While walking past a bookshelf in my office, I caught a glimpse of something
shiny. What was that?
Well, it was this. The “iRuler v1.0” disk. Not many folks know that the
iRule Editor was humorously called the “iRuler” in it’s early days by
creator Joe Pruitt. In classic F5 (and Pruitt) form, he showed up one day and
said, “hey guys – what do you think of this?”.
Suffice it to say that after many enhancements and literally tens of
thousands of downloads, it’s a big part of the F5 DevCentral journey and
has certainly had a profound impact on the thousands of users writing and
deploying iRules around the world.
Anyone want the master? It might be a nice collectible for that iRule addict
in the community that has the have EVERYTHING iRule! Tell me why you should
have it (in the comments below) and if your story is good enough, I might
send it to you!
To provide the best application performance, reliability, scalability, and
security for J2EE applications, many large organizations utilize network
load-balancing appliances and application switches. However, coordinating the
deployment of applications between application developers and network
managers can be a slow, painstaking process for companies choosing the many
advantages of the network-based, load-balancing switches.
By developing an application to manage the time-consuming coordination
between these two teams, developers can self-serve their needs more quickly,
Service Oriented Architecture (SOA) is the most significant transformation in
IT application architecture in the past several years - representing open
standards and a more loosely coupled approach to designing, developing, and
While attention is given to the application side of SOA, an often-overlooked
ingredient needed to ensure its successful delivery is the underlying network
infrastructure. As important as the application tier is, a new
service-oriented network (SON) approach is crucial to providing a nimble
infrastructure that can accommodate SOA's ... (more)
You know what? You never know what you might find in the DevCentral Forums.
Some pretty cool stuff happens in the Solutions Forums - a place to focus on
doing interesting things with F5 gear from an application perspective (i.e.
Microsoft app, Oracle App, etc.).
Here's an interesting one I found recently: load balancing resources
protected by MS-AD-Kerberos. Not always two technologies you expect to see
together... However, thanks to user "ravi.rajan", there's the solution. The
trick is that you don't add the BIG-IP to the AD (you can't). Instead, you
create a Microsoft Service ... (more)
Election Day 2008 represented many “firsts”. As more people document
President Obama’s campaign team and their creative use of social media
(Twitter, etc.), one aspect few have explored is the web infrastructure used
to support the flurry of online activity. For MSNBC.com, Election Day 2008
represented the biggest day of traffic in it’s 12-year history with over 20
million unique viewers and 250 million page views. Wow.
When it comes to IT, it’s always fun to throw around big numbers. Well,
these are indeed BIG numbers.
Here is a particularly interesting aspect that really speaks... (more)
