Operational Performance
Operational performance is a reflection of how well a service meets the expectations of its users. It's about ensuring that the service is available when needed and performs optimally.
Uptime:
A vital metric that measures the amount of time a system remains operational, usually represented as a percentage of the total possible operating time over a specified period, like a month or year.
| Uptime | Allowed downtime per year | per month |
|---|---|---|
95 % | 18.25 days | 1.5 days |
99 % | 3.65 days | 7.2 hours |
99.5 % | 1.83 days | 3.6 hours |
99.9 % | 8.76 hours | 10.1 minutes |
99.99 % | 52.6 minutes | 4.23 minutes |
99.999 % | 5.26 minutes | 25.9 seconds |
Other Indicators:
Latency: The time it takes to process a request or the delay in response, which should be minimized for optimal user experience.
Performance: Often gauged through metrics like response time, throughput, and error rates to ensure the system is working efficiently.
Scalability: The system’s ability to handle increased load without adverse effects on performance and user experience.
These metrics are fundamental to ensuring that the system or service is reliable and meets user expectations. They directly impact the user experience and, consequently, customer satisfaction.
