In cloud computing, Data Transfer Costs refer to the costs associated with transferring data between different services, regions, or accounts within a cloud environment. These costs can vary depending on the cloud provider, the amount of data being transferred, and the locations involved.

Data Transfer Costs are typically based on the amount of data transferred (measured in gigabytes or terabytes), with costs increasing as more data is transferred. Some cloud providers may offer free data transfers in certain situations, such as inbound data transfers or transfers within the same region.

For example, a company, TechCorp, might incur data transfer costs when moving data from its on-premises data center to the cloud, or when transferring data between different cloud regions or services.
