 # Possible Use Cases
 
-* Machine learning
+## Machine learning
   * Problem
     * Training jobs need to repeatedly visit a large set of files. 
     * The randomized access pattern is hard for caching.

     * Users can explicitly ask SeaweedFS Cloud Cache to cache one whole folder.
     * Increase training speed and reduce API cost and network cost.
     * Users can access data with FUSE mounted folders.
-* Data Hoarding
+## Data Hoarding
   * Problem
     * With cloud capacity and storage tiering, saving data files there may be a good idea. 
     * Recently uploaded files very likely need to be accessed again.
   * With SeaweedFS Cloud Cache
     * Users can explicitly ask SeaweedFS Cloud Cache to uncache by file age.
     * Users can also choose to never uncache, basically treating cloud copy as a backup.
-* Big Data
+## Big Data
   * Problem
     * Run MapReduce, Spark, and Flink jobs on cloud data is slow due to metadata operations.
     * Repeated data access increases unnecessary cost.

     * Avoiding slow cloud storage metadata access.
     * Access data only once.
     * Write back data to work with cloud ecosystems.
-* Cloud Storage Vendor Agnostic
+## Cloud Storage Vendor Agnostic
   * Problem
     * Different datasets may need to be on different vendors, based on access pattern, latency, cost, etc.
   * With SeaweedFS Cloud Cache
     * Transparently switch to from one vendor to another.
-* Switch S3 Compatible Storage Vendors
+## Switch S3 Compatible Storage Vendors
   * Problem
     * Other S3 compatible vendors are known to have lesser flexibility, scalability and performance as SeaweedFS.
   * With SeaweedFS Cloud Cache
     * Compare SeaweedFS with the vendor over a long period of time.
     * Transparently switch away if SeaweedFS works better.
-* Move Off Cloud
+## Move Off Cloud
   * Problem
     * Cloud storage is costly!
   * With SeaweedFS Cloud Cache
     * Help to transition between on-cloud to off-cloud.
     * When you are happy with it, just stop the write back process (and cancel the monthly payment to the cloud vendor!).
-* Support multiple access methods.
+## Support multiple access methods.
   * Problem
     * You may need to access cloud data by HDFS, or HTTP, or S3 API, or WebDav, or FUSE Mount.
