Another good news from Amazon Web Services. Now the Virtual Private Cloud service supports m1.micro size instances. What does this mean for us? Those who use micro discussions can now merge them into private networks that are isolated from the outside world.
It is also now possible to take advantage of the charms of VPC for free - Free Tier. This news is so hot that the Free Tier list has not yet been updated using VPC. New accounts can use m1.micro instances in a VPC of 750 hours per month for a year. ')
I recall that Amazon Virtual Private Cloud is one of the AWS services that allows you to create private networks and easily configure network interfaces for hosts. Those instances that do not have public addresses are behind NAT and access to them is provided via VPN. The basic idea behind VPC is an even more secure network, to which there is no external access. This is the fundamental difference between VPC and EC2 Security Groups.
