Which of the following is a security consideration when moving to a cloud environment?

Vendor lock-in is a significant security consideration when moving to a cloud environment because it relates to the long-term dependency on a particular cloud service provider. When organizations utilize specific cloud services, they often integrate their systems and processes with the provider’s tools and frameworks. This can make it very challenging to migrate to another provider or move applications back on-premises if needed, thereby locking the organization into that vendor's ecosystem.

The implications of vendor lock-in are not just logistical; they can also pose security risks. For instance, if the vendor experiences a data breach or if its security practices do not meet the organization's compliance requirements, the organization might find itself unable to switch providers swiftly or efficiently. Additionally, assessing the security measures and controls of the vendor becomes crucial because the organization’s data security largely relies on the vendor's capabilities.

While aspects like reducing costs, improving uptime, and scaling resources are important operational benefits of cloud adoption, they do not specifically relate to security considerations or potential vulnerabilities indicated by vendor lock-in.
