HTTP redirect to pools

 

I want to be able to route ALL http traffic between different pools

 

 

For Example:

 

 

3 web servers in Pool A

 

5 web servers in Pool B

 

 

All 8 web servers in Pool X

 

 

So normal day to day operations all HTTP traffic routes to Pool X

 

 

But when we are doing code releases All HTTP traffic routes to Pool B, while code is being updated on servers in Pool A once completed, we route all HTTP traffic to Pool A and update code on Pool B, once all code has been updated for both Pools we revert back to Pool X

 

 

That is our process, what I'm after might be as simple as route All HTTP traffic to Pool *, then we manually change the rule once each step above is completed

 

 

thanks in advance

    Hi,

     

     

    If you don't do this very often, you could use a single pool and use priority group activation. You could raise the priority on the servers that you want to send all of the traffic to, upgrade the remaining servers and then reverse the process. When all servers have been upgraded you could reset the priority to be even. You can check the LTM config guide for your version for details on load balancing pools and priority groups within the pools.

     

     

    There are other more complicated options, but they'll probably add unnecessary overhead in all cases to handle a fairly limited case.
