Centralized Architecture

• All computing functions managed from a single location or authority
• Components
  • Central Server
  • Mainframe
  • Data Center
• Data and applications stored in one place, accessed via a network

Benefits:

• Efficiency and Control — High resource control and efficient resource allocation
• Consistency — Ensures uniform and accurate data across the organization
• Cost-effective — Reduced maintenance and infrastructure costs

Risks

• Single Point of Failure — Server failure can disrupt the entire network
• Scalability Issues — Struggles to handle growth, leading to performance problems
• Security Risks — Attractive targets for cybercriminals; compromised server risks data and app security

Decentralized Architecture

• Computing functions distributed across multiple systems or locations
• No single point of control; each node operates independently

Benefits:

• Resilience — Can continue functioning despite individual node failures
• Scalability — Easily scales with organization growth by adding new nodes
• Flexibility — Supports remote work and distributed teams

Risks:
