Methods and apparatus for providing a secure overlay network between clouds
A process capable of automatically establishing a secure overlay network (“SON”) across different clouds is disclosed. The process, in one aspect, receives a first request from a first node in a first cloud for establishing a SON. After receiving a second request for connecting to the SON from a second node in a second cloud, a first connection is established connecting between the first node and the second node utilizing a network security protocol such as Internet Protocol Security (“IPSec”). After receiving a third request for connecting to the SON from a third node in a third cloud, a second connection is used to connect between the first node and the third node. A third connection is used to connect between the second node and the third node. Each subsequent request for connecting to the SON from a new node results in new connections between the new node and each existing node in the SON forming a full-mesh.

9. The network of claim 1 , further comprising a dashboard managed by the orchestrator and configured to provide an option of creating a secure overlay network (“SON”) to a user via the communication network.
10. A method for generating network connections between cloud computing managed by an orchestrator, comprising:
presenting a dashboard including an option of creating a secure overlay network (“SON”) to a user by the orchestrator via a communication network, wherein the orchestrator comprises a computer processor;
receiving over the communication network a first selection requesting a first SON for a point-to-point connection from a first interior input and output (“I/O”) port of a first virtual server inside a first cloud;
receiving over the communication network a second selection requesting the first SON and a second SON from a second interior I/O port of a second virtual server inside a second cloud;
establishing a first point-to-point logically direct connection laid over an existing network between the first interior I/O port of the first virtual server and the second interior I/O port of the second virtual server in accordance with the first SON utilizing a network security protocol, wherein the existing network connects a first edge I/O port of the first cloud to a second edge I/O port of the second cloud;
receiving a third selection requesting the second SON from a third virtual server in a third cloud and establishing a second point-to-point connection between the second virtual server in the second cloud and the third virtual server in the third cloud in accordance with the second SON utilizing Internet Protocol Security (“IPsec”); and
