•Programmability in the network enables you to act and react, on demand, to operational and business events. •Automation of application deployment, device deployment, application reconfiguration, and support initiation can pay dividends immediately. •The ability to customise application services results in faster time to market, more innovation, and increased application ROI.

BUSINESS
requires applications to become more agile
SECURITY
must be everywhere, from the network to the applications and the management
OPERATIONS
need visibility of the resources at different levels (app, data center, network)
NETWORK
is changing faster to support new applications and customers
APPLICATIONS
are dynamic and customer aware (profiling)

“High performing organisations deploy code 30 times more often and 8000 times faster than their peers, deploying multiple times a day, versus an average of once a month. [...] The net results are lower business risk and more operational agility.”

Work with vendors
Leverage your vendor’s APIs
Iterate
You're not going get it right the first time
Build frameworks
Define reusable components
Programming skills
Invest in skills
Where Do You Start Investing to See These Advantages?

11. © F5 Networks, Inc.
11
1) Invest in Programming Skills
How to invest in building skills
Make automation part of employee goals
Carve out space and time to write code
Start small and move to larger goals
Investing in programming skills begins with training and perfects through using the skills on a regular basis
Examples of programming skills
Use languages that your vendors use and support
Explore and understand samples that exist within language eco-system
Write programs and have them execute against the APIs

12. © F5 Networks, Inc.
12
2) Leverage Your Vendor’s APIs
How do you leverage them?
Look for examples of how the APIs are created
Pick the language that works best for you: REST, SOAP, Perl, Python, PS
Interact with the larger community using the same APIs
Vendor APIs are there to help you get the job done, if the APIs are not good enough, call them out on that fact and make them better
What is a vendor API?
Documented, open, and supported interface into software or hardware
System that supports one or more languages
System with plenty of examples, code samples, and a community

3) Build Internal Frameworks
How are they built?
Take common groups of tasks and program a block of work out of them
Promote and share the information
Use tools such as github, wikis, or even shared documents to socialise
Frameworks make unities of work reusable, shareable, and create a common set of tools that the entire organisation can benefit from
What is a framework?
Structures that implement units of work
Frameworks encourage collaboration
Frameworks are common tools, written in-house that an be reused

4) Iterate Towards Perfection
Examples of iteration
Write a small piece of code and then build on it
Write, test, deploy, edit, test, deploy
Functional code solves a business problem
Don’t try to solve all of the problems on the first go-around, your organisation will realise better ways to solve problems and the solutions will improve with time
The myth of perfection
Myth: You are going to get the program right the first time
Myth: You will understand the problem you’re solving
Myth: You need “programmers” to write code

Consistency
Free up your team to work on more important tasks
Deploy the architecture that you are interested in
Ensure same setup and parameters every time
PROBLEMS:
•New applications are coming on-line, old ones are changing
•Dynamic infrastructure requiring frequent setup of new ADC units

Provisioning Application Delivery Controllers
The solutions
SOAP or REST APIs work over the network to provision
Programmable deployments mean every ADC is consistent
Let your experts spell out the details in a program
Testing has shown a reduction from 65 to 6.5 minutesin setup time for ADC with automation in place
The challenges
Cloud: New licensing models mean more ADCs in more places
Inconsistencies: Increasing problems and troubleshooting
Expertise: Not enough time to train all team members

•Completely open architecture
•Common API across all ADC modules
•REST API for device to device communication
•REST API for management to platform communication
•Value added services

Provisioning Applications
The solutions
Pre-built app services templates solve the settings for you
Using an app template means you get the same settings every time
Building your own templates allows you to bundle ADC knowledge
Several hundred objects are required for a complete Microsoft Lyncdeployment, app templates reduce these to a number of questions
The challenges
Complexity: What are the best settings for enterprise apps?
Inconsistencies: ADCs are setup with different settings
In-house apps: Taking a long time to deploy
