Introduction to Distributed Computing System
A Distributed Computing System (DCS) is a network of independent computers that work together as a single system to solve complex problems. These computers communicate and coordinate through a network to perform tasks efficiently.
Distributed computing is widely used in cloud computing, parallel processing, high-performance computing, and large-scale applications like Google, Facebook, and Amazon services.
Types of Distributed Computing Systems
There are two main types of distributed computing systems based on coupling:
Tightly Coupled Systems
Loosely Coupled Systems
1. Tightly Coupled Systems
A tightly coupled system is a multiprocessor system where multiple processors share a common memory and are closely linked through high-speed interconnections.
Characteristics:
Processors share a single memory (shared memory architecture).
High-speed communication between processors.
Requires synchronization and coordination.
Used in parallel computing and supercomputers.
Examples:
Multi-core processors (Intel i7, AMD Ryzen)
Supercomputers
High-Performance Computing (HPC) clusters
Advantages:
Faster processing speed
Efficient resource sharing
Low communication overhead
Disadvantages:
Expensive to maintain
More complex synchronization required
2. Loosely Coupled Systems
A loosely coupled system consists of multiple computers connected via a network that do not share memory and communicate through messages.
Characteristics:
Each computer has its own memory and processor.
Communication happens via network protocols (e.g., TCP/IP).
Used in cloud computing, grid computing, and peer-to-peer networks.
Highly scalable and fault-tolerant.
Examples:
Cloud computing (AWS, Google Cloud, Azure)
Peer-to-peer (P2P) networks (BitTorrent)
Grid computing (SETI@home)
Advantages:
Easy to scale by adding more nodes
More fault-tolerant than tightly coupled systems
Cost-effective and flexible
Disadvantages:
Higher communication overhead
Slower than tightly coupled systems
Key Differences: Tightly vs. Loosely Coupled Systems
| Feature | Tightly Coupled System | Loosely Coupled System |
|---|---|---|
| Memory Sharing | Shared memory | Separate memory |
| Communication | High-speed interconnects | Network-based messaging |
| Scalability | Limited scalability | Highly scalable |
| Fault Tolerance | Low (failure affects entire system) | High (failures affect only one node) |
| Examples | Supercomputers, Multi-core processors | Cloud Computing, Grid Computing |
Conclusion
Both tightly coupled and loosely coupled systems have their advantages and are used in different domains.
- Tightly coupled systems are best for high-speed computations (e.g., supercomputers).
- Loosely coupled systems are ideal for scalable and distributed applications (e.g., cloud computing).
