In IT and systems engineering, the degree to which a system or service is operational and accessible when needed. One of the key metrics for measuring system reliability.
システムの可用性を高める。
We improve the availability of the system.
可用性99.9%を目標にしている。
We are targeting 99.9% availability.
冗長構成により高い可用性を実現した。
We achieved high availability through redundant configuration.
可用性 is a technical IT term referring to system uptime and accessibility.
COMMON COLLOCATIONS:
- 高可用性: high availability (HA)
- 可用性を確保する: to ensure availability
- 可用性を向上させる: to improve availability
RELATED CONCEPTS:
- 信頼性: reliability
- 耐障害性: fault tolerance
- 冗長性: redundancy
TECHNICAL NOTE:
Availability is often expressed as a percentage (e.g., 99.9% = "three nines"). The term is part of the IT triad of 機密性 (confidentiality), 完全性 (integrity), and 可用性 (availability), known as CIA.
