- There are times when we need to ensure that we have enough resources available, as well as making sure that they are available. How do we do that? Stay tuned to find out. - [Narrator] You're watching "ITProTV." (soft electronic music) - Hello ladies and gentlemen. Thank you for tuning in to more of the CompTIA Cloud .
