Network - Run Semiconductor Design Workflows on AWS


AWS employs a number of technologies that allow you to isolate components from each other and control access to the network, including Amazon VPC and security groups.

Amazon VPC

Amazon Virtual Private Cloud (Amazon VPC) is a service that lets you launch AWS resources in a logically isolated virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways. You can use both IPv4 and IPv6 for most resources in your virtual private cloud, helping to ensure secure and easy access to resources and applications.

You can easily customize the network configuration for your Amazon VPC. For example, you can create a public-facing subnet for your FTP and Bastion servers that has access to the internet. Then, you can place your design and engineering systems in a private subnet with no internet access. You can leverage multiple layers of security, including security groups and network access control lists, to help control access to EC2 instances in each subnet.

Additionally, you can create a hardware virtual private network (VPN) connection between your corporate data center and your VPC and leverage the AWS Cloud as an extension of your organization’s data center.

Security groups

Amazon VPC provides advanced security features such as security groups and network access control lists to enable inbound and outbound filtering at the instance level and subnet level, respectively. A security group acts as a virtual firewall for your instance to control inbound and outbound traffic. When you launch an instance in a VPC, you can assign the instance to up to five security groups.

Network access control lists (ACLs) control inbound and outbound traffic for your subnets. In most cases, security groups can meet your needs. However, you can also use network ACLs if you want an additional layer of security for your VPC. For more information, see Security in Amazon Virtual Private Cloud in the Amazon Virtual Private Cloud User Guide.

You can create a flow log on your Amazon VPC or subnet to capture the traffic that flows to and from the network interfaces in your VPC or subnet. You can also create a flow log on an individual network interface. Flow logs are published to Amazon CloudWatch Logs. For more details, see VPC Flow Logs.
