What do you understand by Latency, throughput, and availability of a system?

Answer»

Performance is an important factor in SYSTEM design as it helps in making our services FAST and reliable. Following are the three key metrics for measuring the performance:

  • Latency: This is the time taken in milliseconds for delivering a single message.
  • Throughput: This is the amount of DATA successfully transmitted through a system in a given amount of time. It is measured in bits per second.
  • Availability: This determines the amount of time a system is available to RESPOND to requests. It is calculated: System Uptime / (System Uptime+Downtime).
