Sample DXP Cloud Deployment Model Key highlights of the cloud deployment model of the DXP application as depicted in Figure 8-1 are as follows: • The environments will be hosted in the specific region of Amazon Web Services (AWS). • There are three environments Prod, SIT, and Dev; these will be hosted in two separate VPCs, designated as Prod and Non-Prod VPCs. • A separate management VPC will serve both the Prod and Non- Prod VPCs. In Figure 8-1 we have “Production VPC” for running the production instance of DXP and “Non-Production VPC” for running the Dev and SIT instances of DXP. 227
