@Vikas_Dhillon could you pls answer this ques ?

For VRT, we can say it is reliable based on answers to below questions:

  • Would VRT be able to work correctly when one of the services stops working because of a hardware problem? - Yes, we use autoscaling, horizontal.
  • VRT be able to work correctly when the traffic is tripled or quadrupled? - Yes, Horizontal autscaling.
  • VRT be able to work correctly when you experience a DDoS attack? - Yes, our VRT are security certified and tested for DDoS attack.
  • Is the rate of successful end-user requests more than 99%? - Yes, as per the configuration.

So, we can say that our VRT is reliable.

@Dilip_Vishwakarma I would like to differ from you a quick search on Internet will show these are the measurable metrics of a reliable system

  1. Uptime: The percentage of time that a system is operational and available for use.

  2. Mean Time Between Failures (MTBF): The average time interval between system failures.

  3. Mean Time to Repair (MTTR): The average time required to repair a failed system and restore it to full functionality.

  4. Availability: The proportion of time that a system is operational and accessible to users within a specified time period.

  5. Failure Rate: The frequency at which components or the system as a whole fail within a given timeframe.

  6. Reliability Growth: The improvement in system reliability over time as issues are identified and addressed through testing, maintenance, and updates.

  7. Redundancy Levels: The degree to which critical components or functions are duplicated within the system to mitigate the impact of failures.

  8. Service Level Agreement (SLA) Compliance: The extent to which the system meets agreed-upon performance standards and uptime targets outlined in SLAs.

Claiming any system reliable or not should be backed by these parameters so I would request you to share the parameters for Vahana. Without the exact matrix, these are just assumptions

When we talk about reliability, it’s important to ensure that all components are reliable, not just one area. For example, vLog is not reliable; it often doesn’t work on Sandbox/CUG, and we often have to perform manual work to make it function.
