See Managing Backend Sets.* Backend servers for your backend set.
See Managing Backend Servers.* One or more listeners . See Managing Load Balancer Listeners.* Load balancer subnet security rules to allow the intended traffic. To learn more about these rules, see Security Rules.* Optionally, you can associate your listeners with SSL server certificate bundles to manage how your system handles SSL traffic. See Managing SSL Certificates.

Load Balancing automatically checks the health of the instances for your load balancer. If it detects an unhealthy instance, it stops sending traffic to the instance and reroutes traffic to healthy instances. In this step, you provide the information required to check the health of servers in the backend set and ensure that they can receive data traffic.

Explanation
Use the File Storage service when your application orworkload includes big data and analytics, media processing, or content management, and you require Portable Operating System Interface (POSIX)-compliant file system access semantics and concurrently accessible storage. The File Storage service is designedto meet the needs of applications and users that need an enterprise file system across a wide range 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 cloudfor backup and disaster recovery purposes.
MicroServices and Docker: Deliver stateful persistence for containers. Easily scale as your container-based environments grow.
