overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Distributed systems refer to a model where multiple interconnected computers or nodes work together to achieve a common goal, providing scalability, fault tolerance, and resource sharing. They enable complex, large-scale applications such as cloud computing, online services, and data processing frameworks by distributing tasks across multiple machines.
Key Features
- Scalability: Ability to handle increased load by adding more nodes
- Fault Tolerance: System remains operational despite individual node failures
- Resource Sharing: Multiple nodes share resources such as storage, processing power, and data
- Concurrency: Multiple processes execute simultaneously across different nodes
- Transparency: Users perceive the system as a single cohesive entity despite its distributed nature
- Communication: Reliable message passing protocols between nodes
Pros
- Enhances system scalability to accommodate growth
- Improves reliability through redundancy and fault tolerance
- Enables large-scale data processing and analysis
- Facilitates resource sharing and cost efficiency
Cons
- Increased complexity in design and maintenance
- Challenges in ensuring consistency and synchronization
- Potential security vulnerabilities due to distributed architecture
- Difficulties in debugging and diagnosing issues
