Reliability:

• The distributed system should be reliable and continue to operate correctly even in the event of hardware or software failures. 
• Redundancy, fault tolerance, and error-handling mechanisms are essential to ensure the system's reliability.

 

Performance: 

• Distributed systems should be designed to achieve good performance. 
• The performance of the system can be improved by reducing communication overhead, optimizing data access, and load balancing.

 

Safety: 

• Safety is an important design requirement for distributed systems. 
• The system should be designed to ensure the safety of users, data, and resources.

 

Security: 

• Security is critical in distributed systems to protect against unauthorized access, data theft, and other security threats. 
• Access control, authentication, and encryption mechanisms can help to ensure the security of the system.

 

Fault tolerance: 

• Fault tolerance is an important requirement in distributed systems to ensure that the system continues to function correctly even in the event of hardware or software failures. 
• Techniques such as redundancy and error handling can be used to improve fault tolerance.

 

Maintainability: 

• It is essential to design distributed systems that are easy to maintain and update. 

 

Balancing of Computational Loads: 

• In distributed systems, it is essential to balance computational loads across multiple nodes to ensure that no node is overloaded and that the system operates efficiently.

 

Caching and Replication: 

• Caching and replication are important techniques used to improve the performance and reliability of distributed systems. 
• Caching involves storing frequently accessed data in memory or on disk to reduce access times, while replication involves duplicating data across multiple nodes to ensure its availability in the event of failures.

 

Availability: 

• Availability refers to the ability of a distributed system to provide access to its resources and services whenever required. 
• A distributed system should be designed to ensure high availability, even in the event of failures or network disruptions.

 

Responsiveness: 

• Distributed systems should be designed to provide fast and responsive services to users.
• The system should be able to handle large volumes of requests and provide timely responses to users.

 

Adaptability: 

• Distributed systems must be adaptable to changing conditions such as changes in workload, network topology, or hardware failures. 
• The system should be able to dynamically adapt to these changes to continue to provide the required services.

 

Resource Availability: 

• Distributed systems should be designed to make efficient use of available resources such as processing power, memory, and network bandwidth. 
• Resource allocation and management algorithms can help to optimize resource usage.

 

Integrity: 

• Integrity is another important design requirement that deals with the consistency and accuracy of data. 
• Distributed systems should be designed to ensure data integrity, even in the presence of faults or malicious attacks.
