What is the impact of dimensions on SLRs (Service level requirements) ?

Capacity

• Raw power in an element - CPU, fast network connection, or large storage capacity
• increased through vertical scaling
• can improve performance, availability, and scalability

Redundancy

• Multiple systems that work on the same job - Load balacing
• increased through horizontal scaling
• can increase performance, reliability, availability, extensibility, and scalability
• can decrease manageability and security

Modularity

• Dividing a computational problem into separate elements
• can increase scalability, extensibility, maintainability, and security
• can decrease performance, reliability, availability, and manageability

Tolerance

• Time available to fulfill a request from a user
• can increase performance, scalability, reliability, and manageability

Workload

• Computational work being performed at a particular point within the system
• consumes available Capacity
• can increase performance, scalability, and availability

Heterogeneity

• Diversity in technologies that is used within a system
• can increase performance and scalability
• can decrease performance, scalability, availability, extensibility, manageability, and security
