The goals of a Distributed System define the key objectives that guide the design and operation of multiple interconnected computers working as a unified system.
- Enable efficient resource sharing across distributed nodes.
- Provide transparency by hiding distribution complexity.
Goals of Distributed Systems
1. Resource Sharing
It is a core goal of distributed systems that allows multiple computers to access and use hardware, software, and data resources.
- Supports collaborative work and data consistency across systems.
- Distributes workload efficiently among multiple machines.
- Reduce redundancy and improve overall resource utilizatioin.
2. Transparency
This hides the complexity of multiple interconnected components and presents the system as a single platform to users.
- Manages replication without exposing multiple data copies to users.
- Masks certain failures to maintain smooth system operation.
- Improves usability by providing abstraction and simplifying interaction.
3. Scalability
It handles increasing users, data, and workload in the system.
- Supports growth in users, transactions, and data volume efficiently.
- Enables horizontal scaling by adding more machines to distribute load.
- Supports vertical scaling by upgrading hardware resources of existing machines.
4. Reliability and Fault Tolerance
This ensure that system will operate perfectly and consistenely even when some components fails.
- Recovers automatically using backup nodes or failover strategies.
- To prevent single point failures it uses redundancy and replication.
- Provides data intergrity and consistent service availability.
5. Security
It provides securtiy to data, resources andcommunication across the different connected nodes.
- Ensures authentication to verify the identity of users and systems.
- Protects confidentiality through encryption and secure storage.
- Uses secure communication protocols to safeguard data during transmission.
6. Performance Improvement
It focuses on increasing system speed, responsiveness, and overall efficiency.
- Reduces latency by processing requests closer to users.
- Increases throughput by handling multiple request at a time.
- For faster response time it optimize resource utilization.
7. Openness
This operates using standard protocols and publicly defined interfaces, allowing seamless integration of components.
- Uses standard communication protocols and APIs for system interaction.
- Supports interoperability between heterogeneous systems and platforms.
- Allows integration of third-party services and components.
8. Heterogeneity
Allows programs to operates in different hardware platforms, operating systems, network types and programming environments.
- Uses middleware and standard protocols to manage diversity efficiently.
- Allows cross-platform integration of services and applications.
- Allow continious communication despite of different technologies.
9. Concurrency
It manages different processes and users accessing shared resoures at the same time while maintaing correctness and consistency.
- Improves system efficiency and overall throughput.
- To prevent data conflicts it uses synchronization mechanisms.
- Uses coordination protocols to maintain consistency.
