VPN Connect provides a site-to-site IPSec VPN between your on-premises network and your virtual cloud network (VCN). The IPSec protocol suite encrypts IP traffic before the packets are transferred from the source to the destination and decrypts the traffic when it arrives.

On general, IPSec can be configured in the following modes:

Transport mode: IPSec encrypts and authenticates only the actual payload of the packet, and the header information stays intact.

Tunnel mode (supported by Oracle): IPSec encrypts and authenticates the entire packet. After encryption, the packet is then encapsulated to form a new IP packet that has different header information.

Oracle Cloud Infrastructure supports only the tunnel mode for IPSec VPNs.

Each Oracle IPSec VPN consists of multiple redundant IPSec tunnels. For a given tunnel, you can use either Border Gateway Protocol (BGP) dynamic routing or static routing to route that tunnel's traffic. More details about routing follow.

IPSec VPN site-to-site tunnels offer the following advantages:

Public internet lines are used to transmit data, so dedicated, expensive lease lines from one site to another aren't necessary.

The internal IP addresses of the participating networks and nodes are hidden from external users.

The entire communication between the source and destination sites is encrypted, significantly lowering the chances of information theft.

One or more of the backend servers reports as unhealthy.

A backend server might be unhealthy or the health check might be misconfigured.

You can filter results by request actions to zero in on only the events with operations that interest you. For example, say that you only want to know about instances that were deleted during a specific time frame. Select a delete request action filter to see only the events with delete operations

You can scale up/down your Autonomous Database to scale both in terms of compute and storage only when needed, allows people to pay per use.

Oracle allows you to scale compute and storage independently, no need to do it together. these scaling activities fully online (no downtime required)

in Details page Autonomous Database click Scale Up/Down. Click on arrow to select a value for CPU Core Count or Storage (TB).

Or Select auto scaling to allow the system to automatically use up to three times more CPU and IO resources to meet workload demand, compared to the database operating with auto scaling disabled.
