Distributed System

 Distributed System: Collection of multiple individual system connected through a network that share resources, communicate and coordinate to achieve goals.

Advantages:

1. Scalable - we can horizontally scalable by adding more machine / replica to improve its capability.

2. No single point of failure - Replicas will support ,if system fails.

3. Low Latency - If system is distributed , we can put system anywhere in a region .

                            If system is centralized ,it will be at one place only.

Disadvantages:

1. Complex: Distributed System has so many servers and nodes, so it  is complex.

2. Management Requirement: Additional Detail Required for so many server /nodes to get connected , when  network is said to be distributed .

3. Difficult to secure.

4. Message may be lost in between nodes.
