The article highlights the often-overlooked issue of data egress costs in cloud adoption. Research from IDC shows that these charges account for an average of 6% of organizations' cloud storage costs, and can be unpredictable, making it challenging to forecast and model them. Data egress fees are charged whenever data is moved out of a cloud storage location, and can add up quickly as an organization's cloud footprint grows. This can lead to vendor lock-in, limit the ability to fully benefit from the cloud, and raise operating expenses for hybrid and multi-cloud architectures. To reduce egress fees, companies can adopt demand management, architect for lower costs by prioritizing reduced inter-regional data transfers, use of data deduplication and compression, and redesigning data-intensive apps, choose the right services, bring data on-premises, and consider solutions that eliminate egress costs, such as CAST AI.
