A Brownfield Application is a type of application that allows you to import and manage existing VMs that were not deployed by Calm. You can use a Brownfield Application to perform actions such as start, stop, restart, delete, or execute scripts on the imported VMs. You can also add services, credentials, variables, and policies to the Brownfield Application blueprint. To create a Brownfield Application, you need to select a multi-VM blueprint and then choose the VMs that you want to include in the application from the drop down list. You can also filter the VMs by name, cluster, or power state.
A Greenfield Application is a type of application that allows you to deploy new VMs from scratch using Calm. You can use a Greenfield Application to provision and configure VMs on different cloud platforms, such as Nutanix AHV, VMware ESXi, AWS, Azure, or GCP. You can also add services, credentials, variables, and policies to the Greenfield Application blueprint. To create a Greenfield Application, you need to select a single-VM or a multi-VM blueprint and then specify the VM properties, such as name, image, flavor, network, storage, etc.
