Local Vs Distributed Objects
Local and distributed objects differ in many respects. Here are some of them:
- Life cycle : Creation, migration and deletion of distributed objects is different from local objects
- Reference : Remote references to distributed objects are more complex than simple pointers to memory addresses
- Request Latency : A distributed object request is orders of magnitude slower than local method invocation
- Object Activation : Distributed objects may not always be available to serve an object request at any point in time
- Parallelism : Distributed objects may be executed in parallel.
- Communication : There are different communication primitives available for distributed objects requests
- Failure : Distributed objects have far more points of failure than typical local objects
- Security : Distribution makes them vulnerable to attack.
