Resource and Cost Planning

The following table describes the resource planning in this best practice.

**Table 1** Resource and cost planning
Resource	Description
Elastic Cloud Server (ECS)	A file system and the ECSs must belong to the same project so that data can be shared between the ECSs through the file system.
Virtual Private Cloud (VPC)	VPC provisions an isolated virtual network environment defined and managed by yourself, improving the security of cloud resources and simplifying network deployment. A server cannot access file systems in a different VPC. Before using SFS, assign the file system and the servers to the same VPC.
File system	A file system provides users with shared file storage through NFS and CIFS. It is used for accessing network files remotely. After a user creates a file system on the console, the file system can be mounted to multiple servers and is accessible through the standard POSIX.
