Designing AWS Networking Services: NAT Instances and NAT Gateways
NAT instances and NAT gateways. Which one to use when. So this is kind of the similar conversation with Elastic Load Balancer versus a traditional load balancer like an F5 or a Citrix NetScaler or the do-it-yourself type of load balancer. You’ll find that a lot of the pros and cons are very similar. Again, a NAT gateway offers you the same thing as a NAT instance except it’s an as-a-service, whereby AWS is responsible for the high availability, for the scalability, for the software updates, functionality, etc. ,
All you have to do is basically configure it through the platform, whereas a NAT instance you’re, again, deploying it. You’re responsible for high availability. You’re responsible for scalability. You’re responsible for making sure that that instance can support the traffic that you’re running through it. Really cool stuff! Welcome back to our web site.
