Asynchronous remote replication is used when data centers are separated by large distances. This method does not impact application response time as much as synchronous replication because the write operations are completed on the source storage systembefore being sent to the remote site. This helps in minimizing the performance impact over long distances like 1600 km.

HDFS (Hadoop Distributed File System) is a file system that provides a streaming interface using the MapReduce framework. HDFS is designed to store large volumes of data across many machines and provides high-throughput access to this data. The MapReduce framework allows for processing and generating large datasets with a distributed algorithm on a cluster. HDFS's architecture is optimized for handling large files and supports operations such as writing data once and reading many times, making it ideal for big data analytics and processing tasks.
