Why use a VPC on AWS?
Hi all,
Just wondering on this one - have been looking at various articles/guides on running WHM and a couple of DNSONLY EC2s on Amazon AWS. All of them include using a VPC but none of them say why.
Could any one enlighten me please?

Hello, VPC makes the network configuration a straightforward process, which is useful when installing and using cPanel. Amazon documents VPC at: What is Amazon VPC? - Amazon Virtual Private Cloud This section in-particular lists several reasons why it's beneficial: By launching your instances into a VPC instead of EC2-Classic, you gain the ability to: [LIST] - Assign static private IP addresses to your instances that persist across starts and stops
- Assign multiple IP addresses to your instances
- Define network interfaces, and attach one or more network interfaces to your instances
- Change security group membership for your instances while they're running
- Control the outbound traffic from your instances (egress filtering) in addition to controlling the inbound traffic to them (ingress filtering)
- Add an additional layer of access control to your instances in the form of network access control lists (ACL)
- Run your instances on single-tenant hardware
