Multi-cloud edge system

1. A multi-cloud edge system, comprising:

a core cloud;

a multi-cluster-based first edge node system; and

a multi-cluster-based near edge node system,

wherein the multi-cluster-based first edge node system comprises:

multiple worker nodes; and

a master node including a scheduler,

wherein: the first edge node system receives a request for a computational load corresponding to a task from an external device;

the master node determines a worker node to which an application capable of performing the task is distributed using the scheduler;

the determined worker node performs the task; and

the master node responds to the external device by collecting results of performing the task.

2. The multi-cloud edge system of claim 1 , wherein the first edge node system and the near edge node system are connected to each other over a high-speed network based on a tunneling protocol.

3. The multi-cloud edge system of claim 2 , further comprising:

a shared storage device for sharing and storing data depending on a collaborative operation between the first edge node system and the near edge node system.

4. The multi-cloud edge system of claim 1 , further comprising:

a management node for controlling a resource required for a collaborative operation based on data of the first edge node system and the near edge node system.

5. The multi-cloud edge system of claim 1 , wherein:

the first edge node system or the near edge node system comprises computing nodes, and

each of the computing nodes provides a monolithic application, a micro-service, and a Function as a Service (FaaS) based on a container platform.

6. The multi-cloud edge system of claim 1 , wherein a service based on computation in vertical collaboration, provided by the core cloud and the first edge node system, and a service based on computation in horizontal collaboration, provided by the first edge node system and the near edge node system, are provided.
