FOGR physical implementation

FOGR network is also an example of physical fog computing platform. FOGR network uses a new management protocol called DCPP. DCPP is a remote, simple and efficient host management protocol. The traditional deployment method is to install applications through plug-ins or scripts. The disadvantage of this is that the operation, configuration, management and all life cycles of the application will be bound with the current operating system. This has many disadvantages. The way of creating virtual machine can also realize some functions, but the virtual machine is very heavy and is not conducive to portability.

A better solution is to deploy containers. Each container is isolated from each other. Each container has its own file system. Processes between containers will not affect each other and can distinguish computing resources. The container can be deployed quickly. Because the container is decoupled from the underlying facilities and machine file system, it can be migrated between different clouds and different versions of operating systems.

Containers occupy less resources and deploy quickly. Each application does not need to be combined with other application stacks, nor does it depend on the infrastructure of the production environment, which enables a consistent environment from R & D to testing and production. Similarly, containers are lighter and more "transparent" than virtual machines, which is easier to monitor and manage.

Therefore, the DCPP protocol based on kubernetes has the following advantages:

Portable: supports multiple types of computing modes

Extensibility: modularization, plug-in, free mount combination

Automation: automatic deployment, replication, restart and capacity expansion.
