Cloud HDFS (CHDFS) provides the standard Hadoop Distributed File System (HDFS) access protocol, so you can use a distributed file system with high availability, high reliability, multidimensional security, and hierarchical namespaces without modifying your existing code. You can create and mount a CHDFS instance in the cloud in just a few minutes for big data storage. As your business needs change, you can easily expand or reduce the storage capacity in real time. CHDFS offers an unlimited storage space to satisfy your business needs for big data storage and analysis. In addition, it enables you to separate compute and storage, maximize the flexibility of computing resources, and implement permanent data storage, which help reduce the costs of your big data analysis resources.
