Expert writing Tips

Best practice

When discussing system design, specify the level of "high availability" achieved (e.g., "five nines" availability of 99.999%) to quantify reliability.

Common error

Don't use "high availability" interchangeably with reliability. While related, reliability refers to the probability of failure-free operation over a period, whereas "high availability" focuses on minimizing downtime and ensuring continuous service, even with failures.

Linguistic Context

The phrase "high availability" functions as a noun phrase, where "high" modifies "availability". As Ludwig AI confirms, it is grammatically correct and used to describe systems or components designed to be continuously operational and accessible.

Ludwig's WRAP-UP

In summary, "high availability" is a grammatically correct and frequently used term referring to a system's ability to operate continuously without failure for a defined period. Ludwig AI confirms its correctness and usability. It is prevalent in scientific, news and media, and formal business contexts. To achieve "high availability", strategies like redundancy, failover mechanisms, and disaster recovery planning are essential. Quantifying the level of "high availability", for example, specifying 'five nines' is a common practice.

More alternative expressions

service uptime

Refers to the duration a service is operational, directly quantifying high availability.

continuous operation

Directly refers to the uninterrupted functioning of a system, synonymous with the goal of high availability.

zero downtime

Stresses the complete absence of service interruptions, an ideal but often challenging aspect of high availability.

fault tolerance

Focuses on the system's ability to continue operating despite failures, a key component of high availability.

FAQs

How is "high availability" typically implemented in cloud computing?

"High availability" in cloud computing is often achieved through redundancy, replication, and failover mechanisms across multiple availability zones. Cloud providers like Amazon replicate data across multiple servers within its data centres to offer "high availability".

What is the difference between "high availability" and disaster recovery?

"High availability" focuses on minimizing downtime and ensuring continuous operation, whereas disaster recovery focuses on restoring systems and data after a major disruption. One disaster recovery tool available to SMBs mentioned earlier is "high availability".

What are some common metrics used to measure "high availability"?

Common metrics include uptime percentage (e.g., 99.999% availability), mean time between failures (MTBF), and mean time to recovery (MTTR). Telcom companies in the US hold themselves to the "high availability" standard of five 9s or %99.999percentt availability.

What factors should I consider when designing a system for "high availability"?

Consider redundancy, failover mechanisms, monitoring, and disaster recovery planning. If "high availability" and/or performance are required, redundancy and fail-over options must be considered.
