Which component is essential for creating a secure connection from on-premises data centers to OCI?

FastConnect is essential for creating a secure connection from on-premises data centers to Oracle Cloud Infrastructure (OCI). It provides a dedicated, private connection that bypasses the public internet, enhancing security and reliability for data transfer between on-premises environments and OCI resources. FastConnect offers a consistent performance, low latency, and higher bandwidth options suitable for enterprise-grade applications, making it the preferred choice for organizations that require a secure network connection.

Public IP addresses allow devices to be reachable over the internet but do not inherently provide a secure connection. Similarly, although a Service Gateway allows private connectivity within OCI, it does not extend security or connectivity features to on-premises data centers. An Internet Gateway also supports public internet access for OCI resources but lacks the private, secure, and reliable connection that FastConnect offers for hybrid cloud architectures.
