Availability
Description
Availability refers to the software system’s ability to remain continuously accessible and operational to support essential business functions and user expectations, especially in mission-critical scenarios.
Consistent, reliable, and timely access to data ensures operational continuity, builds user trust, and enables data-driven decision-making. High availability is particularly critical in systems where downtime directly impacts business or safety, such as e-commerce platforms, financial systems, or healthcare environments.
Risks:
- Implementing high-availability solutions like clustering, load balancing, and distributed systems increases system complexity, which can lead to higher maintenance overhead and increased likelihood of errors.
- Overlooking SPoFs (e.g., a critical database or network connection) can still lead to outages.
- Over-engineering availability for non-critical parts of the system can lead to wasted resources and effort.
