Resilience and Fault Tolerance
In order to guarantee system availability and reliability, it is crucial to design fault tolerance and resilience. Techniques like redundancy, replication, and fault detection algorithms are used in this. System downtime can be avoided or minimized by designing systems that can survive component failures and gracefully handle exceptions, hence minimizing the impact of failures. System resilience is further improved by putting backup and recovery procedures in place and conducting careful testing and monitoring.
Design Principles in System Design
Design Principles in System Design are a set of considerations that form the basis of any good System. But the question now arises why use Design Principles in System Design? Design Principles help teams with decision-making, and is a multi-disciplinary field that involves trade-off analysis, balancing conflicting needs, and making decisions about design choices that will impact the overall system.
Some of the most common Design Principles in System Design are:
- Separation of Concerns
- Encapsulation and Abstraction
- Loose Coupling and High Cohesion
- Scalability and Performance
- Resilience to Fault Tolerance
- Security and Privacy
Let us explain each design principle to get a better understanding of the same as follows:
