1. Decentralized: Distributed systems do not have a central point of control or coordination. Instead, they consist of multiple autonomous nodes that communicate and collaborate with each other to achieve a common goal.

2. Scalability: Distributed systems are designed to scale horizontally, meaning that additional nodes can be added to the system to handle increased workload or demand. This allows for greater flexibility and capacity to handle varying levels of traffic.

3. Fault tolerance: Distributed systems are resilient to failures, as they are designed to continue functioning even if individual nodes or components fail. This is achieved through redundancy, replication, and error handling mechanisms.

4. Consistency: Maintaining consistency across distributed systems can be challenging, as data may be stored and processed on multiple nodes simultaneously. Ensuring data consistency requires careful coordination and synchronization mechanisms to prevent conflicts and inconsistencies.

5. Communication: Communication between nodes in a distributed system is typically done through message passing or remote procedure calls. This allows nodes to exchange information, coordinate tasks, and collaborate on shared resources.

6. Heterogeneity: Distributed systems often consist of nodes with different hardware, software, and network configurations. Managing this heterogeneity requires interoperability standards, protocols, and middleware to ensure seamless communication and coordination.

7. Security: Distributed systems are vulnerable to various security threats, such as unauthorized access, data breaches, and denial of service attacks. Implementing robust security measures, such as encryption, authentication, and access control, is essential to protect the system and its data.

8. Performance: Distributed systems must be designed to optimize performance and efficiency, as data processing and communication may involve multiple nodes across a network. This requires careful consideration of factors such as latency, bandwidth, and resource utilization to ensure optimal performance.
