Which of the following is a best practice for Big Data migration?

The best practice for Big Data migration is to utilize object storage. This approach is particularly well-suited for handling the diverse and extensive datasets typically involved in big data processes. Object storage systems are designed to manage large amounts of unstructured data, providing scalability and flexibility.

When migrating data, it's essential to have a storage solution that can accommodate the size and complexity of big data. Object storage allows for the efficient storage of data objects, which can include text, images, videos, and other forms of unstructured data. This system enables easier access and management, as well as improved performance for analytics and processing tasks over traditional file systems.

In addition, object storage often provides features such as automatic data replication, which enhances data durability, and built-in metadata capabilities, which can simplify the organization and retrieval of data. These attributes make it an ideal choice for bulk data migration during big data projects, ensuring that data can be efficiently stored, retrieved, and processed once migrated.
