== Local vs Distributed Objects ==

Local and distributed objects differs in many dimentions<ref>W. Emmerich (2000) Engineering distributed objects, John Wiley & Sons Ltd.</ref> here is some of them:

# Life cycle : Creation, migration and deletion of distributed objects is different from local objects.

# Reference : Objets reference of distributed objetcs are more complex than simple pointer to memory adress.

# Request Latency : A distributed objects request is orders of maginitude slower than local method invocation.

# Object Activation : Distributed objects may not always be advailable to serve and object request at any point in time.

# Parallelism : Distributed object may be executed in parallel.

# Communication : there are different communication primitive available for distributed objects requests.

# Failure : Distributed object have a lot more point of failure than typical local objects

# Security : Distribution make it vulnarable for security attacks and so on.
