I think, Walter, that's a fair question. But if you look at our core business of firewalls, we're doing really, really good in firewalls. Our teams are innovating. We had a DNS security as-a-service, as a subscription. We are working on some more interesting things. Hopefully, we shall be able to share more about them in upcoming quarters. But there is innovation going on for sure in our core business where our firewall capabilities and other capabilities around it are developing. That's where we have strength. We have hundreds of engineers, if not thousands, working on our core networking capability and firewall security capability. We also had bills capability around endpoint with Traps and Secdo, which as I mentioned, we are rated best in the number of unmissed attack vectors as far as MITRE's test was concerned. So clearly, we have that core capability. Cloud was an area where all of you are asking the question, how will Palo Alto networks make the transition to cloud? Do we have the core capability. I think it's fair to say we have used the RedLock contingent and the evident team to create the core for the cloud, but at the same time, we didn't want to wait. With Twistlock having ordered 250 customers who are using them for container security, we didn't want to wait. We also, at the same time, launching a vulnerability scanning capability in RedLock, which is the early steps towards containers. But our customers want the entire thing. They want the full capability for container security. They want best-of-breed. So it became incumbent and imperative that we create this combination of RedLock and Twistlock. And honestly, if you go back and think, the price we paid for RedLock versus the fact that it crossed $100 million run rate this quarter means we must have done a good deal because in two quarters, we're able to take that product and deploy it to our -- across our entire sales force. Yes, we have cloud capability. We have it in our sales force. We have it in our RedLock team. We have it in our Twistlock team. We should be able to put the RedLock, and Twistlock, and PureSec capability together, and use our core team and our cloud sales teams to be able to go and create more revenue in this product. Because I think right now, there is a TAM of over $2 billion in cloud security, which is unserved. There are not enough products. There are not enough salespeople going out and demonstrating the product of to those customers. So right now, it's really a question of sort of a land grab, going out there and demonstrating the product to the customer, being able to deploy in their enterprise, and being able to have people who understand these products well enough to be able to solve them.
