F5 BIG-IP Sizing Requirement

Hi Expert There is ongoing  requirement for putting all internet facing applications behind web application firewall, and WAF TPS consume F5 CPU and memory and other parameters as well. Fear is that...
application delivery
F5 boxes sizing
ssl

    for raw estimation:
    (your_targeted_tps at 5th year / 80% ) x 4  = required F5 datasheet tps

    5th year: because usually company's asset depreciation is calculated for 5 years.
    80% ==> so you have 20% buffer
    x 4 ==> because usually f5 datasheet spec is cut by 75% for heavy processing (WAF, complex irules, etc.)

Azim_IIPL Sadly this is not a straightforward answer without knowing the requirement. You really need to know from a business standpoint how many features the plan to use on the F5 and then purchase the appropriate devices if they are physical F5s or ensure you have a hypervisor that can support a large enough F5 VE.

PauliusYuP, I think you are not goted my point, Already we have 14 Boxes installed in our environment,

the thing is that we are going to check and perform Current ongoing throughput  and total threshold.

 

The client's requirement is to determine the maximum load capacity for these boxes if they wish to load them in the future. In other words, they want to know how much weight the boxes can tolerate.
