If you want to use AWS Application Migration Service or Cloud Migration Factory on AWS for a rehost migration to the Amazon Web Services (AWS) Cloud, one of the prerequisites is that you must keep TCP ports 443 and 1500 open. Typically, opening these firewall ports requires approval from your information security (InfoSec) team.
This pattern outlines the process to obtain a firewall request approval from an InfoSec team during a rehost migration to the AWS Cloud. You can use this process to avoid rejections of your firewall request by the InfoSec team, which can become expensive and time consuming. The firewall request process has two review and approval steps between AWS migration consultants and leads who work with your InfoSec and application teams to open the firewall ports.
This pattern assumes that you are planning a rehost migration with AWS consultants or migration specialists from your organization. You can use this pattern if your organization doesn’t have a firewall approval process or firewall request blanket approval form. For more information about this, see the Limitations section of this pattern. For more information on network requirements for Application Migration Service, see Network requirements in the Application Migration Service documentation.
