How to configure my simple website using JAVA and apply F5 Big-IP LTM to each server??

Hi Everyone,

I'm new on the F5 solution and i'm a little bit confuse on how can configure my simple website(created in Java) and apply my F5 Big-IP?? Do i need to configure inside the codes on my website??or i can configure it in the management console on F5 like including the website DNS/URL??

Regards,

The domain name must be configured at your DNS service provider.
Say your site should be www.my-awesome-site.com, then you need configure you DNS to point to the virtual IP you configured on the BIG-IP. Or in case there is a NAT device in front of the BIG-IP, you have to use the NATed IP.

If you need to redirect to some specific URL or Directory, you can do this with LTM Traffic Policies.

If you want your site to use SSL you have to configure a clientside SSL profile and you have to have a SSL cert + private key.
On the AskF5 youtube channel there are a couple of videos regarding SSL Certificates.

Hi Renato,

maybe this video from the AskF5 YouTube channel, a good source for getting started, can help you:
Quick deployment A one armed load balancing configuration
It explains how to setup a BIG-IP and how to setup load balancing a single application. Don't worry, it's easy and no code changes to your app are required.

Hi Daniel,

Thanks for the reply :). What i don't understand sir is how did the F5 know what HTML/Web Page to display when you try to access the Virtual Server IP shown in the video??Like showing Serve1 & Server2 Page??

  Aha, you are asking, how the BIG-IP will know what is the webpage to display? Whether it is index.html or index.php or start.htm. Right?
  If your website is running on a webserver like nginx oder Apache, you will have a default document configured. When you access the location /, the webserver will know what page to show because you configured it.
  The BIG-IP will not change this behaviour of the webserver.

Hi ,

yes your right, I'm just confused because he only provided an IP for his pool member and not the URL/Domain name/Directory location of his html but still it automatically show the page.. What i plan on my lab is to create a simple website(live w/ free domain name and hostserver(infinityFree)) and integrate F5 big-ip on my web application to provide SSL Load Balancing using 3 web server on my VMWare. sorry for the noob question 😅
