The Amazon Web Service (AWS) is a public cloud service
that enables you to run your applications on a shared infrastructure
managed by Amazon. These applications can be deployed on scalable
computing capacity or EC2 instances in different AWS regions and
accessed by users over the internet.
For networking consistency and ease of management of EC2 instances,
Amazon offers the Virtual Private Cloud (VPC). A VPC is apportioned
from the AWS public cloud, and is assigned a CIDR block from the
private network space (RFC 1918). Within a VPC, you can carve public/private
subnets for your needs and deploy the applications on EC2 instances
within those subnets. To then enable access to the applications
within the VPC, you can deploy the VM-Series firewall on an EC2
instance. The VM-Series firewall can then be configured to secure
traffic to and from the EC2 instances within the VPC.
The VM-Series firewall is available in both the public AWS cloud
and on AWS GovCloud. The VM-Series firewall in public AWS and AWS
GovCloudsupports the Bring Your Own License (BYOL) model and the
hourly Pay-As-You-Go (PAYG), the usage-based licensing model that
you can avail from the AWS Marketplace. For licensing details, see VM-Series
Firewall Licenses for Public Clouds.
