Edge computing is a modern technology that enables data to be securely collected and processed at the point of creation, allowing for new value to be created from the data. Edge computing uses distributed computing resources such as routers and gateways to process data close to the source, which reduces latency, improves efficiency and reduces the overall cost of data processing. Edge computing also enables data to be securely collected and processed in a decentralized manner, which improves data security and privacy. Additionally, edge computing enables the data to be processed in real-time, allowing for faster responses and more accurate results.

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.

Agent-based backup involves installing a software agent on the client system (in this case, a VM) that manages the backup process. The agent monitors the data on the client, processes it, and sends it to the backup device. This method provides granular control over the backup process and allows for more sophisticated features like incremental backups, compression, and encryption. Agent-based backups are commonly used in virtual environments because they provide detailed management and reporting capabilities for each VM, ensuring efficient and secure data protection.
