add { legacy5000
vxlan5000 } }
create net self vxlan5000-defroute { address 11.1.1.254/32 vlan
vxlan5000-bridge }
13
NVGRE Functionality
• Gateway between multiple Microsoft Hyper-V enabled
virtual networks
• NVGRE Gateway plugin available for Microsoft’s
System Center Virtual Machine Manager on DevCentral

What is Programmable Infrastructure?
Programmable infrastructure improves IT agility to
deliver your applications faster and with higher
predictability.
Extensibility
Management Plane
Data Plane
Control Plane
15
Programmable Infrastructure
Unleashing TMOS Programmability
iRules
Intercept, inspect,
transform, direct and
make decisions based
on inbound and
outbound application
traffic.
iApps
Define and tie all
related application
availability, security
and optimization
services to the
application. Deploy
these services with
optimum,
application-specific
configurations in
only a few minutes.
iControl
Realize new levels of
automation and
configuration
management with F5’s
web services–enabled
open.
iCall
Automate tasks to
improve
operations by
monitoring for
events and
executing scripts
to resolve issues
quickly and
predictable.
What’s New
iRule Procedures
Build a library of
functionality that can be
re-used, controlled and
managed in a consistent
way
Generic iApps
Leverage application
service objects to
provide a logical
container and context
to your application
without the need for
deployment
templates.
iControl REST
REST provides a
modern lightweight API
standard for
integration preferred
Control Plane
Automation
Automate BIG-IP
to dynamically
respond to events
and perform BIGIP configuration
actions.
16
iCall Examples
Local Traffic Manager
Triggered
–
Run TCP Dump on an event
–
Detect server errors and mark server down in a
pool on excessive errors
–
On Failover, generate qkview and/or ucs
–
GTM Monitor weight change - Set LTM wildcard
virtual server "VS Score" value based on the
number of available pool members of tertiarilyrelated (that is, non-default to the VIP) pool.
–
–
Re-prioritization of SharePoint nodes based on
the SharePoint -reported health value that is
delivered in an HTTP response.
Automatic qkview creation upon core dump or
unknown restart - Customers are frequently
asked to generate qkviews for support to
troubleshoot issues. To improve the chance of
repro, it would be good to have an event that
detects core dumps/ restarts and automatically
creates a qkview.
Periodic
•
Generate Config Backup
•
Pool Synchronization from DNS - use an
iApp to accept a list of host names that
will be used to populate a pool via DNS.
Detect when the results of the resolution
change and repopulate the pool to stay
synchronized.
•
Pool update on DHCP response - create
a script that takes DHCP responses and
adds the IPs to a pool.
•
Re-prioritization of SharePoint nodes
based on the SharePoint -reported health
value that is delivered in an HTTP
response.
•
Datagroup Sync with external source
Perpetual
•
Achieve application delivery optimization
and enhanced productivity without the
need to rewrite applications
17
JavaScript and CSS Minification
What does this really mean?
• Reduces overall file size
• Removes whitespace
• Removes comments

Before: 6,167 Bytes
After : 5,574 Bytes
