comment Combined arrival rate
Considering the same proof you provided, the case of $\lambda_a = \lambda_b$ still valid, isn't it? (sorry for the naive confirmation)

Queueing theory will give you a metric in steady-state only. As conditions of life and resources are time-varying, as pointed by @MichaelHardy, such model is not useful. A differential (difference) equation will more suitable type of model. (just for fun: see Logistic Map for a reference)

Yes, I got it. For instance, I also expand this question here. Could you comment there also? (thank you very much)

comment Combined arrival rate
Supposing $(0,T]$ is the time in which the samples happen, why let the Poisson random variables' parameters be $\lambda_a T$ and $\lambda_b T$ instead of $\lambda_a$ and $\lambda_b$?

@DilipSarwate, consider they are independent processes. Could you give an example of why the answer, then, is the sum of the rates? (thank you)

@JimmyK4542 yes, but I don't think it impact in the response. VMs (y axis) refers to the amount of virtual machine that host a service after a step in the workload. E.g in a cloud computing environment.

comment How to factorize $2x^2+5x+3$?
Very informative and algebric answer. If it'd be possible, I'd maked it as an accepted answer together with the `amWhy' answer. Thank you.

comment How to factorize $2x^2+5x+3$?
I'm sorry, I could not understand how you do that $f=2x^2+5x+3 \iff 2f=(2x)^2+5(2x)+6$; shouldn't it be $(2)(2x)^2$? @bill-dubuque
