Before you allocate resources, you need to identify the deployment type based on your requirements for the volume of processing and the level of concurrency. Based on the deployment type, you can allocate resources for disk space, cores, and RAM. You can also choose to tune services when you run the installer.

You can create a domain with one node and run the services on the same node or you can create multiple nodes in the domain. When you plan the application services for the domain, consider system requirements based on the services that you run on a node.

The following table lists the minimum system requirements for a node based on some common configuration scenarios:

Services	Processor	Memory	Disk Space
One node runs the following services: CDI-PC Integration Service CDI-PC Repository Service Web Services Hub	2 CPUs with multiple cores	8 GB	15 GB
One node runs the following services: CDI-PC Integration Service CDI-PC Repository Service	1 CPU with multiple cores	4 GB	10 GB

The sizing requirements account for the following factors:

Disk space required to extract the installer
Temporary disk space to run the installer
Disk space required to install the services and components
Disk space required for log directories
Requirements to run the application services

The sizing numbers don't account for operational data processing and object caching requirements for native mode of execution.
