- Modern applications
3. 🧩 Key Factors Contributing to Complexity
🔑 1. Heterogeneity (Diversity of Systems)
-
Different:
- Hardware
- Software
- Operating systems
📊 Example: Windows + Linux + Cloud systems working together
🔑 2. Scalability Requirements
- Systems must grow with demand
🔑 3. Security Challenges
- Increasing cyber threats
- Need for advanced protection
🔑 4. Dynamic Workloads
- Workloads change frequently
- Systems must adjust in real-time
🔑 5. Virtualization
- Multiple virtual systems on one physical system
🔑 6. Cloud Computing
-
Mix of:
- Public cloud
- Private cloud
- Hybrid cloud
🔑 7. Mobility
- Access from mobile devices
- Remote work environments
4. ⚠️ Challenges Due to Complexity
🔧 1. Difficult Management
- Hard to monitor all systems
🔧 2. Higher Risk of Failures
- More components = more chances of failure
🔧 3. Security Risks
- More entry points for attackers
🔧 4. Integration Issues
- Systems may not work well together
🔧 5. Cost Management
- Expensive to maintain complex systems
🔧 6. Performance Issues
- System slowdowns due to overload
5. ⚙️ Managing Complexity
✅ Key Strategies
🔹 1. Automation
