What is the Remote Instance ?
WideStudio enables an instance existing on a remote computer running
WideStudio to be called on, the same way as if it exists on the local
computer. The remote instance feature covers the following:
Accessing a remote instance is performed by using a remote instance
acquired with an object management, in the same way of accessing an
usual instance acquired by WSCGIappObjectList() object management.
In calling a remote instance existing on the same computer, the agent
running on the same computer obtains a remote instance to be called.
In calling a remote instance existing on a remote computer, the agents
running on each computer exchange information of remote instances to
get and be called.
- Distributed Computing
An instance (object) of the WideStudio application on a remote
computer can be accessed in the same manner as an instance
(object) on the local computer, for easy distributed computing.
Large scale WideStudio applications can be designed with the
functionality to separate tasks into multiple processes, each
operating and collaborating with each other.
- Seamless distribution over network
Instances of the WideStudio on remote computers over a
network can be seamlessly referred to without worrying their
whereabouts. Agents running on each computer manage remote
instances existing on their local systems and exchange
information among other agents, keeping any remote instance
WideStudio applications automatically access remote instances
without allocating to their whereabouts, plugging into the
correct remote instances.
- Fault tolerance improvement
WideStudio applications can be run with multiplexing. For
example, when one application out of the multiplex goes down, an
agent detects it and interchanges the remote instance with
another WideStudio on a remote computer.
As for the WideStudio application, it can access the remote
instance without being aware of its exchange by multiplexing.
