Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file system that you can mount to any compute instance inside your VCN and outside the VCN, using either OCI FastConnect or an IPSec VPN.
The File Storage service supports the Network File System version 3.0 (NFSv3) protocol and the Network Lock Manager (NLM) protocol for file locking functionality.
The File Storage service is designed to meet a variety of of use cases, including the following:
- General Purpose File Storage: Access to an unlimited pool of file systems to manage growth of structured and unstructured data.
- Big Data and Analytics: Run analytic workloads and use shared file systems to store persistent data.
- Lift and Shift of Enterprise Applications: Migrate existing Oracle applications that need NFS storage, such as Oracle E-Business Suite and PeopleSoft.
- Databases and Transactional Applications: Run test and development workloads with Oracle, MySQL, or other databases.
- Backups, Business Continuity, and Disaster Recovery: Host a secondary copy of relevant file systems from on premises to the cloud for backup and disaster recovery purposes.
- MicroServices and Docker: Deliver stateful persistence for containers. Easily scale as your container-based environments grow.
Without the appropriate IAM permissions, you cannot export a file system through a mount target. Until a file system has been exported, it cannot be mounted by Compute instances.
If you have successfully exported a file system on a subnet, then you use Networking security lists to control traffic to and from the subnet and the mount target. Security lists act as a virtual firewall allowing hosts send and receive packets and mount the file system.
