Yes, Hamza, good question. On the first part of your question, I think in kind of, why are we seeing increased traction in those large-scale enterprises, it really is kind of both a push pull. What I mean is, I think we continue to put a lot of engineering and development effort into broadening and deepening the capabilities of the SaaS offerings to effectively make a kind of use case equivalent to the on-prem offering. So I think when I tie in enterprise class customer looks for the things they expect to see in a product of this nature, they see those things now, in our IdentityNow product. And so I think that's probably kind of open their mind to it. And then, the pull, if you will, that's the push from us, in my metaphor here to pull from them, it's just -- I think it just increased openness over time to accept this particular kind of technology from the cloud. I think, one things we always remind people of is, we're a very market driven company, when we talked to the market 15 years ago, when get this company started. Again, 10 to 12 years ago, I mean, sorry, eight to 10 years ago, it was just very clear that those high-end customers were not really interested in getting this product delivered as a SaaS offerings, that has shifted. I think their preference has shifted to a kind of a SaaS first expectation, their confidence in the kind of bulletproof nature of the security environments of the cloud providers like Amazon and Azure and Google is just very high. And so I think they trust and believe this is in fact, a very secure way to manage it and they get that SaaS is just a really, really smart way to do this to continue to allow them and as to extend the product quickly and easily over time. So I think it's a push pull there. To your second point, on the legacy environment. I used to play some baseball, I guess I'll give you about a second or third inning on this deal. And I think we're certainly in the first third of the game, how's that? I don't think we're into the middle innings yet, I think we're in the first third of the game in terms of the amount of legacy particularly legacy implementations in these larger enterprises that is still yet to be turned over. And so we're pretty bullish on the number of places, we think we can still take the solution in the Fortune Global 5000 around the world, I think there's a lot of installed identity products out there still from the legacy players.
